Contact tracing is a very common public health tool. It’s important for stopping the spread of COVID-19.
But it’s used every day by public health to protect the health of the public.
Contact tracing protects the health of people, because if we can limit contact between infectious people and others, we can limit opportunities for SARS-CoV-2 to be transmitted. So it’s really important to keep in mind here that the whole case investigation and contact tracing effort is being done to protect the health of the public.
Contact tracing is used every day to stop disease transmission. It’s used for tuberculosis, syphilis, which is a sexually transmitted disease, HIV, and you may recall a large outbreak of Ebola in West Africa.
Contact tracing was a key part of the strategy to end that outbreak. You can see here that contact tracing in that scenario was done even by boat. Much of the contact tracing was done in person. So there are many different ways that contact tracing is done. But it’s important to remember this is a common tool. It’s used every day.
And it’s going to be used also to help stop the COVID-19 pandemic.
