Some secret about virus
Influenza A virus subtype H3N2 is a strain of the influenza A virus that causes seasonal flu in humans.
It is one of the two main types of influenza A viruses that cause human flu, with the other being H1N1.
H3N2 was first identified in humans in 1968 & has been a circulating strain of seasonal flu ever since.
H3N2 is a highly contagious virus that spreads from person to person through respiratory droplets when an infected person coughs or sneezes.
Symptoms of H3N2 infection are similar to other strains of flu & can include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills, & fatigue.
In some cases, H3N2 infections can lead to more severe illness, particularly in people who are elderly, very young, or have underlying health conditions.
Each year, the World Health Organization (WHO) monitors circulating influenza viruses & recommends the strains that should be included in the seasonal flu vaccine.
The vaccine is updated annually to provide protection against the most common strains of flu viruses, including H3N2.
It is recommended that everyone over the age of 6 months receive the flu vaccine each year to protect themselves & others from getting sick.
