Michael Houghton

Sir Michael Houghton is a British scientist and Nobel Prize laureate. Along with Qui-Lim Choo, George Kuo and Daniel W. Bradley, he co-discovered hepatitis C in 1989. He also co-discovered the hepatitis D genome in 1986. The discovery of the hepatitis C virus (HCV) led to the rapid development of diagnostic reagents to detect HCV in blood supplies, which has reduced the risk of acquiring HCV through blood transfusion from one in three to about one in two million. It is estimated that antibody testing has prevented at least 40,000 new infections per year in the US alone and many more worldwide.
