The Guam Department of Public Health and Social Services has confirmed a new report of pertussis, also known as whooping cough.
This is the fifth case of pertussis in 2025, and contact tracing has been initiated to determine the source of the exposure.
Pertussis is a highly contagious respiratory infection caused by bacteria. It can cause severe coughing lasting up to 10 weeks or more, followed by a high-pitched “whoop” sound when breathing in.
The disease can be prevented by a vaccine.
According to the Centers for Disease Control and Prevention, pertussis can be serious at any age, but it is particularly dangerous for babies.
Complications include pneumonia, dehydration, seizures and brain damage.
