Spreading Pattern of Corona Virus
There is one thing which one needs to understand on how the virus spread: When a sick person coughs Infront of a healthy person, then the saliva drops coming out of the person's mouth get in contact with the eyes, nose or mouth of the healthy person, which causes the transfer of the coronavirus.
So, if you see someone who is visibly coughing, sneezing or is sick, then you should stand at a safe distance of 0.5m to 2m to protect you from the large droplets. Alternatively, you can give the sick person a mask to cover their mouth when they sneeze or cough, to protect other people who are standing nearby(Ai, Y. et al., 2018) and (Acharya, P. et al.,2001) and (Thakur, G. et al.,2014).
In general, it is a good idea to avoid crowds because you do not know who might be sick. People who are infected can show no symptoms of the virus, and so precaution is better(Tyagi, S. et al.,2020).
However, sometimes a sick person’s saliva can get on other things such as pen, mouse, their hands, tissues, digital equipment’s like mobile, stair bannisters, etc. Even the outside of the mask of a healthy person can get the saliva of the sick person. Moreover, when one touches any of these things, then, later on, touches their face, eyes or their loved ones then they will get sick as well the people they are meeting will get the virus. Viruses can last for 48hrs on any object. So, the only way to get rid of them is by washing these objects with soap(Acharya, P. et al.,2001) and (Acharya, D. et al.,2016) and (Nair, R. et al.,2017).
