And whether you know...
Ascaridosis – a helminthic invasion, parasitizing in a human body of roundworms – ascarids. The most widespread disease in temperate and warm climate, in areas where fields and kitchen gardens fertilize not disinfected excrements of the person. The infection season in a temperate climate makes the period from April to October, in warm climate all the year round.
Ascarids — the large diclinous worms parasitizing in a small bowel of the person who is the only owner of helminth. The female of an ascarid lays up to 200 thousand eggs per day. These yet not mature eggs with excrements of the person get to environment. Shell and core bathrooms and violations of the rules of hygiene promote further hit of eggs to the soil where at a depth up to 20 cm they ripen. At an optimum temperature 24 C maturing of eggs happens in 14 days. If hit to the soil happened the late fall, eggs remain viable till spring and when there comes optimum temperature condition, continue maturing.
Infection occurs at the use in food of badly washed up vegetables contaminated by the ripened eggs through dirty hands, is much more rare with drinking water. The ascaridosis at children occurs more often than at adults, it is connected with the fact that children fulfill requirements of hygiene much less often. At hit in intestines eggs leave larvae which proburavlivat mucous guts and get to a blood stream. Together with a venous blood of a larva move to capillaries of air cells and already from there to bronchial tubes. At cough they are had to an oral cavity and swallowed back in intestines. Where adult individuals of an ascarid develop. All development cycle of a parasite from infection before emergence in excrements of the patient of unripe eggs takes 2,5-3 months, the general symptoms of an ascaridosis are characteristic of this period.
Course of an ascaridosis
The course of an ascaridosis is divided into two stages: migratory and intestinal. Various symptoms and complications of an ascaridosis are characteristic of them.
The early stage of an ascaridosis is a stage from infection of the person before secondary hit of larvae in intestines call migratory. Disease during this period can be and asymptomatic, but the febricula, temperature increase, cough is most often observed. The small tortoiseshell and other allergic enanthesis is in certain cases shown.
Late stage – intestinal. At an intestinal stage of a disease rather explicit symptoms of an ascaridosis are shown. At patients nausea, abdominal pains which have character of pains, hypersalivation, loss of appetite is observed. In the course of parasitizing helminths remove in blood toxins in communication with what the headache develops, dizziness, increased fatigue, in certain cases are present nightmares. The ascaridosis causes a gnash in children teeth at night, frequent bronchitis, asthmatic asthma, an anemia. Children become nervous, scattered, progress in study decreases.
At a late stage of an ascarid can get into a gall bladder and bilious passes, pancreat ducts. The complications of an ascaridosis caused by such penetration purulent cholecystitis, liver abscess, acute pancreatitis, appendicitis. In certain cases there can be an intestinal impassability caused by obstruction of a gleam of intestines a ball of ascarids. The ascaridosis considerably burdens the course of infectious diseases of dysentery, measles, scarlet fever.
Prevention and treatment of an ascaridosis
Prevention of an ascaridosis first of all means implementation of all requirements of hygiene. Fresh vegetables and fruit without fail should be washed carefully, rinsing boiled water. Children follows, as soon as possible to accustom to wash hands, it is correct to use a pot and a toilet bowl, not to gnaw nails and not to pull various objects in a mouth. Unfortunately, at arrangement of street toilets on seasonal dachas we often forget about hygiene in this connection prevention of an ascaridosis cannot be considered full and sufficient.
Treatment of an ascaridosis has to be appointed by the doctor after carrying out laboratory analyses. Self-treatment by national methods, for example reception of a wormseed seed, laxative, an enema, does not bring result. Most often such methods lead to complications. Usual protivogelmintny means give 80% of efficiency. Good results are yielded by treatment of an ascaridosis bioresonant therapy, positively proved the antiparasitic Liomed-Biot device. This device kills not only adult individuals, and and a larva and egg.
