The virus will “go away in April,” President Donald Trump told a meeting of governors last month, “as the heat comes in.” That over-confident assertion has attracted criticism from virologists and fact-checkers. Most respiratory diseases — such as influenza and the mundane rhinovirus and coronavirus strains that cause the common cold — do indeed spread more rapidly in the cold, dry conditions of the winter months. But it’s been impossible to say for sure how Covid-19 would behave in summer and late spring for an obvious reason — the strain didn’t exist until around November last year.
