|Pertussis Vaccine Protection Wanes 42% Every Year
The odds of acquiring pertussis increase 42% every year after children receive the fifth dose of the diphtheria-tetanus-acellular pertussis (DTaP) vaccine, leading to increasing outbreaks of whooping cough in immunized children, according to a study published in the September 13 issue of the New England Journal of Medicine.

|Pertussis: An Old Enemy Resurfaces
||The Association for Professionals in Infection Control and Epidemiology (APIC) reminds healthcare professionals and healthcare consumers that pertussis, commonly known as whooping cough, is a serious respiratory illness characterized by an infectious cough. Although most of us were vaccinated against it as children, our ability to fight it off weakens, leaving us once again susceptible as adults. Pertussis is very contagious and can be quite serious, especially for infants less than one year of age.
|MMWR: Local Health Department Costs Associated with Response to a School-Based Pertussis Outbreak --- Omaha, Nebraska, September--November 2008
||This report describes the results of that analysis, which indicated that 1) staff members reported 1,032 person-hours spent responding to the outbreak, and 2) the total cost of outbreak response, including overhead, labor, travel, and other costs, was $52,131 (measured in 2008 U.S. dollars). The majority of costs (59%) occurred during an intensive 10-day period, when most of the contact tracing and prophylaxis recommendations were made. The elevated incidence of pertussis and the burden of response placed on health departments warrants exploring the impact of alternative response and chemoprophylaxis strategies.
