Parasitic Diseases

Parasitic diseases are illnesses caused by parasites, which are organisms that live on or inside a host and depend on it for survival. These parasites can be microscopic, like certain worms and protozoa, or larger, like fleas and ticks. They can enter the body through contaminated food, water, or bites. Once inside, they can cause various health issues, from mild discomfort to severe illness. Common examples include malaria, giardiasis, and lice infestations. Preventing parasitic infections often involves proper hygiene, sanitation, and controlling insect populations. Understanding these diseases is essential for public health and personal safety.
