Seasonal influenza is an acute respiratory tract infection caused by 4 distinct types of viruses- Influenza A, B, C and D belonging to the Orthomyxoviridae family. Among these types, Influenza A is the most common pathogen for humans.

Globally, influenza cases are typically seen to increase during certain months of the year. India usually witnesses two peaks of seasonal influenza one from January to March and another one in the post-monsoon season.

According to Union Health Ministry, the cases arising from seasonal influenza are expected to decline from March end. In most cases, the disease is self-limiting with symptoms of cough and cold, body ache and fever etc. and usually resolves within a week.

However, potentially high-risk groups such as infants, young children, pregnant women, elderly above the age of 65 years and people with comorbidities might experience more symptomatic illnesses, even requiring hospitalisation.

Disease transmission is mostly airborne from person to person, through large droplets generated by the act of coughing and sneezing.
