[Prevalence of human herpesvirus 7 in Mexican blood donors].
The human herpes virus 7 (HHV-7) has been recently isolated from CD4 cells of healthy persons. The present study describes the antibody prevalence of this virus in a healthy Mexican population. Two hundred blood samples from candidates for blood donation at the Hospital General de Mexico were studied with the indirect immunofluorescence test (IFA) in HHV-7 infected SupT1 cells. The testing was done in the University of Cologne, Germany; 167 were males and 33 female; the donors came from 12 of the 31 states in the Mexican republican, predominantly from Mexico City (60.5%) and the State of Mexico (28%). Their mean age was 29.2 years. All but three samples were positive to the HHV-7 (98.5% positivity). Nearly 85% had high titers (> or = 1:80). Other serology testing in the samples revealed 1% positive tests to hepatitis B, 2% to syphilis, and 0.5% to brucella. Hepatitis C and the HIV test were negative in all. The high prevalence of HHV-7 in our donor population should be further studied in order to determine titers indicative of an active infection and of their association with illnesses.
