What a issue of long _'s general knowledge is infected it is the strongest when hepatitis A is infective
Hepatitis A virus exist Jia the intersection of hepatitis and patient Yu mainly and in the invisible excrement and urine of the infeted, arrange poisonous long to 2- 3 week, hide end and have illness coming on initial stage a large number of poisonous platoon. So, it is the strongest to be infective in several days before first type hepatitis later stage of incubation period and jaundice appear. When disappearing gradually after jaundice and peak, condition take a favorable turn, infective to subside also. Two weeks after general jaundice appears, although some patients can still produce virus particle very much in the excrement and urine, but the real infection obviously drops; In 3 weeks after jaundice appears, it is already very difficult to find hepatitis A and virus in the patient excrement and urine, it is infective not to basically have at this moment. Someone thinks in room one, the acute A type, hepatitis B patient live in recent years, go on, follow up a case by regular visits to, observe to the intersection of hepatitis B and patient that it leave hospital, find the intersection of cross infection and first type phenomenon of hepatitis. So, first type hepatitis patient subdueing stepping back to jaundice, has not needed to and then limit or isolate strictly yet.
