Prevention of viral transmission in HD units: the value of isolation.

We have investigated the influence of isolation of patients with different viral serology status on the transmission of viral hepatitis among patients on hemodialysis (HD). Our kidney center was designed to facilitate isolation of infected patients and implement infection control pre-cautions. These included separate rooms, separate entrances and exit sites, and designated HD machines for patients with hepatitis B, hepatitis C, and sero-negative patients.
