Taiwan became the latest place to ban arrivals from coronavirus-stricken India on Monday, as it moves to prevent new infections, with more nations reporting cases of a variant first identified in the subcontinent.
The variant, B.1.617, has reached at least 17 countries, from Britain and Iran to Switzerland, sparking global concern and spurring several to close their borders to people travelling from India.
Scientists are studying whether the variant, resulting from two key mutations to the outer "spike" portion of the virus that attaches to human cells, is driving an unexpected explosion in cases in India.
The south Asian nation's tally of infections was just shy of 20 million on Monday, after it reported more than 300,000 new coronavirus cases for a 12th straight day.
"We need to contain these cases, while there are still only a few of them," said Indonesian health minister Budi Gunadi Sadikin, after the first two cases of the variant reported in the southeast Asian nation on Monday.
Neighbouring Malaysia said on Sunday it had detected its first case of the Indian variant, days after imposing a ban on flights from the country.
On Monday, Taiwan said that except for its citizens, all those who had been in India in the 14 days prior would be barred from entering its territory, while returning Taiwanese face 14 days in centralised quarantine facilities.
It was the first time Australia has branded citizens' return home a criminal offence.
Australia defended the ban, which took effect on Monday, saying it had a "strong, clear and absolute" belief that the move was legal. read more
"It's a high-risk situation in India," Health Minister Greg Hunt told a televised news briefing.
Philippine officials warned that they could not rule out the possibility of an India-like COVID-19 crisis, saying last week's decision to ban entry of arrivals from India aimed to keep it from becoming a reality.
"It is possible for it to happen here if we don’t intensify responses," Health Undersecretary Rosario Vergeire said.
"When we look at what is happening in India, it is happening across the globe... What’s different is the intensity of it."
Other strains with known risks, such as those first detected in the Brazil, Britain and South Africa, have been categorised as "variants of concern," a higher threat level.
