How does the flu reproduce?
Influenza viruses reproduce inside the cells of their host. The virus enters the cell and uses the cell's machinery to make copies of itself. The new viruses are then released from the cell and can infect other cells.
The flu virus has a unique way of reproducing that allows it to change quickly. This is why there are new strains of the flu virus every year. The virus changes so that it can evade the immune system of its host. This is why it is important to get a flu shot every year, so that your immune system can be prepared for the latest strain of the flu.
Here is a more detailed look at the steps of flu virus reproduction:
* Attachment: The virus attaches to a cell on the surface of the host's respiratory tract.
* Entry: The virus enters the cell.
* Replication: The virus uses the cell's machinery to make copies of itself.
* Assembly: The new viruses are assembled.
* Release: The new viruses are released from the cell.
The flu virus can spread from person to person through close contact, such as coughing or sneezing. It can also be spread through contact with contaminated objects, such as doorknobs or countertops.
