Viral transmission and spread 
of disease

The SARS-CoV-2 virus can be transmitted between people when they cough, sneeze, talk, or breathe. The infectious respiratory particles (droplets or aerosol) contain the virus and can either be transmitted directly to another person, or indirectly through droplets on surfaces. The viral particles can enter the nose, mouth, or the eyes, infecting the body and causing disease.1

There are many factors that can affect SARS-CoV-2 transmission between individuals and within populations, from the communicability of each new variant, to social behaviours within communities.1,2

By studying these individual and population factors, we are building a clearer picture of how COVID-19 spreads, helping us to create interventions that may help to reduce infections and save lives.1

Transmission between adults and children 

SARS-CoV-2 transmission in multigenerational households plays an important role in spread of the disease.
