How does COVID-19 spread?

Posted on March 20, 2020

You may have tons of questions about the novel coronavirus and one of these questions will definitely be about understanding how this virus spreads.

To understand this you will first have to know about some basics of this virus. The novel coronavirus is SARS-CoV-2 which is its clinical name. This is an acute respiratory syndrome coronavirus 2. The origin of this virus traces to a family of other viruses that are responsible to cause respiratory issues and respiratory syndrome.

The novel coronavirus is a new strain. This means that the virus is not familiar with the human immune system. This also means that there is still no vaccine for this virus.

When a person comes in contact with the coronavirus then he is diseased with the virus COVID-19. The virus is respiratory. It means that respiratory droplets are the carrier of this virus.

Here is how the novel coronavirus gets spread from one person to another. You should also take care to understand the protection methods from this new virus strain.


How does coronavirus spread from one to another?

The main transmission method of this virus is the person to person contact. Imagine that you are sitting close to a person who is already infected with this virus. The infected person sneezes or coughs and you catch the virus. If the infected does not cover his nose and mouth then they can immediately spread it to you. If the droplets land on you then you get infected with the virus.

You can also contact the virus when someone who already has the virus touches his or her mouth or nose with his hand. When you shake hands with this person then they transfer the virus to you. Once you touch your nose or your mouth without washing your hand you give the virus entry into your body and thus you are now infected too.

There is also a study to understand if coronavirus spreads through feces. It may contaminate the bathroom and the toilet bowls. Further research, however, is needed to understand this method of transmission.


Spreading the virus without any symptoms 

WHO states that if one does not show symptoms of coronavirus then his chances of spreading it to others are very low. But here there is some bad news. Experts are countering the views of WHO and say that there have been cases where one who did not show any symptoms of coronavirus passed it to others. The carrier was not even aware of the fact that he was sick.

A person is most contagious when he is showing symptoms of the virus and this is when they are more likely to transmit the virus. However, there could be some who may transmit the virus even before they show any symptoms. It could take 2 days to 14 days to show up the symptoms of coronavirus after one has been exposed to the virus.

Though there is still no cure for this virus, proper sanitization and hygiene methods should be followed to stay safe.
