Gene sleuths are tracking the coronavirus outbreak as it happens Genetic data shows that countries are getting hit with multiple introductions of the virus
By tracking mutations to the virus as it spreads, scientists are creating a family tree in nearly real time, which they say can help pinpoint how the infection is hopping between countries.
When scientists in Brazil confirmed that country's first case of coronavirus late in February, they were quick to sequence the germ's genetic code and compare it with over 150 sequences already posted online, many from China.
The patient, a 61-year-old from Sao Paulo, had traveled in Italy's northern Lombardy region that month, so Italy was likely where he acquired the infection. But the sequence of his virus suggested a more complex story, linking his illness back to a sick passenger from China and an outbreak in Germany.
