The RKI and laboratories in Germany have analyzed more than 23,000 positive polymerase chain reaction (PCR) tests. The results showed that the variant identified in the UK already accounted for more than 22 percent of all new infections.

BERLIN, Feb. 17 (Xinhua) -- The more contagious variants of coronavirus are spreading rapidly in Germany, Minister of Health Jens Spahn told journalists here on Wednesday.

In particular, the variant that was first detected in the United Kingdom (UK) is "causing us concern," Spahn said. "We must expect that variant to soon become the dominant one in our country as well."

The Robert Koch Institute (RKI) and laboratories in Germany have analyzed more than 23,000 positive polymerase chain reaction (PCR) tests. The results showed that the variant identified in the UK already accounted for more than 22 percent of all new infections, according to Spahn.

Two weeks ago, the share of the variant known as B.1.1.7 in the examined samples stood at six percent only, the RKI said.

"As has been observed in other countries, the share of infections with this variant of the virus doubles around every week," Spahn said.
