At least 22 people died from loss of oxygen in a hospital accident. Infections hit a daily record. And the government faced criticism for allowing an enormous Hindu festival to continue.
In movies such as Contagion, a pandemic begins in a flash. A deadly virus spills over from an animal, like a pig, into humans and then quickly triggers an outbreak. But that’s not actually what happens, says Dr. Gregory Gray at the Duke Global Health Institute. “It’s not like in the movies,” he says, “where this virus goes from a pig in Indonesia and causes a pandemic.”
An unvaccinated health care worker set off a Covid-19 outbreak at a nursing home in Kentucky where the vast majority of residents had been vaccinated, leading to dozens of infections, including 22 cases among residents and employees who were already fully vaccinated, a new study reported Wednesday.
The fight against COVID-19 is a lonely one with patients forced into isolation in intensive care wards, removed from family and friends. But two nurses in the small city of Sao Carlos, in Sao Paulo state, have discovered a way to help with a millimeter of latex and some warm water that mimics a human touch.
To understand how risky it may be to board a flight now, start with how air circulates in a plane.
A Phase 2/3 trial to evaluate a new fully-human polyclonal antibody therapeutic targeted to SARS-CoV-2, called SAB-185, has begun enrolling non-hospitalized people with mild or moderate cases of COVID-19. The trial, ACTIV-2, is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The therapeutic was developed by SAB Biotherapeutics, Inc. (Sioux Falls, South Dakota).
Scientists and public health experts agree that masks are effective at lowering the spread of the coronavirus indoors, where the vast majority of transmission is likely to occur.
Black women are more vulnerable than white men, illustrating how race and gender intersect to shape health outcomes.
For almost a year, Americans have been looking forward to herd immunity, when enough people are protected through vaccination or past infection to stop the spread of COVID-19.
The European Union’s drug regulatory agency said Tuesday that it found a “possible link” between Johnson & Johnson’s COVID-19 vaccine and extremely rare blood clots and recommended a warning be added to the label. But experts at the agency reiterated that the vaccine’s benefits outweigh the risks.
A German scientist studying extremely rare blood clots linked to AstraZeneca’s (AZN.L) COVID-19 vaccine said on Tuesday Johnson & Johnson (JNJ.N) has agreed to work with him on the research after similar serious side effects emerged in recipients of its shot.
A small Israeli study published as a preprint on medRxiv indicated that some of the new coronavirus variants may put people who have been vaccinated at higher risk of a “breakthrough infection.”
Several days after receiving his first dose of a Chinese-made coronavirus vaccine, Rodrigo Jordán fell ill and tested positive for Covid-19. The 61-year-old was hospitalized near his home in the Chilean capital, Santiago, for nine days and needed supplemental oxygen to pull through.
Last month, up to 15 million doses of Johnson & Johnson’s vaccine had to be discarded at Emergent’s factory in Baltimore. A new report says problems were not fully investigated and other doses may be compromised.

Science and Tech
The U.S. government invested $800 million in plasma when the country was desperate for Covid-19 treatments. A year later, the program has fizzled.
Psychological and Sociological Impact
Emerging variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are of clinical concern. In a cohort of 417 persons who had received the second dose of BNT162b2 (Pfizer–BioNTech) or mRNA-1273 (Moderna) vaccine at least 2 weeks previously, we identified 2 women with vaccine breakthrough infection. Despite evidence of vaccine efficacy in both women, symptoms of coronavirus disease 2019 developed, and they tested positive for SARS-CoV-2 by polymerase-chain-reaction testing. Viral sequencing revealed variants of likely clinical importance, including E484K in 1 woman and three mutations (T95I, del142–144, and D614G) in both.
