Q fever outbreak in Cheltenham, United Kingdom, in 2007 and the use of dispersion modelling to investigate the possibility of airborne spread.

چکیده
We describe the investigation of an outbreak of Q fever in the town of Cheltenham, England. The outbreak was detected in June 2007, and prospective and retrospective case finding identified 30 confirmed or probable human cases. The investigation identified windborne spread of Coxiella burnetii from nearby sheep farms as the most likely source of infection. A telephone survey was conducted to identify risk practices at local farms. Subsequently the atmospheric dispersion model NAME was used to identify whether air from the identified farms with high risk practices had been carried into Cheltenham town centre during the risk period. Three high risk farms were identified and the modelling showed that air from all of these farms was carried over Cheltenham in the estimated risk period. The investigation resulted in an information campaign to farmers and production of improved advice for livestock farmers on reducing the risks of transmitting Q fever to humans.

Query fever: an opportunity to understand the disease better.
This week’s issue of Eurosurveillance presents two articles on Q fever. A surveillance report about a Q fever outbreak in Cheltenham, United Kingdom (UK), describes the traditional pattern of Q fever epidemiology involving clusters of cases reported around farms with infected animals (sheep, goats) [1]. The second article provides an update on a long-lasting and ongoing Q fever outbreak with a ...

Effect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems
In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...
متن کاملQ fever a Forgotten Disease in Iran
There have already been a few studies on Q fever in Iran and most of them go back to more than 50 years ago. Preliminary serologic studies on ruminants and febrile patients in Southeast Iran show a high seropositivity in this region. Misdiagnosis as well as poor attention of public health authorities to this infection can facilitate the epidemic spread of Q fever. Further studies on the diagnos...
متن کاملMaking Research Matter; Comment on “Public Spending on Health Service and Policy Research in Canada, the United Kingdom, and the United States: A Modest Proposal”
We offer a UK-based commentary on the recent “Perspective” published in IJHPM by Thakkar and Sullivan. We are sympathetic to the authors’ call for increased funding for health service and policy research (HSPR). However, we point out that increasing that investment – in any of the three countries they compare: Canada, the United States and the United Kingdom– will ipso facto not necessarily lea...
