Why India Matters
The prime minister assures us that there's no need to halt flights from India to Canada due to the risk of spreading Covid-19. Mr. Trudeau says his government has all the bases covered. They already have all the needed measures in place.
We've seen Covid variants, mutations, from the UK, Brazil and South Africa. They tend to be more transmissible, i.e. more contagious.
India, the peril du jour, has its own Covid mutation, not one but two mutations.It has two critical mutations that could lead to an improvement in the ability of the virus to bind with human cells. This makes it more effective.
The B.1.617 variant of SARS-CoV-2 carries two mutations, E484Q and L452R. Both are separately found in many other coronavirus variants, but they have been reported together for the first time in India.
What is more worrying is that this variant is showing the ability to escape the human immune system and evade antibodies created by a prior infection or by vaccination.
