1 THOMSON REUTERS INTEGRITY SM INFLUENZA A: A New Challenging Opportunity for Market Impact

THOMSON REUTERS INTEGRITY: SUMMARY This use case will focus on Influenza A and, specifically on Oseltamivir Phosphate (Tamiflu®), a currently available drug being used to treat this challenging disease. It will also demonstrate how to analyze current synthetic approaches to this compound, looking for new opportunities for chemical intermediate and reagent producers.

THOMSON REUTERS INTEGRITY: INFLUENZA Influenza is highly contagious acute viral infection of the respiratory tract causing the flu, a disease with symptoms that include fever, myalgia, headache, malaise, cough, sore throat, rhinitis and other common cold-like symptoms Influenza A (H1N1) and the 2009 Influenza Pandemic Swine influenza (swine flu) is a respiratory disease of pigs caused by type A influenza virus that regularly causes outbreaks of influenza in pigs. The incidence of swine flu in humans is normally quite low. In spring 2009, however, an outbreak occurred in Mexico and spread quickly to parts of the U.S., with other travel-related cases reported soon thereafter in various European and Asian countries. A new strain of the H1N1 virus is responsible for these cases. The 2009 influenza pandemic has spread internationally with unprecedented speed. The World Health Organization reports that as of November 22, 2009, more than 622,480 laboratory- confirmed cases of influenza A (H1N1) infection, including at least 7,826 deaths, have been officially registered in at least 207 countries worldwide. The influenza A (H1N1) virus is susceptible to treatment with the neuraminidase inhibitors oseltamivir (Tamiflu) and zanamivir (Relenza), but not to amantadine or rimantadine.
