What's Happening?
Kentucky is experiencing a significant increase in pertussis cases, marking the largest spike since 2012. As of November 19, 2025, there have been 566 reported cases of whooping cough in the state, with health officials expecting more cases as the year
progresses. The disease poses the greatest risk to infants under one year old, and the recent death of a third unvaccinated infant has heightened concerns. The Kentucky Department of Public Health has confirmed that none of the deceased infants or their mothers were vaccinated against pertussis. The decline in vaccination rates is evident, with only 86% of kindergarteners and 85% of seventh-graders up to date on their whooping cough vaccines, according to the 2024-2025 Kentucky school immunization survey. Public health officials are urging residents to ensure they are vaccinated, particularly pregnant women, to protect their babies.
Why It's Important?
The rise in pertussis cases in Kentucky underscores the critical importance of maintaining high vaccination rates to prevent outbreaks of contagious diseases. The decline in vaccination rates poses a significant public health risk, particularly to vulnerable populations such as infants. The situation in Kentucky reflects a broader national trend of decreasing vaccination rates, which could lead to more widespread outbreaks of preventable diseases. Public health officials emphasize that vaccination not only protects individuals but also helps safeguard the community by preventing the spread of infectious diseases. The recent infant deaths highlight the urgent need for increased public awareness and adherence to vaccination schedules to prevent further tragedies.
What's Next?
Health officials in Kentucky are likely to intensify efforts to promote vaccination and educate the public about the importance of immunizations. This may include targeted campaigns to increase vaccination rates among school children and pregnant women. The state may also consider implementing stricter vaccination requirements or policies to ensure higher compliance. Additionally, public health departments may collaborate with local healthcare providers to facilitate access to vaccines and provide information on the benefits of immunization. Monitoring and reporting of pertussis cases will continue, with potential adjustments to public health strategies based on the evolving situation.
