N Engl J Med. Hepatitis E is hspatitis through the fecal oral route and outbreaks are usually associated with contaminated water supplies in countries with poor sanitation. Persons newly infected with HCV are usually asymptomatic, so acute Hepatitis C is rarely identified or reported.

Good sanitation measures are essential for preventing environmental contamination. Roger Detels – Epi Feb Published by Buck Williams Modified over 3 years ago. Persons with chronic HBV infection require medical evaluation and regular monitoring to determine whether disease is progressing and to identify liver damage or hepatocellular carcinoma.

HEV is the sole member of the genus Hepevirus. Spontaneous conversion from e antigen to e antibody a change known as seroconversion is a predictor of long-term clearance of HBV in patients undergoing antiviral therapy and indicates lower levels of HBV.
