Union Health Ministry is keeping a close watch on the Seasonal Influenza situation in various States/UTs through the Integrated Disease Surveillance Programme (IDSP) network on real-time basis. The Ministry is also tracking and keeping a close watch on morbidity and mortality due to the H3N2 subtype of the seasonal Influenza. Young children and old age persons with co-morbidities are the most vulnerable groups in context of seasonal influenza. So far, Karnataka and Haryana have confirmed one death each from H3N2 influenza.
Seasonal influenza is an acute respiratory infection caused by influenza viruses which circulate in all parts of the world, and the cases are seen to increase during certain months globally. India every year witnesses two peaks of seasonal influenza: one from Jan to March and other in post monsoon season. The cases arising from seasonal influenza are expected to decline from March end. State surveillance officers are therefore fully geared to meet this public health challenge.
A near real time surveillance of cases of Influenza like Illness (ILI) and Severe Acute Respiratory Infections (SARI) presenting in OPDs and IPDs of health facilities is undertaken by Integrated Disease Surveillance Programme (IDSP), National Centre for Disease Control (NCDC).
