The Strep-EURO project (http://www.strep-euro.lu.se/) collects data on severe group A streptococcal (GAS) disease in Europe. It was launched in September 2002 to improve understanding of severe GAS disease in Europe so that an integrated picture of these infections can be achieved and consists of over 50 members from 11 European countries. We briefly summarise below progress on the project to date, including some preliminary results from the participating countries: Germany, Cyprus, Czech Republic, Denmark, Finland, France, Greece, Italy, Romania, Sweden, and the United Kingdom.
