Undetectable Viremia without Antiretroviral Therapy in Patients with HIV Seroconversion: An Uncommon Phenomenon?

Abstract
Background. The objective of this study was to identify the frequency and characteristics of patients with human immunodeficiency virus (HIV) infection who had spontaneously achieved viremia below the detection limit of either 400 or 500 copies/mL (depending on the test used) and to describe the duration of undetectable viremia without antiretroviral therapy (ART).
