The virology and serology of hepatitis: an overview.
At least five viruses are recognised as causes of acute hepatitis which, in some instances, can develop into chronic disease. The viruses of hepatitis A (HAV) and hepatitis E (HEV) are spread predominantly by the faecal-oral route, whereas hepatitis B, C and D viruses (HBV, HCV and HDV) are spread by blood and other body fluids. The incubation period ranges from about four weeks for HAV to three months for HBV. The diagnosis mainly depends on the detection of various serological markers. The control of infection in the United Kingdom has been facilitated by the introduction of vaccines for HAV and HBV and screening blood for HBV and HCV. Good hygiene and sanitation, the availability of sterile equipment, and measures to modify the behaviour of high-risk groups such as injecting drug users, are also important in the prevention and control of viral hepatitis.
