Coronavirus are a type of virus which causes widespread colds, however can even cause more severe ailments comparable to SARS, MERS, or COVID – 19. The virus is only about 0.025 µm in diameter, far smaller than the human eye can see even with the very best optical microscope. Compared, a fine human hair is about 40 µm in diameter. When individuals talk, cough, or sneeze they eject small droplets which fluctuate greatly in measurement however the common is about 1 µm. Each small droplets can hold hundreds of 1000’s of viruses and the droplets can persist in the air for a number of hours.
This image of a coronavirus taken by an electron microscope shows small buildings on the surface which look like crowns. When the virus encounters a human cell, the crown attaches to the cell’s surface and injects its own RNA into the cell, which then takes over the cell mechanisms and produces copies of the virus. They finally cause the cell to burst which can launch as much as 50,000 new viruses.
COVID-19 Virus is a new virus in humans which entered the inhabitants for the first time late in 2019. The virus can not live lengthy outside a human host, and the principle vector for its transmission is those that travel to and from infected areas. Now we have little natural immunity to the virus and there’s no proven treatment or vaccine for the virus.

The virus is transmitted by direct contact between people from small droplets ejected when an infected person talks, coughs, or sneezes. The social distance of 6 ft is normally sufficient to stop the virus being transmitted directly. However, small droplets from coughs or sneezes could travel a lot additional than 6 feet and will comprise hundreds of thousands of viruses. The droplets might persist in the air for a number of hours. They ultimately settle on surfaces the place the virus could live for as much as a number of days, depending on the type of surface. For example, the virus is found to exist for a day on cardboard and as much as three days on tile or plastic.
