  1. Fulltext. An extensive ultrasound and serologic study to investigate the prevalence of human cystic echinococcosis in Northern Libya.

    Article - En anglais


    A prevalence study of abdominal cystic echinococcosis (CE) was undertaken in the northwest, northcentral, and northeast regions of Libya.

    A total of 36 villages along the coast were included, in which 20,220 people were screened by portable ultrasound.

    Three hundred thirty-nine (1.7%) were diagnosed with CE.

    There was no significant difference between CE prevalence rates in the three regions of Libya (mean=1.6%) ; however, intervillage rates were variable, ranging from 0% to 4.5%. The prevalence of CE increased significantly with age (P<0.0001) and females were significantly more affected (2%) than males (1.3%) (P<0.0001).

    Cases of CE were distributed among 3.2% of housewives, 2.6% of farmers, 2.3% of male civil servants, 1.3% of female students, and 1.1% of male students.

    Housewives (P<0.0001) and students (P<0.0001) were significantly more at risk for CE.

    A statistically significant proportion (62% [210 of 339]) of CE cases kept dogs (P<0.0001).

    Of the ultrasound-positive CE cases 69% (233 of 339) were antibody seropositive by ELISA using Echinococcus granulosus hydatid cyst fluid antigen B. Blood samples (n=10,096) collected onto filter papers were taken randomly from ultrasound-negative people who entered the study, of which 11.2% were found to be seropositive.

    Seropositivity increased with age (P<0.0001), with females exhibiting higher seroprevalence than males for all age groups (P<0.0001). (...)
