CDC Reports Sharp Increase in Whooping Cough Cases Nationwide and in the Delaware Valley
Whooping Cough: Symptoms, Causes, Treatment, and Prevention
- Whooping cough, also known as pertussis, is a highly contagious respiratory disease caused by the Bordetella pertussis bacteria. It primarily affects infants and young children, but adults and adolescents can also contract the illness. Despite being preventable through vaccination, whooping cough remains a global health concern, with periodic outbreaks occurring in different regions.
Symptoms of Whooping Cough
- Whooping cough symptoms typically develop within 5 to 10 days after exposure but may take as long as three weeks to appear. The disease progresses through three stages, with symptoms varying as it advances: Catarrhal Stage (1-2 weeks):
A- Symptoms resemble a common cold, including a runny nose, mild cough, sneezing, low-grade fever, and watery eyes.
B- This is the most contagious stage of the illness. Paroxysmal Stage (1-6 weeks):
A- The hallmark of whooping cough is violent, rapid coughing fits (paroxysms), often followed by a high-pitched "whoop" sound when breathing in.
B- The cough can cause vomiting, exhaustion, and difficulty breathing, especially in infants.
C- The episodes are more frequent at night and can last several weeks, making it difficult for affected individuals to eat, drink, or sleep. Convalescent Stage (2-6 weeks or longer):
A- The recovery phase begins, with the cough gradually becoming less severe.
B- Even though the paroxysms diminish, some individuals may continue coughing for weeks to months.
- Because whooping cough is so contagious, outbreaks can occur even in well-vaccinated populations, although the illness is generally less severe in those who have been vaccinated.
A- Pneumonia: The most common complication, especially in infants.
B- Seizures: Caused by a lack of oxygen during severe coughing fits.
C- Apnea: A temporary pause in breathing, particularly in infants.
D- Weight loss: Due to difficulty eating and vomiting after coughing fits.
- In adults, complications tend to be less severe but can include rib fractures from intense coughing and secondary infections.
Supportive care is equally important and may involve:
A- Hydration: Ensuring that the patient drinks plenty of fluids to prevent dehydration.
B- Rest: Adequate rest is essential, particularly during the paroxysmal phase.
C- Humidified air: Using a humidifier can help soothe the respiratory tract and ease breathing.
- In severe cases, especially with infants, hospitalization may be necessary to monitor breathing, provide oxygen therapy, and administer intravenous fluids.
A- DTaP Vaccine: Administered to infants and young children, this vaccine provides protection against diphtheria, tetanus, and pertussis. It is given in a series of doses at 2, 4, 6, and 15-18 months of age, followed by a booster at 4-6 years.
B- Tdap Vaccine: This booster vaccine is recommended for adolescents and adults, particularly pregnant women during the third trimester. It provides continued protection against whooping cough and helps protect newborns who are too young to be vaccinated.
- Whooping cough remains a preventable but potentially serious disease, particularly for infants and young children. Awareness of its symptoms and the importance of vaccination are crucial for preventing outbreaks and protecting vulnerable populations. Maintaining high vaccination rates and recognizing early signs of infection are key strategies in controlling the spread of whooping cough worldwide.

Causes and Transmission
- Whooping cough is caused by the bacterium Bordetella pertussis, which releases toxins that damage the airways and cause inflammation. The disease spreads through respiratory droplets when an infected person coughs or sneezes. Close contact with an infected individual greatly increases the risk of transmission.- Because whooping cough is so contagious, outbreaks can occur even in well-vaccinated populations, although the illness is generally less severe in those who have been vaccinated.
Complications
- Whooping cough can lead to serious complications, particularly in infants and young children, who are at greater risk of hospitalization and death. Complications include:A- Pneumonia: The most common complication, especially in infants.
B- Seizures: Caused by a lack of oxygen during severe coughing fits.
C- Apnea: A temporary pause in breathing, particularly in infants.
D- Weight loss: Due to difficulty eating and vomiting after coughing fits.
- In adults, complications tend to be less severe but can include rib fractures from intense coughing and secondary infections.
Treatment of Whooping Cough
- The primary treatment for whooping cough involves antibiotics, which can help to reduce the duration of the illness if administered early and minimize the risk of spreading the disease. Common antibiotics used include azithromycin, clarithromycin, and erythromycin.Supportive care is equally important and may involve:
A- Hydration: Ensuring that the patient drinks plenty of fluids to prevent dehydration.
B- Rest: Adequate rest is essential, particularly during the paroxysmal phase.
C- Humidified air: Using a humidifier can help soothe the respiratory tract and ease breathing.
- In severe cases, especially with infants, hospitalization may be necessary to monitor breathing, provide oxygen therapy, and administer intravenous fluids.
Prevention of Whooping Cough
- The most effective way to prevent whooping cough is through vaccination. Two types of vaccines are commonly used:A- DTaP Vaccine: Administered to infants and young children, this vaccine provides protection against diphtheria, tetanus, and pertussis. It is given in a series of doses at 2, 4, 6, and 15-18 months of age, followed by a booster at 4-6 years.
B- Tdap Vaccine: This booster vaccine is recommended for adolescents and adults, particularly pregnant women during the third trimester. It provides continued protection against whooping cough and helps protect newborns who are too young to be vaccinated.
Why Vaccination is Key
- Although vaccination does not provide lifelong immunity, it significantly reduces the risk of contracting and spreading the disease. Even in cases where vaccinated individuals contract pertussis, the illness tends to be milder and less likely to result in severe complications.- Whooping cough remains a preventable but potentially serious disease, particularly for infants and young children. Awareness of its symptoms and the importance of vaccination are crucial for preventing outbreaks and protecting vulnerable populations. Maintaining high vaccination rates and recognizing early signs of infection are key strategies in controlling the spread of whooping cough worldwide.
Whooping Cough Cases Surge Across the U.S. and Delaware Valley, CDC Reports
- PHILADELPHIA (WPVI) — According to a new report from the Centers for Disease Control and Prevention (CDC), the number of confirmed whooping cough cases nationwide is five times higher compared to this time last year.
- The rise is even more pronounced in Pennsylvania and Delaware.
- The rise is even more pronounced in Pennsylvania and Delaware.
- “We're definitely seeing a significant year for whooping cough, and it's important to take the necessary precautions," said Lora Werner, interim director of the Delaware County Health Department.
Werner has witnessed the growing number of cases and their impact firsthand.
- “About half of the infants diagnosed with whooping cough and under one year of age end up hospitalized,” she explained.
- So far this year, Delaware County has reported 182 confirmed cases, a sharp increase from just one case at the same time last year.
- “We’ve been sending alerts to the medical community through the medical society,” Werner added.
- The CDC's latest data shows a nationwide rise in whooping cough cases, jumping from 3,260 at this time in 2023 to 17,579 this year—an increase of five times.
- Locally, the numbers are even more alarming. Data shows that Pennsylvania has seen 10 times more cases than last year. New Jersey has 2.6 times more cases, while Delaware's count has surged by 17 times.
- Experts attribute the increase to a return to pre-pandemic conditions. During COVID-19, social distancing and isolation helped limit the spread of highly contagious diseases like whooping cough. Now that life has returned to normal, the cases are rising again.
- This resurgence has prompted renewed efforts to promote vaccination, particularly for children and adults. Whooping cough vaccines are part of the T-DAP series for children, with four doses administered during early childhood.
“We also recommend that pregnant women get the vaccine during each pregnancy,” Werner said.
Adults are encouraged to receive booster shots every 10 years. As whooping cough cases continue to climb, public health officials are focusing on educating the community about prevention and vaccination.
“Washing hands and staying home when sick—those practices are still effective,” Werner emphasized.
