Based on their genomic sequencing analysis, Andersen and his team concluded the possibility of origin of SARS-CoV-2 following one of two possible scenarios.
The first scenario, namely the virus evolves in the current pathogenic state through natural selection in non-human hosts, then jumps to humans. Example: Corona virus in bats. Whereas in other scenarios, non-pathogenic versions of the virus jump from the animal host to humans, then evolve into pathogenic conditions in the human population. Example: Corona virus in pangolins.
The transmission of the disease can spread through small droplets from the nose or mouth when someone infected with this virus sneezes or coughs. So how we can know if we got this disease or not?. WHO (World Health Organization) added the most common symptoms of COVID-19 are fever, fatigue, and dry cough. Some patients may experience aches and pains, nasal congestion, runny nose, sore throat or diarrhea. These symptoms are mild and occur gradually. Therefore let's prevent this disease in a way in between :
1. Wash your hands as often as possible, do it with 7 steps correctly (Why? Wash your hands with soap and water or use alcohol-based hand rubs to kill viruses that may be in your hands).
2. Maintain a minimum social distance of 1-2 m (Why? When someone coughs or sneezes, they spray small drops of liquid from their nose or mouth that may contain viruses. If you get too close, you can breathe in water droplets, including the COVID-19 virus if the person has a cough).
3. Avoid touching the eyes and nose (Why? Hands touch many surfaces and can pick up viruses. After being contaminated, hands can transfer viruses to your eyes, nose, or mouth. From there, viruses can enter your body and can make you sick).
4. Use mask of your sick.
5. Eat nutritious foods.
6. Always exercise, to maintain stamina.
And what's we gonna do if we got that disease?
First, don't panic, Always think positive that you will recover
Secondly, immediately contact the nearest medical personnel to get further action
Third, follow the medical procedures applied
