According to the Centers for Disease Control and Prevention (CDC), COVID-19 is primarily spread through respiratory droplets when an infected person coughs, sneezes, talks, or breathes. These droplets can then be inhaled by people nearby or land on surfaces, where they can survive for varying lengths of time. It is also possible to contract the virus by touching a contaminated surface and then touching your face, although this is thought to be a less common mode of transmission.It is important to note that the virus can also be spread by individuals who are asymptomatic or pre-symptomatic, meaning they do not display any symptoms or have not yet developed symptoms. This makes it crucial to practice preventive measures, such as wearing masks, practicing social distancing, and washing hands frequently, to reduce the risk of transmission.It is also worth mentioning that there is still ongoing research and investigation into the various modes of transmission of COVID-19, and the information provided is based on current understanding.
