Berlin (dpa / bb) - A second mutation of the coronavirus has been detected in Berlin's Vivantes clinics.
She is known with the name B.1.351 from South Africa.
Both cases were entered into the hospital from outside, the company announced on Friday.
It is a patient in the Vivantes Humboldt Clinic - not in connection with a trip.
A second patient at the Vivantes Clinic Spandau was previously in South Africa.
Both patients are now housed in isolation.
30 cases of the British variant B.1.1.7 have now been detected in Vivantes clinics - two more than on Thursday.
Both sick people and nursing staff are affected.
Several cases with variants are also known at the Charité.
Both large clinic associations search specifically for mutations via Labor Berlin in order to better assess their spread.
Variants cannot be discovered with the usual PCR test, but can only be detected by means of a complex genome sequencing.

Mutations in the virus can be more contagious and make the pandemic faster.
Scientists therefore see the current lockdown as a measure to stop their spread - as long as not enough people have been vaccinated.
Entry bans from abroad are also planned.
According to the manufacturer, the approved vaccines have so far also been effective against the known mutations.
The degree of widespread use of the new variants in Germany has not yet been precisely recorded; monitoring is currently being expanded.
So far there are around 150 records of mutations in Germany, including a Brazilian one.
"More and more cases and outbreaks are being reported," said Lothar Wieler, head of the Robert Koch Institute (RKI), on Friday.
But that is also due to a more targeted search.
