Recently, Swedish King Carl XVI Gustaf, conferred the Stockholm Water Prize on US scientist Rita R Colwell for her pioneering research on prevention of waterborne diseases. Colwell, a scientist with the University of Maryland and John Hopkins University in Stockholm, has made outstanding contributions to control the spread of cholera which affects some five million people worldwide and causes deaths to an estimated 120,000 people annually. She was joined by 17 previous Stockholm Water Prize laureates and hundreds of water experts at the City Hall of Stockholm.
