Abstract
An outbreak of hepatitis A, affecting 183 people, occurred in Valencia (Spa in). Epidemiological evidence pointed to an association of the outbreak wit h consumption of Coquina clams (Donax sp), imported frozen from Peru. Shell fish were analysed for the presence of hepatitis A virus (HAV), enterovirus es, rotaviruses, astroviruses, caliciviruses and hepatitis E virus. HAV was detected in 75% of assayed shellfish samples. Other enteric viruses were o ccasionally found in the same samples. Molecular epidemiological analysis o f fragments of the VP1 /2A and the 5 ' end of the genome from shellfish and sera isolates, revealed the presence of six variants belonging to a single genotype.
