Answer

No sex preponderance occurs with HCV infection. [5]

In the United States, 65% of people with HCV infection are aged 30-49 years. Those who acquire the infection at a younger age have a somewhat better prognosis than those who are infected later in life. Infection is uncommon in persons aged 20 years and younger but is more prevalent in persons older than 40 years. [31, 32] Data suggest that an association exists between age and transmission route, such as nonsterile medical procedures, including vaccination and parenteral drug treatment. [33]
