HIV is now known to spread between CD4 + T cells by two parallel routes: cell-free spread and cell-to-cell spread, i.e. it employs hybrid spreading mechanisms. [95] In the cell-free spread, virus particles bud from an infected T cell, enter the blood/extracellular fluid and then infect another T cell following a chance encounter. [95]
The human immunodeficiency viruses (HIV) are two species of Lentivirus (a subgroup of retrovirus) that infect humans.Over time, they cause acquired immunodeficiency syndrome (AIDS), [1] [2] a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.

The within-host dynamics of HIV infection include the spread of the virus in vivo, the establishment of latency, the effects of immune response on the virus, etc. [6] [7] Early studies used simple models and only considered the cell-free spreading of HIV, in which virus particles bud from an infected T cell, enter the blood/extracellular fluid ...
