    abstract = {Antibodies against camel contagious ecthyma virus (CCEV) in camel sera were detected by passive hemagglutination test (PHT) with a mean antibody prevalence of 35%. The test revealed that the infection is widespread in all parts of the Sudan where camels are raised with variable prevalence rate. The antibody prevalence was 42% in Butana, 41 % in Darfor and 19 % in Blue Nile areas. The antibody prevalence was higher post rainy season (87.5%) compared to post rainy season (2.8%) confirming seasonality associated with the rainy season (June-October). The prevalence in age group 1-4 years was relatively higher (41%) in comparison with calves less than one year (32%) and adults (35%).}
