“Anyone can get pertussis, though infants are at greatest risk for life-threatening illness,” Dr. Steven Stack, DPH commissioner, said in a news release. “Fortunately, vaccinations are available to help prevent serious disease.”
Whooping cough is a highly contagious respiratory illness spread by coughing and sneezing. Infected people can spread the disease from the start of symptoms and at least two weeks after coughing begins.
Early symptoms of whooping cough look like a common cold, including runny nose, sneezing, mild cough and low-grade fever. After one to two weeks, long coughing spells develop, which often occur in explosive bursts, sometimes ending with a high-pitched whoop and vomiting. This can go on for up to 10 weeks or more, according to the Centers for Disease Control and Prevention.
Babies younger than one year old are at greatest risk of getting whooping cough and having severe complications from it. And people with pre-existing health conditions that may be worsened by whooping cough are at high risk for developing a severe infection.
And because some people have mild symptoms and don't know they have it, the disease can be spread unknowingly. Many babies are infected this way, says the release.
DPH reports that this year in Kentucky, "at least eight cases have resulted in hospitalization – four infants, one school-aged child and three adults – and there have been no known deaths at this time. The majority of identified cases have occurred in school-aged children. Additional cases have been identified in infants/toddlers and adults."
The best way to prevent whooping cough is through vaccination. The childhood vaccine is called DTaP. Infants should receive a series of DTaP immunizations at 2, 4, and 6 months, with boosters at 15-18 months and 4-6 years. Children should then get a single dose of the booster, called Tdap, at 11 or 12. Boosters are required every 10 years to maintain efficacy.
In addition, pregnant women should be immunized with every pregnancy to protect their babies, says DPH.
The pertussis vaccine, which is combined with tetanus and diphtheria vaccines, is required for Kentucky school children.
