(LEX 18) — A new study suggests that quick testing is needed in order for contact tracing to be successful.

Researchers used a mathematical model that helped them predict how delays in testing impacts the spread of the virus.

They found that if testing is delayed by at least three days after the onset of symptoms, then contact tracing will not be able to stop the spread.

They say that in order for contact tracing to work, test results need to be delivered within a day of a person developing symptoms.

The scientists also say that mobile apps could also help with contact tracing by alerting people who have been in close contact with an infected person.
