Dr. Jeffrey Engel, the state health director, said officials are involuntarily isolating patients who may have the virus. But he said the handful of suspected cases are sporadically located in various parts of the state.
"We're working very closely with providers, and they are investigating cases on a daily basis," Engel said. "It's a very fluid situation and there will be suspect cases. People travel all the time."
Investigators were gathering specimens and hope to know whether the cases are "probable" some time Tuesday and Engel said they will seek confirmations by Wednesday.
