(MENAFN- Gulf Times) A study co-authored by Qatar University College of Medicine (QU-CMED) researcher Dr Suhail Doi, who is also affiliated with the Australian National University, and published in the Lancet showed that mass deworming for hookworm and giant roundworm leads to a significantly greater reduction in prevalence in children than targeted deworming. However, no effect was seen for human whipworm.
The study was conducted in collaboration with The Australian National University in Canberra, Australia.
Soil-transmitted helminth (parasitic worms) infections are a major global health issue, causing substantial morbidity in the world's poorest populations.
Regular delivery of anthelmintic drugs is the mainstay for global soil-transmitted helminth control.
Deworming campaigns are often targeted at school-aged children, who are at high risk of soil-transmitted-helminth-associated morbidity.
However, findings from the study suggest that deworming campaigns should be expanded community-wide for effective control of soil-transmitted helminth transmission.
The research team carried out a systematic review and meta-analysis to compare the effect of mass (community-wide) and targeted (children only) anthelmintic delivery strategies on soil-transmitted helminth prevalence in school-aged children.
These worms are not common in Qatar, said Dr Doi, adding, 'but a study conducted this year by QU reported a prevalence of combined helminths of 7% in Qatar's migrant population, being highest among the western Asians.
'While this is an indirect impact of the burden of infection with Qatar's Asian neighbours, the eradication strategy recommended in this study will be of much greater consequence for these nations themselves.
He added: 'The results of this meta-analysis contribute to the evidence base surrounding the benefits of expanding drug therapy programmes for control of soil-transmitted helminths to all members of the community. Our findings support those of modelling and cost-effectiveness studies. We suggest that soil-transmitted helminth control guidelines should be re-evaluated with consideration of expansion to community-wide drug administration in endemic areas.
