Abstract

Paragonimiasis (human infections with the lung fluke Paragonimus westermani) is an important public health problem in parts of Africa. This study was aimed at assessing the prevalence of Paragonimus infection in Ebonyi State. Deep sputum samples from 3600 individuals and stool samples from 900 individuals in nine Local Government Areas in Ebonyi State, Nigeria were examined for Paragonimus ova using concentration technique. The overall prevalence of pulmonary Paragonimus infection in the area was 16.30%. Six foci of the infection were identified in Ebonyi North and Ebonyi Central but none in Ebonyi South. The intensity of the infection was generally moderate. Of the 720 individuals examined, 16 (12.12%) had less than 40 ova of Paragonimus in 5 mL sputum and 114 (86.36%) had between 40 and 79 ova of Paragonimus in 5 mL sputum. While 2 individuals (1.52%) had over 79 ova of Paragonimus in 5 mL Sputum. Furthermore, there was higher prevalence of paragonimiasis in rainy season than in dry season. The results of this study indicated the growing public health threat posed by paragonimiasis in Ebonyi North and Ebonyi Central. A combination of chemotherapy, to bring relief to persons already infected by the disease and public health education related to paragonimiasis transmission to increase awareness of the infection in the areas is recommended.
