Control of many infectious diseases relies on the detection of clinical cases and the isolation, removal, or treatment of cases and their contacts. The success of such "reactive" strategies is influenced by the fraction of transmission occurring before signs appear. We performed experimental studies of foot-and-mouth disease transmission in cattle and estimated this fraction at less than half t...
* there is very little interchange of information between individual countries in this respect. The Center therefore decided to review the status of these diseases and their control, and in order to provide a basis for comparison the period of 1 October 1952 to 30 September 1953 was selected. Much historical information will thus be omitted but it is hoped that a similar review may be prepared ...
Foot and mouth disease (FMD) in cattle is usually clinically obvious in the unvaccinated herds of countries in which the disease occurs only occasionally. However, in vaccinated herds and in some breeds indigenous to areas in which FMD is endemic, the disease may circulate undetected.
Livestock movements in Great Britain (GB) are well recorded and are a unique record of the network of connections among livestock-holding locations. These connections can be critical for disease spread, as in the 2001 epidemic of foot-and-mouth disease (FMD) in the UK. Here, the movement data are used to construct an individual-farm-based model of the initial spread of FMD in GB and determine t...
Hand, foot and mouth disease in China: evaluating an automated system for the detection of outbreaks
OBJECTIVE To evaluate the performance of China's infectious disease automated alert and response system in the detection of outbreaks of hand, foot and mouth (HFM) disease. METHODS We estimated size, duration and delay in reporting HFM disease outbreaks from cases notified between 1 May 2008 and 30 April 2010 and between 1 May 2010 and 30 April 2012, before and after automatic alert and respo...
Foot and mouth disease (FMD) causes substantial economic losses to the predominantly agricultural community of the Kingdom of Nepal. FMD is endemic in the country and four of the seven serotypes of FMD virus have been isolated (O, A, C and Asia 1). The epidemiology of FMD and the factors which play a role in its prevalence and spread are outlined. The National Epidemiological Laboratory for FMD...
Since 2001 models of the spread of foot-and-mouth disease, supported by the data from the UK epidemic, have been expounded as some of the best examples of problem-driven epidemic models. These claims are generally based on a comparison between model results and epidemic data at fairly coarse spatio-temporal resolution. Here, we focus on a comparison between model and data at the individual farm...
