Specific COVID Information

What is the mode of transmission?


The main route of transmission is from cough and sneeze droplets. These droplets fall on people or surfaces in the vicinity and can be directly inhaled or picked up on the hands and transferred when someone touches their face.



Does it stay on surfaces?


Depends on a number of factors:


•what surface the virus is on
•whether it is exposed to sunlight
•differences in temperature and humidity
•exposure to cleaning products


Under most circumstances, the amount of infectious virus on any contaminated surfaces is likely to have decreased significantly by 24 hours, and even more so by 48 hours. Contaminated waste left for 72 hours to make sure.



What is the incubation period?


The incubation period (i.e. time between exposure to the virus and developing symptoms) is between 1 and 14 days (median 5 days).



When is a person infectious?


A person is thought to be infectious 48 hours (two days) before symptoms appear, and up to  10 days after they start displaying symptoms.
