Today I want to cover 7 sneaky viral strategies. Viruses are very devious. They are much smaller than bacteria. Viruses are not really alive, but they also aren’t dead.

A virus is like a small sack that has a genetic copy machine, and it has the ability to copy itself over and over. But, it can only do that if it invades your cells. It leeches on to the cell, sucks the life out of it, and replicates. However, certain cells, like your red blood cells, don’t have DNA, so the virus can’t leech on to them.

Once they start to replicate, they begin to create a lot of damage within the immune system. The immune system sees this foreign invader and creates a lot of inflammation and more collateral damage.

7 sneaky viral strategies:

1. Viruses can infect your B and T cells
2. Viruses can infect your monocytes
3. Viruses can infect your thymus
4. Viruses can escape the antibody response
5. 2 viruses can invade one cell and escape the attack from the immune system
6. Viruses can escape cytokines
7. Certain viruses can downgrade vitamin D receptors
