Eight patients in the ANRS PRIMO cohort experienced early spontaneous viral control. Viral control was established a median of 6.2 months after primary human immunodeficiency virus type 1 infection and lasted a median of 4.1 years. Seven of the patients initially had detectable viral replication. For 4 patients, viral control was lost during follow-up.
