DPHSS: Two cases of whooping cough reported on Guam

The Department of Public Health and Social Services (DPHSS) received two laboratory-confirmed reports of Bordetella Pertussis (pertussis). This brings the total number of confirmed pertussis cases for 2026 to three. Epidemiologic case investigation and contact tracing have been initiated to determine the source of the exposure. DPHSS continues to monitor respiratory illness trends across the island.

Pertussis, commonly known as whooping cough, is a contagious respiratory illness. Early symptoms of whooping cough appear similar to the common cold and usually include runny or stuffy nose, low-grade fever; and a mild, occasional cough. About 1-2 weeks after the first symptoms start, people may develop coughing fits, which can last for several weeks. These coughing fits can cause individuals to make a high-pitched “whoop” when they inhale after a coughing fit, vomit during or after each fit, feel tired, have difficulty sleeping, struggle to breathe, or fracture a rib.

“Babies younger than 1-year old are at greatest risk for whooping cough and having severe complications, such as pneumonia, dehydration, seizures, and brain damage,” said DPHSS Chief Medical Officer Dr. Robert Leon Guerrero. “Some infants may not cough at all. Instead, they may have apnea or struggle to breathe. Individuals with immunocompromising conditions or moderate to severe medically treated asthma are also at high-risk for developing a severe infection. It is important to note that vaccination is effective in preventing pertussis.”
