About this study

Official title: Bordetella Pertussis Infection Among Adolescents and Adults With Prolonged Cough

This study aims to determine the burden of pertussis infection among adolescents and adults with prolonged cough in four Asian countries, namely Malaysia, Philippines, Taiwan and Thailand. This study also aims to assess the health economic (HE) impact of pertussis.

Read the detailed description

Data from this cross-sectional study will be useful in reviewing the need for introduction of booster doses of pertussis vaccines in adolescent and adult population in Malaysia, Philippines, Taiwan and Thailand.

This study will enrol patients with prolonged cough of 2 weeks or more and detect pertussis with serological tests in order to estimate the prevalence of pertussis infection among such patients. No vaccine will be administered during this study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Serological Evidence of Pertussis Infection

    Serological evidence of pertussis infection was defined as anti-pertussis toxin (PT) immunoglobulin G (IgG) level indicative of active or recent infection. The parameters presented were defined as follows: Seropositive = Subjects with anti-PT IgG ELISA levels ≥10 IU/ml , Seronegative = Subjects with anti-PT IgG ELISA levels < 10 IU/ml , Sero-confirmed infection = Subjects with anti-PT IgG ELISA levels ≥62.5 IU/ml , Active infection 1= Anti-PT IgG ELISA levels ≥ 100 IU/ml indicative of active or recent infection, Active infection 2 = Anti-PT IgG ELISA levels ≥ 125 IU/ml indicative of active or recent infection
