U.S. reports world record of more than 100,000 COVID-19 cases in single day – Reuters

The United States set a new all-time high for coronavirus cases confirmed in a single 24-hour period on Friday, reporting just over 100,000 new infections to surpass the record total of 91,000 posted a day earlier.

The Virus Rate in One Area Plummeted. Experts Wonder Why. – New York Times

The question has become particularly salient in Orange County, the suburban area about 65 miles north of New York City where a skyrocketing case count in mid-October prompted a state-imposed lockdown and drove the positivity rate in an ultra-Orthodox Jewish village up to 34 percent. Two weeks later, the rate has dropped to 2 percent, and restrictions in the area have been eased.

‘A whole lot of hurt’: Fauci warns of covid-19 surge – Washington Post

“We’re in for a whole lot of hurt. It’s not a good situation,” Anthony S. Fauci, the country’s leading infectious-disease expert, said in a wide-ranging interview late Friday. “All the stars are aligned in the wrong place as you go into the fall and winter season, with people congregating at home indoors. You could not possibly be positioned more poorly.”

COVID-19 Hospitalization – NPR

Audio file at the link – As coronavirus cases rise swiftly around the country, surpassing both the spring and summer surges, health officials brace for a coming wave of hospitalizations and deaths. Knowing which hospitals in which communities are reaching capacity could be key to an effective response to the growing crisis. That information is gathered by the federal government — but not shared openly with the public.

How COVID turns our immune defences against us – Nature

The fiendishly complicated relationship between our immune systems and SARS-CoV-2, how scientists are making lab life comfy for ‘extremophile’ microbes and a Trump order alarms US government scientists.

Assessing the potential association between SARS-CoV-2 RNA load in the respiratory tract and COVID-19 mortality – DocWire

The magnitude of nasopharyngeal (NP) SARS-CoV-2 load either at hospital admission or during the course of hospitalization has been directly associated with mortality of COVID-19 patients.

Pregnant women with Covid-19 are more likely to need intensive care, a new C.D.C. study finds – NYT

Federal health officials on Monday added pregnancy to the list of conditions that put people with Covid-19 at increased risk of developing severe illness, including a heightened risk of death. [Related CDC Report]

Doctors Begin to Crack Covid’s Mysterious Long-Term Effects – Wall Street Journal

Severe fatigue, memory lapses, heart problems affect patients who weren’t that badly hit initially; ‘It’s been so long’ Nearly a year into the global coronavirus pandemic, scientists, doctors and patients are beginning to unlock a puzzling phenomenon: For many patients, including young ones who never required hospitalization, Covid-19 has a devastating second act.

Add Skin Conditions to COVID-19 Long-Hauler Effects – MedPageToday

Benign but potentially painful skin conditions may persist for months in some patients with COVID-19, preliminary data from an international registry suggested. [Related article: COVID Toes and Fingers, Several Coronavirus Patients Experience Purple Skin Rashes]

Lung Ultrasound Beats X-Rays in COVID Pneumonia Screening – MedPageToday

Portable ultrasound scans were more sensitive than x-rays at the preliminary detection of atypical pneumonia in patients who may have COVID-19, a researcher reported.

Interferon deficiency can lead to severe COVID – Nature

Understanding what contributes to the development of severe COVID-19 would be of great clinical benefit. Analysis of people in whom this occurred pinpoints a key role for the signalling pathway mediated by type I interferon proteins.

Age-specific mortality and immunity patterns of SARS-CoV-2 – Nature

Estimating the size and infection severity of the SARS-CoV-2 epidemic is made challenging by inconsistencies in available data. The number of COVID-19 deaths is often used as a key indicator for the epidemic size, but observed deaths represent only a minority of all infections1,2. Additionally, the heterogeneous burden in nursing homes and variable reporting of deaths in elderly individuals can hamper direct comparisons across countries of the underlying level of transmission and mortality rates3. Here we use age-specific COVID-19 death data from 45 countries and the results of 22 seroprevalence studies to investigate the consistency of infection and fatality patterns across multiple countries.

Science and Tech

Covid-19 “super-spreading” events play outsized role in overall disease transmission – MIT Tech Review

Mathematical analysis suggests that preventing large gatherings could significantly reduce Covid-19 infection rates. There have been many documented cases of Covid-19 “super-spreading” events, in which one person infected with the SARS-CoV-2 virus infects many other people. But how much of a role do these events play in the overall spread of the disease? A new study from MIT suggests that they have a much larger impact than expected.

T-cell study adds to debate over duration of COVID-19 immunity – Retuers

A small UK study has found that “cellular immunity” to the pandemic SARS-CoV-2 virus is present after six months in people who had mild or asymptomatic COVID-19 infections – suggesting they might have some level of protection for at least that time.

The COVID conspiracy theory that won’t go away: No, the novel coronavirus was not made in a lab — it came from bats – Genetic Literacy Project

One of the conspiracy theories that have plagued attempts to keep people informed during the pandemic is the idea that the coronavirus was created in a laboratory. But the vast majority of scientists who have studied the virus agree that it evolved naturally and crossed into humans from an animal species, most likely a bat.
