Abstract :

Back ground and Objective: Pertussis is a major cause of morbidity and mortality in infants and children worldwide in spite of the availability of a good protected vaccine. The incidence or prevalence rate among children or adults in Yemen are unknown. To determine the level of IgG antibodies of Bordetella pertussis. Methods: Blood samples were collected from participated military recruits and commercially available Enzyme-linked Immunosorbent Assay was used. Cross-sectional study was conducted on 188 military recruits, between March and October 2013.Results: The prevalence of B. pertussis protective rate among different age groups of military recruits was 92.6%. The highest rate of antibodies 100% was among age group below 20 years followed with 96.3% for >35 years and the lowest protective rate was 89.5%o for age group 25-29 years old. 92.9% protective rate for age group 30-34 years. While the seronegative rate was 7.4% among all age group. Meanwhile, the levels of B. pertussis IgG antibodies were 38.8% who had IgG antibodies level between 1.51-1.99 IU/ml. Conclusions. The findings of this study concluded that the Yemeni military recruits were not enough immunized to pertussis and with confirmed of low awareness about vaccination and medical history related to pertussis infection particularly among this high-risk of Yemeni community, therefore the routine a cellular booster vaccination of adults is a key way to indirectly protect infants and community.
