The new Coronavirus SARS-CoV-2 has overturned our daily lifestyle and our entire standard analysis. Is walking on the road safe? What about our shopping in a supermarket with 1-meter separation? Furthermore, should not something be said about talking with an unknown person? Also, which of these exercise represents the most significant hazard?
Sadly, there's a lot of things about COVID-19, we still don't know. At this point, over the long period, as time goes on, we are finding out unknown features of this new virus. That is what we do think about how the new coronavirus, SARS-CoV-2, spreads over the world.
Corona Virus
There are several transmission paths followed by SARS-CoV-2 are explained below -
1. Respiratory Transmission :
While SARS-CoV-2 has not overturned the fundamental frameworks of malady transmission, few subtleties could assume a significant job in the spread of the new coronavirus disease COVID-19. Centers for Disease Control and Prevention ( CDC) has said that SARS-CoV-2 is a respiratory infection. For that capacity, it is mostly transmitted between individuals through " respiratory beads " when infected individuals cough or sneeze. In this way, large beads of the virus are transmitted from a sick body to a healthy body. The CDC's recommendation is to keep up the separation of 6-foot distance (i.e., 2 meters) between individuals. The reasoning is that earth gravity causes those large beads ( > 5 microns, in size ) to tumble to the ground. Therefore, the chances of transmission of the SARS-CoV-2 virus increase when people make contact with each other within a 2-meter distance. Yet, that 6-foot rule is all the more a rough approximation than an immovable principle.
2. Surface Transmission :
There's also another route of transmission of the SARS-CoV-2 virus, which plays a vital role in the spread of COVID-19. That is the surface transmission. In this transmission, the virus launched on an environmental surface from the infected respiratory tract. When an uninfected person touches that surface, followed by touching his nose, mouth, and eyes, the virus then enters into the body via nose or mouth and places on the respiratory organs.
One research study found out that the SARS-CoV-2 virus could remain alive on a few surfaces such as plastic and steel for 2 to 3 days and the cardboard for up to 1 day. Therefore, within this alive period, if people come in contact with those surfaces, there will be a chance of infection by SARS-CoV-2.
3. Airborne Transmission :
Airborne Transmission is somehow different from the above-explained transmission path. Because it directs the availability of germ within droplets, which are normally less than 5 micrometers in diameter and can stay in the air over significant time and can be entered into individuals' bodies by breathing even if they maintain a distance greater than 1 meter. A research study published on March 17 in the New England Journal of Medicine stated that aerosolized microbes could remain alive in air for up to 3 hours.
