It may already be too late for the world Regarding India's Variants

 As countries around the world airlift oxygen, vaccines and medical supplies to India, they are also closing their borders to the world’s second most populous country. It may already be too late. The B.1.617 variant of the virus, first detected in India, has now been found in 44 countries on every continent except Antarctica—including Nepal, the U.S. and much of Europe. Scientists say it could be more infectious and better at avoiding humans’ immune systems. On May 10, the World Health Organization declared it a variant of “global concern.” And because only around 0.1% of positive samples in India are being genetically sequenced, “there may well be others that have emerged,” says Amita Gupta, deputy director of the Johns Hopkins University Center for Clinical Global Health Education.

 They are not certain what this variant and others will do when they hit the 44 countries on earth that it has hit already including the U.S. and others in the future. There are many unknowns for the world now.

One possibility is that whole families that are unvaccinated now will be in the hospital together just like they have been in India these past few weeks.
