This section includes information and resources about Human Immunodeficiency Virus (HIV) for journalists: Boehringer Ingelheim press releases, background information, related press kits and a collection of images and videos.
The human immunodeficiency virus (HIV), the causative agent of AIDS, is a retrovirus. It enters living cells and uses the host cell's replication machinery.
During HIV infection, millions of viral particles are present in the blood stream. They continuously infect cells of the immune system.
The battle between the viral infection and the cells of the immune system continues throughout the course of the infection.
Perinatal transmission of HIV from mother to baby is the major cause of HIV infections in children worldwide.
HIV is able to infect the central nervous system (CNS), including the brain. The CNS has been shown to be a major reservoir of virus.
