As communities and businesses reopen amidst the pandemic, masks—in addition to other social distancing measures—are crucial for preventing new outbreaks.

In just a few months, researchers have constructed low-cost ventilators that can keep sedated pigs alive. Getting them to work safely and reliably in people is the next challenge.

An open letter points to outbreaks that cannot be explained by large droplets and contact with surfaces alone.

Onsite testing at wastewater treatment plants could aid efforts to monitor for outbreaks of COVID-19 around the world, but such technologies are in the early stages of development.

A nearly all-female team of researchers developed a PCR diagnostic tool in a record-setting six weeks.

Social distancing measures prevented millions of COVID-19–related deaths around the world, according to a handful of studies, but it’s hard to quantify the effects with certainty.

Vaccine experts divided on whether that level of protection is too low or too demanding.

SARS-CoV-2 causes cells to put out projections that spread the virus, a study finds.

An influenza virus identified in pigs in China has a concerning mix of genes, but experts say there is no way to know if it will evolve to be transmissible between humans.

The results, while preliminary, suggest that survivors of SARS-CoV-2 infection may be susceptible to reinfection within weeks or months.

The company behind a now-discredited study on hydroxychloroquine also posted a report that has been cited by Latin American governments recommending ivermectin as a possible coronavirus treatment. Clinicians there say the effects have been extremely damaging.

Hydroxychloroquine and chloroquine, once thought to be promising COVID-19 treatments, come with serious heart risks.

A study of 34 children hospitalized with a coronavirus infection in China reveals that fever and coughing were common, but the type of lesions typically seen in the lungs of adults with COVID-19 were rare.

Accounting for a limited stockpile of cholera vaccine can provide insight into the most effective way to distribute future COVID-19 vaccines.
