RSV infections surge in Poland, posing risks to seniors and infants

Medical experts are warning of a significant rise in Respiratory Syncytial Virus (RSV) infections in Poland. Data from the Chief Sanitary Inspectorate indicates that in the first 14 weeks of 2026, there were 102,164 recorded cases, a sharp increase compared to previous periods.

While RSV is traditionally associated with infants, doctors emphasize that it poses a severe threat to adults over 60, particularly those with underlying heart or lung conditions, such as COPD or diabetes. Symptoms often mimic a common cold—including runny nose, sore throat, and cough—which can lead to delayed diagnosis. In seniors, the virus can cause dangerous drops in blood oxygen levels and exacerbate heart failure.

Regarding pediatric care, reports show that while nearly all children encounter the virus by age two, prophylaxis coverage in Poland remains low. Only 1.5% of infants are covered by current preventative measures, compared to 24 EU countries that have implemented passive prophylaxis using monoclonal antibodies like nirsevimab.
