Highly contagious respiratory disease. Caused by the bacterium bordetella pertussis. One positive case in a home = a 90% to 100% chance other susceptible household members will catch it! Uncontrollable, violent coughing Deep breathes after coughing “fits” result in a "whooping" sound. A bacteria releases toxins in the lungs damages the cilia and causes inflammation (swelling). Usually spread by coughing or sneezing Infants typically infected by older siblings, parents or caregivers Many adults think they just have a lingering cough from a “cold” Usually develop within 7–10 days after exposure, May be as long as 6 weeks!! Early symptoms can last for 1 to 2 weeks and usually include: Runny nose Low-grade fever (generally minimal throughout the course of the disease) Mild, occasional cough Apnea — a pause in breathing (in infants) Most Infectious during this time!! Antibiotics may shorten the time of infectivity. Paroxysms (fits) of many, rapid coughs followed by a high-pitched "whoop" Vomiting (throwing up) Exhaustion (very tired) after coughing fits Nasopharyngeal Swab: Small swab placed in nose Known as the “100 Day Cough” Serious illness in children AND adults May be life threatening in infants Worldwide: 30-50 Million cases of Pertussis and about 300,000 deaths annually More than half of infants less than 1 year of age are hospitalized. Vaccination: Prevents the spread Lessens the severity Childhood vaccine wanes over time, after 5-10 years. 57% must be hospitalized 1 in 4 (23%) get pneumonia (lung infection) 1 or 2 in 100 (1.6%) will have convulsions (violent, uncontrolled shaking) Two thirds (67%) will have apnea (slowed or stopped breathing) 1 in 300 (0.4%) will have encephalopathy (disease of the brain) 1 or 2 in 100 (1.6%) WILL DIE Washington State – Current Epidemic Approximately 2,900 cases this year Typically less than 2oo/yr North Carolina December to June - 179 cases, in 23 counties Alamance County - 122 cases alone! 126 cases reported statewide in 2011. Infant with Pertussis: VACCINATION with Tdap!! Two or more weeks before coming into close contact with an infant Families with and caregivers of new infants. Keep infants and high risk individuals away from those who are infected. Any child 7–10 who did not complete the childhood DTaP vaccination series Anyone 11 and older who has not yet received a Tdap booster Adults should get a Tdap vaccine instead of the regular tetanus booster Women who are pregnant (3rd Trimester) or may become pregnant DTaP series is recommended for children: 2 months 4 months 6 months 15-18 months 4-6 years of age Tdap booster should be given to children by 11 years of age Thank You!
