Surge in Whooping Cough Cases Highlights Need for Vigilance and Vaccination
Whooping cough, also known as pertussis, is seeing a significant resurgence across the United States and other parts of the world. With nearly 27,000 cases reported in 2024, the Centers for Disease Control and Prevention (CDC) notes this as the highest incidence since 2012. Experts are urging the public to remain proactive, especially as winter approaches and respiratory illnesses tend to spike.
The Disease and Its Risks
Whooping cough is caused by the Bordetella pertussis bacteria and is highly contagious. It spreads through respiratory droplets when an infected person coughs, sneezes, or talks. The illness often begins with mild cold-like symptoms, but it quickly progresses to severe coughing fits that can last weeks or months. The hallmark “whooping” sound when gasping for air is more common in children but can be absent in adults.
The disease poses the greatest threat to infants under one year old, as they are at the highest risk for severe complications, including pneumonia, brain damage, and death. However, it also affects adults and teens, who often unknowingly spread the bacteria to vulnerable populations, particularly babies.
Vaccine Effectiveness and Challenges
Vaccines have been pivotal in reducing the severity and mortality of pertussis. The current vaccines, however, are not without limitations. Protection wanes over time, leaving individuals vulnerable years after their last dose.
A research director at the French National Institute of Health and Medical Research, explains that modern acellular pertussis vaccines, while safer than earlier whole-cell vaccines, might lack long-term effectiveness. They are based on fewer antigens, which could result in a less robust immune response. This waning immunity contributes to the cyclical nature of pertussis outbreaks.
Current Surge: Causes and Concerns
The rise in cases can partly be attributed to the relaxation of COVID-19 precautions, such as social distancing and mask-wearing, which had suppressed the spread of many infectious diseases. Additionally, vaccine hesitancy has become a growing concern. Suresh Nagappan, a pediatric medical director in North Carolina, notes that declining trust in public health authorities has made it harder to achieve high vaccination rates.
Pregnant women are a critical focus group for vaccination. Immunization during pregnancy protects both the mother and the newborn, who cannot receive their first pertussis shot until two months of age. However, vaccination rates among pregnant women have declined in recent years, further exposing infants to risk.
Regional Insights
Montana, North Carolina, and Ohio are among the states seeing localized spikes in pertussis cases. Yellowstone County, Montana, has reported 11 cases this year, with six occurring in November alone. Meanwhile, North Carolina officials warn that the return to pre-pandemic social behaviors is fueling the spread.
In Toledo, Ohio, pediatricians are emphasizing the importance of booster shots for adults, particularly those in contact with infants or pregnant women. The CDC recommends a pertussis-containing booster every 10 years for adults.
Prevention and Proactive Measures
Experts unanimously stress the importance of vaccination as the most effective tool to combat pertussis. “Nobody gets lifetime protection from either the vaccine or the illness,” notes an Ohio pediatrician, reminding adults to stay current on their shots. Pregnant women, in particular, should prioritize getting vaccinated during the third trimester to pass antibodies to their unborn babies.
In addition to vaccination, early diagnosis and treatment with antibiotics can limit the severity and duration of the illness. However, antibiotics are most effective before severe coughing fits begin.
Looking Ahead
While the current surge in whooping cough cases is concerning, public health experts remain optimistic about controlling its spread. Enhanced awareness, vaccination efforts, and timely medical interventions can mitigate the impact of this preventable disease. As Juliet Lautenbach, a whooping cough survivor and mother, puts it, “The vaccine may not be perfect, but it likely saved my daughter’s life.”
