On November 29, 2025, the Centers for Disease Control and Prevention (CDC) issued a warning about the continued high incidence of whooping cough, also known as pertussis, across the United States. The CDC highlighted that the number of reported cases this year is significantly higher than historical norms, signaling an ongoing public health concern as the year draws to a close.
Health officials are particularly concerned as winter approaches, traditionally a season when respiratory illnesses tend to surge. With the colder months and holiday gatherings on the horizon, they urged parents, caregivers, and other at-risk individuals to ensure that their vaccinations are up to date. Pertussis is known to be especially severe in younger children and older adults, who have lower immunity or whose immunity may have waned over time, making them more vulnerable to the illness and its complications.
The CDC reiterated that vaccination remains the most effective defense against pertussis. In particular, medical experts recommended that adults, especially those who have not received a booster shot recently, get updated vaccinations. These booster shots are crucial for maintaining immunity, as immunity from the childhood vaccine can fade over time. Public health officials also emphasized the importance of early detection of pertussis symptoms, which include prolonged coughing fits, a characteristic “whooping” sound, and difficulty breathing. Identifying symptoms early helps prevent the further spread of the disease, which is critical as we approach the holiday season and the potential for increased social gatherings and travel.
The CDC’s warning underscores the risks associated with the holiday season, where people tend to congregate in larger groups. Without proper awareness and preventive measures, such as ensuring vaccinations are up to date and being vigilant for early signs of pertussis, outbreaks could escalate. In light of this, health experts are urging individuals to take proactive steps to protect themselves and those around them, particularly vulnerable populations, as the year-end surge in respiratory illnesses begins to take hold.
