INTESTINAL PARASITIC INFECTIONS FROM MIGRANT WORKERS IN MALAYSIA Malaysia imports a high number of migrant workers from several neighbouring countries to cope with the expanding workforce especially in the low skill category. Migrant workers entering the country are screened for communicable diseases such as HIV, STD and TB. However, screening for parasitic infections are often neglected and this may pose a high risk of transmission due to poor hygiene and sanitation. Therefore, this preliminary study was undertaken to identify those parasitic infections that might occur in migrant workers entering Malaysia.  219 faecal samples were examined from 297 volunteers, originated from Indonesia (n=146, 49.2%), Nepal (n=84, 28.3%), Myanmar (n=26, 8.8%), India (n=21, 7.1%), Bangladesh (n=19, 6.4%) and Vietnam (n=1, 0.3%).  A high proportion of the workers (n=147, 67.1%) were positive for at least one parasite species.  Up to six parasite species were recorded from the 219 volunteers with the ascarid nematode Ascaris lumbricoides (70.7%) being the most prevalent, followed by Entamoeba sp. (27.2%), hookworm (24.5%), Giardia sp. (18.4%),Trichuris trichiura (12.9%) and Hymenolepis nana (1.4%). Summary  The increase in parasitic infections amongst foreign workers compared to a decade ago (36%, 173 stool samples)(Anuar Zaini et al., 2002) is likely to be due to higher populations of workers inhabiting crowded quarters with inadequate sanitation and poor personal hygiene.  High prevalence of Ascaris coincides with values of up to 93.3% in soil sampled from playgrounds in Peninsular Malaysia ( Mohd Zain et al, 2014).  These preliminary results suggest that the authorities should without delay evaluate methods of prevention, control and treatment with the view to implementing a more effective public health policy for migrant workers entering and residing in Malaysia.

Journal of Helminthology.(DOI /S X ) Workers were recruited from the manufacturing, construction, plantation, domestic and services sectors. Faecal samples, fixed in formalin ether followed by iodine staining, were examined microscopically for helminth eggs (x10) and protozoan cysts (x40).  Workers from India and Bangladesh showed the highest infections with prevalence above 80% and according to host gender, male workers (73.1%) were more heavily infected than females (55.4%).  Relative to sector, services recorded the highest prevalence (80.3%), followed by manufacturing (76.1%), domestic (54.9%), and construction (50%).
