*Changes in serologic status were indicated by changes in IgG anti-HEV seroprevalence observed in 2003 and 2004, percent and number (n) of seronegative participants undergoing positive seroconversion (PC), and that of seropositive persons undergoing negative seroconversion (NC). Linyun has significantly higher PC (p<0.01). |
