Parasitic Disease

Parasitic diseases: parasites invading humans; lesions/clinical vary by species/site. Worldwide, tropics/subtropics, poor sanitation. Drug treatment = most effective anthelmintic per species.

Common Symptoms

Periumbilical pain; nail granules; strongyloidiasis; pallor; abdominal pain; weight loss; dyspepsia

Causes and Pathogenesis

Parasite load/virulence (50%): mechanical damage/toxic enzymes/eosinophilic abscess/granuloma. Host immunity (50%). Source: carriers/reservoirs/paratenic hosts. Routes: oral, insect bite, skin penetration, transplacental, respiratory, transfusion. Transmission conditions: vector/intermediate host; suitable environment; poor hygiene. Susceptible: non-immune/children. Damage: (1) nutrient theft; (2) mechanical (migration/obstruction); (3) toxic/immune (Clonorchis cholangioproliferation, schistosome antigen-antibody glomerulonephritis, hookworm anticoagulant).

Treatment

Drug, supportive, surgical therapy

Preventive Measures

Mass treatment; vector control; health education; bed nets.
