Bremerhaven (dpa / lni) - Corona outbreaks in two fish processing plants in Bremerhaven are due to a virus mutation.
Laboratory tests have shown that, as the city spokesman announced on Friday.
It is therefore still unclear whether it is the English, the South African or the Brazilian variant.
The corona mutant was detected twice in one company and 14 times in the other.
The hygiene and quarantine measures have been tightened for both companies.
The three variants of the corona virus are even more contagious than previous forms.
