The results of genetic sequencing of Hai Duong’s patient recorded 28 cases of the British variant nCoV, a variant of South African infection, the Minister of Health said today.
Mr Nguyen Thanh Long clearly stated that the nCoV strain that is common in Hai Duong is now a UK variant. Furthermore, from the results of the genetic sequencing of a case of a South African variant, it can be shown that some cases were also infected with this strain.
All of these are nCoV variants that are 70% more transmissible than known strains. In which the South African variant is more dangerous than the British variant due to its ability to fool antibodies.
“The health sector is conducting extensive genetic testing to see why South African strains appear in Hai Duong city,” Minister Long said.
After detecting the case of the South African variant of infection, the Ministry of Health ordered Hai Duong a drastic zoning for quarantine and the implementation of epidemic prevention.
