12/01/2004 - "Lifelong immunity is conferred by infection or vaccination, so anti-HAV seroprevalence studies can be used to indicate which populations are susceptible to infection. "

03/01/2017 - "The epidemiological scenarios of hepatitis E virus (HEV) and hepatitis A virus (HAV) infections have changed in the last few decades, but precise epidemiological data on the prevalence of anti-HEV and anti-HAV, alone or in combination, in the general population are scanty. "
11/15/2016 - "In the remaining 105 children, immunization resulted in anti-HAV levels of 17-572 mIU/mL. Based on the ≥15% annual infection risk, an estimated 60% of children were exposed to HAV encounters during follow-up. "

06/01/2012 - "The aim of the present study was to investigate the seroprevalence of Hepatitis A virus antibodies in patients with clinical symptoms of viral hepatitis and molecular characterization of the detected isolates. "
04/01/2007 - "Patients with the main diagnosis other than hepatitis were screened and 71 % of them were found positive for anti-HCV, 57 % for anti-HBc total and 32 % for anti-HAV total. "
07/01/2005 - "Logistic regression analysis demonstrated a positive correlation of positive anti-HAV test with age, non white color of the skin, absence of sewage treatment and domestic water filter, and a past history of hepatitis. "
06/01/2001 - "The total rate of positive for anti-HAV and anti-HEV was 55.2% (112) in 203 patients with acute hepatitis, 22.2% (45) and 33% (67) were positive separately for anti-HAV and anti-HEV in 112 patients. "
10/15/1994 - "86.3% (CI 95% = 83-93) of the positive anti-HAV subjects reported not having had clinical history of hepatitis. "

01/01/2002 - "Anti-HAV antibody testing was performed on blood samples from a hepatitis B and C study conducted among street youth in 1995-96. "
12/01/2011 - "We used multivariable linear regression to assess the sex-specific, adjusted associations of 'childhood' pathogens [0 (n = 1002), 1 (n = 2199), 2 (n = 3442) or 3 (n = 4833) of HSV1, CMV and hepatitis A antibodies] and 'adult' pathogens [0 (n = 5836), 1 (n = 3018) or ≥ 2 (n = 720) of HSV2, HHV8 and hepatitis B or C) with waist-hip ratio (WHR) and body mass index (BMI) standard deviations (SDs) using NHANES III (1988-94). "
03/01/2008 - "Reflex testing of anti-HCV reactive sera for anti-HAV and hepatitis B surface antibody can facilitate appropriate follow-up and timely immunization. "
06/01/2007 - "A past history of injecting drug use was significantly associated with markers for hepatitis B and C; age predicted presence of anti-HAV. "
10/01/2006 - "Prevalence of anti-hepatitis B and anti-hepatitis A antibodies among school aged children in Western Saudi Arabia."

01/01/1982 - "The present study suggests the possibility that the deposition of immune complexes of HAV and anti-HAV antibody in the liver cell plays an important role in the pathogenesis of massive liver cell necrosis in fulminant type A viral hepatitis."
03/01/1995 - "Severe hepatic lesions such as piecemeal necrosis and bridging necrosis were detected during the acute phase, coinciding with the maximum transaminase levels and the appearance of anti-HAV antibodies. "
07/01/1997 - "We have tested for serum anti HAV IgG 194 chronic hepatitis patients from Naples to evaluate the level of protection against HAV in a category of patients in whom an acute necrosis due to HAV might induce liver failure. "
