A cluster of one confirmed and five suspected hantavirus infections on a cruise ship has left three passengers dead, according to the World Health Organization. The outbreak is drawing attention to a virus family better

The FDA has approved Merck’s Idvynso, a once-daily two-drug tablet for certain adults with HIV-1, adding a new oral option for people who are already virologically suppressed.

A new PNAS-linked study reports that genetic exchange is widespread across natural populations of Leishmania, challenging the long-held view that the parasites spread mainly through clonal reproduction.

A new Lancet analysis says the United States has already missed four of the CDC’s seven measles-elimination indicators, with the others increasingly at risk after outbreaks spread to 45 states.

Researchers have developed a fluorescent biosensor that detects a protein secreted during active tuberculosis, aiming to deliver a faster and more clinically specific diagnostic tool than conventional culture methods.

Doctors are seeing rotavirus infections earlier in the season than usual, but the effect of widespread vaccination remains clear: far fewer children are ending up in the hospital.

A first Victorian phage-therapy case points to an overlooked challenge: some patients may carry antibodies that neutralize the very viruses meant to kill drug-resistant bacteria.

A new report says keratinocytes may actively help rabies invade nerves after minor bites or scratches, challenging the idea that skin cells are only passive conduits.

Scientists led by Nanyang Technological University, Singapore, report that proteins found in urine can predict which dengue patients are more likely to progress to severe disease, opening the door to simpler risk triage.

Researchers at Karolinska Institutet report an association between gut bacteria composition and the level of latent HIV in people receiving antiretroviral therapy, pointing to a possible new line of investigation in cure

Doctors described an unusual parasitic fly infection in a 58-year-old woman in Greece, underscoring how rare cases can challenge standard diagnostic assumptions.

A study published in Nature Microbiology reports that a virus usually associated with shrimp and fish has crossed into humans and is tied to persistent eye disease.

A new Nature Medicine report describes the detection of mpox clade IIb in the Republic of the Congo alongside clades Ia and Ib, highlighting a more complex outbreak picture and the need for stronger surveillance and case

A long-stagnant field is moving again as tuberculosis drug and vaccine development reaches its broadest pipeline on record, raising the prospect of shorter treatments and the first new vaccine class in a century.

A new mRNA vaccine targeting the Nipah virus—one of the world's most feared potential pandemic pathogens—proved safe and generated strong immune responses lasting at least one year in a phase 1 clinical trial published in Nature Medicine.

With nearly 1,000 confirmed measles cases in 2026 spread across close to half of U.S. states, public health officials are sounding the alarm about a broader crisis. Declining vaccination rates could open the door to resurgences of mumps, hepatitis B, and other diseases once thought conquered.

Researchers have found that Chlamydia pneumoniae, a widespread bacterium known for causing respiratory infections, can invade the brain and retina where it persists for years, triggering inflammation and amyloid-beta accumulation linked to Alzheimer's disease. The discovery opens new avenues for early detection through retinal imaging and potential antibiotic treatments.
