Online Desk : India`s main opposition leader Rahul Gandhi warned on Friday that unless the deadly second COVID-19 wave sweeping the country was brought under control it would devastate India as well as threaten the rest of the world, reports Reuters.

In a letter, Gandhi implored Prime Minister Narendra Modi to prepare for another national lockdown, accelerate a countrywide vaccination programme and scientifically track the virus and its mutations.

Gandhi said the world`s second-most populous nation had a responsibility in "a globalised and interconnected world" to stop the "explosive" growth of COVID-19 within its borders.

"India is home to one out of every six human beings on the planet. The pandemic has demonstrated that our size, genetic diversity and complexity make India fertile ground for the virus to rapidly mutate, transforming itself into a more contagious and more dangerous form," wrote Gandhi.

"Allowing the uncontrollable spread of the virus in our country will be devastating not only for our people but also for the rest of the world."

India`s highly infectious COVID-19 variant B.1.617 has already spread to other countries, and many nations have moved to cut or restrict movements from India.

British Prime Minister Boris said on Friday the government needed to handle very carefully the emergence of new coronavirus strains in India that have since started to spread in the United Kingdom. read more
