Tamiflu-resistant swine flu identified along Texas-Mexico border

PAHO on Monday announced it had found Tamiflu-resistant H1N1 (swine) flu along the Texas-Mexico border, Agence-France Press reports.

"Experts had gathered in La Jolla on Monday to discuss the response to the outbreak, and warned that resistant strains were likely emerging because of overuse of antivirals like Tamiflu," the news service writes (8/3).
