As of 28 October 2013, six cases of wound botulism have been reported in Norway among people who had injected heroin (most reported intramuscular injection of heroin) in the region of Oslo.
The source of infection is thought to be a batch of contaminated heroin. The geographical distribution of the potentially contaminated heroin is unknown at this time, as is the distribution stage at which the heroin may have been contaminated.
So far, no cases of botulism in heroin users in Belgium have been reported. Also, there are no indications that this contaminated batch of heroin is present on the Belgian market.
Guidelines on drug treatment, prevention and control of infections among injecting drug users have recently been issued by ECDC and the EMCDDA. The two agencies will continue to monitor the evolution of this situation in terms of the epidemiological information available.
