SURVIVAL OF HUMAN-IMMUNODEFICIENCY-VIRUS IN SUSPENSION AND DRIED ONTOSURFACES

Cell-free and cell-associated human immunodeficiency virus cultures su spended in 10% serum remained infectious for several weeks at room tem perature. The stability was further increased when cell-associated vir us was suspended in neat serum. When dried onto a glass coverslip, vir us remained infectious for several days, although cell-associated viru s lost infectivity more rapidly than cell-free virus.
