![]() ![]() Self-reported history of injection drug use was recorded for each patient, with drug use corroborated by toxicology results when possible. ![]() All wound botulism patients reported to COSD were asked by investigators about potential exposures using a standardized questionnaire. A probable case was defined similarly, but without laboratory confirmation. ![]() Prompt diagnosis, administration of BAT, and provision of supportive care can help stop the progression of paralysis and be lifesaving.Ī confirmed case was defined as illness in a resident of San Diego County who had 1) clinically compatible signs or symptoms of botulism during September 2017–May 2018 2) laboratory detection of botulinum neurotoxin (BoNT) in serum 3) a history of injection drug use during the 2 weeks before illness onset and 4) no suspected exposure to a contaminated food. Wound botulism is likely underrecognized because of its rarity and the overlapping signs and symptoms with opioid intoxication, overdose, and other neurologic syndromes including Guillain-Barré syndrome, the Miller Fisher variant of Guillain-Barré syndrome, and myasthenia gravis. All patients were treated with heptavalent botulism antitoxin (BAT). Clinically compatible signs and symptoms included muscle weakness, difficulty swallowing, blurred vision, drooping eyelids, slurred speech, difficulty breathing, loss of facial expression, or descending paralysis. All nine were persons who inject drugs seven specifically reported using black tar heroin and six practiced subcutaneous injection known as skin popping. By April 18, 2018, nine (eight confirmed and one probable) patients with wound botulism were identified, all of whom were hospitalized one of the nine died. In collaboration with the California Department of Public Health, COSD conducted an investigation to identify additional cases, determine risk factors for illness, estimate cost of medical care, and develop recommendations to prevent further illness. On October 9, COSD, which had reported an average of one wound botulism case per year during 2001–2016, sent a health alert through the California Health Alert Network, notifying Southern California providers of these two patients, including their signs and symptoms and black tar heroin exposure. 17, 2020.During September 29–October 6, 2017, the County of San Diego Public Health Services (COSD) was notified of two patients with suspected wound botulism and a history of using black tar heroin.

Nuclear, biologic, and chemical agents weapons of mass destruction. Microbiology, pathogenesis, and epidemiology of anthrax. Clinical manifestations and diagnosis of anthrax. Heroin sold in Europe likely comes from areas where naturally occurring anthrax is more common. More recently, in two separate outbreaks, heroin users in Europe contracted anthrax through injecting illegal drugs. Twenty-two people developed anthrax after being exposed to spores sent through the mail, and five of those infected died. One of the few known instances of nonanimal transmission was a bioterrorism attack that occurred in the United States in 2001. In the United States, a few people have developed anthrax while making traditional African drums from the skins of infected animals. Most human cases of anthrax occur as a result of exposure to infected animals or their meat or hides. Common hosts for anthrax include wild or domestic livestock, such as sheep, cattle, horses and goats.Īlthough rare in the United States, anthrax is still common throughout the developing world, in places such as Central America and South America, sub-Saharan Africa, Central Asia and southwestern Asia, southern Europe and Eastern Europe, and the Caribbean. The spores can remain dormant for years until they find their way into a host. Anthrax spores are formed by anthrax bacteria that occur naturally in soil in most parts of the world. ![]()
