Real-world data show that filters clean COVID-causing virus from air

Research at a hospital swamped by people with COVID-19 has confirmed that portable air filters effectively remove SARS-CoV-2 particles from the air — the first such evidence in a real-world setting1. The results suggest that air filters could be used to reduce the risk of patients and medical staff contracting SARS-CoV-2 in hospitals, the study’s authors say....

Analysis of racial/ethnic disparities in excess deaths among minorities in the U. S. in 2020 during the COVID-19 pandemic

Racial and Ethnic Disparities in Excess Deaths During the COVID-19 Pandemic, March to December 2020

Although racial/ethnic disparities in U.S. COVID-19 death rates are striking, focusing on COVID-19 deaths alone may underestimate the true effect of the pandemic on disparities. Excess death estimates capture deaths both directly and indirectly caused by COVID-19. ...

An estimated 2.88 million deaths occurred between March and December 2020. Compared with the number of expected deaths based on 2019 data, 477 200 excess deaths occurred during this period, with 74% attributed to COVID-19.

Age-standardized excess deaths per 100 000 persons among Black, American Indian/Alaska Native (AI/AN), and Latino males and females were more than double those in White and Asian males and females.

Covid Testing--Opinion: Rapid Tests Are the Answer to Living With Covid-19

https://www.nytimes.c

In Germany, you can buy a rapid Covid-19 test at the grocery store for one euro (a little more than a dollar). In Britain, any household can obtain a pack of seven rapid tests every day for free. In Singapore, you can get a free rapid test from a vending machine. Families in Israel receive at-home rapid tests for their children to use before school. Rapid testing is commonplace in many parts of the world because policymakers recognized early on that the tests could blunt the pandemic by stopping chains of transmission. By letting people know they are infectious, rapid tests are useful even in areas with high vaccination rates and can allow for a safer return to in-person activity.
