The name 'Coronavirus' comes from the Latin word 'corona'. In English it refers to something looking like a crown.
The appearance of the viruses is reminiscent of the sun's rays - it is also called a sun corona
In China, the virus has evolved in wild animals such as bats and snakes.
In Wuhan - a city in China – these wild animals were sold and eaten, which transferred the virus to humans.
From there, people flew on planes to many other countries around the world taking the virus with them.
If you have contracted the coronavirus, the viruses are also in your mouth.
If you then have to cough, tiny droplets of saliva fly out of your mouth. If you cough on your hand, the droplets on there will contain the virus.
These droplets can infect others! So, cough inside your bent arm, not into your hand!
Like most viruses, the coronavirus is transmitted primarily through the hands. So wash your hands regularly!
First wet your hands thoroughly, then squirt or use soap on them. Now rub well – even between your fingers.
Finally don‘t forget your nails, thumbs and wrists.
If you sing the song 'Happy Birthday' twice while washing your hands, you'll definitely be washing long enough.
The coronavirus spreads exponentially. This means that the number of people infected with the virus doubles in a certain period of time.
Let's take hamsters as an example. On the first day you bought two hamsters. After a day, there are four, so already twice as many.
A day later it is already twice as many as the previous day, so now you have eight hamsters and that goes on and on.
Write down how many hamsters there will be over the next few days.
If you go for a walk to the shops you must follow social distancing rules.
This means that we should stay so far away from other people that no virus can be transmitted.
The distance should be at least 2 meters or 6ft - about one shopping cart length when your arms are out stretched!
In order not to infect others or to be infected ourselves, we should all keep our distance from each other.
We should not get too close to other people now. Places where people usually get close, such as schools and playgrounds, are closed. We shouldn’t even visit our family and friends.
So that fewer people contract the corona virus in a short space of time, we should keep our distance from each other if possible. That's why many parents now work from home.
It is definitely very exciting - finally you can see what mum or dad are doing at work.
In order to prevent only a few people from meeting and being infected with the coronavirus, some countries, such as Great Britain, Spain or France, have adopted a 'lockdown'.
There, people are only allowed to work, to the supermarket or to the pharmacy. This means that the coronavirus can no longer spread as easily.
You may know of something similar for babies. Putting babies in playpens means that they are not allowed to go anywhere, but also means nothing can happen to hurt them.
The high risk group includes everyone for who infection with the coronavirus can lead to a serious illness.
These are mainly people over the age of 50. Children usually don't even notice when they get infected, but they can pass it on to their grandparents or other older people.
The older you are, the more dangerous the virus is. Therefore, younger people cannot visit the elderly for a while.
