When the pandemic hit us in 2020, we knew little about covid-19 and the virus that causes this brand new disease. Now we know a lot more. It has been shown that the coronavirus is almost exclusively transmitted through the air. If you don’t breathe in the virus, you won’t get infected. That is why many people notice covid as a cold and cough. But after the virus has entered through the respiratory tract, it spreads further to the whole body. What the coronavirus does to the body A virus consists almost exclusively of packaged genetic material. In order for the virus to reproduce, it must enter the body’s cells. The virus “infests” our cells to make many new copies of itself.
