Indian Covid mutant more contagious, but not vaccine resistant: Top WHO scientist

“Surge in India increases chances of more dangerous variants emerging. Prelim data shows that Indian variant is more contagious. There is heterogeneity in India in terms of spread of Covid-19. WHO is concerned about number of cases and deaths in India. Globally, cases and deaths have plateaued, not in South Asia. South East Asia is seeing case rise owing to India. Overall numbers hide what is going on, need to go deeper in state, local level data,” she said.

‘Speaking on efficacy of vaccines available in India, she assured, “There is no enough data to show that double mutant is vaccine resistant. All the available vaccines today in India and elsewhere prevent severe disease and death even if you get up the infection. You are not going to end up in the ICU critically ill. The message is take the vaccine whichever is available and you eligible for it. If your turn is there, please take it.”

Regular exercise can reduce the risk of severe outcomes for Covid-19, says study

‘Doctors at Kaiser Permanente Southern California, who led the study, included 48,440 subjects who were diagnosed with COVID-19 between January 2020 and October 2020 and asked them how often they’d exercised over the previous two years. They measured answers by the Exercise Vital Sign, a standard that identifies whether people are meeting the government’s Physical Activity Guidelines for Americans. The most recent version, updated in 2018, recommends that on a weekly basis, adults do 150 minutes to 300 minutes of moderate-intensity exercise or 75 minutes to 150 minutes of vigorous-intensity exercise, with additional guidelines for strength training.    

‘These are the main findings: 

• People who were “consistently inactive,” meaning they exercised anywhere from zero to 10 minutes per week, had a 2.26 greater chance of hospitalization, a 1.73 greater chance of ICU admission and 2.49 greater odds of death from COVID-19 compared to patients who were consistently active. 
• People who did “some activity,” which equaled anywhere from 11 to 149 minutes per week, had a 1.89 greater chance of hospitalization, a 1.58 greater chance of ICU admission and a 1.88 times greater chance of death than those who were consistently active.’
