Abstract

Cryptosporidium is a protozoan pathogen that causes cryptosporidiosis, a gastrointestinal illness with significant public health implications worldwide. This article provides an overview of the global distribution, public health implications, and clinical impact of Cryptosporidium. The parasite is found in both developed and developing countries, with transmission occurring through contaminated water, food, and direct contact. Cryptosporidiosis outbreaks pose substantial challenges to public health, leading to economic burdens and affecting vulnerable populations such as young children and immunocompromised individuals. The clinical impact of Cryptosporidium infections can range from self-limiting diarrhea in immunocompetent individuals to chronic and severe illness in immunocompromised individuals. Prevention and control strategies encompass improving water and food safety, enhancing sanitation infrastructure, promoting hygiene practices, and investing in research for effective vaccines and treatment options. By addressing the global distribution and impact of Cryptosporidium, public health efforts can be strengthened to reduce the burden of cryptosporidiosis and safeguard population health
