Human Helminth Disease Signs And Ways To Treat Helminth Disease
Human helminth disease is caused by a type of roundworm known scientifically as Trichinella spiralis. T.spiralis can cause acute illness on a host both in adulthood and in larvae.
A parasite (parasite) of carnivorous mammals, including pigs and mice, but in nature. T
Although pigs and pork products are often a source of infection in humans, they are sometimes infected by eating raw meat from some wild animals such as bears
. TWISTED SPREAD
Adult worms: Very small, milky, size;
Worms: 1.5mm x 0.04mm. The curved-tailed male worm has two conical appendages on the tail, which are used to hold female worms during intercourse. Between these two bodies there is a point, which can be exposed and acts as a sexual organ
Female worms: 35mm x 0.06mm. Female worms have a vagina in the anterior half of the body, the head adheres to the intestinal membrane, the body attaches to the small intestinal folds, so when the female worms lay, the larvae directly into the small intestinal mucosa, ..
Dimensions: 100 xm x 6 µm, so it is possible to pass through the blood vessels in the muscles. In meat fibers, the larvae can reach sizes of 900 - 1,300 µm x 35 - 49 µm. Adult larvae clad in sacs (glands) have gastrointestinal tracts, similar to adult worms, which are sexually distinguishable, although the sexual organs are not yet complete Usually a wrap has only one larva, but may also be more. After a while, the cysts will become calcified.

2. DEVELOPMENT OF TWISTED BREAST DISEASE
When raw or undercooked meat-eaters have Trichinella spiralis larvae, larvae to the stomach, under the effect of digestive juices, emptying the shells, stage 1 larvae (L11 (L1) causing the infection are released, and develop into adult and adult worms after four molting in about 2 days.
At the end of the small intestine, after fertilization, the male helminth dies, while the female worms give birth to stage 1 larvae, which then develop into stage 2 larvae, enter the circulatory system, and the larvae pass away. enters small blood vessels in the small intestine of the small intestine, in the small intestine, along the portal vein to the liver, on the right heart and pulmonary artery.
. In the lungs the larvae enter the capillaries and then to the left heart, thereby spreading to the organs and depositing anywhere in the body. Nematode worm larvae only cocoon in striated muscle, especially diaphragm, chewing muscle, intercostal muscle, larynx muscle, tongue muscle, cheek muscle, chest muscle, delta muscle, buttock muscle, biceps muscle, etc
The life span of adult worms is only a few weeks to a few months, but the life expectancy in the larvae can last for many years and often hardens within 1 year. Wrapped in size of 400 µm, located vertically of the muscle fibers, each containing a larvae of 800 dàim in length, rolled up into a spiral. The larvae have very high resistance: In the animal meat is operated, though the rotten larvae can live 2-3 months.
At the temperature of -100C: The larvae in the sac live for 10 days. However, larval resistance is poor when exposed to high temperatures.
500C temperature capable of killing larvae 5 - 10 minutes. Therefore, eating cooked meat is the safest way to avoid getting sick.
Rats and wild animals are the hosts of this parasite.
Usually mice get infected by eating this meat. Usually infected mice are caused by eating meat from each other, infected pigs are caused by eating infected mice meat, infected people by eating uncooked pork (including wild meat).
In the case of people infected with helminths, the parasitic larvae in the human body are not transferred to any other host (being eaten), so it is not possible to continue the development cycle and create the phenomenon. parasitic dead end.
3. EPIDEMIOLOGICAL CHARACTERISTICS OF TWISTED DISEASES
Wormworm is found in many parts of the world. Worms have three subspecies, indistinguishable in form but different in geographic distribution: T.spiralis spiralis is most common in temperate regions T.spiralis nativa in the Arctic region, T.
.spiralis T.spiralis nativa in the Arctic region, T.spiralis nelson in Africa and Southern Europe.
People become infected by eating raw or undercooked meat of infected animals, especially pigs. Wild animals also play an important role in spreading the disease, especially bears, wild bears and wild boars.
The disease can cause epidemics when there are many infected animals in the area and the practice of eating raw meat In Vietnam, recently a diaper epidemic report occurred in Quai sheet commune, Tuan Giao district, Dien Bien province, when people ate sausages (made from unripe pork) at a wedding party that made 23 people infected. sick.
Many products that mix pork with other meats are also sources of contamination

4. SYMPTOMS OF TWISTED BREAST DISEASES
Diverse disease symptoms, easily confused with many other diseases.
. The variety and severity of the disease depends on the number of parasitic worms, the age, invasive tissue and the patient's resistance.
