Survival and recovery of seeded HIV in water and wastewater.
Acquired Immunodeficiency Syndrome (AIDS) is one of the major public health concerns in the world today.
The Human Immunodeficiency Virus (HIV), the causative agent of AIDS, has been isolated from blood, semen, and other body fluids as well as excretions from infected individuals as both free virions, cell-free virus, and as productively infected cells, cell-associated virus.
These body fluids and excretions, when discharged into wastewater collection systems, may contribute to the presence of HIV in wastewater.
This raw wastewater, which may contain HIV, passes through wastewater treatment systems and may pose a potential health threat to wastewater treatment plant workers.
The objectives of this research were to develop a better understanding of the survival of cell-associated HIV in wastewater and to develop reliable methods for the concentration and recovery of HIV from wastewater.
Casson et al. (1992) reported survival of cell-free HIV in primary and secondary effluent<12 h followed by a reduction in titer 1-to 2-log in 24-48 hr.
The infectivity of cell-associated HIV was observed to be reduced rapidly after exposure to distilled water.
However, a subpopulation of cell-associated HIV was observed to remain stable through 48 h and remain infectious for ¾96 h in distilled water.
Preliminary results indicate that cell-associated HIV infectivity in nonchlorinated secondary effluent was less stable than in distilled water. (...)
