DOH confirms additional case of whooping cough on Hawai‘i island

HONOLULU—The Hawai‘i Department of Health (DOH) has confirmed one additional case of pertussis (also known as whooping cough) in a third distinct region on Hawai‘i island which is unrelated to previous cases. This new case closely follows 10 recently reported cases and brings the total to 11 pertussis cases on the Island from March – April 2024. Several of the recent cases have occurred in infants too young to be fully vaccinated.

These recent cases indicate community spread of pertussis on Hawai‘i island. DOH strongly recommends staying up to date with pertussis vaccinations. This is very important for infants, young children, those with underlying medical conditions and their close contacts. We want to protect these vulnerable groups who are more likely to develop severe whooping cough.

Pertussis vaccination can usually be obtained from a primary care provider such as a pediatrician, family physician, internal medicine physician, or nurse practitioner. Calling ahead to confirm pertussis vaccine availability is recommended. Those who do not have a primary care provider can contact their health plan or can contact a federally qualified health center if they do not have health insurance.

Pertussis is a highly contagious respiratory infection caused by bacteria. It can cause severe coughing fits (up to 10 weeks or more), followed by a high-pitched “whoop” sound when breathing in. Vomiting and exhaustion may also follow.

Pertussis can lead to serious complications, especially in infants, such as pneumonia, dehydration, seizures, and brain damage. Some infants may not cough at all. Instead, they may have apnea (life-threatening pauses in breathing) or struggle to breathe.
