About Magic of viruses Course

Viruses are some of the smallest microbes there are, way smaller than bacteria. You cannot see them with an ordinary microscope like bacteria; you need to use a very special microscope to see viruses properly. Viruses are so basic that they are not even cells, just genetic material (genes) wrapped up inside a strong ‘coat’ made of protein. They cannot survive by themselves, viruses have to use a host to grow and multiply which makes them a type of parasite.

Some viruses are very clever. They don’t die off if they don’t have a host, they just hibernate (they become dormant) and wait for the right conditions to come along so they can make copies of themselves. Viruses can spread very easily from one person to the next just by touch or by sneezing or coughing when they fly out into the air in tiny water droplets. If a person doesn’t cover their mouth and nose when they sneeze or cough, you could breathe in their virus! Other viruses are spread when people are lazy about personal hygiene and they don’t wash their hands very often, especially when they have been to the toilet. Viruses also wait in areas you wouldn’t expect them to like door-handles or telephones so you should make sure to clean up after you and that you wash your hands regularly!

There are several thousand different types of viruses which use plants animals or even you as a host! Once a virus gets inside its host, it uses the hosts own cells to grow and make copies of itself. When a virus gets into your body and sees a cell it likes, it latches on and either injects its genes into your cell or your cell swallows it up. The virus then takes over the parts that make your cell work so it can make more copies of itself. These copies are identical to the first virus and usually, so many are made that your cell bursts! The new viruses spread to the cells next door and then the cells next to these, infecting your body bit by bit. Just one virus in your body can make thousands of copies of itself and make you very sick!
