Abstract
A cross sectional ultrasound screening survey for human cystic echinococcosis
(CE) was undertaken in the pastoral dist ricts of Moroto, Napak, Nakapiripirit and
Amudat in Karamoja sub-region; and agro-pastoral communities of Teso region, in
the districts of Kumi and Bukedea. Other areas of the survey included: Nakasongola
in Central region and Kasese district in the Western region of Uganda. A total of
3,636 participants were screened and 67 cases (1.84%) had CE. The organ most
affected was the liver 61.2% (41/67), followed by the kidney 17.9% (12/67),
spleen 10.44% (7/67), omentum 8.95% 6/67) and lungs 1.5% (1/67). All districts
screened had positive cases with the highest prevalence occurring in Napak (3.9%)
and the lowest in Nakapiripirit (0.45%). The prevalence of CE (0.5±0.3%) in South
Karamoja (Amudat and Nakapiripirit) was significantly lower (P<0.001, χ2= 18.98)
than in Central Karamoja (Napak and Moroto, 3.32±1.3%). The prevalence of CE
in Teso region was found to be 1.21±0.8%, Kasese 2.15±1.2 % and Nakasongola
2.7±1.3%. The prevalence in south Karamoja was lowest. Overall, there was no
significant difference (P<0.05; χ2= 0.12) in prevalence between males (1.7%) and
females (1.9%). However, in Karamoja females (2.2% CI: 0.8-3.6) were more likely to
be infected (χ2= 16; P<0.05) with CE than males (0.9% CI: 0.1-1.7). Sixty four percent
(n=43) of the cysts detected were viable.
