| Zusammenfassung |
Foot-and-mouth disease (FMD) is a highly contagious viral disease of cloven-hoofed
domesticated and wild animals. The highly contagious nature of FMD is a reflection of the
wide range of host species, the enormous quantities of virus liberated by infected animals, the
range of excretions and secretions which can be infectious, the stability of the virus in the
environment, the multiplicity of routes of infection and the very small doses of the virus that
can initiate infection.
One of the mechanisms of spread is the carriage of droplets and droplet nuclei exhaled in the
breath of infected animals. Such spread can be rapid and extensive, and it is known in certain
circumstances to have transmitted disease over a distance of several hundred kilometres.
During the 2001 FMD epidemic in the United Kingdom (UK), atmospheric dispersion models
were applied in real time in order to assess the potential for atmospheric dispersion of the
disease. The operational value of such modelling is primarily to identify premises which may
have been exposed so that the human resources for surveillance and disease control purposes
are employed most effectively.
The paper describes the combined modelling techniques and presents the results obtained of
detailed analyses performed during the early stages of the UK 2001 epidemic.
This paper investigates the potential for disease spread in relation to two outbreaks (Burnside
Farm, Heddon-on-the-Wall and Prestwick Hall Farm, Ponteland, Northumberland). A
separate paper (Gloster et al., 2002) provides a more detailed analysis of the airborne disease
transmission in the vicinity of Burnside Farm.
The combined results are consistent with airborne transmission of disease to livestock in the
Heddon-on-the-Wall area. Local topography may have played a significant role in influencing
the pattern of disease spread. |
