So far, more than 50 people have died of a febrile illness, though the cause isn’t clear.

Dozens of researchers, including myself, worked for years to uncover that swine flu had leapt to humans from a pig in Mexico in 2009. We learned a lot about influenza evolution, pig farming, and outbreak risk along the way.

COVID-19 affects far more than just the lungs. Researchers are actively documenting the damage the disease causes to the heart, brain, liver, and much more.

Researchers’ painstaking examinations have begun to reveal how the virus wreaks havoc in multiple organs and tissues.

Symptoms documented in cases of long COVID are wide ranging and variable.

A year and a half into the pandemic, the long-term effects of SARS-CoV-2 infection are garnering more research attention as millions of long COVID patients emerge.

The health of the microbial community is associated with COVID-19 severity, but it’s not yet clear if the relationship is causal.

The vaccines remain protective against serious disease and death.

The milestone marks the first fully-approved COVID-19 vaccine in the United States.

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

CDC investigators continue to search for the source of the bacteria that caused four infections—two of them lethal—in four different states. The Scientist spoke with melioidosis expert Bart Currie about the disease.

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.

Depleting intestinal fungi allows radiation to effectively fight cancer, likely because the microbes influence the antitumor immune response.
