T1 - Outbreak among Drug Users Caused by a Clonal Strain of Group A Streptococcus T2 - Emerging Infectious Disease journal PY - 2000 VL - 6 IS - 2 SP - 175 SN - 1080-6059 AB - We describe an outbreak among drug users of severe soft-tissue infections caused by a clonal strain of group A streptococcus of M-type 25. Cases (n = 19) in drug users were defined as infections (mainly needle abscesses) due to the outbreak strain. Comparison with controls showed that infected drug users bought drugs more often at a specific place. Drug purchase and use habits may have contributed to this outbreak.
