Southern Hemisphere DID NOT see a second wave during their winter season8 Sep 2020 12:57
Whilst we already know that Covid is NOT season, we should take comfort that the Southern Hemisphere went through Winter from March and they reported very positive data. Whilst there was some mile increases in covid cases, fundamentaly, hospitalisation and mortality DID NOT increase.
In fact, their seasonal flu reason DIDN'T even come, it was so low it shocked the medical world.
Epidemiologist Cheryl Cohen and colleagues at South Africa’s National Institute for Communicable Diseases (NICD) set up a plan to learn from the double whammy. They hoped to study interactions between seasonal respiratory viruses and SARS-CoV-2, which causes COVID-19. Does infection with one change a person’s risk of catching the other? How do people fare when they have both?
"..the flu season never came. NICD’s Centre for Respiratory Disease and Meningitis, which Cohen leads, has logged only a single flu case since the end of March. In previous years, the country’s surveillance platforms have documented, on average, about 700 cases during that period, Cohen says. “We’ve been doing flu surveillance since 1984, and it’s unprecedented.”
What does this mean?
1. Covid is NOT seasonal
2. Across the southern hemisphere, mortality did NOT increase
