NEW DELHI: Indian Prime Minister Narendra Modi directed local authorities on Saturday to increase their COVID-19 preparedness and review the country’s reopening for foreign arrivals, amid global concerns over the emergence of a new coronavirus strain. The emergence of the omicron variant comes as India has managed to control the outbreak after facing a deadly COVID-19 wave which, fueled by the highly transmissible delta variant, killed over 450,000 people between March and May. The South Asian nation announced on Friday it would reopen for international flights from Dec. 15, after more than 20 months of having its borders shut to stop the spread of COVID-19. On Saturday, Modi requested that the reopening plan be reviewed. “PM asks officials to review plans for easing of international travel restrictions in light of the emerging new evidence,” his office said in a statement. Modi also requested that technical support be provided to regions reporting high numbers of new infections and ordered coordination to ensure the proper functioning of oxygen plants and ventilators. As India has so far fully vaccinated some 35 percent of its 1.3 billion population, the prime minister’s office said he had told officials to accelerate second-dose coverage. Authorities in Mumbai, the financial center and industrial hub of India, have already announced that inbound passengers from South Africa will be quarantined on arrival and those who test positive for COVID-19 will have their samples sent for genome sequencing. “There are concerns in Mumbai about the new variant of coronavirus,” Mumbai mayor Kishori Pednekar told reporters on Saturday. “There is an increased risk of COVID-19 in other nations, so those coming from abroad will have to undergo genome test.” Prof. Rama V. Baru, epidemiologist at the Center of Social Medicine and Community Health at Jawaharlal Nehru University in New Delhi, said genomic sequencing may prove crucial in containing the spread and that a strategy to implement it should be introduced by the Indian Council of Medical Research — the country’s top medical research body. “Testing can be done, but after testing you need to know what is the variant. For that you need genomic sequencing,” she told Arab News. “There has to be a design by which the ICMR comes up with a protocol because they have a network of institutions in different parts of the country. We need to be proactive and quick before the number of patients increases. Once the number increases, our capacity for genomic sequencing is very limited.”
