Ziro’s explanations were interesting. It turns out that viruses are

microbes thatcan only be seen under a powerful microscope.

There are many microbes that aren’t harmful to us, such as the

bacteria used to produce yogurt and the fungus we use to make

Roquefort cheese. But microbes also include viruses, and some

of them cause colds and flu.

The viruses reach our body...

They often travel in the

droplets we expel when we

cough, sneeze, or even when

we talk!

And then they infect us. That’s

what makes us sick. And we

don’t recover until our body

reacts and zaps the virus!

So what’s the

problem then?
