    Sammanfattning : Primary HIV-1 infection (PHI) is usually defined as a mononucleosis-like illness associated with seroconversion to HIV. In earlier studies using 1st generation antibody tests, the duration of the 'window period' from infection to detection of specific HIV-antibodies, could be 2 to 3 months, or longer. LÄS MER

  3. 2. Hepatitis B virus infection and genomic changes from a long-term perspective

    Sammanfattning : Hepatitis B virus is a non-cytopathic virus with a small, circular, partially double-stranded DNA of 3.2 kb. It causes acute and chronic inflammatory liver disease and hepatocellular carcinoma (HCC). Retesting of stored sera from an outbreak of acute hepatitis in 1969-72 allowed identification of 126 cases of acute hepatitis B. LÄS MER

    Sammanfattning : Despite 25 years of effective vaccines and availability of treatment options for 15 years, hepatitis B virus (HBV) infections continue to be a major global health problem. In Sweden, selective screening and vaccination programmes are used in defined high-risk groups such as newborns of chronic HBV carrier mothers and health care workers with risk of blood exposure.

    Sammanfattning : Hepatitis C virus (HCV) is an important cause for chronic liver disease worldwide. Infection by HCV may resolve spontaneously, but in the majority of cases a chronic infection is established, that may result in liver cirrhosis and hepatocellular cancer. LÄS MER
