China could face a catastrophic COVID surge as it lifts restrictions – here’s how it might play out

Given the low level of immunity in China, a major surge would likely see large numbers of hospitalisations and might lead to a dramatic death toll. If we assume, say, 70% of the Chinese population becomes infected over the coming months, then if 0.1% of those infected die (a conservative estimate ), a back-of-the-envelope calculation suggests we’d see around one million deaths.

Strep A: three doctors explain what you need to look out for

Group A streptococcus is a type of bacteria that can live in the back of the throat or on the skin, especially in children. It can spread between people through close contact or coughing and sneezing. In most people, it either causes no illness or only mild throat or skin infections or scarlet fever. Children with scarlet fever have a sandpaper-like rash over their body, often with fever and sore throat and a “strawberry tongue” – where the tongue is red with a white covering.

Pandoravirus: the melting Arctic is releasing ancient germs – how worried should we be?

All the viruses cultured so far are far from viruses that affect mammals, let alone, humans and would be very unlikely to pose a danger to humans. A more relevant area of concern is that as the permafrost thaws it could release the bodies of long-dead people who might have died of an infectious disease and so release that infection back into the world.
