Core Viewpoint - The article highlights the health risks associated with consuming raw or undercooked crabs, particularly the potential for lung fluke infection, which can lead to serious health issues [1][2]. Summary by Sections What is Lung Fluke Disease? - Lung fluke disease, also known as paragonimiasis, is caused by the lung fluke parasite, which requires two intermediate hosts for its development: freshwater snails and freshwater crabs or other crustaceans [2]. - The lifecycle involves the eggs hatching in water, infecting snails, and then transferring to crabs, where they develop into infectious larvae that can infect humans when consumed raw or undercooked [2]. Symptoms of Lung Fluke Disease - Symptoms vary based on the number of parasites, the infected organs, and the individual's immune response [3]. - Acute symptoms may include fever, fatigue, loss of appetite, abdominal pain, and diarrhea, which can be easily overlooked [3]. - Severe cases can lead to allergic reactions, high fever, chest pain, cough, and potential organ damage, with chronic symptoms being more complex and organ-specific [3]. Diagnosis - Diagnosis relies on epidemiological history, clinical symptoms, laboratory tests, and imaging studies [4]. - The gold standard for diagnosis is finding lung fluke eggs in sputum or feces, with blood tests and imaging aiding in the diagnosis [4]. Prevention - Prevention focuses on avoiding the consumption of raw or undercooked crabs and other freshwater crustaceans [5]. - It is essential to ensure thorough cooking of crabs and to maintain food hygiene to prevent cross-contamination [5].
