Vietnam discovers new Covid variant spreads quickly by air
Vietnam has discovered a new Covid-19 variant which spreads quickly by air and is a combination of the Indian and British strains, state media reported on Saturday.
The country is struggling to deal with fresh outbreaks across more than half of its territory including industrial zones and big cities such as Hanoi and Ho Chi Minh City.
More than 6,700 cases including 47 deaths have been reported in Vietnam — the lion's share have occurred since April.
"We have discovered a new hybrid variant from the Indian and the UK strains," Health Minister Nguyen Thanh Long was quoted telling a national meeting on the pandemic Saturday.
"The characteristic of this strain is that it spreads quickly in the air. The concentration of virus in the throat fluid increases rapidly and spreads very strongly to the surrounding environment."
He did not specify the number of cases recorded with this new variant but said Vietnam will soon announce the discovery in the world's map of genetic strains.
There were seven known coronavirus variants in Vietnam before Long's announcement, according to the Ministry of Health.
The communist country has previously received widespread applause for its aggressive pandemic response, with mass quarantines and strict contact tracing helping keep infection rates relatively low.
The new round of infections has made the public and government fearful and authorities quickly moved to place strict limits on movement and business activity.
Cafes, restaurants, hair salons and massage parlours as well as tourism and religious spots have been ordered to close in various areas of the country.
Vietnam — a country of 97 million people — has vaccinated a little over a million citizens.
It is now ramping up its jab rollout and hopes to achieve herd immunity by the end of the year, according to the minister for health.
