Text B.
In hepatitis the source of virus is a sick person who may spread the infection by personal contract from the last days of the incubation period during the entire course of the disease. But the infection is particularly virulent in the prodromal period and in the first week of the disease. The patient’s blood being highly infective, even a small dose of 1 ml may be dangerous for a person.
Infection enters the body through the mouth when eating infected food or drinking water, and parenterally during transfusions of blood, plasmaand serum, prophylactic vaccinations and infections due to inadequately sterilized instruments.
Epidemic hepatitis most commonly occurs late in autumn, early in winter, or in spring. The incubation period lasts from 2 to 14 days.
Botkin’s disease causes inflammatory changes and degeneration of hepatic cells and damage to the bile ducts due to which bile enters the lymph flow and subsequently the blood. The tissue of the spleen, gallbladder and the nervous and endocrine systems become involved simultaneously with the liver.
