Cases of Pertussis Confirmed at Cary-Grove

Eight cases of pertussis (or whooping cough) have been confirmed at Cary-Grove High School.

According to the , the cases have been investigated and confirmed in the last 30 days at the Cary school.  All of the students are receiving antibiotics.

MCDH reported 9 cases in 2010 and 51 cases in 2009.

Pertussis is a contagious bacterial infection that causes a range of illnesses, from mild cough to severe disease. It is easily spread from person to person through coughing and sneezing.

Symptoms of pertussis may appear five to 10 days following exposure but can take up to 21 days.

The first symptoms are similar to those of a common cold — runny nose, sneezing, low-grade fever and a mild, occasional nonproductive cough. The cough gradually becomes severe and, after one to two weeks, an individual will have bursts of numerous, rapid coughs with a distinctive “whooping” sound.

According to the MCDH, while it can be mild in some persons, it poses a greater risk for infants who are not fully immunized (until 4-6 years old), immune compromised individuals and older persons.

If someone shares a household with these persons, consider getting the vaccination. If a person or their child have symptoms or questions on whether the vaccine is needed, they should contact their physician.

Persons with pertussis should be excluded from school, work or other group settings until they receive appropriate evaluation and treatment. Pertussis is a vaccine-preventable illness and easily treated with antibiotics which should also be taken by close contacts to prevent the spread of illness.

According to the MCDH, vaccinated children and adults may still become infected with and transmit pertussis, however disease is less likely to be severe. Frequent hand washing, respiratory hygiene (ie, covering the mouth, coughing into tissues, disposing of tissues properly) and staying home when ill are important practices to limit the spread of infection.

Parents should be sure to keep children up to date with recommended pertussis vaccinations; an adolescent/adult pertussis booster vaccine (Tdap) should be given to those aged 11-18 before entering high school.
