Parasitic Diseases

Parasitic Diseases are illnesses caused by parasites such as protozoa, helminths (worms), and ectoparasites that live on or inside the human body. Common parasitic diseases include malaria, amoebiasis, giardiasis, schistosomiasis, and intestinal worm infections. These diseases are most prevalent in tropical and subtropical regions, particularly in areas with poor sanitation, unsafe water, and limited healthcare access. Parasites are transmitted through contaminated food or water, insect vectors, or direct contact with infected individuals or environments. Symptoms vary depending on the parasite and may include diarrhea, abdominal pain, anemia, malnutrition, fever, and organ damage. Children and immunocompromised individuals are especially vulnerable. Public health strategies for controlling parasitic diseases focus on improving sanitation, access to clean water, vector control, health education, and timely diagnosis and treatment. Reducing parasitic disease burden is essential for improving global health and socioeconomic development.
