Pathogens commonly found in category 3 water damage are in a liquid state. The primary biohazard present in a sewage spill are viruses, bacteria and parasites.
Viruses: Primary Sewage Biohazard
Viruses do not reproduce, instead they multiply via a process called replication. After attaching to a host cell, the virus then injects the cell with a genetic material known as Ribonucleic acid (RNA). Within the cell walls the virus replicates, exhausting the cells resources and generating abundant copies of itself. The colony ultimately causes the cell to perish and rupture, releasing the viral progeny to attack healthy cells. The primary route of viral infection from a sewage spill is ingestion. Read more
