Q.

Virus/Bacteria

Hi Professor,

What is the difference between a virus and a bacteria, in a nutshell? Are they both contagious? Can they both be treated by anti-biotics.

Thank you.

Both of these organisms are very small and cannot bevseen by the naked eye, but viruses are even smaller than bacteria.Viruses have to enter body cels to survive and multiply. Bacteria are usually killed by antibiotics but not viruses. Some viruses can now be treated by anti-viral medicines.

Bacteria is living and can be killed with antibiotics.
You get good bacteria in your gut which helps with digestion and so on. Bacteria is used for making yoghurt.
If you cut yourself and it goes sepstic, that is a bacterial infection. You can get a runny stomach from bacteria if you don''t wash your hands after going to the toilet or before eating. You can get food poisining from bacteria in food. One form of meningitis is also bacterial.

A virus is non living and so can''t be killed with antibiotics.
Colds, flu, measles, chicken pox and so on are viruses. Some are spread in the air, some are spread by someone rubbing their nose or eyes and touching a door handle that we touch and we then put our hand near our nose or mouth - which is why its a good idea to wash your hands regularly.
