Mode of Transmission
COVID-19 is transmitted via bodily fluids or respiratory droplets or spray through breathing, coughing, or even just talking.
Evidence has shown that the virus can survive outside of the body from several hours to several days, which means it may spread to people who are not in direct contact with an infected person. Studies have shown that the COVID-19 virus can survive for up to 72 hours (three days) on plastic and stainless steel, less than four hours on copper, and less than 24 hours on cardboard.
From the evidence so far, the COVID-19 virus can be transmitted in all geographic areas and climates, including those with hot and humid weather and those with cold weather.
People can be infected with the COVID-19 virus but fail to show signs and symptoms and are known as people with asymptomatic infection. This group of people poses a great risk of spreading the virus without knowing it. Others, however, may exhibit the symptoms of COVID-19 disease to different degrees (mild or severe), and they are known as symptomatic cases.
The risk of transmission is high from being in close proximity with persons whose status is unknown or who have an infection (less than 6 feet or 2 meters), as is the risk of touching potentially contaminated surfaces.
