Buried in today’s political news was a new COVID-19 study from Texas that found that the virus is becoming more contagious, and possibly increasingly able to circumvent control measures such as masks, hand-washing, and social distancing.
It’s really depressing news, though not really unexpected. What the researchers found was that 99.9 percent of recent cases in Houston appear to come from a previously uncommon strain of the virus—one that produces greater numbers of virus particles in their noses, mouths, and lungs. That means that when they breath, talk, shout, cough or sneeze, they expel more virus particles, increasing the chance that someone nearby will receive an infectious dose.
The paper is posted on MedRxiv, an online site where scientists can post preliminary results while awaiting official publication. And while that means it isn’t peer reviewed, this doesn’t appear to be the type of research that can be easily messed up—especially if we don’t really care whether it’s 99.9 percent of new cases or 99 percent, or even 90 percent.Continue reading COVID-19 Becoming More Infectious, Study Says
