Dental care associated with an outbreak of HIV infection among dialysis patients Atención dental asociada con un brote de infección por VIH en pacientes sometidos a diálisis
An outbreak of 14 cases of human immunodeficiency virus (HIV) infection was discovered by chance in May 1993 among hemodialysis patients at a university hospital in Bucaramanga, Colombia. The outbreak occurred in 1992. Stored sera were used to establish the probable period of infection (PPI) for 10...
