The World Organisation for Animal Health (OIE) received follow-up report no.3 yesterday, 6 June.
The report shows that a total of 222 cattle were found susceptible to the disease, out of which 19 cases were identified. The 19 infected cattle are within the infected (containment) zone. The increased number of the infected cattle is attributed to movement congregating animals and iatrogenic transmissions associated with vaccination.
No animals were destroyed as a result of the outbreak, and no deaths were recorded.
Extensive surveillance in zone 6 continues to be carried out. The first round of clinical and serological surveillance in small stock started on 17 May 2011 until 5 June 2011. The surveillance targeted crushes where there were clinical cases in cattle. A sample size of 418 for small stock was calculated using “Survey Toolbox” software. Due to small domestic pig population, all domestic pigs will be sampled.
Movement of cloven-hoofed animals of zone 6 origin and their derived fresh products are not allowed within and out of zone 6. 11,882 cattle have been vaccinated with a primary vaccine. Biosecurity measures continue to be in place in zone 6.
The source of the outbreak remains inconclusive.
