Stable frequency of HIV-1 transmitted drug resistance in patients at the time of primary infection over 1996–2006 in France

Background: Transmission of drug-resistant variants is influenced by several factors, including the HIV-1 RNA levels in HIV-1 -infected patients. Our study describes the transmitted drug-resistant virus among 1446 French patients diagnosed at the time of primary infection and included from 1996 to 2006 along with the proportion of chronically infected treated patients in the French Hospital Database on HIV (FHDH). Methods: Genotypic resistance tests were performed at the time of primary infection. The proportion of patients with viral load
