Helminthiasis refers to infections caused by parasitic worms, including nematodes (roundworms), trematodes (flukes), and cestodes (tapeworms). These parasitic infections are prevalent in various parts of the world, particularly in areas with poor sanitation and limited access to clean water. Common helminth infections include soil-transmitted helminths like Ascaris lumbricoides, Trichuris trichiura, and hookworms, as well as schistosomiasis and intestinal tapeworm infections. Clinical symptoms of helminthiasis vary depending on the type of worm and the severity of the infection. Common manifestations include abdominal pain, diarrhea, weight loss, anemia, and nutritional deficiencies. Chronic and heavy infestations can lead to long-term health consequences, particularly in children. Preventive measures for helminthiasis involve improved sanitation, access to clean water, and health education on proper hygiene practices. Mass drug administration programs with anthelminthic medications target high-risk populations in endemic areas. Research efforts focus on developing new drugs, understanding the immunology of helminth infections, and exploring innovative strategies for controlling the spread of these parasitic worms.
