California Whooping Cough Cases Increased 500%

The California Department of Public Health (CDPH) recently announced that pertussis (whooping cough) cases are increasing throughout the state. It urged pregnant women and infant caregivers to receive tetanus, diphtheria, and pertussis vaccinations.

CDPH reported receiving reports of more than 2,000 patients, including 62 infants hospitalized during the last ten months of 2024. One of the hospitalized infants died from the pertussis infection.

This data represents about a 500% increase in cases than in 2023 when 400 pertussis cases were confirmed.

Dr. Tomás J. Aragón, CDPH Director and State Public Health Officer stated in a press release on January 3, 2025, "Infants are particularly vulnerable (the bacterial disease), and that's why CDPH especially encourages people who are pregnant to receive the Tdap vaccine in their third trimester, which will pass along protective antibodies to the baby." 

Throughout the USA, the Centers for Disease Control and Prevention (CDC) note that six times as many pertussis cases were reported in 2024 compared to 2023.

Caused by Bordetella pertussis, people with whooping cough have severe coughing attacks that can last for months, according to the CDC. Infants too young for vaccination are at the most significant risk for hospitalization and death. Early signs of whooping cough are similar to common cold symptoms, such as a runny or stuffy nose and low-grade fever. Babies with whooping cough may have trouble breathing, turn blue, or stop breathing. 

The CDC and CDPH recommend speaking with your doctor or pharmacist in 2025 about which vaccines are right for you and your family.
