Viral hepatitis And (Infectious disease)

Description:

Hepatitis A — the liver acute infectious disease caused by a hepatitis A virus (English HAV).
The virus is well transmitted till fecal oral ways, through the infected food and water, annually the virus infects about ten million people.  The incubation interval makes from two to six weeks, on average — 28 days.
In developing countries and in areas with the insufficient level of hygiene the coefficient of incidence of hepatitis A high and a disease is transferred in the early childhood. Samples of ocean water investigate on existence of a virus of hepatitis A when studying quality of water.

Symptoms of the Viral hepatitis And (Infectious disease):

Within a month (the incubation interval of 15-50 days, on average 30) after alleged infection can be expected the main symptoms: fevers, dyspepsias (nausea, vomiting, weight in a stomach and the right hypochondrium), weaknesses, urine darkenings (colors of strong brewing tea, spumescence) and then and jaundices - yellowing of scleras, skin, decolouration a calla. After emergence of jaundice quite often general state improves a little. Jaundice keeps about 3-6 weeks, sometimes longer. The disease on average lasts about 40 days. It in many respects depends on age, a condition of immunity, existence of the accompanying chronic diseases, accurate implementation of recommendations of the doctor. At some people (about 15%) the chronic form of an infection proceeding within 6-9 months is noted. Then usually there occurs recovery. The majority of cases of hepatitis A has typical symptoms, leads to recovery and does not demand special treatment.

Hard have an infection children are younger than one year, adult and elderly people. At adults the infection quite often proceeds with the expressed intoxication and jaundice, about 3 months on average are ill.

The risk of a lethal outcome at hepatitis A makes 0,1% at children, teenagers and adults have 0,3%.

Reasons of the Viral hepatitis And (Infectious disease):

The virus of hepatitis A has an acid resisting cover. It helps the viruses which got with the contaminated products and water to pass an acid protective barrier of a stomach. The virus of hepatitis A is steady in the water environment therefore hepatitis A epidemics often have the waterway of transfer. The virus of hepatitis A differs in a high immunogenicity, after the postponed disease durable lifelong immunity forms.

Treatment of the Viral hepatitis And (Infectious disease):

Recovery occurs without treatment. Modern treatment is more directed not to fight against hepatitis A viruses, and to reduction of concentration and removal from an organism of harmful substances which appear at damage and disturbance of functions of a liver. Therefore enter dezitoksikatsionny solutions, glucose, vitamins, gepatoprotektor (the drugs protecting liver cells). Antiviral treatment is not carried out. In hard cases the principles of therapy remain the same, but the volume of symptomatic therapy is more.
The forecast is favorable, functions of a liver are usually recovered completely. During the acute period it is necessary to adhere to a diet in volume of the 5th table on Pevznera, physical and mental rest is observed.
