CHAPTER DMinimal surveillance requirements

3.Points values and point targets

Surveillance samples must meet the point targets set out in Table 2, on the basis of point values fixed in Table 1. All clinical suspects shall be investigated, regardless of the number of points accumulated. A country shall sample at least three out of the four sub-populations. The total points for samples collected shall be accumulated over a period of a maximum of seven consecutive years to achieve the target number of points. The total points accumulation shall be periodically compared to the target number of points for a country or region.
