Abstract
Summary
Hepatitis C is a contagious liver disease caused by
HCV , sub-Saharan Africa has the highest prevalence of HCV
infection worldwide 5.3%.
Egypt is among the world highest prevalence rates of
HCV infection 10-15%.
Infection by HCV occurs after exposure to infected
blood or other bodily fluids containing blood, this implies
several possible modes of transmission including parenteral
transmission ,sexual transmission and vertical transmission,
Nosocomial procedures are likely the leading source of HCV
transmissions worldwide.
Diagnosis of HCV infection occur by detection of HCV
antibodies in serum by ELIZA and by detection of nucleic
acid RNA of the virus through NAT technology of PCR.
The present study shows frequency of hepatitis C virus
Iinfection among Egyptian blood donors in central blood bank
of Ain Shams hospitals in duration of January to March2013
done on7693 donors.
The prevalence of HCV positive donors equal 4.27% oftotal donors by ELIZA.
The negative donors by ELIZA equal 95.73% of total donors by ELIZA, after doning PCR for them found 2
females positive equal 0.027%.
NAT technology of PCR is faster in HCV detection 15 days in comparison to ELIZA which take several weeks for
detection of antibodies and also more confirmative.
