Well, it happened. After nearly three years of covering COVID and thinking about it almost constantly, it finally got me. But rather than focus on how I got it, I’m going to tell you how I *didn’t* get it for this long. [Thread] From the moment we had evidence that COVID might be airborne, I wore a mask. But not just any mask—an N95 or well-fitted KN95. At first these were really hard to come by, but now it’s quite easy to find them. Here’s how you can find a good one: scientificamerican.com/article/why-we…

You often hear that cities are dangerous places to live, but according to the last 20 years of data, people in rural areas have died at higher rates of all top 10 causes than people in urban areas. By me, with graphics by
@unamandita for @sciam: scientificamerican.com/article/people… Mortality rates in both urban and rural areas fell from 1999 to 2019, but the urban rate started lower and fell faster, the data showed. In 1999 the death rate in rural areas was 7 percent higher than that in urban areas. By 2019, it was 20 percent higher.

N95 respirators provide excellent protection against airborne pathogens. But early in the pandemic, the CDC and WHO recommended against the public wearing them because they were limited and health care workers needed them. Instead they recommended homemade/cloth masks. For several months, N95s, as well as similar masks from China or Korea (KN95s and KF94s) or Europe (FFP2) have been much more widely available. Yet most people are still wearing cloth or surgical masks, which provide worse protection (and often fit poorly).

There's been a lot of talk of vaccine hesitancy/people waiting to get the vaccine "until it's been tested on more people." Here are the facts: [1/6] 2 vaccines have been authorized in the U.S. so far. Pfizer's was tested in ~44,000 people and its efficacy is 95%. Moderna's was tested in ~30,000 and its efficacy is 94%. Both were found to be safe and worked well in all age groups, races and ethnicities. [2/6]
