Parasitic Infections and Neglected Tropical Diseases (NTDs)

Parasitic infections affect billions of people worldwide, particularly in low-income, tropical, and subtropical regions. These diseases are caused by protozoa (e.g., malaria, giardiasis), helminths (e.g., schistosomiasis, ascariasis), and ectoparasites (e.g., lice, scabies). Neglected Tropical Diseases (NTDs), a group of 20 conditions identified by the WHO, include several parasitic infections and affect impoverished communities with limited access to clean water, sanitation, and healthcare. These diseases can cause chronic illness, disability, and economic hardship. Despite their prevalence, NTDs receive less research funding and global attention compared to other infectious diseases. Efforts to control and eliminate parasitic diseases include mass drug administration, vector control, improved diagnostics, and community education. Climate change and population movements are contributing to the spread of parasitic infections into new regions. Addressing these challenges requires global collaboration, sustained investment, and integration of disease control into primary health systems.
