Vaccination rates among kindergartners in Hawaiʻi improved for the 2024-2025 school year compared to the 2023-2024 school year. However, religious exemptions continue to increase across grades K-12.

The Hawaiʻi Department of Health continues to respond to a rise in pertussis (whooping cough) cases statewide. As of July 31, 2025, DOH has identified 203 cases of pertussis – more than double the 84 cases identified in all of 2024. 

The Hawai‘i Department of Health has confirmed one additional case of pertussis (also known as whooping cough) in a third distinct region on Hawaiʻi 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. 

The Hawai‘i Department of Health is investigating two confirmed cases of pertussis (also known as whooping cough) and identified eight probable cases in two separate households without travel-related exposures on Hawaiʻi Island. Both households have school-age children that attend local schools but are in geographically distinct areas of the island. Currently, no one is hospitalized.
