State Epidemiologist Megan Davies, MD, has issued a memo to all NC health care providers about the use of oseltamivir for treatment of H1N1 influenza virus infections.  The memo was prompted by a cluster of infections involving oseltamivir-resistant H1N1 influenza among patients on a single hospital ward in North Carolina.  The cases are not related to three cases of oseltamivir-resistant H1N1 influenza infections previously identified in the state.  Read Dr. Davies’ memo here.
