Increasing Cases Of Whooping Cough Reported In North Dakota
The North Dakota Department of Health today reported an increasing
number of pertussis (whooping cough) cases in the state. As a result, the Department of Health is
urging parents and caregivers to make sure their children are vaccinated, according to Abbi
Pierce, Immunization Surveillance coordinator.
Since Nov. 25, 2008, 11 new cases of pertussis in eastern North Dakota have been reported to the
Department of Health. Minnesota and South Dakota also are experiencing increased cases.
The number of pertussis cases usually peaks every three to five years. The most recent peak in
North Dakota was in 2004, when 757 cases were reported. North Dakota saw 168 cases in 2005,
43 cases in 2006 and 14 cases in 2007.
The total to date for 2008 is 17 confirmed cases and three probable cases of pertussis. Almost 60
percent of the confirmed cases this year are unvaccinated children or children behind on their
pertussis-containing vaccinations.
“Pertussis outbreaks highlight the importance of vaccination,” Pierce said. “Not only should
infants and children be vaccinated against pertussis; adults and adolescents need to be
vaccinated, as well, to make sure they don’t pass the disease to children who are too young to
receive the vaccine.”
Whooping cough (pertussis) is a contagious disease that lasts for many weeks or months and can
cause severe coughing with a “whooping” sound or coughing that leads to vomiting. The disease
can be life-threatening for infants and is usually spread from adults to infants. Generally, the
illness is less severe in those who are vaccinated.
Pertussis is characterized by one or more of the following symptoms:
- Prolonged cough.
- Long spells of coughing with spasms.
- Coughing with a whooping sound.
- Coughing that leads to gagging or vomiting.
People who have any of the above symptoms should contact their health-care provider to be
evaluated for whooping cough. Anyone who does not have a cough does not need to be tested.
Individuals who think they have been exposed to a pertussis case should contact their health- care
provider as soon as possible to find out if they should be put on antibiotics.
One of the most important ways to prevent the disease is vaccination. Diphtheria, tetanus and
acellular pertussis vaccine (DTaP) should be administered routinely to infants at 2, 4, 6 and 15 to
18 months of age, and a booster dose of DTaP should be given at ages 4 to 6. DTaP is required to
attend school or day care.
Tetanus, diphtheria, and acellular pertussis vaccine (Tdap) is routinely recommended for
adolescents ages 11 and 12 and is required for all adolescents entering middle school. Tdap also
is recommended for adolescents ages 13 to 18 and adults.
In an effort to protect infants from pertussis, the North Dakota Department of Health provides
Tdap vaccine for new parents or guardians, child-care providers, and fathers-to-be. Vaccinating
adults may reduce the risk of transmission to infants and other susceptible people. For more
information about where to receive the vaccine, individuals should contact their health-care
provider or local public health unit.
