As the weather begins to warm and spring approaches, many families assume flu season is winding down. Unfortunately, influenza activity often continues well into March, and sometimes even into May. The perception that flu is “over” can lead to lowered guard, delayed care, and missed prevention opportunities.
For families, especially those with young children, understanding the risks of late-season flu is critical.
Flu Season Doesn’t Follow the Calendar
While flu activity often peaks between December and February, the virus continues circulating in communities for months afterward. According to the CDC, significant flu activity frequently persists through early spring.
Late-season flu can be just as severe as early-season illness. In fact, some years see a second wave of cases driven by a different influenza strain than the one that circulated earlier in the winter.
Just because classmates seem healthier or winter holidays have passed does not mean the threat is gone.
Why Late-Season Flu Can Be Especially Dangerous
By March, many families have relaxed precautions. Hand hygiene may slip. Gatherings increase. Travel ramps up for spring break. People who delayed vaccination may assume it’s too late.
This combination creates an environment where influenza can spread quickly.
In addition:
- Some children who avoided the flu earlier in the season remain unprotected.
- Immunity from earlier infection may not protect against a different circulating strain.
- Healthcare fatigue can delay parents from seeking prompt medical care.
Flu can still lead to severe complications, including pneumonia, dehydration, worsening of chronic conditions, and in rare but tragic cases, sepsis or death.
It’s Not Too Late for Protection
If flu viruses are still circulating, vaccination can still provide protection. Flu vaccines reduce the risk of severe illness, hospitalization, and complications — even if administered later in the season. Ask your healthcare provider or pharmacist about availability.
Preventive measures remain important:
- Frequent handwashing
- Covering coughs and sneezes
- Keeping sick children home
- Cleaning commonly touched surfaces
- Getting tested when showing symptoms
Staying vigilant through the entire flu season helps protect not just your family, but your community.
