If you are going to relax in exotic countries, be prepared to face exotic diseases. When residing abroad, you can catch a terrible parasite. His name is Richard.
In ancient times, the sacrifice was called a fiery serpent, and infection with risus - drakunculus - literally translates as "defeat by small dragons".
What is rishta
Rhestia, or dracunculus, is a skin disease that is provoked by females of the round worm Dracunculus medinensis. In the human body, the worm, more precisely, its larvae, gets into the water. From the intestine, worms climb into the lymph nodes where they grow and mate. The male dies after pairing, and the female is placed in the subcutaneous tissue. The incubation period lasts from three to eighteen months and ends with the moment of female maturation. The host of the parasite has abscesses.
The parasite lives in Africa, Arabia, Afghanistan, India and Persia. He was also brought to Brazil. In the territory of the CIS, the worm settled in the city of Stara Bukhara.
Treatment of dracunculiasis
Retracted only by operational means. The process can take a long time, because if you damage the worm, a toxic liquid will enter the wound. At the same time, the worm capture the head with a tweezers, and then gently pull it out and wound on the tool. Sometimes the female is sterilized and molded before surgery. Extracting a worm is a rather long process, since it can reach a length of one and a half meters.
It is easy to diagnose the presence of this parasite: it puts under the skin paths that create a peculiar relief on the surface, and from the abscess you can see the head of the worm. The owner of the scourge while experiencing itching and severe pain in the places of injury, the skin is sealed, there are abscesses with bubbles. In addition, the patient may rise in temperature, fever appears. The worm's favorite location is the lower limbs.
The consequences of this parasite can be very sad. These are various allergic reactions, infection of the blood, gangrene.
There are cases of self-healing when the sacrifice dissolved in the host's body. Such a variant of the course of the disease is possible, if the female contacts the water lays the larvae, and then itself dies afterwards.
Prevention of contamination by the straw is carried out globally. To protect the population from this parasite, the following measures are taken:
- In countries where this creation is live, water treatment is regularly performed;
- It is forbidden to drink raw water, and before it boils, it is recommended to filter it through a dense cloth;
- The parasite shopkeepers have dogs and rabbits-cyclops, which swallow worms, so they are sterilized and destroyed;
- A record and thorough examination of all patients infected with saccharin is conducted;
- The contact of patients with drinking water is excluded;
- The population is provided with cleaned tap water.
Fortunately, due to the efforts of the World Health Organization, there are not so many leftovers infected by this parasite. In recent years, cases of mass contamination are known only in Africa. For thirty years, the number of cases of infection has decreased: if in 1980 they were about three million, then by 2011 only 1058 cases of occurrence of this disaster are known.
