Seroprevalencija i faktori rizika za infekciju virusom hepatitisa C u ...

were associated with HCV seropositivity. The prior HBV infection (p=0.002) and
gonorrhea (p=0.011) were the only risk factors significantly associated with anti-
HCV prevalence. No other factors reflecting risk sexual behavior such as sexual
orientation (p=0.355), the number of sexual partners (p=0.318) and the number of
risk factors (p=0.079) were associated with HCV seroprevalence. HCV-RNA was
detected in 73.1% seropositive participants. Three of the seronegative cases
(2.1%) were also found to be HCV-RNA positive (“window period”). The majority of
participants were infected with genotype 1 (55.6%), 38.9% with genotype 3 and
5.6% with genotype 4. The most prevalent subtypes were 1a (38.9%) and 3a
(38.9%). According to the risk groups, in persons with multiple sexual partners all
three genotypes (subtypes 1a and 3a) were detected. MSM were infected with
genotypes 3a and 4, CSW and their clients with genotypes 1a and 3a and persons
with STDs were infected with genotypes 1 (subtypes 1a and 1b) and 3a.
