Multiple round bumps on cell surface represent sites of assembly and budding of virions. Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. RNA genomes and viral proteins, using host cell resources, that are packaged and released from the cell as new virus particles that will begin the replication cycle anew. Two types of HIV have been characterized: HIV-1 and HIV-2.

The lower infectivity of HIV-2 compared to HIV-1 implies that fewer of those exposed to HIV-2 will be infected per exposure. HIV is different in structure from other retroviruses. A matrix composed of the viral protein p17 surrounds the capsid ensuring the integrity of the virion particle. The density is high as the glycans shield the underlying viral protein from neutralisation by antibodies.
