I: Certain infectious and parasitic diseases

B65-B83: Helminthiases

Helminthiases is a group of diseases caused by parasitic worms, also known as helminths. This group includes various types of conditions depending on the type of worm involved, such as tapeworms, roundworms, and flukes. These infections typically occur when a person comes into contact with contaminated soil, food, or water. Common initial symptoms include abdominal pain, diarrhea, and fatigue, though some people might not show signs of the disease at all. If left untreated, these worm infections can cause serious complications, such as malnutrition, organ damage, and growth delays in children. The disease affects the digestive system, and in severe cases, can also impact other systems like the respiratory and circulatory systems. Disease progression and specific symptoms can vary significantly based on the type of helminth causing the infection.
