Introduction: The Silent Comeback of an Old Threat
Since the COVID-19 pandemic disrupted healthcare systems worldwide, a silent but dangerous trend has emerged—a significant drop in routine childhood vaccination rates, including those for whooping cough, or pertussis. According to a revealing ProPublica analysis, more parents are delaying or skipping their children's vaccines altogether. While the consequences may not be immediately visible, this shift has created a dangerous vulnerability in our communities.
Whooping cough, once thought to be largely under control thanks to widespread immunization efforts, is now making an unsettling comeback. This highly contagious respiratory disease can be especially severe—even deadly—for infants and young children. And yet, it's quietly regaining ground, aided by lower vaccination coverage and growing misinformation around vaccine safety.
We often think of diseases like pertussis as part of history, but they’re not gone—they’ve just been kept at bay by modern medicine. Whooping cough is not a thing of the past. It's here, lurking, and it’s knocking on our doors once again. This time, we must answer—not with fear, but with awareness, prevention, and action. Protecting our children means understanding the risks and recommitting to the power of vaccines.
What Is Whooping Cough?
Whooping cough, medically known as pertussis, is a highly contagious respiratory infection caused by the Bordetella pertussis bacterium. It often starts off quietly—much like a common cold—but quickly escalates into severe coughing fits that can last for weeks or even months. This illness is especially dangerous for infants and young children, whose small airways make them more vulnerable to complications.
In its early stages (typically within the first 1–2 weeks), pertussis may show mild, cold-like symptoms such as a runny or stuffy nose, low-grade fever, watery eyes, and a dry cough. These signs can be easy to overlook, making early detection challenging.
However, as the infection progresses (weeks 2–6 and beyond), the coughing becomes more intense. Individuals may experience violent fits of coughing that end with a telltale "whooping" sound when gasping for breath. Other symptoms include vomiting after coughing, fatigue, and—in serious cases, especially in infants—pauses in breathing (apnea).
Dr. Amanda Smith, a pediatric pulmonologist at Mayo Clinic, explains it best:
“It starts like a whisper and ends like a scream.”
Understanding the early warning signs and getting prompt medical care can help prevent serious complications—and protect vulnerable loved ones.
Why Pertussis Is Making a Comeback
Whooping cough, or pertussis, is a highly contagious respiratory disease that we once had under control. So why is it making a comeback in 2025? Here’s what’s driving the resurgence:
1. Drop in Vaccination Rates
After 2020, vaccination rates fell significantly across the U.S., according to the CDC. Several factors contributed:
- Misinformation: Online myths and conspiracy theories caused many to question vaccine safety.
- Healthcare disruptions: The COVID-19 pandemic led to missed routine appointments.
- Vaccine hesitancy: Public trust in health institutions took a hit, leading many to skip even established vaccines.
2. Waning Immunity
Unlike some vaccines that provide lifelong protection, the pertussis vaccine requires boosters. Over time, immunity fades, and without updated shots, even vaccinated individuals are at risk.
3. Undetected Community Spread
Pertussis often starts with cold-like symptoms—runny nose, mild cough, low fever—so people don’t realize they’re infectious. This leads to unintentional spreading, especially in schools and crowded areas.
As pertussis cases climb, it’s a reminder that vaccine-preventable diseases can resurface when vigilance fades. Staying informed and up-to-date on immunizations is key to protecting communities.
How Whooping Cough Spreads: What You Need to Know
Imagine the flu—but worse. Whooping cough, or pertussis, is a highly contagious bacterial infection that spreads like wildfire, especially in crowded places. It’s most contagious during the first two weeks, often before any noticeable symptoms appear, which makes early transmission hard to control.
Here’s how it spreads:
- Coughing or sneezing: Tiny droplets carrying the bacteria get into the air and are inhaled by others nearby.
- Close contact: Hugging, kissing, or simply being near someone infected can pass the bacteria along.
- Sharing utensils or drinks: The bacteria can transfer easily through saliva.
- Contaminated surfaces: Respiratory droplets can linger on objects like doorknobs, toys, or phones.
According to the Cleveland Clinic, one infected person can spread pertussis to up to 15 people, especially in settings like schools, daycare centers, or family gatherings.
Young children, infants, and people with weakened immune systems are especially vulnerable. Because early symptoms resemble a mild cold, many people don’t realize they’re contagious until it's too late. That’s why vaccination and early diagnosis are key in preventing outbreaks.
On The Vaccine: How It Works and Why It’s Vital
Vaccines like DTaP and Tdap are essential tools in protecting us from serious diseases: diphtheria, tetanus, and pertussis (whooping cough). They train your immune system to recognize and fight off these threats before you ever encounter them. Here’s why they matter and when to get them:
Vaccine Schedule
- DTaP: Given in a 5-dose series, starting at 2 months of age, continuing through early childhood.
CDC Vaccine Schedule for Ages 0–6 - Tdap: A booster at age 11, then every 10 years into adulthood.
CDC Vaccine Schedule for Ages 7–18
Why It’s Vital
- Community Protection: Keeps vulnerable groups safe, including infants and the elderly.
- Stops Outbreaks: Prevents the resurgence of diseases once thought rare.
- Pregnancy Immunity: A Tdap shot during each pregnancy passes vital antibodies to the baby, offering protection until their first vaccinations.
CDC Pregnancy Guidelines
Staying on schedule with DTaP and Tdap vaccines is a simple but powerful way to protect your family and your community.
Treatment and Complications
Treatment and Complications of Whooping Cough
Early treatment with antibiotics is key to controlling whooping cough (pertussis). When started soon after symptoms appear, antibiotics can prevent the infection from spreading to others. However, once the classic symptoms—like severe coughing fits—are in full swing, antibiotics are less effective at easing those symptoms. Still, they are often prescribed to protect close contacts and reduce transmission risk.
Serious Complications in Infants
Whooping cough can be life-threatening, especially for babies under one year old. According to the CDC:
- Apnea (pauses in breathing) is common and dangerous.
- Pneumonia is a frequent complication that can be severe.
- Seizures may occur due to low oxygen levels or infection.
- Brain damage can result from prolonged lack of oxygen.
- Tragically, about 1 in 100 infants with whooping cough may die from it.
Hospitalization Rates
Due to the severity of symptoms, about 1 in 3 infants with whooping cough require hospitalization for monitoring and intensive care. Early medical attention is critical to reduce risks and improve outcomes.
Stories from the Frontlines
Stories from the Frontlines: Case Study – Liam, 6 Months Old
At just 6 months old, Liam was too young to have completed the full DTaP (diphtheria, tetanus, and pertussis) vaccine series. Like many infants, he was vulnerable—and unfortunately, that vulnerability became a reality. While attending daycare, Liam was exposed to pertussis, commonly known as whooping cough. Within days, his condition deteriorated rapidly.
Liam’s mother, Rebecca L., recalls the terrifying ordeal of rushing him to the emergency room, where doctors quickly admitted him to the ICU. “I never imagined a cough could nearly take my child’s life,” she says. For days, Liam required oxygen support, IV fluids, and round-the-clock care to stabilize his breathing and prevent further complications.
Rebecca now speaks out as a passionate vaccine advocate. “If more people were vaccinated, maybe Liam wouldn’t have been exposed. We were doing everything right, but he was still at risk,” she explains.
Liam’s story highlights the importance of community immunity—vaccinating those who can to protect those who can’t. These stories from the frontlines remind us that vaccine-preventable diseases are still real threats. Protecting our youngest and most vulnerable starts with proactive vaccination and public awareness.

Expert Insights
Expert Insights: Dr. Nina Patel on Vaccine Delays and Infant Risk
Infectious disease expert Dr. Nina Patel from Johns Hopkins University is raising the alarm about a troubling trend: delayed childhood vaccinations. “We are seeing a trend we feared—delayed vaccination is leaving infants exposed,” Dr. Patel warns. “Vaccines aren't just personal protection; they’re public armor.” Her message is clear—vaccines protect not only the individual but also the broader community, especially the most vulnerable like infants and immunocompromised individuals.
With the rise of vaccine hesitancy and misinformation, some parents are choosing to delay or skip essential immunizations. This opens the door for once-controlled diseases like pertussis (whooping cough) to return. Pertussis is highly contagious and especially dangerous for infants. According to the World Health Organization, pertussis causes approximately 160,000 deaths each year, primarily in areas with low vaccination rates.
Delaying vaccinations doesn't just risk a child’s health—it weakens community immunity and increases the chances of outbreaks. Dr. Patel urges parents to follow the recommended immunization schedule to keep their children—and others—safe. Protecting public health starts with individual action. Timely vaccination is not just a choice—it's a responsibility.
