Aims: Pertussis, also known as whooping cough, is a highly contagious respiratory infection caused by the bacterium Bordetella pertussis. Though vaccines are the most successful and cost-effective way of preventing pertussis, the outbreak of pertussis is still high in the Amhara region. The study aimed to investigate the pertussis infection in Simada district, North West Ethiopia, 2021.
Methods: A community-based active surveillance was conducted in the Simada district from December 3/2020 to January 05/2021. A total of 43 cases was identified using the modified Centers for Disease Control and Prevention (CDC) pertussis diagnosis criteria and line lists. The collected data were entered into the Epi-data (Epidemiological Data) version 3.1 and analyzed using R version 4.03 software and descriptive statistics computed.
Results: A total of 43 cases were identified with an overall attack rate of 7.1 per 1000 population. All complicated cases occurred in children under four years of age. The most affected groups were females. There was an interrupted routine immunization service in the cluster at the health post-level to associate vaccination coverage with the occurrence of a pertussis outbreak. The outbreak was reported after three days of the occurrence of more transmission from person to person.
Conclusion: The outbreak of pertussis was high and the children were suffering. It is advisable to build capacity, consolidate routine vaccination services, and enhancing the vaccine cold chain management system, surveillance and early treatment of infected patients to control the expansion of pertussis.
