Whooping cough, also known as pertussis, is on the rise in Louisiana. This preventable illness is making a dangerous comeback.
As of mid-May 2025, 170 cases have been reported, already more than all of 2024. Tragically, two infants have died, and many more have been hospitalized.
Health officials warn that Louisiana may surpass its all-time high this year. This spike — alongside recent measles cases — is a powerful reminder that vaccine-preventable illnesses we thought were behind us can still pose serious threats, especially to the youngest among us.
Why Babies Are Most at Risk
Whooping cough is caused by a bacterium that spreads easily through coughing, sneezing and close contact. For adults, it may look like a lingering cold or cough. But for infants, it can cause dangerous breathing problems and even death.
Since September 2024, nearly 70% of whooping cough hospitalizations in Louisiana have been babies under 1 year old. Many of these infants caught the disease from well-meaning family members or caregivers who didn’t know they were contagious.
What Vaccines Protect Against Whooping Cough?
Vaccination is the most effective way to prevent the spread of pertussis. Two vaccines provide protection:
- DTaP – For children younger than 7
- Tdap – For older children, teens and adults
These vaccines also guard against tetanus and diphtheria, but their protection fades over time. That’s why booster shots are so important.
What Parents and Caregivers Can Do Now
Here’s how to protect your child and others from this dangerous illness:
- Make sure your child is current on all recommended vaccines, including DTaP.
- Teens and adults need a Tdap booster, especially if it’s been more than 10 years.
- If you’re pregnant, talk to your OB-GYN. Tdap is recommended during every pregnancy to help protect your baby.
- Anyone who spends time around a newborn — grandparents, siblings and babysitters — should also get vaccinated.
Don’t Wait Until It’s Too Late
Whooping cough spreads before people realize they’re sick. Vaccines don’t just protect you. They protect the people around you, especially those too young to be fully immunized.
