Vietnam’s Health Ministry announced Saturday that it had detected a highly transmissible new variant of the coronavirus that has helped fuel a recent wave of infections in the country.
The minister said the new variant was particularly contagious via air and viral cultures have revealed it replicates extremely quickly, the newspaper reported.
“The new variant is very dangerous,” Long said in a statement.
The Health Ministry didn’t return a Saturday afternoon request for comment.
Scientists said further study was needed to determine the effect of a variant in “real-world settings.”
“A lot of different mutations happen as the virus is transmitted and most of them are not of clinical significance,” said Todd Pollack, a Hanoi-based infectious-disease expert for Harvard Medical School. “Just because they say [the new variant] has features of one and the other … doesn’t mean they got together in one patient and spit out some combined hybrid ‘supervirus.’ ”
There were seven known coronavirus variants in Vietnam before Long’s announcement, according to Reuters.
Vietnam, which has reported around 6,400 coronavirus infections and 47 deaths, has been one of the world’s coronavirus containment success stories. A well-run public health-care system, quarantine camps operated by the military and strict, targeted lockdowns kept case numbers low until late April, when a spike in infections began.
Many of the recent infections were detected in two industrialized provinces in northern Vietnam, where factory employees often work in proximity. Plants there that manufacture for such global brands as Apple have implemented social distancing measures, Reuters reported. Such factories are key to Vietnam’s export sector, which has boomed amid trade tensions between the United States and China.
Restrictions are also in place in Hanoi, the capital, and Ho Chi Minh City, the country’s economic hub.
Many countries that managed the pandemic with “non-pharmaceutical interventions are finding that more transmissible variants are more difficult to control with these measures,” Pollack said. “This is the biggest challenge that [Vietnam is] facing since covid-19 came onto the scene.”
Vietnam is operating one of the slower inoculation programs in the world, with fewer than 0.1 percent of its 103 million residents having been fully vaccinated as of Friday. It has approved the Oxford-AstraZeneca and Sputnik V shots and recently signed a deal to buy more than 30 million Pfizer-BioNTech vaccine doses. Vietnam is also developing its own Nanocovax vaccine, whose final-stage trials are set for completion in the second half of the year.
Hanoi has a rocky relationship with Beijing and, unlike many other middle income nations, it has not approved the use of Chinese-developed vaccines.
