Viral hepatitis E

Description:

Viral hepatitis E - the viral infection from conditional group of fecal and oral hepatitises which is characterized by damage of a liver, an acute cyclic current and heavy manifestations at pregnant women.
езервуар and an infection source - the person, the patient or the carrier. The period of contageousness of a source is definitely not determined probably it is similar to that at a viral hepatitis A. Virus find in excrements in early terms of a disease in 15% of cases at easy and medium-weight forms; at a heavy current it is found almost in 50% of patients. Pathogenicity of a viral hepatitis E for a chimpanzee, pigs and other animals is proved.

The transfer mechanism - fecal and oral, a way of transfer - preferential water. There are data on distribution of the activator and a contact and household way. Assume a possibility of infection with a viral hepatitis E at consumption of crude mollusks. In favor of water as the main factor of transmission of infection the low ochagovost, developing of the mass diseases connected with rainy seasons and with high standing of level of ground waters testify.

Symptoms of the Viral hepatitis E:

Reminds the course of a viral hepatitis A. Naiboley the viral hepatitis E in II and III trimesters of pregnancy is dangerous. At the same time the current of the icteric period is transient, it quickly passes into acute hepatic encephalopathy. Phases of acute hepatic encephalopathy quickly replace each other, and patients fell into a deep coma. The hemorrhagic syndrome is strongly expressed. Death of a fruit comes till the birth. In this category of patients the lethality fluctuates within 10-20%, and in certain cases can reach 40-50%.

Reasons of the Viral hepatitis E:

The activator - the RNA-genomic virus which is conditionally included in the sort Calicivirus though in the genetic relation it has essential distinctions. Virions of rounded shape, are deprived of a supercapsid. In general the viral hepatitis E is less steady, than a viral hepatitis And. It well remains at a temperature - 20 °C and below. Quickly collapses at freezing thawing, under the influence of chlorine-containing or iodinated disinfectants.

Treatment of the Viral hepatitis E:

In uncomplicated cases similar to that at a viral hepatitis And.
