Explanation: A bacteria and virus is EXTREMELY different, we all have bacterias in our body's even right now, to much of it can make somewhat a virus. Now , you have to understand that a virus spreads, it can be through food, a person or living thing, or just by smelling or touching something, a virus is like a person itself, it needs a body to live in or else it will die out. Lets consider its just bacteria that is entering you're body right now, there is so much bacteria that is beats up the immune system, infecting it, this now makes a virus. When the virus gets past your immune system, it aims for the cells, it grabs on to a cell and starts multiplying at rapid speads making it spread, now, there can be symptoms of a virus or not, because, you may not feel the virus since it hasnt multiplied that much and has not actually infected to much. Once it does, you're bodys defense mechanism starts to step in, including, immune system and white blood cells, they do most of the job of clearing out the virus, but what about on the outside you may ask, well, you know when you're cold you start to shiver? That is your body trying to stay warm, or when you go out on a run and sweat? That is your body taking out heat, so just with the virus, you can get shivers, because your body is defending itself against it. The virus will eventually go away with the right treatment, as simple as a flu shot. I cannot assume that every virus is this way because the virus goes for different body parts, either the lungs (corona virus) , the brain cells, head, neurons or cells. But just keep in mind, that the virus multiplies, thats why it grabs on to the cell, so it can infect it and multiply. This happens in seconds! That is why you need to eat healthy and wash YOUR HANDS. Stay safe
Cheers!!
