a) Randomized sero-surveys surveys (cont.)<br />

Field procedures and sample<br />

sizes<br />

1) Annual sample sizes shall be sufficient to provide 95%<br />

probability <strong>of</strong> detecting evidence <strong>of</strong> rinderpest if present at a<br />

prevalence <strong>of</strong> 1% <strong>of</strong> herds or other sampling units and 5%<br />

within herds or other sampling units. This can typically be<br />

achieved by examining 300 herds per stratum per year, but<br />

procedures <strong>for</strong> sampling should be in accordance with the<br />

“Guide to Epidemiological Surveillance <strong>for</strong> <strong>Rinderpest</strong>”, or<br />

another procedure that would achieve the same probability <strong>of</strong><br />

detection.<br />
