Introduction: HIV, the hum.n im.unodeficiency virus. is.the etiological agent of acquired im.unodeficiency s.ndrom. (AIDs.. The aim.of this.s.udy was.to as.es. the evolution of the viral load in patients.under treatm.nt. m.thodology: This.was.a s.udy carried out from.July 2017 to June 2022 at the Point G Univers.ty Hos.ital laboratory. The determ.nation of the viral load of patients.was.carried out by PCR on the ABOTT m.000s./rt platform. Res.lts. A total of 129 patients.infected with HIV-1, aged 19 to 72 years.with a m.an age of 40.05 years.± 10.71;all on antiretroviral chem.therapy. The fem.le gender predom.nated am.ng our patients. The m.s. com.on treatm.nt regim.n was.2INTI + 1INNTI with 72.9% followed by 2INTI + 1INI with 13.2%. As.for the com.inations.of m.lecules. the com.ination TDF + 3TC + EFV and TDF + 3TC + DTG predom.nated, res.ectively 65.1% and 13.2%. 89.9% of our patients.had undetectable virem.a after 12 m.nths.of treatm.nt (p m.681315.65 copies.m. ± 1616908.484 to m. at 5742.36 copies./m. ± 35756.883 at m.2 (p Conclus.on: Generally s.eaking, antiretroviral treatm.nt had contributed to controlling viral loads. however the therapeutic com.ination TDF + 3TC + DTG had m.de it pos.ible to obtain m.re patients.with undetectable virem.a ins.ead.
