What is this new H3N2 Flu ?






What is H3N2?

H3N2 is a subtype of the Influenza A virus, which can cause seasonal flu in humans. It was first identified in the late 1960s and has since caused numerous outbreaks around the world. It is While some symptoms of Covid-19 and H3N2 are the same, the incubation period for the H3N2 virus may be much shorter than that of Covid-19.


How long does the infection last?

The infection caused due to the H3N2 virus lasts five to seven days and the fever starts going away after three days. However, the coughing can persist for up to three weeks.


What are the symptoms?

H3N2 flu is typically characterized by symptoms such as fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, and fatigue. In severe cases, it can lead to pneumonia, needing hospitalization, and rarely even death, particularly in vulnerable populations such as the elderly, and those with weakened immune systems.


Is there any treatment for the flu?

The flu does not need any specific treatment as it is mostly self containing. Symptomatic medicines for fever, cold and cough are given. Antibiotics are not effective and not recommended.


Are vaccines available?

The H3N2 virus is known for its ability to mutate rapidly, which makes it difficult for vaccines to provide complete protection against it. Therefore, flu vaccination is recommended each year to help reduce the severity of illness and prevent transmission of the virus. However, the Advisory Committee on Vaccines and Immunization Practices have said that the influenza vaccine in India has not been recommended for Universal Immunization Programme (UIP) yet.

Flu is mostly a seasonal virus and the spread should subside as the temperatures rise in summer.
