Rell said results from a Southbury resident were inconclusive for H1N1 flu and that further testing was planned by the CDC.

The state Department of Public Health has identified 13 other probable cases of H1N1 flu in Connecticut, five of which are students at Fairfield University.

Samples from the non-confirmed cases were tested at the Department of Public Health laboratory and determined to have a strain of influenza other than the seasonal flu.

The virus has been confirmed in 21 states and a total of 160 cases had been identified in the U.S. One death was reported in Texas.

Take Precautions, Health Officials Say

Health officials said the symptoms of H1N1 are similar to typical seasonal influenza and may include fever, cough, sore throat, chills, headache, body aches and fatigue.

With no vaccine currently available for H1N1 influenza A, Connecticut residents have been encouraged to:

Wash their hands frequently with soap and water for at least 20 seconds, especially after sneezing or coughing.

Cover their mouths and noses with a tissue or sleeve when sneezing or coughing.

Avoid close contact with individuals experiencing flu-like symptoms.

Contact a physician if symptoms develop and avoid close contact with others as much as possible.

Stay home from work or school to avoid infecting others.
