Covid -19 hope for severe cases
from Science In Action Hosted by BBC World Service
A multi arm trial testing a range of drugs has shown that readily available steroids can be lifesaving for people severely ill with Covid-19. Max Parmar, head of the UK Medical Research Council’s clinical trials unit says the trial design, where many potential drugs can be tested against the same controls, is key to producing results quickly. As it spreads around the world SARS-CoV-2 is mutating. But what does this mean? These mutations are part of a natural process and some researchers are finding they make no real difference to patient outcomes so far, but others are concerned the virus may become more dangerous. Neville Sanjana from New York University has been running lab tests on the mutant virus. Measles mutated from an animal virus, developing the ability to jump from cattle to human around 2,500 years ago. Sebastien Calvignac-Spencer from Germany’s Robert Koch Institute tracked its origins using preserved lung samples from centuries old measles victims. Covid -19 has become a magnet for conspiracy theorists. A common unfounded claim is that the virus was deliberately manufactured. During the boredom of lockdown such ideas have taken off online, with conspiracy videos receiving millions of views. We speak to scientists who have been targeted, and become the subject of this online misinformation. (Image: Doctor examines Covid-19 virus patient.
