Infectious and Parasitic Diseases

Infectious and parasitic diseases are illnesses caused by microorganisms such as bacteria, viruses, fungi, protozoa, and parasitic worms. These diseases spread through contaminated food, water, air, insect vectors, or direct contact with infected individuals. They remain a major public health concern, especially in developing regions, due to their impact on morbidity and mortality. Prevention strategies include vaccination, sanitation, hygiene practices, vector control, and early diagnosis. Effective treatment and public health interventions are essential for reducing the burden of these diseases and improving global health outcomes.
