Whooping Cough (Pertussis)
Whooping cough (pertussis) is a reportable disease in Oklahoma. Whooping cough is a respiratory disease caused by the bacteria Bordetella pertussis. The disease is characterized by spasms of severe coughing (paroxysms). Coughing fits are continuous making it difficult for the person to catch their breath until the end of the fit. These coughing fits are often followed by the characteristic inspiratory whoop and/or coughing so hard that the person vomits.
Illness onset is subtle, with symptoms similar to those of a minor upper respiratory infection. There are three stages of whooping cough. The first is called the catarrhal stage, occurring in the first 1 to 2 weeks of illness. Symptoms people have during the catarrhal stage include a runny nose, dry cough and no fever. Frequently lasting for several weeks, the paroxysmal stage (second stage) occurs when symptoms progress to episodes of coughing fits. The disease peaks in severity after 1 or more weeks of coughing fits. The third stage is the convalescent stage where symptoms begin to slowly taper. The convalescent stage often lasts 2 to 6 weeks but in some cases, it may last up to 3 months. In adults, adolescents, and vaccinated children, whooping cough often can present as a chronic cough. In very young infants, the whoop is often absent and apnea is common.
Whooping cough is spread from one person to another when respiratory droplets are expelled from the nose or throat of an infected person through coughing or sneezing, and then inhaled by another person. It is spread to those who have prolonged close contact with an infected person, such as household members. In most cases, school classmates, co-workers, and people in clinic waiting rooms are not considered at risk. The period of time between exposure and symptom onset range from four to 21 days. Without treatment, an infected person can spread the disease from the time he or she starts coughing up to three weeks after symptom onset. After five days of treatment an appropriate antibiotic, an infected person cannot spread the disease.
Cases of whooping cough reported to the Oklahoma State Department of Health are investigated to identify exposed household, close, and direct face-to-face contacts as well as those with direct contact with nasal or throat secretions to recommend a preventive course of antibiotics in order to prevent the development of whooping cough in contacts.
Anyone can get whooping cough, but it is more common among infants and young children. In recent years, whooping cough has become more common in adolescents and adults who have lost the protection they got from vaccination or illness in childhood.

The best way to prevent yourself and your family from whooping cough is to get the whooping cough (pertussis) vaccine. Two vaccines are available to protect against whooping cough. The childhood vaccine is called DTaP (diphtheria, tetanus, and pertussis) and is given to children at 2 months, 4 months, 6 months, 12-15 months of age, and a booster between 4 and 6 years of age. The adult and adolescent vaccine is called Tdap (tetanus, diphtheria, and pertussis), and should replace one dose of the Td booster (tetanus-diphtheria) after the childhood series. Talk with your healthcare provider or local health department if you have other questions about the vaccines.
If you believe you have whooping cough (pertussis), contact your healthcare provider. Antibiotics are used to treat whooping cough. Treatment may make your illness less severe if it is started early. Treatment after three weeks of illness is unlikely to help because the bacteria are gone from your body, even though you may still have a cough. Once a person is treated for whooping cough, they can no longer spread the bacteria. Other therapies such as fluids, oxygen, and mild sedation may help a child during periods of severe coughing.
