As the new strain of Covid-19 Omicron has reached several countries, World Health Organization (WHO) chief Tedros Adhanom Ghebreyesus on Wednesday said there is a “toxic mix” of low vaccine coverage and very low testing—a recipe for breeding and amplifying variants.
“WHO continues to call on all countries to optimize public health and social measures and ensure that high risk and vulnerable individuals in all countries are fully vaccinated,” Tedros said at a press briefing. Tedros suggested against blanked ban on travel and said the variant can be kept in check by mandatory quarantine of international travellers.
On Thursday, the Omicron variant was reported to have reached 24 countries, including Saudi Arabia. The Saudi Press Agency said the citizen carrying the variant came from a North African country.
Amid the scare, the government made RT-PCR mandatory at Delhi airport, for all flyers coming from abroad.
Tedros said: “We are learning more all the time about omicron but there is still more to learn about its effect on transmission, severity of disease and the effectiveness of tests therapeutics and vaccines.” Tedros was keen to call on all countries to rational proportional risk reduction measures in keeping with international health regulations, this includes measures to delay or reduce the spread.
“Several WHO advisory groups have met over the last couple of days to evaluate the emerging evidence, and prioritise the studies needed to answer these questions,” he added. Amid the new variant, many countries have imposed ban on travel since the new strain was discovered at the end of last week.
