No additional cases of Tamiflu-resistant H1N1 flu have been found at Duke University Hospital, according to preliminary results of extensive testing and screening, officials announced Tuesday.
On Nov. 20, the hospital reported that four patients in a single, isolated unit were confirmed as having Tamiflu-resistant H1N1 swine flu. The unit is for patients with seriously impaired immune systems and multiple other complex medical conditions.
Over the past 10 days, all patients in the unit were tested several times by the hospital, the U.S. Centers for Disease Control and Prevention and the North Carolina Division of Public Health. No new cases of Tamiflu-resistant H1N1 were found.
The hospital is working with the CDC and state health officials to review the initial four reported cases. It's expected the assessment will continue for several more weeks.
