The Gaza Strip borders the southern part of Israel and Egypt. There is a remarkable difference in the prevalence of antibodies to hepatitis C virus (HCV) between Israel (0.5%) and Egypt (10%). A few thousand inhabitants cross the borders daily from the Gaza Strip to both countries. ⋯ HCV prevalence in the Gaza Strip was found to be 2.2%, relatively higher than in Israel but lower than in Egypt. The most common genotypes found were type 1 b in Southern Israel and type 4 in the Gaza Strip, corresponding to the most prevalent genotype in Egypt. Similarity between type 4 isolates from the Gaza Strip and Egypt was illustrated further by sequence analysis of the HCV 5' noncoding region (NCR).
