Beaver fever closes New York spring; 6 sick from giardia

The Times Union reports the Rensselaer County Health Department closed a spring Friday after six people became sick with "beaver fever” after drinking water obtained from the site.

Residents are advised not to drink water from a spring located one-quarter mile north of the intersection of routes 22 and 43.

The intestinal illness is caused by a microscopic parasite called Giardia lamblia.
