Whooping Cough Rising in Michigan, Infants at Greatest Risk
Confirmed cases of whooping cough are up in Michigan. Infants younger than 12 months are at greatest risk.
“Pertussis is a contagious disease that easily spreads between people and can be difficult to diagnose,” said Dr. Eden Wells, chief medical executive for the MDHHS. “We support the proactive efforts of the Oakland County Health Division in ensuring residents are aware of this increase and the steps they can take to protect themselves and their children.”
Anyone exposed to pertussis and displaying symptoms should be evaluated by a doctor to determine if antibiotics are needed. Infants and children who have not been fully vaccinated against pertussis are at a higher risk of developing severe illness. To be fully immunized, doses are given at 2, 4, 6, and 15 months. The last dose is given at 4 years old.
Pertussis is a very contagious disease that usually starts with cold-like symptoms and maybe a mild cough or fever. After 1 to 2 weeks, severe coughing can begin. Pertussis can cause violent and rapid coughing, over and over, until the air is gone from the lungs and people are forced to inhale with a loud "whooping" sound. In infants, the cough can be minimal or not even there. Other symptoms include:
- Runny nose
- Nasal congestion
- Red, watery eyes
- Mild fever
- Dry cough
- Vomiting after coughing fits
People infected with pertussis can spread the disease by coughing or sneezing in close contact with others who breathe in the bacteria. Pertussis is most contagious during the first two weeks of illness.
Infants are at highest risk of severe disease and death. Older siblings and adults often are the source.
All whooping cough vaccination doses should be given as close to the recommended ages as possible. A pertussis vaccine booster dose (Tdap) is recommended for adolescents and adults, and is especially important for those in contact with infants.
Current recommendations call for a single lifetime Tdap booster dose with this exception: a dose of Tdap is recommended for those pregnant in each pregnancy between weeks 27 and 36.
