This part of people aged from 60 to 75 years old constitutes 9.4%. This study showed that the waterway was the dominant way of HA transmission. The course of the disease in most hospitalized patients was typical and cyclic, with a predominance of a mixed variant of the pre-jaundice period and jaundice. One third of patients survey that they had fever, which persisted with jaundice.
