COVID SCIENCE-Physical inactivity tied to higher COVID-19

By Nancy Lapid April 19 (Reuters) - The following is a roundup of some 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. Physical inactivity tied to higher COVID-19 risks Patients with COVID-19 who have been consistently physically inactive have a significantly higher risk of severe outcomes than patients who were getting at least some exercise or regularly met physical activity guidelines prior to the illness, researchers found. Among the 48,440 patients in their study, 14.4% were consistently inactive in the two years before their COVID-19 diagnosis, 79.1% had some activity, and 6.4% consistently met recommended physical activity guidelines of at least 150 minutes per week. Compared with those who consistently met activity guidelines, people who were consistently inactive were more than twice as likely to be hospitalized and to die from the virus, according to a report in the Briti

Brave Volunteers Are Being Deliberately Reinfected With COVID-19 For Science

AFP 20 APRIL 2021 The University of Oxford said Monday it has launched a trial in which people who have already had COVID-19 are deliberately reinfected. The carefully controlled study will look at the kind of immune response mounted by the volunteers.   The scientists will know exactly when the second infection occurs, and exactly how much virus they got, Helen McShane, a professor of vaccinology, said in a statement. She said the trial may help us to design tests that can accurately predict whether people are protected after a prior infection. Anyone who suffers symptoms will receive the Regeneron antibody treatment used to treat COVID-19 patients.

UK govt gives Ethical nod to study effects of COVID-19 reinfection on immune system

Last Updated: UK Govt Gives Ethical Nod To Study Effects Of COVID-19 Reinfection On Immune System Oxford University researchers have gained ethical approval for a trial that aimed to check the immune response needed to protect people against reinfection. AP As many as 64 healthy young adults aged between 18-30 who have previously contracted COVID-19 and have been completely cured will now be recruited to take part in a new human challenge trial to study how the body s immune system reacts to the COVID-19 virus.  Notably, researchers at Oxford have gained ethical approval for this trial that hopes to check the immune response needed to protect people against reinfection.
