In a study to determine the incidence of infection with hepatitis delta virus (HDV) in high-risk groups in Spain, tests to detect serological markers of infection with hepatitis B virus (HBV) and total antibodies against HDV (anti-HDV) were performed in serum samples from 451 unselected intravenous drug addicts and 168 homosexual or bisexual men. Most samples were obtained from primary health care units in Madrid. In drug addicts 87.4% of samples were positive for HBV markers and 15.1% were positive for anti-HDV. However, the incidence of anti-HD was much higher in HBsAg carriers (70.7%) than in individuals positive for anti-HBs (10.4%). Ninety-two samples (54.8%) from homosexual men were positive for HBV markers, but all were negative for anti-HD. Thus, parenteral transmission seems to play a major role in the spread of HDV in Spain, the sexual route being of minor relevance.

D002353	Carrier State	The condition of harboring an infective organism without manifesting symptoms of infection. The organism must be readily transmissible to another susceptible host.

D003698	Hepatitis Delta Virus	A defective virus, containing particles of RNA nucleoprotein in virion-like form, present in patients with acute hepatitis B and chronic hepatitis. It requires the presence of a hepadnavirus for full replication. This is the lone species in the genus Deltavirus.

D003699	Hepatitis D	INFLAMMATION of the LIVER in humans caused by HEPATITIS DELTA VIRUS, a defective RNA virus that can only infect HEPATITIS B patients. For its viral coating, hepatitis delta virus requires the HEPATITIS B SURFACE ANTIGENS produced by these patients. Hepatitis D can occur either concomitantly with (coinfection) or subsequent to (superinfection) hepatitis B infection. Similar to hepatitis B, it is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.

D006509	Hepatitis B	INFLAMMATION of the LIVER in humans caused by a member of the ORTHOHEPADNAVIRUS genus, HEPATITIS B VIRUS. It is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.	Hepatitis B Virus Infection
D006514	Hepatitis B Surface Antigens	Those hepatitis B antigens found on the surface of the Dane particle and on the 20 nm spherical and tubular particles. Several subspecificities of the surface antigen are known. These were formerly called the Australia antigen.	Australia Antigen,HBsAg,Hepatitis B Surface Antigen,Antigen, Australia

D000163	Acquired Immunodeficiency Syndrome	An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.
