Cluster of Invasive Group A Streptococcus Infections

October 31, 2016

Key Points and Recommendations:

  • The New Hampshire Division of Public Health Services (NH DPHS) has been notified of four cases of invasive group A streptococcal bacteremia, all males, and all active injection heroin users from Southern/Central New Hampshire, who presented to healthcare in the last 10 days.

  • It is unclear if these cases are connected; however, injection drug use is a risk factor for invasive bacterial infections, including group A streptococcus. NH DPHS is investigating further to determine if these infections are related.

  • We are requesting that healthcare providers ask patients with invasive group A streptococcal infections about any illicit injection drug use history, in particular heroin use, and report cases to the NH DPHS at 603-271-4496 (after hours, 603-271-5300).

For any questions regarding the contents of this message, please contact the NH Department of Health and Human Services, DPHS, Bureau of Infectious Disease Control at 603-271-4496 (after hours, 603-271-5300).
