Question

How do viruses start

Answer 1

Answer:

They essentially first start with a small organism. This organism is then transferred to a host, usually transferred from eating/touching something. Then, the host gets infected with said virus.

The host will then pass on the organism by sneezing, coughing, and/or touching them. This continues on, usually until a cure is found. It can still have the ability to transfer, generally from people who don't get the cure.

Viruses can sometimes have a larger impact during different times.

Some people may also be more subject to the virus if they have vitamin deficiency or other health problems/issues.  

Answer 2

How It Starts: A small particle of bacteria gets infected with another particle of bacteria which causes the a new disease or virus animals or humans breathe in this air and spreads the virus.

If The Animal Gets It: The animal could potentially bite a human spreading the virus causing the human to spread it to other people.

If The Human Gets It: The human coughs, sneezes, or breathes on or near people causing the virus to spread.

Hope this helps!
