On June 2, 2010 a Macomb County, Michigan Circuit Court judge dismissed an October, 2009 charge brought under the state's anti-bioterrorism law against an HIV-positive man, Allen, who was involved in an altercation with a neighbor. The court did agree with a previous Michigan Court of Appeals decision, People v. Odom, supported by information on the CDC website, that HIV-infected blood is a "harmful biological substance" as defined under the bioterrorism law because it is implicated in the transmission of HIV. An assault charge against Allen is still pending.
