Pertussis, or "whooping cough" is on the rise across the country, and the state of Alabama has seen over 150 cases so far this year.
The highly contagious disease is preventable with vaccines. However, children and infants who have not received vaccinations for the disease are at high risk of infection.
Dr. Karen Landers is a medical consultant for Alabama's immunization program. She says whooping cough has been around for many years and is caused by a bacterium called Bordetella pertussis.
