We report the first case, to our knowledge, of antibody‐negative human immunodeficiency virus type 1 (HIV‐1) subtype C infection, which was identified during screening for acute HIV‐1 infection in Botswana. Results of tests for HIV‐1 antibodies were consistently negative, including rapid and regular enzyme‐linked immunosorbent assay and Western blot. The nonrecombinant HIV‐1 subtype C infection was confirmed by viral genotyping within the gag, pol, and env genes. The period between referral of the patient in a clinically stable condition and AIDS‐related death was
3 months. The reported case indicates the importance of studying the prevalence of seronegative HIV‐1 infection in southern Africa, where subtype C predominates.
