Dear He Jing,

The Shanghai hepatitis A outbreak is certainly the largest and most
shocking of its kind.

The problems of raw bivalve mollusk consumption and biological
pollution are discussed at <http://www.jaxshells.org/mollusks.htm>.
We Americans are very fortunate to be relatively insulated from
epidemics like the one you witnessed.
