Hanover (dpa / lni) - Within a few weeks, a woman from the Hanover region tested positive for Corona twice.
It is still unclear whether she was infected with a mutated virus.
"The investigations are ongoing," said a region spokeswoman on Monday.
Positive samples from people in the vicinity of those affected would also be more precisely determined.
The woman has connections to four daycare centers and a primary school in Hanover over several steps, as the health department announced on Friday.
It ordered quarantine for at least 120 contacts.
The infected woman tested positive for the first time on November 27, the second corona infection was found on January 11.
At the end of December, the Ministry of Health in Hanover announced that the British virus variant B.1.1.7 had been detected for the first time in Lower Saxony.
The Hannover Medical School (MHH) was able to determine it retrospectively in the event of an infection from November.
These are the samples of a very old Covid patient who has now died and his wife.
The couple's daughter was therefore probably infected in England.
With viruses, random changes in the genetic material, called mutations, occur constantly.
Some give the pathogen advantages - for example by making it easier to transmit.
Several Sars-CoV-2 variants are already known.
According to the region spokeswoman, it is unclear when the samples from Hanover will be determined.
