Officials say it’s not yet clear whether this case is linked to an outbreak in Guinea earlier this summer.

The makers of the CRISPR-based testing platform, called miSHERLOCK, say it could enable people at home or physicians in resource-limited environments to detect SARS-CoV-2—and eventually, other pathogens.

The finding of the Ebola-like disease, which killed a man in Guinea, has prompted public health measures.

An ability to build up higher concentrations of viral particles in people’s airways and mutations that might boost its ability to infect human cells could be what gives the Delta variant its evolutionary edge.

Surveillance networks set up to detect outbreaks among pets could one day have public health uses too.  

By measuring various pollutants in the immediate vicinity of pregnant women and tracking brain development of their children, researchers in Barcelona aim to untangle any influence the former has on the latter.

Some of the blood specimens collected in the United States for the NIH’s All of Us research program starting on January 2, 2020, have antibodies against SARS-CoV-2.

Influenza RNA sequences from three sets of lungs preserved in formalin since 1918 provide new insights into the deadly pandemic.

A modeling study of boarding behavior finds filling the plane from back to front extends the close contact time between passengers and therefore increases the risks posed by air travel.

Scientists at the US CDC report no red flags in a preliminary analysis of the safety of Pfizer/BioNTech’s and Moderna’s mRNA-based immunizations among expectant mothers.

Researchers involved in a long-term project to identify viruses of concern have now assessed the risk factors that could help forecast which pathogens are the most likely to spillover from wildlife to people.

A review of hundreds of cases finds that only a minority of patients noted being sick with a coronavirus infection prior to developing the severe inflammatory condition.

Martha Nelson of the National Institute of Allergy and Infectious Diseases talks about the need to balance data sharing and patient privacy concerns when tracking the spread of variants.

A review article containing contested claims about the tropical medicine drug as a COVID-19 treatment was listed as “provisionally accepted” on the journal’s website before being removed this week.

Death rates among blood cancer patients who contract COVID-19 are higher than for those with other cancers, pointing to impaired immunity that makes it hard to overcome the virus.

The woman may have had a link to another person, who was married to an Ebola survivor and who died a few days previously in Democratic Republic of Congo.

A study of people in Sierra Leone suggests that the virus can lie in hiding from the immune system before re-emerging later and sparking a new response—although researchers didn’t examine whether this could make people infectious again.

Scientists across the world are closely tracking the spread of mutations in the coronavirus and investigating whether they could render current vaccines less effective.

As politicians try to schedule an end to the pandemic, scientists say the virus will stick around as an endemic disease similar to the common cold.
