CDC Winter Outlook: COVID, Flu and RSV Peaks Expected Near Last Season’s Level

Winter is coming, and with it comes the annual question that worries families, schools, workplaces, and hospitals: how bad will this season of coughs, fevers, and breathing problems be? The Centers for Disease Control and Prevention, known as the CDC, has now shared its outlook for the 2026-2027 respiratory disease season, and the headline is reassuring in a cautious way. The combined peak of hospitalizations from COVID-19, flu, and RSV is expected to be within 20 percent of last season’s peak.

In plain language, that means the CDC does not expect this winter to be dramatically worse than last winter, and it also does not expect it to be dramatically better. It expects something broadly similar. The agency gives that forecast with low to moderate confidence, which is an honest way of saying that respiratory seasons are hard to predict exactly, and small changes in viruses or behavior can shift the peak up or down.

This is a season outlook, not a report that flu has already arrived in full force. It looks ahead to the whole winter, using early data, past seasons, and models of how these viruses tend to spread. It is different from a weekly update that says flu is rising in one region this week, even though both kinds of information are useful. The outlook helps hospitals plan beds and staffing, helps families think ahead, and helps everyone understand what kind of winter to prepare for.

Quick Facts

What Within 20 Percent Really Means

When the CDC says the combined peak could be within 20 percent of last season’s peak, it is giving a range, not a single number. If last season’s peak was 100 hospitalizations on the worst week, this season’s peak could be roughly 80 to 120 on its worst week, under that way of thinking. That is still a wide range, and it shows why the agency is careful about confidence.

Low to moderate confidence is not a weakness in the forecast. It is honesty about how many unknowns remain. A new variant, a colder than usual winter that keeps more people indoors, a change in vaccine uptake, or a school holiday pattern can all move the numbers. The CDC is saying: based on what we know now, a season similar to last year is the most reasonable expectation, but we could be off by a fair amount in either direction.

For families, the practical meaning is simple. Do not assume this winter will be easy just because last winter is over, and do not assume it will be a disaster either. Plan for a normal, busy respiratory season, with the usual steps that reduce risk, and stay flexible if local activity rises sharply.

Flu: A Moderately Severe Season Expected

Flu gets its own clear message in the outlook: a moderately severe season is expected across age groups. That wording matters. It does not say mild, and it does not say severe. Moderately severe means flu is expected to cause a meaningful amount of illness, doctor visits, and hospitalizations, similar to what many people remember from a typical bad flu winter, but not necessarily a record breaking one.

Across age groups means the CDC is not pointing to only older adults or only young children. Flu can hit children, working age adults, and older adults, though the risk of serious illness is higher for very young children, older adults, pregnant people, and people with certain health conditions. That is why flu guidance is usually broad: most people benefit from thinking about vaccination, and higher risk people benefit most from acting early.

Current data from the October 30 update fits with an early season picture. Flu activity was low nationally but increasing in many areas. That is a classic early season pattern. Activity starts low, then rises in pockets, then spreads more widely. Flu A was rising in the West, and San Francisco influenza A test positivity was reported at 19.2 percent, which is a sign that flu was already circulating more actively there than in many other places.

COVID-19: Similar or Lower, Unless Something Changes

For COVID-19, the outlook is a little more hopeful. A similar or lower peak than last year is likely, unless a new immune-evading variant emerges. None has been seen yet, according to the outlook. Immune-evading means a variant that is better at getting past immunity from past infection or vaccination. If such a variant appeared, it could cause more infections and a higher peak, which is why the CDC includes that warning.

Right now, the current data points in a calmer direction. COVID was declining nationally in the October 30 update. That does not mean COVID has gone away. It means that, at that point in late October, the national trend was down rather than up. COVID still circulates year round, with rises and falls that do not always follow the same winter pattern as flu, but winter indoor crowding can still help it spread.

RSV and Other Winter Viruses

RSV, short for respiratory syncytial virus, is expected to have a peak near last year’s peak. RSV is often talked about less than flu and COVID, but it can be serious, especially for infants, young children, and older adults. In babies, it can cause bronchiolitis, which is inflammation of the small airways in the lungs, and breathing trouble that needs hospital care. In older adults, it can worsen existing lung or heart problems.

Current RSV activity was low in most areas in the October 30 update. That is normal for late October in many places, with RSV often rising later in the fall and into winter. Low now does not mean low all winter. The outlook expects RSV to rise to roughly last year’s level at its peak, so families with infants or older relatives should not be surprised if RSV becomes a bigger topic in the coming weeks.

That overlap is why the combined peak idea is so useful. Winter illness is rarely just one virus. It is a mix, rising and falling at slightly different times, and the strain on families and hospitals comes from the total, not from one virus alone.

Remembering Last Season in Numbers

Last season, 2025-26, gives a concrete sense of what a similar season could look like. According to CDC preliminary estimates, there were at least 32 million illnesses, about 390,000 hospitalizations, and 24,000 deaths linked to respiratory illness in that season. Those numbers are estimates, not exact counts, because many mild illnesses are never tested or reported, and hospital records need careful review.

Even as estimates, they show the scale. Thirty two million illnesses means tens of millions of people missed work or school, needed care at home, or visited a doctor. Three hundred ninety thousand hospitalizations means hospitals were busy for weeks. Twenty four thousand deaths is a reminder that these are not just colds for everyone. For most healthy adults, flu or COVID may mean a miserable week at home. For others, it can mean a hospital stay or worse.

That is why local data still matters, even with a national outlook. Checking your state or county health department updates, watching school and workplace absences, and paying attention to your own symptoms will tell you more about your immediate risk than a national forecast alone.

How to Prepare Without Panicking

Preparation for a moderately severe flu season and a near last year combined peak does not require panic buying or major life changes. It requires the same practical steps that health agencies repeat every year because they work, even if they sound boring.

First, think about vaccines early, and talk to your own doctor about which vaccines are recommended for you. Flu, COVID, and RSV vaccines have different recommendations by age and risk group, and guidance can change, so a quick conversation with your doctor or pharmacist is more reliable than guessing from headlines. Vaccines do not prevent every infection, but they reduce the risk of severe illness and hospitalization, which is exactly what the peak forecast is about.

FAQs

What does the CDC expect for this winter overall?

The CDC expects the combined peak hospitalizations from COVID-19, flu, and RSV to be within 20 percent of last season’s peak, with low to moderate confidence. That points to a winter broadly similar to last year, not dramatically better or worse.

Is flu expected to be bad this year?

Flu is expected to be moderately severe across age groups. Current data from October 30 showed flu activity low nationally but increasing in many areas, with flu A rising in the West and San Francisco influenza A test positivity reported at 19.2 percent.

What about COVID-19 and RSV?

COVID-19 is expected to have a similar or lower peak than last year, unless a new immune-evading variant emerges, and none has been seen yet. RSV is expected to peak near last year’s level. COVID was declining nationally and RSV was low in most areas in the October 30 update.

Should I get vaccinated or see a doctor?

This article is general information only and cannot replace personal medical advice. Please talk to your own doctor about vaccines, testing, and treatment for you and your family, especially if you are older, pregnant, have a chronic condition, or care for an infant.

Final Thoughts

The CDC winter outlook is best read as a steady warning, not an alarm. A combined peak near last year’s level, a moderately severe flu season, a similar or lower COVID peak, and an RSV peak near last year’s all point to a busy winter ahead, but not an unprecedented one. The numbers from last season, at least 32 million illnesses, about 390,000 hospitalizations, and 24,000 deaths, show why even a normal winter deserves preparation.

The most useful response is calm and early: talk to your own doctor, think about vaccines, make a sick plan, and watch local trends as winter progresses. If a new variant appears or local activity jumps, guidance may change, and the CDC outlook will be updated. For now, expect a winter much like the last one, and get ready for it in the same practical way you would for any busy cold and flu season.
