Drug resistance within HIV-1 transmission cluster. (a) Drug resistance within HIV-1 transmission clusters for different subtypes. (b) The study population was stratified into three age-based cohorts. The left column presents the prevalence of resistance to various ARVs among individuals within the TDR molecular transmission cluster. In contrast, the right column shows the prevalence of resistance to the same ARVs in individuals excluding those from the TDR molecular transmission cluster
