The virus has been adapting to its human hosts.
NEW YORK - The following is a brief roundup of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.A genetic analysis of samples from more than 7,500 people infected with COVID-19 suggests that as the new coronavirus spreads quickly around the world, it is adapting to its human hosts, researchers reported on Tuesday in the medical journal Infection, Genetics and Evolution.
"All viruses naturally mutate," Francois Balloux of University College London, who co-led the research, told Reuters."Mutations in themselves are not a bad thing and there is nothing to suggest SARS-CoV-2 is mutating faster or slower than expected. So far, we cannot say whether SARS-CoV-2 is becoming more or less lethal and contagious.
Among their specific recommendations are changes to practice, such as screening stations to funnel infected patients to specific areas, redesigning of procedures that pose high risks for spread of infection, and reducing the density of patients on wards. They wrote on Tuesday in The BMJ that interventions shown to be helpful in the earlier studies"were similar despite the wide range of settings and types of outbreaks ... and thus could be applicable to the current COVID-19 outbreak.
