Whooping cough, also known as pertussis, is a highly contagious respiratory illness that has seen an alarming resurgence recently. Cases of this disease in the United States have risen dramatically; tragically, two infants in Louisiana have died of the disease this year.
This is a stark reminder that even diseases widely regarded as under control can rebound, posing a significant public health threat in our communities — especially to the youngest and most vulnerable. Whooping cough is a vaccine-preventable disease, so receiving an immunization is the best way to prevent further spread.
What is Whooping Cough?
Whooping cough is caused by a type of bacteria called Bordetella pertussis. The illness typically starts with mild, cold-like symptoms such as a runny nose, sneezing, and a mild cough. After one to two weeks, the most serious symptom emerges: severe, rapid coughing fits that produce a high-pitched “whoop” sound as the person struggles to breathe.
This disease is particularly dangerous to infants and young children. Since their airways are smaller, coughing fits can lead to serious complications including pneumonia, apnea (dangerous pauses in breathing), seizures, and even brain damage or death.
Whooping caught can persist for several weeks or even months, earning it the nickname “the 100-day cough.” Even when the intense coughing subsides, individuals can remain contagious for several weeks and potentially spread the disease to others.
The Importance of Vaccination
To protect against whooping cough, it is recommended that children receive either a DTaP or Tdap immunization. These are combination vaccines that also provide protection against diphtheria and tetanus. By exposing the body to harmless components of the pertussis bacteria, the vaccine helps the body develop antibodies to recognize and fight the bacteria if someone is exposed to it.
DTaP vaccines are given to children under the age of seven. They are administered as a series of four doses, starting at two months old and lasting until 15-18 months old. A booster dose is given between the age of four and six.
Booster Shots
The effectiveness of childhood DTaP vaccines wanes over time, though they still guard against serious illness caused by whooping cough. Tdap is a vaccine given to older children and adults who have not previously been vaccinated. The Centers for Disease Control recommend that adults receive a Tdap dose if they have not been vaccinated against whooping cough, and that they get a booster every 10 years.
Booster shots are also recommended for adults who will be in close contact with infants, who are more vulnerable to whooping cough. Pregnant women are strongly advised to receive a dose of Tdap during their pregnancy, ideally between 27 and 36 weeks gestation, to pass protective antibodies on to their newborns.
Consult with your healthcare provider to ensure you and your family are up-to-date on your whooping cough vaccinations.
