How does the Influenza A subtype H3N2 virus spread and infect our body?

Why the flu keeps coming back every year? 

It's because the influenza virus is constantly mutating, making it difficult for our immune system to fight it off. In today's video, we're going to talk about one specific strain of the flu virus - Influenza A subtype H3N2. 

So, how does this virus transmit and cause infection in the host body? 

Well, the H3N2 virus spreads through respiratory droplets when an infected person sneezes or coughs. These droplets can land on surfaces or be inhaled by someone nearby, leading to infection. The virus then enters the body through the nose, mouth, or eyes, and begins to replicate in the respiratory tract. 

When the H3N2 virus enters the body, it attaches itself to specific cells in the respiratory tract. These cells are like the virus's key to getting inside the body. Once inside, the virus hijacks the cell's machinery to make more copies of itself. These copies are like little virus soldiers that can attack other cells in the respiratory tract. When the virus soldiers invade more and more cells, the respiratory tract becomes inflamed and irritated, causing symptoms like fever, cough, and body aches.. 

How can you protect yourself from H3N2? 

The best way is by getting vaccinated every year. The flu vaccine contains a dead or weakened version of the virus, which stimulates the immune system to create antibodies against it. These antibodies can then recognize and fight off the live virus if you're exposed to it in the future. 

Understanding how the Influenza A subtype H3N2 virus spreads and infects our body can empower us to take better care of ourselves during flu season. By getting vaccinated, practicing good hygiene, and staying informed about the latest developments in the fight against the flu, we can protect ourselves and those around us from this constantly mutating virus. So let's take charge of our health and stay healthy! Thanks for watching. -
