Levels of a stringy, spongy substance soar in the sputum of COVID-19 patients requiring intubation, accounting for at least some of their breathing trouble. Development of an off-patent drug may prevent it.

Stanford Medicine now provides a test for the mpox virus. Rapid identification of infected people will help combat the virus’s spread and facilitate patient care.

Children as young as 6 months can now receive the Pfizer BioNTech and Moderna mRNA vaccines.

Using machine learning, researchers from Stanford Medicine and their collaborators found specific genetic signals in people who develop severe coronavirus infection.

Researchers found that damage to the brain’s white matter after COVID-19 resembles that seen after cancer chemotherapy, raising hope for treatments to help both conditions.

People with mild to moderate COVID-19 can shed viral RNA in their feces months after initial infection, Stanford researchers find. Those who do often have nausea, vomiting and abdominal pain.

Using household items, Stanford students have developed a way to make affordable nasal drops with the potential to slow the spread of viruses like COVID-19.

Two-dose COVID-19 vaccines significantly increase protection against hospitalization and death in people who had the illness before they were immunized.

Researchers have created a test that can predict which dengue patients will likely have mild symptoms and which should be clinically monitored for a high risk of severe illness.

Stanford Medicine scientists explain what we know, and what we don’t know, about living with COVID-19 two years after the World Health Organization declared a pandemic.
