“…Perhaps surprisingly, in most published accounts of hospital outbreaks, anal or vaginal carriers have been the source of infection [36][37][38][39][40][41][42][43][44]. Anal and vaginal swabs were not collected from theatre staff in this investigation.…”
SUMMARYWe describe the first cluster of cases of necrotizing fasciitis (NF) in this century in the United Kingdom (UK). Between 1 January and 30 June 1994 there were six cases (five confirmed, one probable) of Streptococcus pyogenes NF in west Gloucestershire, population 320000. Two cases died. The first two patients probably acquired their infections during the course of elective surgery performed in the same operating theatre, possibly from a nasopharyngeal carrier amongst the theatre staff. The remaining infections were community-acquired. Of 5 S. pyogenes isolates there were 2 MI strains, 1 M3, 1 M5 and 1 M non-typeable strain. S. pyogenes NF had not been recorded in west Gloucestershire in the preceding 10 years and the incidence of S. pyogenes bacteraemia in England and Wales had not risen in the past 5 years.The two presumably theatre-acquired infections raised several issues. The need for detailed bacteriological investigation of all cases of post-surgical NF was confirmed. Clusters of S. pyogene8 infection following surgery should be managed by closure of the operating theatre until all staff have been screened for carriage. Closure of an operating theatre and screening of staff following a sporadic case is probably not justified because of the infrequency of surgical cross-infection with S. pyogenes. Regular. routine screening of theatre staff is neither practical nor necessary.

“…Multiple nosocomial outbreaks of group A hemolytic streptococcus have been described ( Typically, personnel who served as the index case were asymptomatic. 35,37,[39][40][41]46,49,70,80 During outbreaks, active surveillance has revealed additional personnel colonized by the epidemic strain ( Table 2). Hospital personnel have developed clinical infections as secondary cases ( Table 2).…”

“…The possibility of true airborne transmission has been suggested by several investigators. 33,36,40,41,47,50,52,54 Investigators have demonstrated that rectal or vaginal carriage by healthcare personnel can lead to airborne contamination when changing clothes or exercising. 35,40,41,52 Rectal or vaginal carriage also can lead to transient scalp contamination, which in turn may lead to contamination of wound sites during surger y.…”

Section: Evaluation and Management Of Healthcare Workers With Pharyngmentioning
The group A streptococcus may cause pharyngitis, rheumatic fever, streptococcal toxic shock syndrome, and serious skin and soft-tissue infections. More than 50 nosocomial outbreaks have been reported since 1966. For this reason, healthcare facilities should develop policies for the diagnosis and treatment of symptomatic hospital employees, and for the recognition and management of potential outbreaks. The clinical diagnosis of streptococcal pharyngitis is unreliable. Rapid streptococcal tests may be used for initial screening, but a negative rapid test should be confirmed with a properly obtained culture. Penicillin remains the treatment of choice, but new alternatives now include a 5-day course of either azithromycin or cefpodoxime.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
