A new COVID subvariant spreads rapidly as Trump pivots away from vaccines
A new COVID subvariant spreads rapidly as Trump pivots away from vaccines
“A new, highly transmissible COVID subvariant has been detected in California — heightening the risk of a potential summer wave as recent moves by the Trump administration threaten to make vaccines harder to get, and more expensive, for many Americans, some health experts warn.”

We Need Mandatory Masking in Healthcare, and We Need it Now

“We are in year six of the Covid pandemic, and patients are still struggling to access safe healthcare. Hospitals removed mask mandates, didn’t bother upgrading their air quality or ventilation, and stopped requiring staff to test or isolate for Covid.

As a result, Covid aware patients have to take enormous steps to protect themselves in the one place they should have a reasonable expectation of safety.”

Evidence from whole genome sequencing of aerosol transmission of SARS-CoV-2 almost 5 hours after hospital room turnover
Evidence from whole genome sequencing of aerosol transmission of SARS-CoV-2 almost 5 hours after hospital room turnover
“Airborne SARS-CoV-2 may transmit infection after more than 4 hours.”
Experimental evidence suggests that Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) remains viable within aerosols with a half-life of approximately 3 hours; however, it remains unclear how long airborne SARS-CoV-2 can transmit infection. Whole genome sequencing during an outbreak suggested in-room transmission of SARS-CoV-2 to two patients admitted nearly 2 and 5 hours, respectively, after discharge of an asymptomatic infected patient. These findings suggest that airborne SARS-CoV-2 may transmit infection for over 4 hours, even in a hospital setting.

Closing toilet lid before flushing doesn't keep viral spray inside, study suggests
people w/COVID-19, even those who are asymptomatic, excrete severe acute respiratory syndrome coronavirus (SARS-CoV-2) in fecal matter & other excretions," the researchers wrote. "Viruses contaminating urine & feces can be aerosolized in building restrooms during toilet flushing

Higher doses of SarsCov2 at exposure correlate with higher viral loads and severe symptoms in animals.

The more virus you are exposed to the more severe your disease. (HINT: masks work to lower viral loads)
