How Long Does Bronchiolitis Last? When Symptoms Usually Peak and Why the Cough Lingers

It is a little after three in the morning, and a father is sitting on the edge of the crib mattress with his phone flashlight pointed at the ceiling so he can watch his ten-week-old daughter breathe. Two days ago it was a runny nose. Tonight there is a cough that sounds wet and small, a faint whistle on each breath out, and a bottle she took only halfway. He is counting breaths against the clock, and typing the question every parent in this position eventually types: how long does bronchiolitis last?

The honest answer is more useful than a single number. Bronchiolitis has a recognizable shape. It builds, it peaks, and it fades on a schedule that is surprisingly predictable, with one stubborn exception: the cough, which routinely outstays everything else by weeks.

This explainer walks through that shape, what is actually happening inside those tiny airways, why some babies need a closer watch than others, and the specific signs that mean it is time to stop counting and call.

How long does bronchiolitis last in babies?

Most cases of bronchiolitis in babies run their course in about one to two weeks. The NHS describes symptoms that are usually at their worst between the third and fifth day of the illness and that generally clear within two to three weeks, while the Cleveland Clinic notes that a cough can hang on for up to four weeks after everything else has settled. Those two facts, taken together, explain almost every parental confusion about this illness: the scary part is short, but the audible part is long.

Bronchiolitis is a viral infection of the bronchioles, the smallest branching air passages deep in the lungs, and it mainly affects children under two, with the highest rates in the first year. Because a baby’s bronchioles are only a millimeter or two across, a small amount of swelling and mucus does what the same swelling would never do in an adult: it narrows the passage enough to make breathing noticeably harder work.

The illness typically opens like an ordinary cold. Runny nose, mild cough, sometimes a low-grade fever. Over the next two or three days the infection moves lower, the cough becomes more persistent, breathing may quicken, and a wheeze or crackle can appear. Then, for most babies, the tide turns. Breathing eases first, appetite returns next, and the cough becomes the last thing standing.

Timelines here are typical ranges drawn from guideline-level sources, not promises. A premature baby, a very young infant, or a child with a heart or lung condition may follow a slower or bumpier curve, and every family’s experience will be shaped by the child in front of them. What the ranges do offer is a map, so that day four feels like a known landmark rather than an alarming surprise.

What actually happens inside a baby's airways

Picture the lungs as an upside-down tree. The trachea is the trunk, the bronchi are the main branches, and the bronchioles are the twigs, thousands of them, each ending in clusters of air sacs where oxygen crosses into the blood. Bronchiolitis is an infection of the twigs.

When a respiratory virus lands in a baby’s nose, it multiplies in the cells lining the nasal passages and, over a few days, travels down the airway. In the bronchioles, the virus damages the cells that line the tube. The body’s response is inflammation: the lining swells, extra mucus is produced, and dead cells slough off into the passage. In an adult, a bronchiole with a slightly thickened wall barely registers. In an infant, that same thickening can shrink the working diameter of an already narrow tube by a large fraction, which is why a baby with a modest infection can sound and look far more unwell than an older sibling with the same virus.

Narrowed twigs do two things. Air moving through them makes noise, which is the wheeze parents hear on the out-breath and the fine crackles a clinician may hear through a stethoscope. Some air also gets trapped behind mucus plugs, so the baby breathes faster and works harder to move enough oxygen. That extra effort shows up as flaring nostrils, a belly that pulls in sharply under the ribs, and a baby too busy breathing to feed comfortably.

The Mayo Clinic notes that the cough is essentially the lungs’ cleanup crew, pushing mucus and debris upward and out. That is also why suppressing it is not a goal in infants. The airway lining then regrows over days to weeks, which, as a later section explains, is the real reason the cough persists after the child is otherwise well.

Is bronchiolitis the same as RSV?

Not quite, and the distinction is worth one clear sentence. Bronchiolitis is a pattern of illness, an infection and inflammation of the small airways. RSV, short for respiratory syncytial virus, is the germ that most often causes that pattern. One is the diagnosis, the other is the culprit.

RSV is remarkably common. According to the CDC, almost all children have been infected with it by their second birthday, and for most of them it produces nothing worse than a cold. In a subset of infants, though, RSV reaches the bronchioles and produces the classic picture of bronchiolitis. The CDC estimates that RSV leads to roughly 58,000 to 80,000 hospitalizations each year among children under five in the United States, and that about one to two of every one hundred infants under six months who catch RSV may need hospital care. Those figures make RSV the single most important cause of bronchiolitis, but not the only one.

Other viruses can produce an identical illness. Rhinovirus, the common-cold virus, is a frequent second cause. Human metapneumovirus, parainfluenza viruses, adenovirus, influenza, and several coronaviruses have all been found in infants with bronchiolitis, per the Cleveland Clinic and MedlinePlus. From the outside, a parent cannot tell them apart, and in most cases the clinician does not need to. Testing for a specific virus is sometimes done in hospitals to guide infection-control decisions or when the picture is unusual, but the treatment for bronchiolitis is the same whichever virus is responsible.

So when a nurse says “RSV bronchiolitis,” both halves are informative: the first names the virus, the second describes where it has settled and what it is doing. When a chart just says “bronchiolitis,” it usually means the illness pattern has been recognized and the exact virus either was not tested or would not change the plan.

What can trigger bronchiolitis, and why some babies are hit harder

The trigger is always a virus, and the delivery route is almost always another person. An older sibling home from day care with a runny nose, a parent with what feels like a mild cold, a well-meaning relative who kisses the baby’s face: these are the ordinary pathways. According to the CDC, RSV spreads through droplets from coughs and sneezes, through direct contact such as kissing, and through touching surfaces where the virus can survive for hours before someone touches a baby’s face.

Bronchiolitis is strongly seasonal in temperate climates, with most cases clustering in the fall, winter, and early spring months when respiratory viruses circulate most, per the Mayo Clinic. Patterns can shift from year to year, and clinicians track local activity rather than the calendar.

Why one baby gets a cold and another gets bronchiolitis comes down to the airways and the immune system rather than the virus itself. Several factors raise the odds of a more significant illness, according to the Mayo Clinic and MedlinePlus:

• Age under about three months, when airways are narrowest and immune defenses least practiced.
• Premature birth, particularly before 37 weeks, because lung development was interrupted.
• Chronic lung disease, congenital heart disease, or a weakened immune system.
• Exposure to tobacco smoke in the home, which irritates airway linings.
• Crowded living conditions or day care attendance, which raise the number of viral exposures.
• Never having been breastfed, since breast milk passes along some protective antibodies.

None of these is a verdict. Plenty of full-term, breastfed babies in smoke-free homes still get bronchiolitis, and many premature infants sail through with a mild case. What the list does is help a clinician decide how closely a particular baby should be watched, which is the subject of a later section.

When do bronchiolitis symptoms peak? A day-by-day picture

Parents often describe the same disorienting sequence: the baby seemed to be getting a cold, then seemed to be getting better, then on the third or fourth night suddenly seemed much worse. That is not imagination. It is the natural arc of the illness, and the NHS puts the peak squarely between days three and five.

The table below summarizes what guideline-level sources describe as a typical course. Individual babies vary, and the day counts are approximate ranges, not a schedule to hold a child to.

Stage	Typical timing	What parents commonly notice
Incubation	About 4 to 6 days after exposure (CDC)	No symptoms yet; baby seems well
Early cold phase	Days 1 to 2	Runny or stuffy nose, mild cough, sometimes low fever, slightly fussier feeding
Peak	Days 3 to 5 (NHS)	Persistent cough, faster breathing, wheeze or crackles, more effort to breathe, feeds shorter or refused
Turning point	Roughly days 5 to 7	Breathing gradually eases, appetite starts to return, sleep improves
Recovery	Weeks 2 to 3 (NHS)	Most symptoms resolved; residual cough, occasional wheeze with exertion or crying
Lingering cough	Up to about 4 weeks (Cleveland Clinic)	Cough alone, baby otherwise well, feeding and playing normally

Two practical points follow from this shape. First, a baby seen by a clinician on day two who is judged mild may still get worse before getting better, so a plan for what to watch over the next 72 hours matters more than the reassurance on the day. Second, the peak is when hospital visits cluster, because feeding and breathing are hardest then. A baby who reaches day six or seven with easier breathing and improving feeds has, in most cases, passed the most demanding stretch.

Why does the bronchiolitis cough linger for weeks?

The cough is the part that erodes a parent’s confidence. The fever is gone, the baby is smiling and feeding, and yet three weeks on there is still a rattling cough at bedtime. Is something still wrong? Almost always, no. The cough is the sound of repair.

Bronchiolitis damages the cells lining the bronchioles. Some die and are shed; the ones that remain are inflamed and unusually sensitive. Rebuilding that lining is slow, and while it is under way the airway does two things that produce a cough. It continues to make mucus that has to be cleared, and its irritated nerve endings fire more readily in response to cold air, crying, feeding, or lying flat. Each of those triggers sets off a protective cough reflex that, in a healthy airway, would have stayed quiet.

The NHS notes that while most symptoms clear within two to three weeks, the cough can persist for several weeks, and the Cleveland Clinic gives up to four weeks as a typical outer range. National guidance from the United Kingdom summarizes the same evidence: in roughly nine of ten children the cough has resolved by three weeks. That leaves one in ten still coughing beyond that point without anything being wrong, a fact worth knowing before week four arrives.

A lingering cough is generally reassuring when the baby is otherwise well: feeding normally, breathing comfortably at rest, sleeping in stretches, gaining weight, and active while awake. It becomes a reason for review when it is getting worse rather than slowly better, when it is joined by a new fever, when breathing effort increases again, or when it stretches past about four weeks without clear improvement. In those situations a clinician may want to check for a second infection or a different explanation. The decision about whether and when to look further sits with the treating team, but the timeline gives parents a reasonable point at which to ask.

Is bronchiolitis contagious, and for how long?

Bronchiolitis itself is not passed from person to person; the virus behind it is. That distinction matters because what a baby transmits to a sibling or grandparent is usually a cold. Whether the recipient develops bronchiolitis depends on their own age and airways, which is why an infant can catch RSV from a toddler with a mild sniffle.

According to the CDC, people infected with RSV are usually contagious for three to eight days, and they may spread the virus for a day or two before symptoms appear. Some infants and people with weakened immune systems can continue shedding virus for up to four weeks, even after they appear recovered. The virus travels in respiratory droplets, through direct contact such as kissing, and on surfaces like doorknobs and toys, where the CDC notes it can survive for many hours.

Those facts translate into simple household habits that reduce, though never eliminate, the risk of a baby being exposed. Handwashing with soap for at least twenty seconds before handling the baby. Keeping anyone with cold symptoms, including affectionate relatives, from kissing the baby’s face or sharing cups and pacifiers. Wiping frequently touched surfaces during cold season. Keeping the baby’s environment free of tobacco smoke. Covering coughs and sneezes.

Prevention has also moved beyond hygiene. The CDC now describes two ways to protect infants against severe RSV disease: an immunization given to the pregnant parent late in pregnancy, which passes antibodies to the baby, and a long-acting monoclonal antibody, a laboratory-made protective protein, given directly to eligible infants. Both are aimed at RSV specifically, not the other viruses that can cause bronchiolitis, and both come with eligibility criteria and timing that depend on the individual baby. Whether either is appropriate is a conversation for the family’s pediatric clinician, who can weigh the child’s age, health, and the season.

Which babies are watched more closely, and which are usually managed at home

The overwhelming majority of babies with bronchiolitis never see the inside of a hospital. The NHS and the Mayo Clinic both describe a mild, self-limiting illness in most children, managed at home with comfort, fluids, and a watchful adult. Clinicians reserve closer monitoring for the babies whose age or health makes a steep dip at the peak more likely, and for any baby whose breathing or feeding has already crossed a line.

Babies who are typically flagged for closer follow-up, according to the Mayo Clinic and MedlinePlus, include those under about three months, those born prematurely, and those with underlying heart disease, chronic lung disease, neuromuscular conditions, or weakened immunity. For these children a clinician may schedule an earlier recheck, give more specific feeding thresholds, or have a lower bar for referral.

Admission to hospital is usually considered when a baby is struggling rather than simply symptomatic: taking well under half their usual feeds, showing signs of dehydration, breathing very fast or with visible effort, having pauses in breathing, or needing supplemental oxygen because their blood oxygen level has dropped. In hospital, care is still supportive, but it can include oxygen, help with feeding through a small tube into the stomach, fluids into a vein if needed, and continuous monitoring through the peak days.

Who is asked to wait? In a sense, most families are. A baby assessed on day two as mild is often sent home with a safety-net plan rather than a treatment, because there is no medicine that shortens the illness, and because the majority will turn the corner on their own by day five to seven. The waiting is active, not passive: the plan should name the specific signs that would bring the family back, and how to reach help at any hour. If a plan like that has not been offered, it is fair to ask for one.

How is bronchiolitis treated, and why antibiotics do not help

There is no medicine that clears bronchiolitis. That sentence surprises many parents, but it is the settled position of major guidelines, and it shapes everything about care. Because the cause is a virus, antibiotics, which kill bacteria, have no effect on the illness and are not recommended unless a clinician suspects a separate bacterial infection has developed, per the Mayo Clinic and MedlinePlus.

Treatment is therefore supportive: helping the baby breathe, eat, and rest while the immune system does the work. At home that usually means:

• Keeping the nose clear before feeds and sleep, often with saline drops followed by gentle suction, so the baby can breathe while sucking.
• Offering smaller, more frequent feeds, since a baby working hard to breathe tires quickly at the breast or bottle.
• Watching hydration by counting wet diapers.
• Keeping the air free of smoke and keeping the baby upright while awake and supervised.
• Using a fever-reducing medicine only if a clinician has advised it for the child’s age and weight.

Several treatments that seem logical have been studied and found not to help most infants. Inhaled bronchodilators, the airway-relaxing medicines used for asthma, do not reliably improve outcomes in bronchiolitis because the narrowing comes from swelling and mucus rather than muscle tightening. Oral or inhaled corticosteroids, which reduce inflammation, have likewise not shown consistent benefit in typical cases. Cough and cold medicines are not recommended for young children at all. A clinician may still choose to try a specific therapy in a specific child, and that decision belongs to them.

In hospital, the toolkit expands but stays supportive: supplemental oxygen when blood oxygen is low, feeding support through a small tube, and intravenous fluids if the baby cannot keep up by mouth. The aim is to carry the child safely through the peak, not to shorten it, because nothing yet does.

Bronchiolitis vs bronchitis: which is more serious?

The words share a root and cause endless mix-ups, but they describe different illnesses in different people. Bronchitis is inflammation of the bronchi, the larger airways closer to the trunk of the lung tree. Bronchiolitis is inflammation of the bronchioles, the fine twigs. The suffix “-itis” simply means inflammation, so the only difference in the names is which level of the airway is involved, and that difference turns out to matter a great deal.

Acute bronchitis mostly affects older children and adults. It is usually viral, produces a hacking, often mucus-producing cough, and can last a few weeks, but it rarely causes trouble getting enough oxygen because the larger airways have plenty of room to spare even when swollen. Bronchiolitis mostly affects infants, and because their smallest airways have almost no room to spare, the same degree of swelling can cause fast breathing, wheeze, and feeding difficulty.

Which is more serious? In the sense that matters to a parent, bronchiolitis carries the greater short-term risk, simply because the patients are so small and their reserves so limited. According to the CDC, RSV, the leading cause of bronchiolitis, is the most common reason for hospitalization in infants under one year in the United States. Acute bronchitis in an otherwise healthy adult, by contrast, is unpleasant but almost never dangerous.

Two caveats keep this honest. Bronchitis can be serious in adults with existing lung disease such as COPD, where a viral flare can tip an already-strained system. And most bronchiolitis is mild. The comparison is about who is at risk of a hard week, not a ranking of which diagnosis is worse in every case. A useful way to hold it: bronchitis is a bigger airway in a bigger person, and bronchiolitis is a tinier airway in a tinier person, which is exactly why clinicians take the second one seriously.

What the next two to four weeks usually look like

Once the peak has passed, recovery from bronchiolitis follows a fairly consistent order, and knowing the order helps a family recognize progress even when the cough insists nothing has changed.

Breathing eases first. Around days five to seven, the rate slows, the nostril flaring stops, and the pull-in under the ribs softens. Nights become less tense. Appetite comes back next, often over a few days rather than all at once; a baby who was taking half feeds may return to full volumes gradually, and catch-up feeding is common. Sleep settles as the nose clears and breathing quiets, though a coughing fit on lying down can still interrupt the first stretch of the night for a while.

Then the plateau. Weeks two through four are the cough-only phase described earlier, when the baby is essentially well but noisy. Some infants also wheeze briefly when they cry hard or after a feed, because the healing airways remain twitchy. The NHS notes that most symptoms have gone by two to three weeks, and the Cleveland Clinic gives up to four weeks for the cough.

A few longer-term points come up in follow-up conversations. Children who have had bronchiolitis, particularly a hospital-level episode, are somewhat more likely to have episodes of wheezing with colds over the next few years, according to the Mayo Clinic. The evidence does not settle whether bronchiolitis causes this or simply identifies children whose airways were already prone to react, and most of these children do not go on to develop asthma. A single bronchiolitis illness does not confer lasting immunity either; the CDC notes that repeat RSV infections happen throughout life, though later episodes are usually milder because the airways are larger.

Day care and contact with other babies can generally resume when the child is feeding well, breathing comfortably, and free of fever, keeping in mind the virus may still be shed for a while. The treating clinician can advise on the individual child.

What people often get wrong about bronchiolitis

Some misunderstandings about this illness are harmless. A few are not. These are the ones that clinicians hear most often, corrected against what the evidence actually shows.

“The doctor said it was mild, so we are past the worst.” Not necessarily. A baby seen on day one or two is often genuinely mild at that moment and may still worsen toward the day three-to-five peak. The reassurance is real; the timeline still applies.

“A cough that lasts three weeks means it has turned into something else.” Usually it means the airway lining is still healing. Roughly one in ten children is still coughing beyond three weeks, and a lingering cough in an otherwise well, feeding, active baby is expected. New fever, worsening breathing, or a cough getting worse rather than better are the things that change that assessment.

“Antibiotics would clear it faster.” Bronchiolitis is viral. Antibiotics do nothing against the virus, and the Mayo Clinic notes they are reserved for a suspected bacterial complication.

“Honey soothes a baby’s cough.” Honey should never be given to a child under one year because of the risk of infant botulism, a rare but serious illness, per the CDC. Over-the-counter cough and cold medicines are also not recommended for young children.

“Bronchiolitis and bronchitis are the same thing.” They affect different airways in different age groups, as the earlier comparison explained.

“If it is RSV, it must be dangerous.” Almost every child catches RSV by age two, and for the great majority it is a cold. Severe RSV bronchiolitis is the exception that gets the headlines.

“A steamy bathroom or a humidifier will fix the breathing.” Moist air can be comforting, but evidence that it changes the course of bronchiolitis is lacking, and hot steam carries a burn risk. Cool-mist devices, if used, need daily cleaning to avoid growing mold.

Questions to ask your care team

The most useful conversation at a bronchiolitis visit is not about the diagnosis, which is usually straightforward, but about the plan for the next few days. Parents who leave with clear answers to the following tend to feel steadier through the peak, and clinicians generally welcome the questions.

• Roughly what day of the illness do you think my baby is on, and when would you expect the peak?
• What specific signs should bring us back or make us call, and is there a number we can reach at night?
• How much less than usual can my baby drink before you would want to know, and how many wet diapers should we expect in a day?
• How can I tell fast breathing from normal fast breathing in a baby this age? Can you show me what pulling-in under the ribs looks like?
• Is there anything about my baby’s history, such as prematurity or a heart condition, that makes you want to see us again sooner?
• Should I use saline and suction before feeds, and how often is too often?
• Is a fever-reducing medicine appropriate for my baby’s age, and when would you want to know about a temperature?
• When can my baby return to day care or be around other infants?
• If the cough is still there at three or four weeks, do you want to see us, or is that expected?
• Are there ways to protect my baby, or a future baby, from severe RSV that we should discuss before the next respiratory season?

Writing the answers down in the moment helps. So does asking the clinician to demonstrate, on the baby, what normal and concerning breathing effort look like, because a picture in the mind at three in the morning is worth more than any description on a leaflet. Every decision about testing, treatment, and follow-up rests with the treating team, and these questions are the way to understand the reasoning behind it.

When to call your doctor

Most babies with bronchiolitis can be cared for at home, but the illness can shift quickly at the peak, and there are signs that should never wait for morning. Trust the instinct that something is off; clinicians would far rather see a baby who turns out to be fine than miss one who is not.

Call emergency services or go to the nearest emergency department immediately if a baby:

• Has pauses in breathing, or stops breathing for more than a few seconds.
• Has lips, tongue, or the skin around the mouth that look blue, gray, or unusually pale.
• Is grunting with each breath, or is working so hard to breathe that the skin pulls in sharply under the ribs or at the base of the neck.
• Is very drowsy, floppy, hard to wake, or not responding as usual.
• Is breathing very fast, generally more than about 60 breaths a minute at rest in an infant, per MedlinePlus and the Cleveland Clinic.

Contact the pediatric clinician or an urgent care service the same day if a baby:

• Is taking less than half their usual amount over two or three feeds, or refusing feeds.
• Has had no wet diaper for 12 hours or more, or noticeably fewer than usual, per the NHS.
• Is under three months old and has a temperature of 100.4°F (38°C) or higher.
• Has a fever that returns after settling, or a cough that is getting worse rather than slowly better.
• Seems more irritable, more tired, or simply not themselves in a way that worries the adults who know them.

Bronchiolitis is a diagnosis made by a clinician who has examined the child. This list is a guide to when that examination should happen, not a tool for deciding at home what the illness is or how severe it is. When in doubt, the safest step is always to make the call and let the treating team decide.

Frequently asked questions

How long does bronchiolitis last in a baby?

Typically one to two weeks for the main illness, with the cough often lasting longer. The NHS describes symptoms peaking around days three to five and most clearing within two to three weeks, while the Cleveland Clinic notes the cough can persist for up to four weeks. Babies who are premature or very young may follow a slower course, and the treating clinician can advise on what to expect for a particular child.

Is bronchiolitis the same as RSV?

No. Bronchiolitis is the illness, an infection and swelling of the smallest airways in the lungs, and RSV is the virus that most often causes it. Other viruses, including rhinovirus, human metapneumovirus, parainfluenza, adenovirus, and influenza, can produce the same picture. Because treatment is supportive whichever virus is involved, clinicians often do not need to test for the specific cause unless it would change infection-control or care decisions.

Is bronchiolitis contagious?

The viruses that cause it are. According to the CDC, people with RSV are usually contagious for three to eight days and can spread it a day or two before symptoms start; some infants shed virus for up to four weeks. The virus travels through droplets, direct contact such as kissing, and contaminated surfaces. What a baby passes on is usually a cold; whether it becomes bronchiolitis depends on the recipient’s age and airways.

Is bronchiolitis more serious than bronchitis?

In the short term, usually yes, because bronchiolitis affects infants whose tiny airways have almost no room to spare, while bronchitis affects larger airways in older children and adults. RSV bronchiolitis is the leading cause of hospitalization in infants under one in the United States, per the CDC. That said, most bronchiolitis is mild and managed at home, and bronchitis can be serious in adults with existing lung disease.

What can trigger bronchiolitis?

A respiratory virus, almost always caught from another person, is the trigger. RSV is the most common, followed by rhinovirus and several others. Babies under three months, those born prematurely, those with heart or lung conditions or weakened immunity, and those exposed to tobacco smoke or crowded settings are more likely to develop a significant illness rather than a simple cold, according to the Mayo Clinic and MedlinePlus.

What are the typical RSV bronchiolitis symptoms in the first few days?

It usually starts like a cold: runny or stuffy nose, mild cough, sometimes a low fever. Over two to three days the cough becomes more persistent, breathing may quicken, and a wheeze or crackle can appear, often with shorter or refused feeds. This is a description of the typical course, not a self-diagnosis tool; a clinician who examines the baby makes the diagnosis and judges how closely to monitor.

Why does my baby still have a cough three weeks after bronchiolitis?

Because the airway lining is still repairing itself. Damaged bronchioles keep producing mucus and remain sensitive to cold air, crying, and lying flat, each of which sets off a protective cough. Guideline evidence suggests about nine in ten children have stopped coughing by three weeks, leaving one in ten still coughing without anything being wrong. A cough that is worsening, joined by new fever, or lasting well past four weeks warrants review.

Do antibiotics help bronchiolitis?

No. Bronchiolitis is caused by viruses, and antibiotics act only on bacteria, so they do not shorten the illness or ease breathing. The Mayo Clinic notes they are reserved for cases where a clinician suspects a separate bacterial infection, such as an ear infection or pneumonia, has developed. Care is supportive: nasal clearing, smaller frequent feeds, hydration, and, when needed in hospital, oxygen and feeding support.

When can a baby go back to day care after bronchiolitis?

Generally when the baby is feeding well, breathing comfortably, and free of fever, though the exact timing is a decision for the family with their clinician and the care setting’s own policy. Bear in mind that RSV can still be shed for a while after recovery, so handwashing and keeping the baby from sharing pacifiers or cups remain sensible even once symptoms have faded.

Can bronchiolitis be prevented?

Risk can be reduced but not eliminated. Handwashing, keeping people with colds from kissing the baby, cleaning frequently touched surfaces, and a smoke-free home all lower exposure. The CDC also describes two options against severe RSV specifically: an immunization given during pregnancy that passes antibodies to the baby, and a long-acting monoclonal antibody given to eligible infants. Eligibility and timing depend on the individual child and are decided with the pediatric clinician.
