DOH: Hawaii sees ‘worrying’ increase in whooping cough

HONOLULU (KHON2) — A concerning number of pertussis cases in Hawaii, otherwise known as whooping cough, has health officials on high alert.

According to the Hawaii Department of Health, the number of whooping cough cases is increasing at a “worrying rate.”

So far in 2025, officials said 108 cases have been reported, surpassing the 84 total cases for all of 2024.

“Whooping cough is a highly contagious respiratory disease that spreads through the air via the coughs or sneezes of an infected person,” health officials said.

While the symptoms may resemble a cold, it can ultimately progress to “intense coughing fits.”

Officials said health complications can be serious and include pneumonia, seizures, apnea, brain damage and even death.

The DOH said vaccines are the best protection and are urging parents to keep their children up to date on all recommended vaccines such as DTaP or Tdap.
