What is hepatitis A

First: hepatitis A, referred to as hepatitis A, is an acute infectious disease caused by hepatitis A virus (HAV). The clinical manifestations were acute onset, chills, fever, anorexia, nausea, fatigue, hepatomegaly and abnormal liver function. Jaundice occurred in some cases, asymptomatic infection cases were more common, generally did not turn into chronic and pathogen carrying state.

Second: the disease of hepatitis A is generally caused by hav. After entering the body by mouth, hav enters the blood stream through the intestines, causing viremia. About a week later, hav reaches the liver, and then it is discharged into the intestines and feces through bile. Fecal detoxification can last 1-2 weeks. The main organs invaded by hav were liver. Pharynx and tonsil may be the sites of HAV extrahepatic reproduction.

Third: hepatitis A is a common intestinal infectious disease caused by hepatitis A virus (HAV) infection, which is more common in children and adolescents. The general incubation period is 2-6 weeks. The disease can be divided into four types: acute jaundice type, acute non jaundice type, cholestasis type and severe type. The course of disease is 2-4 months. Winter and spring is the peak of hepatitis A.
