Tamiflu's ability to cure questioned

NORTH CAROLINA (WIVB) - Medical investigators are in North Carolina, to learn more about H1N1 Tamiflu resistant cases.

The seriously ill patients were all housed at Duke University Medical Center's Cancer ward.

They had been given Tamiflu to prevent them from getting ill, but recent tests show the virus mutated despite those treatments.

Three of the four patients have died.

"The vast majority of people infected with influenza do not even receive antiviral treatments, so this mutation treatment is a moot point to most of us. However, it is something we have to pay attention to when we see it."

The Swiss-made Tamiflu is one of two medicines used in the U.S. to fight the pandemic.
