An asymptomatic coronavirus carrier infected an apartment neighbor without sharing the same space. A study blames the building’s elevator buttons.

CONTROVERSIES IN HOSPITAL INFECTION PREVENTION

By |2020-07-14T15:57:22+00:00July 14th, 2020|

I’m surprised that we can’t stop arguing about the modes of SARS-CoV-2 transmission, despite the fact that most experts (including our friends at WHO) agree on the important issues. Our colleague Jorge Salinas very nicely summarized these issues (and their implications) in this post. The latest kerfuffle: media coverage of 239 experts who are upset that [...]

My wife recently asked me, “Why do you assume you’ll die before me?” It’s true, I have made that assumption. So, I answered, as matter-of-factly as I could, with one word: statistics. I knew that, on average, women live longer than men. In fact, 57% of all those ages 65 and older are female. By age 85, [...]

Another experimental covid-19 vaccine has shown promising early results

Study: Many in US distanced before states mandated it
