one hundred sera from children 1 - 6 years of age, representative of a large serum collection, were tested for the prevalence of antibodies against different viruses. hemagglutination-inhibition (hi) antibodies were found in 68% for measles; 61 % for rubella; 75'% for influenza a2/hong kong/68, 16% for influenza b/md./59, 0% for group a arboviruses, 10% for group b arboviruses, 3% for phlebotom...

OBJECTIVE To review management of incidents involving exposure to blood reported to an occupational health unit. DESIGN Analysis of all reported incidents from January 1989 to June 1991. SETTING London teaching hospital. SUBJECTS 447 health care workers and students. MAIN OUTCOME MEASURES Immunisation against hepatitis B virus before exposure, proportion of known source patients tested ...

background the hepatitis delta virus (hdv) was first discovered by rizzetto in 1977 in a patient with chronic hepatitis b virus (hbv) infection. in 1980, it was shown that hdv was an infectious agent responsible for exacerbation of liver disease in patients with hepatitis. objectives the aim of this study was to determine the seroreactivity of, and to molecularly detect, hdv among hemodialysis ...

OBJECTIVES To determine the prevalence of antibodies to hepatitis B core antigen, hepatitis C virus, and HIV in the prison population of the Republic of Ireland and to examine risk factors for infection. DESIGN Cross sectional, anonymous, unlinked survey, with self completed risk factor questionnaire and provision of oral fluid specimen for antibody testing. SETTING Nine of the 15 prisons i...

Hepatitis B virus DNA was extracted from serial serum samples of a hepatitis B surface antigen-negative patient with antibodies to the core protein as the only marker of an infection with hepatitis B virus. This patient showed no symptoms of hepatic injury. Sequencing of the amplified viral DNA demonstrated multiple amino acid changes clustering in surface-exposed regions of the surface protein...

conclusions in conclusion, the prevalence of hbv infection was low in the south of iran, but genotype d represented the major hbv genotype in this population. among the variables, age, duration of hd, history of blood transfusion, and using shared hd devices influenced the prevalence of hbv among hd patients. results both kinds of assay determined that nine (5.88%) patients were hbv positive (h...

conclusions dental academics were unsure about the means of infection and prevention against hbv. many of them had not completed the immunization scheme and did not have the test of seroconversion. the serological analysis revealed unprotection, even after students completed the vaccination schedule. results of the 179 students surveyed, 58.1% knew about the degree of virulence of the hepatitis...

abstract background thalassemia patients that are conventionally treated by a regular transfusion regimen are exposed to blood born viral infections.the aim of this study was to investigate the seroprevalence of hepatitis b virus (hbv), hepatitis c virus (hcv) , and human immunodeficiency virus(hiv) among all multitransfused thalassemia patients in west north of iran. material and methods a ret...
