Deadly fish virus spreads in Northeast

[GLF]

The hemorrhagic septicemia strain poses no threat to humans

A deadly virus found in two fish species in the northeastern United States last month appears to have spread to two more species, scientists said today.

Meanwhile, hundreds of fish in Lake Ontario and the St. Lawrence River have died in recent weeks, but officials are not yet sure if the newfound virus is behind the kills.

Last week, an estimated 1,000 dead fish washed up on the shores of Lake Ontario in just one morning.
