The virus has very high spread and can be transmitted through aerosol spread thus speaking, coughing, sneezing, etc can spread it very quickly. It’s also quite a slow acting virus and can take over two weeks to show symptoms making it even easier to spread as the carrier doesn’t know they have it until it’s sort of already too late. Usually when viruses get like this the most effective way to eradicate them is to develop effective treatment and vaccination. Treatment helps to stop the effects of the virus and allow the body to fight it off and vaccines help prevent the virus as well as allow the body to develop certain levels of immunity to the point where if an individual does catch the virus they are able to fight it off more effectively and with decreased risk of mortality or long term and permanent side effects of the virus.
