Trichinella spiralis is a common worm to affect humans who consume pork meat. In a country like India, where quality pork is rarely available even in urban areas trichinosis is a common infection. Trichinosis is a parasitic infection caused by the larvae of the worm. The adults then produce larvae that migrate through various tissues, including muscle. Trichinosis is listed as a " rare disease " by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). If the infection is heavy, patients may experience difficulty coordinating movements, and have heart and breathing problems. In severe cases, death can occur.
After consuming poor quality pork containing the cysts of the worm, larvae are liberated in the digestive system by the digestive juices. The larvae invade the small intestine mucous membrane and mature rapidly into adult worms. After seven days, female worms release new born larvae that migrate via the blood stream to the skeletal muscles. In the muscles the larva get encysted. Headache, fever, chills, cough, eye swelling, aching joints and muscle pain, itchy skin, diarrhea, or constipation follow the first symptoms. Infection occurs worldwide, but is most common in areas where raw or undercooked pork, such as ham or sausage, is eaten. If you have mild trichinosis, you may have no symptoms or only mild stomach or muscle aches. When your body is infested with hundreds of worms, though, more serious symptoms and complications can occur.
Trichinosis is a type of roundworm infection. Trichinella larvae live in the muscle tissue of animals, typically pigs, wild bears, horses, and many carnivores. Trichinosis occurs primarily among meat-eating animals (carnivores), especially bears, foxes and walruses. Most infestations are asymptomatic, although heavy exposure can cause various clinical manifestations, including diarrhea, fever, myalgias, and prostration. The few cases in the United States are mostly the result of eating undercooked game or home reared pigs. When a person eats meat containing live Trichinella cysts, the cyst wall is digested, releasing larvae that quickly mature to adulthood and mate in the intestine. The male worms play no further role in illness. The adults then produce larvae that migrate through various tissues, including muscle. Trichinella roundworms are most widespread in rural areas and in warm climates throughout the world. Persons with trichinosis usually have nausea, diarrhea, vomiting, fever and abdominal discomfort.
Trichinosis is a roundworm ( Trichinella spiralis ) infection, usually contracted by eating raw or undercooked meat. Trichinosis occurs primarily among meat-eating animals (carnivores), especially bears, foxes and walruses. Trichinosis , also called trichinellosis , or trichiniasis , is a parasitic disease caused by eating raw or undercooked pork and wild game products infected with the larvae of a species of roundworm Trichinella spiralis , commonly called the trichina worm . Most human infections result from pork, particularly in regions where pigs are fed uncooked meat scraps and garbage. Production of larvae continues for about 4 to 6 weeks, after which the female worm dies. The tiny larvae are carried through the body by the lymphatic vessels and bloodstream. The larvae penetrate muscles, causing inflammation.
Causes of Trichinosis
The common Causes of Trichinosis :
- Trichinella species develop in a single host and are spread from that host to the next without an arthropod intermediate. The intensity and frequency of exposure to infected meat determine the severity of the disease.
- When a person eats meat from an infected animal, trichinella cysts hatch in the intestines and grow into adult roundworms, which measure 2-4 mm long.
- Domestic meat animals (hogs) raised specifically for consumption under USDA guidelines and inspection can be considered safe.
- Metabolic disorder (e.g., glycogen and lipid storage diseases)
- Consumption of raw or undercooked pork products Consumption of raw or undercooked pork products
- Infections are related to cultural differences in food cooking and storing methods, specifically the inadequate cooking or freezing of meat.
- The muscles around the eyes, the tongue, and the diaphragm (the muscle separating the chest cavity from the abdomen) and the muscles between the ribs are the areas of the body most commonly affected by the condition
Symptoms of Trichinosis
Some common Symptoms of Trichinosis :
- History of having eaten rare or uncooked pork (bear and other wild carnivores or omnivores)
- Muscle pain and tenderness
- Swelling of the eyelids or face
- Pink eye (conjunctivitis)
- High fever
- Abdominal discomfort
- Muscle pain (especially muscle pain with breathing, chewing, or using large muscles)
- Eye swelling
Treatment of Trichinosis
- After muscle invasion, pain relievers may be given for muscle aches eventually, the larvae cysts in your muscles tend to calcify, resulting in destruction of the larvae and the end of muscle aches and fatigue.
- This drug is effective against worms limited to the intestinal lumen.
- Several safe and effective prescription drugs are available to treat trichinosis.
- The patient is watched closely for fever, abdominal pain, vomiting, and dermatitis (skin inflammation).
- Thiabendazole can kill adult worms in the intestine; however, there is no treatment that kills the larvae.
- The most effective treatment modalities are bed rest, analgesics, and antipyretics.
