Deworming Limited access to essential medicine poses a challenge to the eradication of<unk>  worldwide. Also, it is a public health concern that rates of post-treatment re-infection need to be determined and addressed to diminish the incidence of untreated re-infection. Lastly, with mass drug administration strategies and improved diagnosis and prompt treatment, detection of an emergence of antihelminthic drug resistance should be examined. Mass Drug Administration (preventative chemotherapy) has had a positive effect on the disease burden of<unk>  in East and West Africa, especially among children, who are at highest risk for infection. Sanitation Infection can be avoided by proper disposal of human feces, avoiding fecal contamination of food, not eating soil, and avoiding crops fertilized with untreated human feces. Simple and effective proper hygiene such as washing hands and food is recommended for control. Improved facilities for feces disposal have decreased the incidence of whipworm. Handwashing before food handling, and avoiding ingestion of soil by thorough washing of food that may have been contaminated with egg-containing soil are other preventive measures. Improvement of sanitation systems, as well as improved facilities for feces disposal, have helped to limit defecation onto soil and contain potentially infectious feces from bodily contact. A study in a Brazilian urban centre demonstrated a significant reduction in prevalence and incidence of soil-transmitted helminthiasis, including<unk> , following implementation of a citywide sanitation program. A 33% reduction in the prevalence of<unk>  and a 26% reduction in the incidence of<unk>  was found in a study performed on 890 children ages 7–14 years old within 24 different sentinel areas chosen to represent the varied environmental conditions throughout the city of Salvador, Bahia, Brazil. Control of soil fertilizers has helped eliminate the potential for contact of human fecal matter and fertilizer in the soil.
