The effect of sex on seasonal variation in single and double infection of cattle in Sierra Leone by Dicrocoelium hospes and Fasciola gigantica.

The incidence of dicrocoeliasis (61.8%) is higher than that of fascioliasis (25.5%) and their peaks do not occur at the same time of the year. The peak for the former occurs in the dry season while that of the latter occurs in the rainy season. The incidence of dicrocoeliasis and fascioliasis in female cattle was found to be higher than that of male cattle. Double infection was higher in female (14.7%) than in male hosts (9.6%).
