Coronavirus cause: Origin and how it spreads

COVID-19 is a modern coronavirus strain that causes disease. The letters CO, VI, and D stand for corona, virus, and disease, respectively. This disease was previously known as the '2019 novel coronavirus,' or '2019-nCoV.'

Coronaviruses are found in a variety of animals, including cattle and camels. While human-to-human transmission of coronaviruses is uncommon, According to Trusted Source, this new strain is thought to have originated in bats, but one study indicates pangolins might have been the source. However, it is still unknown how the virus first infected humans. According to some sources, the first cases were discovered in a Wuhan seafood and animal market. SARS-CoV-2 may have begun to spread to humans from this location.

When people with COVID-19 cough or exhale, tiny droplets containing the virus are expelled. These droplets may infect someone who does not have the virus by entering their mouth or nose.

Near contact with someone who has the infection is the most common way for this disease to spread. Close contact is described as being within 6 feet of each other. Source you can trust. When a person's symptoms are at their worst, the illness is most infectious. It is likely, however, for someone who is symptomless to transmit the virus. According to a recent survey, 10% of infections are caused by people who have no symptoms.

Virus-carrying droplets may also fall onto surrounding surfaces or structures. By touching these surfaces or things, other people may become infected with the virus. If the individual then touches their nose, eyes, or mouth, they are likely to become infected.

COVID-19 is a relatively new virus, and research is still ongoing. There may be additional avenues for the new coronavirus to propagate.
