According to CNN Health, a sniffle, a sneeze, or a cough can set off alarm bells these days for families with young children.

Many kids have spent years socially distancing to protect against Covid-19, and now health care systems are being overloaded with cases of the respiratory virus RSV — which can cause a runny nose, decreased appetite, coughing, sneezing, fever, and wheezing. 

The public health challenge this year is that while many children were kept home to protect against Covid-19, they were also isolated from RSV, meaning more are having their first — and therefore most severe — infection now, said CNN Medical Analyst Dr. Leana Wen, an emergency physician and professor of health policy and management at the George Washington University Milken Institute School of Public Health.

An RSV infection is often mild but could be a cause for concern for young infants, children with underlying conditions and older adults, said Schaffner, who is also medical director of the National Foundation for Infectious Diseases.

That doesn’t mean it is time to panic, added Wen, who is also author of “Lifelines: A Doctor’s Journey in the Fight for Public Health.” Catching RSV and other viral and bacterial infections is a part of children growing up and developing their immune system.

Here’s how to assess when to keep your child home from school and when to visit the pediatrician, according to experts.
