Whooping cough, also called pertussis, is a highly contagious respiratory illness that’s particularly dangerous for babies. More than 25,000 whooping cough infections have been reported in the U.S. so far in 2025, marking the second year in a row with higher than usual cases, and some states have reported multiple infant deaths from the disease. Fortunately, vaccines are extremely effective at preventing the disease across age groups.
Read on to learn about the symptoms and risks of whooping cough, who should get vaccinated, and what to do when symptoms appear.
What are the symptoms of whooping cough?
Early symptoms of whooping cough typically appear five to 10 days after exposure and may include a runny or stuffy nose, a low fever, and a mild cough. One to two weeks later, some people may experience extreme coughing fits that can cause shortness of breath, trouble sleeping, vomiting, fatigue, and rib fractures. These fits usually last one to six weeks, but they can last up to 10 weeks after infection.
About one in three babies under 1 year old who contract whooping cough require hospitalization, as they may experience life-threatening pauses in breathing (called apnea), pneumonia, and other complications. Children and adults who have asthma or are immunocompromised are also more likely to develop severe symptoms.
Which vaccines protect against whooping cough, and who is eligible?
Two types of vaccines protect against whooping cough: The DTap vaccine is given to babies and children up to 6 years old, while the Tdap vaccine is given to children 7 years and older and adults. Both vaccines protect against infections from diptheria, tetanus, and pertussis.
The American College of Obstetricians and Gynecologists recommends that pregnant people receive a single dose of the Tdap vaccine between 27 and 36 weeks of pregnancy, as this lowers the risk of whooping cough in babies younger than 2 months old.
Multiple doses are required for the best protection. Learn more about DTaP and Tdap vaccine schedules from the American Academy of Pediatrics, and talk to your health care provider about how many doses you and your children need.
What should families do when whooping cough symptoms appear?
If you or your child has symptoms of whooping cough, isolate the infected person from vulnerable family members. It’s also important to seek treatment early to reduce the risk of serious illness. Health care providers typically prescribe antibiotics to those recovering at home.
Over-the-counter cough and cold medicine is not recommended for children under 4 years old. However, limiting smoke, dust, and chemical fumes at home and using a humidifier can reduce coughing. If you are caring for someone with whooping cough who exhibits pauses in breathing or develops gray or blue skin, call 911 immediately.
