Health officials have sounded the alarm over a sharp increase in Influenza A and B infections across Sri Lanka, with children among the most severely affected.

Dr. Maheshaka Wijayawardena, Consultant Paediatrician, told the media that seasonal flu outbreaks are particularly active during the rainy months and toward the end of the year. Children in daycares, pre-schools, and schools are especially vulnerable.

“The illness can present in various ways,” Dr. Wijayawardena explained. “Many children develop sudden fever, cough, sore throat, runny nose, and fatigue, while some experience cold-like symptoms, ear infections, sinusitis, or wheezing—particularly those with asthma. Young children may also suffer vomiting and diarrhoea, sometimes leading to dehydration. In rare cases, influenza can affect the nervous system, and infants under two years or children with chronic illnesses face a higher risk of pneumonia and severe respiratory complications.”

He urged parents to closely monitor their children for symptoms and seek immediate medical care if signs of severe illness appear, including rapid or difficult breathing, persistent vomiting, loss of appetite, or unusual drowsiness.

Preventive measures such as frequent handwashing, covering coughs, and keeping sick children at home until fully recovered are essential to limiting the spread. Vaccination is recommended for high-risk children.

“Most children recover with simple care at home,” Dr. Wijayawardena said, “but early medical attention is crucial for those with warning signs or underlying conditions. Vigilance and preventive practices are the best protection against complications during this outbreak.”
