Pertussis (Whooping Cough)
What is pertussis?
Pertussis or whooping cough is a contagious disease of the respiratory tract (airways and lungs). It is caused by bacteria found in the mouth, nose and throat of an infected person. Pertussis can be a serious, even life-threatening illness in infants less than 12 months old. Pertussis is spread through direct contact with nose and throat mucus and droplets. After exposure, illness usually begins between one to three weeks later.
Prescription antibiotics can decrease the spread of pertussis. If your child is diagnosed with pertussis, he or she will be asked to remain home from school for five days so that the antibiotics can take effect.
Pertussis starts with cold-like symptoms, which are followed in one to two weeks by a severe cough that can last for weeks to months. During coughing attacks, children may gag, gasp or strain to inhale, sometimes making the high-pitched whooping sound. This may be followed by vomiting or exhaustion. Usually, there is no fever or only a mild fever.
- Immunization is the most effective way to prevent the spread of this illness. It is still possible to get sick with pertussis if you have had all the necessary vaccines, but the risk of infection is much greater in those who are not up to date on pertussis vaccines.
- Now is a good time to review your child’s immunization record to see if he or she is current on all vaccinations.
- Frequently wash hands with soap and water.
- Cover coughs and sneezes.
Washington County Public Health recommends the following:
- If your child has symptoms of pertussis, keep him or her at home and consult with their health care provider.
- If your child is diagnosed with pertussis, please report this to the regional pertussis program at 503-988-8848.
- Review and update (if necessary) your child’s immunization record. Current recommendations for pertussis vaccination are as follows:
- Five-dose series of DTaP (diphtheria, tetanus, and acellular pertussis) through age six. These doses are typically given at age 2 months, 4 months, 6 months, 15-18 months, and 4-6 years.
- All adolescents aged 11-12 years should receive one dose of Tdap (tetanus, diphtheria, and acellular pertussis) vaccine.
- Those ages 11–64 years old who have not yet received the Tdap vaccine should get it now.
- Children ages seven to 10 years of age who are not fully vaccinated against pertussis should receive a dose of Tdap vaccine.
- Adults over age 65 and pregnant women should consult with their health care provider about getting the Tdap vaccine.
- Anyone who has not gotten the vaccine series on time should consult with their health care provider on how to catch up.
