Popular characteristic _ general knowledge of the first type hepatitis
( 1 ) The infection rate of first type hepatitis is closely related to social economic situation and personal hygienic habit. It is lower than developing countries that the hepatitis A antibody of developed country is positive to lead, the upper strata crowd is lower than the crowd of lower floor. Crowd over the 20 our country, 90 antibody positive in about hepatitis A, only Japanese young people 2 0 % - 3 0 % Positive. This is because Japan is economic and fast growing after the war, living conditions and health facilities are obviously improved, and does not need the people excrement to apply fertilizer, so the morbidity of hepatitis A drops greatly.
( 2 ) In developing country, because hepatitis A virus infect, take place in infant and Childhood more generally, often beautiful and relatively light, it is difficult to be found, mostly inferior and clinical type, and developed country, hepatitis A virus infect, take place in adult mainly, under the age of 15 children few person who dye, mostly clinical type.
( 3 ) In recent years, some areas and cities in our country, because the constant improvement of material and culture life, environmental sanitation and living conditions, crowd's immune protective screen of hepatitis A has downward trend gradually, more easily infected group increase, and pass to the big age group, jaundice type and serious disease and hepatitis will rise, mortality will thereupon increase, but the countryside where some life is poor, the morbidity target of hepatitis A, is still mainly the children under the age of 10.
( 4 ) Because different factors such as social economic situation and habits and customs, in the disease is studied clearly, 3 kinds of positive rate of hepatitis A antibody of peculiar age appear.
( 3 ) Will strengthen and protect the persons who keep in touch, take a good rest, enough sleep, diet is imbued with nutrition, easy to digest, keep the air fresh in the room, strengthen organism resistance, prevents diseases such as cold, diarrhoea,etc. from taking place.
See until social economic situation low living crowded, the intersection of hygienic habit and worse developing country mainly while being type, the above-mentioned 90 crowd has already been infected with hepatitis A and virus in children and teenagers period, and keep higher antibody level all one's life, seldom have illness coming on twice.
2 type see on social the intersection of economic situation and superior developed country, the intersection of hepatitis A and the intersection of antibody and positive characteristic of rate its mainly, increase and rise with age. Originally first type hepatitis was children's common disease, but these countries saw more adults, this is because these national sanitary conditions are good, and children's social scope of activities is small, seldom infected, and the adult, often go to the prevailing country of hepatitis A to go to travel, therefore is apt to be infected with hepatitis A and virus.
See on nearly with the intersection of external world and obstructed exchanged closeness country mainly while being type, the residents that alive after hepatitis A of once breaks out prevailingly, the positive rate of hepatitis A antibody is nearly 1 0 0 % , And the child born after prevailing, the positive rate of hepatitis A antibody was nearly 0, once for a certain reason, exposed to hepatitis A and virus, will present first type hepatitis to prevail big again.
Thought the excrement - mouth route to be a spread route of only hepatitis A and virus in the past, but really there are reports infected with the first type hepatitis because of accepting blood transfusion in recent years. This is because first type hepatitis has been before appearing clinically and beautifully for 7-10 days, there is transient virus blood disease, donate blood at this moment, obviously have a potential danger of transmitting the first type hepatitis. When blood donors donate blood, the incubation period that is just in hepatitis A, healthy seemingly, but their blood contains hepatitis A and virus actually. , the blood offered inputs other patients.
