Covid 19

​

​

 

 

Viruses such as the corona virus SARS-CoV-2 are not visible to the naked eye and are only about 20 to 300 nanometers in size. They invade animal, plant or human cells and use these living cells as so-called host cells. Even when exposed to air, they can sometimes survive for a very long time and remain contagious. However, a new host cell is necessary for long-term survival - if they do not find it, viruses die sooner or later.

Not all viruses cause disease. Our immune system often reacts quickly and fights off intruders immediately. Viruses begin to multiply in the body as soon as infection has occurred. Drugs are of limited help against viruses and antibiotics have been proven to be ineffective against viral diseases. There are antiviral drugs that only help against certain types of viruses. Since viruses (for example the influenza virus) can change, they are able to get past the body's own defenses more easily. A person only becomes immune when his body has dealt with the pathogen. However, even after a disease has been overcome, immunity is not always guaranteed. Viruses do not have their own metabolism.

 

How is the Coronavirus SARS-CoV-2 transmitted?


According to current knowledge, the corona pathogen SARS-CoV-2 is primarily transmitted via droplets. This involves people coughing or sneezing and distributing the pathogens in the air. Other people inhale these pathogens and, in the worst case, become infected.

 

Indirect infection:

 

Indirect transmission of the virus is also possible. People who have previously coughed or sneezed into their hands touch objects such as door handles, mobile phones, touch screens or chair backs. The viruses remain on the surface and reach healthy people from there.

 

Contact infection:

 

Contact infection is also a way for viral diseases to spread. For example, even the smallest, contaminated residual traces of human stool can reach a healthy person via dirty hands. Infection is also possible if the pathogen enters the body directly via the mucous membranes of the eyes, throat and nose or the upper airways, for example through a kiss. It has not yet been finally clarified whether SARS-CoV-2 spreads via contact infection. One of the most effective measures to prevent contact infection is to wash your hands thoroughly with soap.
