Why India's Covid crisis matters to the whole world

The harrowing scenes from India have shocked the world, as the country struggles with soaring cases of Covid.

But the outbreak isn't just a crisis for India - it's a crisis for everyone.

"The virus doesn't respect borders, or nationalities, or age, or *** or religion," says Dr Soumya Swaminathan, the World Health Organization's chief scientist.

"And what's playing out in India now unfortunately has been played out in other countries."The pandemic has revealed just how interconnected the world is. And if a country has very high levels of infection, then it's likely to spread to other countries.

Even with travel restrictions, multiple tests and quarantine, infections can still leak out; and if a traveller has come from somewhere where the virus is very prevalent, they have a higher chance of taking the virus with them. On a recent flight from New Delhi to Hong Kong about 50 passengers tested positive for Covid-19.But there's another concern with India's high infection rates: variants.

A new variant has emerged in India called B.1.617. It's been dubbed by some as the "double mutant" because of two key mutations on the spike of the virus. There's some lab evidence that suggests it's slightly more transmissible and that antibodies may find it harder to block the virus, but scientists are still assessing how much immunity is lost.

"I don't think there's any evidence that it's an escape mutation [which would mean] it fundamentally can't be stopped by the vaccines," Dr Jeff Barrett, director of the Covid-19 Genomics Initiative at the Wellcome Sanger Institute, told BBC News.

"I think we have to obviously watch carefully, but there's at present no reason to panic about it."
