‘Indoor ventilation’ can reduce Covid-19 transmission: Study

Live Mint  

A new study has revealed that effective indoor ventilation is required to prevent the spread of Covid-19 transmission. MIT researchers have recently discovered that indoor relative humidity may also affect the virus' ability to spread. The MIT research team reported that around 40% to 60% of indoor relative humidity is associated with relatively lower rates of Covid-19 infections and deaths, …

Two years of COVID: The battle to accept airborne transmission

Al Jazeera  

In the early days of the pandemic, did health authorities get it wrong on airborne transmission? There has been this resistance from people in medical fields, agrees Prather, who says, “They’ve sort of dismissed our opinions.” One of the reasons for that has been the call from certain scientists in the medical field for randomised controlled trials, considered a gold …

Flushing Public Toilets Propels Coronavirus 5 Feet Up in the Air, Indian-origin Researchers Warn

News 18  

Respiratory droplets are the most prominent source of transmission for Covid-19. However, flushing a toilet can generate large quantities of microbe-containing aerosols depending on the design, water pressure or flushing power of the toilet at public restrooms, an Indian-origin researchers-led study has warned. “After about three hours of tests involving more than 100 flushes, we found a substantial increase in …

Boosting Levels of this Protein Reduces the Severity of Covid-19 in Patients, Reveals New Study

News 18  

Researchers have discovered that increased levels of the protein OAS1 are associated with reduced mortality and less severe disease requiring ventilation among patients with Covid-19. Recent advances in proteomic technology — that is, the capacity to isolate and measure hundreds of circulating proteins at once — combined with genetic analyses through Mendelian randomization makes possible the delicate work of untangling …
