Intra-host dynamics of viruses with multiple tropism is analyzed with the framework of network dynamics, and its RO-centrality analysis revealed the optimum intervention strategy that typically recommends extremely focused intervention to the most amplifying tissue.\n\nComparing the time series data of infection experiments that excluded cell-to-cell infection of HIV-1 and those with both cell-to-cell and cell-free infections, we quantified their relative contributions to the basic reproductive number of viruses. Infection experiments using polymorphic HIV restriction factor A3H reveals the roles of A3H restriction + type and this counteracting Vif type have played in the coevolutionary dynamism between and
