This is what we know so far about how covid-19 affects the rest of the body – MIT Tech Review

Covid-19 is primarily a respiratory infection that attacks the lungs, making it harder for patients to breathe and get enough oxygen to the rest of the body. Pneumonia and other respiratory conditions can quickly set in, eventually leading to death if the body cannot fight off the infection. But after over four months of cases, doctors are getting a more detailed look at some of the unexpected ways the virus hits the human body beyond the nasal cavity, throat, and lungs. Here are a few new things we’ve learned in recent weeks:

Places without social distancing have 35 times more potential coronavirus spread, study finds – Washington Post

For social distancing policies that lasted at least 16 to 20 days, the daily rate of infection dropped by more than 9 percentage points, according to the study. Policies lasting 15 days and less also saw declines in the daily infection rate, researchers found. Such social distancing measures, mandated by 95 percent of the country, include shelter-in-place orders, school closures, bans on large events and the closure of gyms, bars and restaurants.[Related Study]

Loud talking could leave coronavirus in the air for up to 14 minutes – MIT Tech Review

Thousands of droplets from the mouths of people who are talking loudly can stay in the air for between eight and 14 minutes before disappearing, according to a new study. The research, conducted by a team with the US National Institutes of Health and published in PNAS Wednesday, could have significant impact on our understanding of covid-19 transmission.

Covid-19 update: 2 US pork processors change course – Pig Progress

In the United States in recent weeks, temporary packing plant closures due to Covid-19 outbreaks among workers have caused widespread processing backlogs. Experts put the number of hogs ready for slaughter (but not able to be processed) at the end of April at 1 million. Many hogs had to be euthanised. In the state of Minnesota, reported AgWeek, a large site was created to receive thousands of dead hogs each day for composting.
