More than 16,000 people in Shanghai have contracted hepatitis-A in the worst epidemic of the disease in recent history, health officials there said today.

Officials said the outbreak was caused by contaminated clams harvested from heavily polluted coastal waters. They estimated that 90% of the patients contracted the disease after eating the clams in late December. The infectious disease is caused by a virus and spread in food and water.
