As many countries emerge from lockdowns, researchers are poised to use genome sequencing to avoid an expected second wave of COVID-19 infections.

Since the first whole-genome sequence of the new coronavirus, SARS-CoV-2, was shared online on 11 January, scientists have sequenced and shared some 32,000 viral genomes from around the world. Such a vast amount of data has allowed researchers to trace the origin of COVID-19 outbreaks in their countries and pinpoint when community transmission occurred2.

Now, countries that have successfully suppressed infections are entering the next phase of the COVID-19 pandemic — where there's a risk of new cases appearing as social restrictions ease. Researchers say that genomics will be crucial to quickly track and control these outbreaks. Studies already show that outbreaks tend to be shorter and smaller when genomics is used to help contact tracing1.
