Virus Structure Image

  • Insects, such as mosquitoes, can spread viruses from person to person or animal to animal.
  • When a virus attacks your body, your body remembers it. The next time it invades, your body is ready to fight it off. Some viruses, though, like the flu, can change so you can get sick more than once. Pretty sneaky trick, huh?
  • Sometimes viruses that normally infect animals can jump to humans.

Virus Q&A

Question: Can antibiotics kill a virus?

Answer: Antibiotics kill bacteria, not viruses. When a virus enters your body, it hijacks a cell and begins reproducing. The cell explodes and the virus cells move on to infect other cells in your body. Vaccines and anti-viral drugs can fight viruses. Your own body is made to fight off viruses too.
