July 14, 2026 - 22:39

The Wyoming Department of Health has confirmed a fifth case of measles in the state this year, marking the fourth infection reported in Teton County. According to health officials, the latest patient is an adult with no known connection to the three earlier cases identified in the same county. The department did not release additional details about the individual's condition or possible exposure locations.

Measles is a highly contagious virus that can lead to serious complications, including pneumonia and encephalitis. The virus spreads through coughing and sneezing, and can linger in the air for up to two hours after an infected person leaves a room. Health officials are urging residents to verify their vaccination status, as the measles, mumps, and rubella (MMR) vaccine remains the most effective way to prevent infection.

The public may have been exposed in various community settings, though the department has not specified where. Officials are working to identify and notify anyone who may have come into contact with the infected individual. This cluster of cases has raised concern among local health authorities, who are reminding residents that symptoms typically appear seven to 14 days after exposure and include high fever, cough, runny nose, and a characteristic red rash.

Anyone experiencing symptoms is advised to call ahead before visiting a healthcare provider to avoid exposing others in waiting rooms. The department continues to monitor the situation closely.
