In nine disease surveillance points of Fujian Province, positive serum antibody against hepatitis A virus (anti-HAV), hepatitis B surface antigen (HBsAg), antibody against hepatitis Cvirus (anti-HCV) and antibody against hepatitis E virus (anti-HEV) in people of 1,237 families were determined and their distribution was analyzed to study familial aggregation of hepatitis virus infection by fitting to binomial distribution. Results showed that chi 2 of goodness-of-fit to binomial distribution was 49.89, 217.91 and 27.39 for anti-HAV, HBsAg and anti-HEV respectively, all with P < 0.001, indicating very obvious familial aggregation in HAV, HBV and HEV infection, with aggregation rates of 84.13%, 34.83% and 35.23% respectively. It suggests that familial aggregation is mainly caused by mother to infant transmission and horizontal transmission in families, and HEV infection can be transmitted through sex.

Yellow Fever

Yellow fever is a viral hemorrhagic disease caused by the yellow fever virus (YFV), a member of the Flaviviridae family. It is transmitted primarily by Aedes and Haemagogus mosquitoes in tropical and subtropical regions of Africa and South America. After transmission through a mosquito bite, the virus initially replicates in skin-resident immune cells such as dendritic cells and macrophages. These cells then migrate to the lymph nodes, where viral replication increases, eventually leading to...

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

Viral Hepatitis I: Introduction

Viral hepatitis is an inflammatory condition of the liver caused by infection with hepatotropic viruses, most commonly hepatitis A, B, C, D, and E. Despite variations in structure and transmission, all viruses mentioned infect hepatocytes and provoke immune responses that can hinder liver function. Additionally, some non-hepatotropic viruses can also lead to hepatic inflammation.Hepatitis A VirusHepatitis A virus (HAV) is transmitted through the fecal–oral route, typically by ingestion of food...
