In a stark warning to public health, the Centers for Disease Control and Prevention (CDC) has reported over 25,000 cases of Whooping cough, also known as pertussis, across the United States so far in 2024. This marks the highest number in more than a decade, surpassing the 2014 peak and signaling a dangerous outbreak driven by waning vaccination rates since the COVID-19 pandemic. Tragically, at least two deaths have been confirmed in Louisiana and Washington state, both involving unvaccinated infants, underscoring the illness’s lethal threat to young children.

The surge has health officials on high alert, with cases reported in 48 states and the District of Columbia. Pediatricians and epidemiologists are calling for an urgent revival of routine vaccination campaigns, as the highly contagious bacterial infection spreads rapidly in schools, daycares, and households.
CDC Data Reveals Unprecedented Pertussis Spike Across 48 States
The CDC‘s latest weekly morbidity report, released on October 10, 2024, shows 25,357 confirmed Whooping cough cases through the end of September—more than double the 12,000 cases recorded for all of 2023. This explosive growth represents a 118% increase from the previous year, with projections suggesting the total could climb past 30,000 by year’s end if trends persist.
State-level breakdowns paint a grim picture. Pennsylvania leads with over 3,200 cases, followed by New York (2,800), California (2,500), and Ohio (2,100). Midwestern and Northeastern states are hotspots, but no region is spared. “This is the worst pertussis outbreak since 2012-2014, when we saw similar national highs,” said Dr. Shannon Stokley, a CDC epidemiologist, in a press briefing. “The data is clear: we’re in the midst of a resurgence fueled by immunity gaps.”
Symptoms of Whooping cough start mildly like a common cold but escalate to severe coughing fits, the characteristic “whoop” sound as patients gasp for air, vomiting, and exhaustion. In infants under six months—the most vulnerable group—complications include pneumonia, seizures, and apnea, with hospitalization rates exceeding 50%.
- Key CDC Stats (2024 YTD):
- 25,357 confirmed cases
- 1,200+ infant hospitalizations
- 2 fatalities (Louisiana: 2-month-old; Washington: 6-week-old)
- 48 states affected, 0 cases only in Alaska and Wyoming
Fatal Cases in Louisiana and Washington Highlight Infant Vulnerability
The deaths of two unvaccinated infants have galvanized national attention. In Louisiana, a 2-month-old from Jefferson Parish succumbed on September 15 after weeks on a ventilator. Health officials there confirmed the child had no pertussis vaccination and lived in a household with low immunization coverage. “This tragedy was preventable,” stated Louisiana Department of Health Director Dr. Ashley Wennerstrom. “Whooping cough kills when we let our guard down.”
Similarly, in Washington state, a 6-week-old from King County died on October 2. The infant’s family reported exposure to a relative with a confirmed case. Washington’s Department of Health noted 450 statewide cases this year, a 300% jump from 2023. Both fatalities align with CDC warnings that babies too young for full vaccination rely on herd immunity.
Experts emphasize that whooping cough is particularly insidious for newborns. “The DTaP vaccine series begins at 2 months, but maternal Tdap vaccination during pregnancy provides crucial protection,” explained Dr. Yvonne Maldonado, a pediatric infectious disease specialist at Stanford University. Without it, infants face a 1 in 100 mortality risk during severe infections.
Post-Pandemic Vaccination Drop Sparks Whooping Cough Resurgence
A key driver of this outbreak is the sharp decline in childhood vaccination rates, which plummeted during the COVID-19 era and have not fully recovered. CDC data shows kindergarten whooping cough vaccination coverage fell from 95% pre-pandemic to 92.7% in 2023-2024, leaving millions unprotected.
Disrupted well-child visits, school closures, and vaccine hesitancy contributed. A 2024 CDC survey found 15% of parents skipped or delayed DTaP shots due to pandemic fears. Teens, whose Tdap booster wanes after 5-10 years, are also super-spreaders—accounting for 25% of cases despite comprising just 10% of the population.
“We’ve seen this before,” noted Dr. Paul Offit, director of the Vaccine Education Center at Children’s Hospital of Philadelphia. “In 2010, California had a deadly pertussis outbreak with 10 infant deaths amid similar vaccine exemptions rising. History is repeating itself.” Nationwide, non-medical exemptions for kindergarteners hit 3% in 2023, up from 2.5% in 2019.
- Timeline of Declining Rates:
- 2019: 94.8% kindergarten coverage
- 2021: 93.3% (pandemic low)
- 2023: 92.7%
- 2024 Goal: 95% unmet
Health Experts Demand Vaccination Campaigns to Curb Outbreak
In response, the CDC and American Academy of Pediatrics (AAP) have issued emergency guidance. “Get vaccinated now—it’s not too late,” urges CDC Director Dr. Mandy Cohen. Recommendations include Tdap boosters for adults, especially pregnant women (ideally 27-36 weeks), and catch-up shots for kids.
States are ramping up efforts. Pennsylvania launched free clinic drives, vaccinating 5,000 in a week. New York mandated Tdap for middle schoolers. Pharmacies like CVS and Walgreens report a 40% uptick in pertussis vaccine requests post-CDC alerts.
Antibiotics like azithromycin treat active cases and prevent transmission if given early, but vaccination remains the cornerstone. Public health campaigns feature PSAs with coughing infants and survivor stories, aiming to combat misinformation.
Globally, the WHO reports similar whooping cough upticks in the UK (10,000 cases) and Australia, linking them to pandemic disruptions. U.S. experts fear international travel could exacerbate the domestic outbreak.
Lessons from 2014 Peak Point to Urgent National Action Ahead
Looking back, the 2014 pertussis wave—with 32,000 cases and 13 deaths—prompted vaccine reforms like cocooning (vaccinating family contacts). Today’s surge dwarfs early pandemic years but echoes that era’s vulnerabilities.
Projections from the CDC‘s modeling team warn of 40,000+ cases by 2025 without intervention, potentially straining pediatric ICUs. Winter holidays loom as a transmission risk, with indoor gatherings amplifying spread.
Optimism lies in proven tools: the DTaP/Tdap vaccines are 85-90% effective against severe disease. Community leaders, schools, and employers are urged to promote vaccination. “We can turn this around,” said AAP President Dr. Moira Szilagyi. “But it requires collective action today to protect tomorrow’s children.” Federal funding for back-to-school shots and maternal programs could blunt the curve, with lawmakers eyeing bills for expanded access.
As flu season overlaps, co-infections pose added dangers. Health departments advise masking for coughers, hand hygiene, and staying home. Monitoring tools like the CDC‘s Respiratory Illnesses Data Channel provide real-time tracking, empowering proactive measures.
The path forward hinges on rebuilding immunity walls eroded by the pandemic. With swift vaccination drives and awareness, the U.S. can avert a full-blown crisis and safeguard its youngest from this preventable killer.
