Cough For A Long Time Does Not Cure Need To Check For Pulmonary Fluke

The risk of lung fluke disease is less expected
Shrimp and crab are one of the favorite foods. The dish of shrimp and grilled crab has a very attractive flavor, stimulating the appetite so it is often made for many people. If ingested infected shrimp, crabs are infected but have not been thoroughly cooked, the person will pick up the body due to infection with trematode lungs with quite dangerous pathology.
Flukes (scientific name: Paragonimus) is a parasite when it enters the host, usually it attacks the lung but can also invade, causing prolonged cough, cough without finding a cause and causing Damage to the brain, causing severe headaches, can cause eye nerve atrophy, causing minor paralysis or mental disorders.
Host
Flukes are a disease that humans and other animals such as dogs, cats, pigs, weasels, tigers, leopards, wolves, foxes, mice, etc

. can become infected. Humans can be infected with pulmonary fluke, the average life span of a parasite lasts between 6 and 16 years. The causal agent is also rock crab, survey in some locations in Vietnam showed that more than 90% of rock crab samples carry tapeworm larvae, 100% of people have previously eaten roasted rock crabs infected with tapeworms lungs The number of people infected with lung fluke from eating stone crabs is much discovered.
Where parasitic lung flukes
The lung is a parasite where parasites are found but there are also cases of parasites in the skin, peritoneum, liver, pleura, intestines, testes, brain .



... when parasites in the brain, they can cause seizures for patients. Adult lung fluke spawns in the bronchi, the eggs are spread out by sputum due to patients spitting out the environment and continue to grow in intermediate vectors such as snails, crabs, shrimp . Fluked eggs after a period of underwater time, usually 60 days (cold season) and 16 days (hot season) will develop into hairy larvae After larvae leave the eggs, they look for snails to parasitize
After entering the snail, hairy larvae will develop into larval cells and become tail larvae. The tail larvae can swim in the water to find freshwater crabs and shrimp to parasitize as the second intermediate hosts of lung fluke. In crabs, snails, shrimp larvae of the lung live parasitically in the form of cysts in the chest muscle. After a period of 45-54 days to penetrate into snails, crabs, shrimp larvae can infect humans.



. If a person eats raw, uncooked snails, crabs, and shrimps containing cysticercosis, the cysticulmonary cyst will go to the small intestine, through the digestive tract to the abdominal sinus, they stay in the sinus cavity about After 30 days and then passing through the pleura one by one, they grow into adult parasites in the lungs.
Pathological symptoms
Flukes of the parasite living in a human or animal body will cause fingertip abscesses in the small bronchial branches of the lungs, sometimes in the lungs or other organs and cause pathological symptoms. specific. Manifestations of symptoms specific to the disease in most cases of lung fluke disease is causing abscess in the lungs, causing bleeding and coughing up blood; some cases of parasitic tapeworm pleural effusion Symptoms of infected people coughing up blood often lasts long, progression of acute attacks; coughing out blood is usually rust, brown or red; Most people do not have fever unless they have multiple infections. Symptoms of chest tightness, shortness of breath are non-specific manifestations and signs of pleural effusion when there are parasitic flukes in the pleura, less debilitating body. When subclinical tests are possible to find tapeworm eggs in sputum or in pleural fluid, some cases may be found in the stool. Most patients have increased eosinophilia. In the chest X-ray film, lung lesions are manifested by blurred nodules, small cavernous patches are always the main manifestation; The lymph nodes may swell and lesions in the lungs are more common in the lower regions.
Diagnosis of lung fluke
Diagnosis is mainly based on specific clinical symptoms such as hemoptysis, pleural effusion .



.. Need to combine with epidemiological factors related to the area with pulmonary fluke circulation. Diagnosis confirms the disease when a lung fluke egg is found in sputum, in pleural fluid or in stool. In addition, some additional tests should be done to support the diagnosis of pulmonary fluke disease such as chest radiography, blood counts to check eosinophilia; can do molecular biology testing, immunology ...
Prevent lung fluke disease
To effectively prevent pulmonary schistosomiasis, it is necessary to follow the principle of cutting links in their biological life cycle. However, in reality, the most effective measure is to coordinate communication and health education for the community to raise awareness and understanding, to change behaviors with the slogan and to act as "no. eat undercooked shrimps and crabs, especially grilled shrimps and crabs ".
