Abstract:
This study was conducted to determine the prevalence of Hookworm infection
among children of school age in Jos-North Local Government Area of Plateau State. A total of
2,800 stool samples from pupils aged 3 – 15 years and above, attending seven (7) primary schools
were collected and bio-assayed for Hookworm ova using direct smear and formalin – ether
concentration techniques. Six hundred and forty seven (647) pupils (23.11%) were found to be
infected by various parasites. Parasites encountered in order of occurrence include Ascaris (8.46%),
Entamoeba histolytica (5.64%), Hookworm spp (5.14%), Giardia (2.61%) and Trichuris (1.29%).
The result showed that 144 of the pupils had hookworm ova in their stool samples. This accounts
for 5.14% of the total population and 22.26% of the infected population. There was no significant
difference (P>0.05) between males and females with respect to the prevalence of the infection,
although more males (86) were found to be infected than females (58). There was significant
difference between the different age groups (P < 0.05), 3 – 6 yrs having the highest infection rate
(11.3%) while 15 yrs and above have the lowest (1.31%). The implications of the findings on the
occurrence and distribution of Hookworm infection and possible control measures were highlighted.
Further study is needed to identify which of the two Hookworm species is most prevalent.
