Hepatitis B virus (HBV) infection is a serious global public health problem. The infection may be transmitted through sexual intercourse, parenteral contact or from an infected mother to the baby at birth and, if contracted early in life, may lead to chronic liver disease, including cirrhosis and hepatocellular carcinoma. On the basis of the HBV carrier(More)
A total of 202 serum and stool samples from acute hepatitis patients attending the Fever Hospital of Alexandria, Egypt, have been studied to reveal markers of hepatitis virus infection. Anti-HAV IgM were detected in 21 out of 202 sera (10.4%), whereas 201 sera (99.5%) had anti-HAV IgG. The first age attack was in the class-age 0–9 years with 64.7% of(More)
Hepatitis A is the most common form of acute viral hepatitis in the world. Major geographical differences in endemicity of hepatitis A are closely related to hygienic and sanitary conditions and other indicators of the level of socioeconomic development.

Since 2006, the availability of anti-RV vaccines has deeply modified the incidence and economic burden of RV infection. In Europe, some countries have introduced an anti-RV vaccination program in the last 10 y. Although community(More)

Prevalence of Herpes Simplex, type 2, specific antibodies was estimated in sexually transmitted disease outpatients: 783 heterosexuals and 158 homosexual-bisexuals. The anti-HSV-2 prevalence rates were 69% in the homosexual-bisexuals and 35% in the heterosexuals. In both groups positive association with age of anti-HSV-2 prevalence was found: only in the(More)
A total of 213 subjects from a community in Italy of immigrants from Somalia and other NE African countries were enrolled in this study to evaluate the prevalence of HAV, HBV, HCV and HDV infections and to assess their possible risk factors. Of the subjects, 45 per cent (96) were female and 24 per cent (52) were under 12 years old. The age range was from 1(More)
The hepatitis B virus (HBV) and hepatitis Delta virus (HDV) infection rates were estimated in patients attending a venereal disease outpatient clinic: 759 heterosexuals and 154 homosexual-bisexual men. The anti-HBC prevalence was higher in homo-bisexual men (68.8 per 100) than in heterosexuals (41.8 per 100), whereas HBsAg was roughly the same in the two(More)
