About Acellular Life
Viruses are acellular infectious particles whose capsid, nucleic acid and host-dependent replication distinguish them from living cells. HIV infection covers transmission, replication, effects on helper T cells, progression to AIDS, symptoms, prevention and treatment, while AIDS is the disease state caused by advanced immune-system damage rather than a separate virus.
