All it starts in 2002 when a new type of SARS-CoV virus were discovered. Then came a long period of calm and no one would expect what happen next and what it cause. At the end of 2019 in Wu-Chan. If all people wouldn‘t use any protective equpment (veil, desinfection and many others...). They can easily become infected. If they do, then they need to go in quarantine to save others from infection. If they‘r very infected they need medical assistence (breathing apparatus or something like that). There‘s also a risk group that has a higher risk of death or worsening these symptoms: fever, dry cough, tiredness, aches and pains, sore throat, headache etc... To risk group belongs: Cancer, chronic kidney disease, obesity, heart diseases and lot of these, of course people around 60/70 years old. As already mentioned, the pandemic began in Wu-Chan and later conquered the whole world. Our first infected people (Czech republic) appeared in 1.3.2020 and that started whole epidemic situation in our country. It was really big problem because no one don‘t lnow what to do at it was frustrating and also very psyche when you see what is happening in the world and everyone is talking about deaths and infections. Of course, it was important though, but I think that if they calmed down a bit and talked about something little different in the world, it would slow down the commotion. As no one knew was happening, government measures tightend rapidly and the world went mad. Nowadays (especially in our country) the deteriorating situation is so bad, that it is not know whether schools open until Christmas, probably not.
