A REVIEW OF HUMAN HELMINTHS: GLOBAL PREVALENCE, REGIONAL CONTEXT, AND CONTROL MEASURES WITH REFERENCE TO UZBEKISTAN CONTEXT
Abstract
Soiltransmitted helminths (STHs) remain among the most widespread parasitic infections worldwide, affecting over 1.5 billion people. This review focuses on a representative helminth type — intestinal nematodes (roundworms) — examines global prevalence, considers regional data from Uzbekistan, and discusses control measures including mass deworming, sanitation improvement, and public health strategies. While comprehensive recent data for Navoiy Region (Uzbekistan) are limited in public sources, national studies indicate helminthiasis remains one of the most common parasitic diseases in the country. Preventive and therapeutic measures, including periodic deworming and hygiene campaigns, remain crucial to reducing disease burden.
