Influenza and human immunodeficiency virus infection: absence of HIV progression after acute influenza infection

Abstract

Influenza is a major cause of morbidity for people with significant underlying disease, but the impact of influenza on people infected with human immunodeficiency virus (HIV) remains unclear. We studied a population of HIV-infected adults during the 1998-1999 influenza season to see whether influenza had any adverse effects on the course of HIV infection. During 5 months of follow-up, we found no unique clinical manifestations or negative impact on CD4(+) cell count, virus load, or clinical progression of HIV disease. Although half of our cohort received antibiotic therapy, none received specific anti-influenza therapy and none required hospitalization. Acute influenza does not appear to be a risk for progression of HIV disease.
