In pregnancy which viral infection has maximum moality?

HEV hepatitis is an enterically transmitted, waterborne infection occurring primarily beyond the years of infancy. HEV is endemic in India where it is caused by fecal con- tamination of drinking water. Prevalence rates of anti-HEV IgG antibodies approach 40% in the Indian population. Epidemics have been repoed from Asia, sub-Saharan Africa, and Mexico. Sporadic infection seems to be uncom- mon; it is seen mainly in travelers and accounts for more than 50% of cases of sporadic acute viral hepatitis in India. In most cases, the disease is self-limited; HEV is not associated with chronic liver disease or persistent viremia. A characteristic feature of the infection is the high moality rate among pregnant women approaching 20% ref Robbins 9/e p 619
