Newly reported coronavirus cases in the U.S. remained under 80,000 for the fourth day in a row, while hospitalizations fell to their lowest level since Nov. 10. The U.S. reported more than 68,000 new cases for Wednesday, according to data compiled by Johns Hopkins University that was published early Thursday. The data may update later. Wednesday’s total was slightly higher than the 62,398 new cases reported the previous day but sharply lower than the daily tally of more than 94,000 a week earlier. (Hall, 2/17)

In its weekly snapshot of the pandemic yesterday, the World Health Organization (WHO) said cases and deaths continue to drop, mainly driven by steep declines in the two highest-burden countries, the United States and the United Kingdom. Also, the B117 virus variant has now been detected in 94 countries spanning all six WHO regions, with local transmission occurring in 47. (Schnirring, 2/17)

California’s coronavirus numbers continue to show signs of improvement. The percentage of coronavirus tests that came back positive over the past seven days — a closely watched indicator for reopening the economy — has dropped to 3.5%. That’s down from over 11% a month ago. Hospitalizations for coronavirus patients have dropped 38% over 14 days, and the rate of infection in the state has fallen to 0.65 — meaning each infected person infects fewer than one other person. “That’s the lowest I’ve seen it,” California Department of Public Health Director Dr. Tomás Aragón said at a meeting of a state vaccine advisory committee on Wednesday. “That’s really good news.” (Vaziri, 2/17)

In early December, Miguel Fernandez lay unconscious in the intensive care unit at a Los Angeles area hospital. A mechanical ventilator pumped oxygen into his lungs, which had been ravaged by COVID-19. The 53-year-old was dying. The best, and likely only, chance of Miguel surviving was a therapy called extracorporeal membrane oxygenation, better known as ECMO. It would allow his lungs to rest while a machine infused his blood with the oxygen he needed. But PIH Health Whittier Hospital, where he had been admitted, didn’t have any ECMO machines or the highly trained staff needed to run them. Only a handful of hospitals in southern California did, and they were overrun with COVID-19 cases. (Armstrong and Allen, 2/18)

Pregnant women in Washington state were infected with COVID-19 at a 70% higher rate than others of similar ages, with nonwhite women shouldering a disproportionate burden, according to a study published yesterday in the American Journal of Obstetrics & Gynecology. Noting that population-based estimates of coronavirus infections in pregnancy are unreliable due to incomplete recording of pregnancy status or inclusion of only hospitalized patients, a team led by researchers from the University of Washington in Seattle analyzed data from 240 pregnant COVID-19 patients at 35 healthcare systems, capturing 61% of the state's annual births, from Mar 1 to Jun 30, 2020.

Computed tomography, magnetic resonance imaging (MRI), and ultrasound scans should be used to help diagnose and treat COVID-19 symptoms, according to a review published today in Skeletal Radiology. While COVID-19 infection is most known for its respiratory ailments, musculoskeletal symptoms such as muscle pain and inflammation, peripheral neuropathy, joint pain, and clotting issues can cause short- or long-term issues, the researchers write.

As Southern California last month reeled from a COVID-19 surge that overwhelmed hospitals, bottlenecked ambulance systems and killed thousands, a physician hosted a conference in Culver City. Peter Diamandis, who is also an engineer, executive and scientist, believed he could create an “immunity bubble” and safely host a scaled-down version of his pricey annual tech conference. Instead, the conference became a superspreader event that infected 24 people, including Diamandis, with the novel coronavirus. (Logan, 2/17)
