Household transmission of hepatitis A virus after infection of the mother

Hepatitis A virus (HAV) can spread among family members through fecal-oral transmission. We report a case of hepatitis A transmission within a family affecting the mother (index case), father, and their three daughters. The viral sequences obtained from the father and two daughters showed a nucleotide similarity ranging from 99.8% to 100%.Prevention of the intrafamilial transmission of HAV infection requires strict adherence to contact precautions and immunization against HAV after diagnosis of the index case, which should have been considered for this family.
