Controlling the next phase of the 2020 coronavirus outbreak is likely to depend on contact tracing – tracking down anyone who has been in contact with a person showing symptoms of the virus.
It will involve tracing anyone who has come into close contact with someone who has tested positive and advising them to self-isolate to stop further spread.
There are lessons to be learned from one of the last big contact-tracing exercises – carried out almost 60 years ago during the smallpox outbreak of 1962.
