These studies identify and test all contacts of known positive COVID-19 cases to determine the proportion that go on to become infected.
And while it's difficult to pinpoint precisely where and when someone caught an infection, pooling this contact tracing data together allows us to gain insights into the settings that are potentially higher risk for onwards transmission.
They identify a known case and trace all their contacts.
Once they've found their contacts, they then test all of these contacts to know the proportion that go on to become infected.
And they test them at multiple time points for around up to 14 days.
We found that prolonged household contact and social contacts with family and friends had the highest risk for onwards transmission compared to other settings such as travel or healthcare or casual close contacts.
