Rat lungworm, scientifically known as Angiostrongylus cantonensis, is a parasitic infection caused by a nematode (roundworm) that primarily affects the central nervous system. The parasite is typically found in rats, which serve as the definitive hosts. Humans can become accidental hosts by consuming raw or undercooked snails, slugs, freshwater shrimp, crabs, frogs, or contaminated produce carrying infective larvae.

Rare lung diseases are a group of uncommon respiratory conditions that affect the lungs and airways. These diseases often present unique challenges in diagnosis and treatment due to their low prevalence and the complexity of their symptoms. While each rare lung disease has its specific characteristics, they generally lead to significant respiratory issues, impacting a person's quality of life.
Rare and orphan diseases are medical conditions that affect a small percentage of the population. Definitions of rare diseases vary by country.
