Date of first confirmation of the event: 20 December 2005.
Date of start of the event: 19 December 2005.
During the period under report, there were no active foot and mouth disease outbreaks in the country and there were no suspected outbreaks under investigation.
In view of the favourable evolution of the epidemiological situation and the results of the epidemiological surveillance activities (screening, inspection, serological testing and additional studies), which indicate that the infection has not spread, the animal health emergency measures have been lifted.
Movement restrictions on susceptible animals have been relaxed but control measures are still in force in the farm where the outbreak occurred.
The epidemiological survey did not reveal any additional cases within a 10-km radius of the outbreak or in any other part of the country.
Final report: yes.
Continuing notification using the six-monthly report: yes.
