*HEV, hepatitis E virus; SCR, signal/cutoff ratio; NT, nontraveler; NA, not applicable (quantitative reverse transcription PCR not done); –, HEV not detected or genotype not tested; Neg, negative.
†In genome-equivalents/mL.
‡Within 2 mo before illness or visit to physician.
§Fulminant hepatic failure developed but resolved (14).
¶Fulminant hepatic failure developed; patient died at time of liver transplantation (14).
#Initial illness was meningitis.
**Asymptomatic; tested for HEV because of recent miscarriage.
††Fulminant hepatic failure developed, requiring liver transplantation; patient survived.
