The table shows a breakdown by year of number of samples from suspected measles cases identified through the national measles and rubella surveillance system during 2007–2011. Samples received at the National Measles Laboratory in good condition were tested first for measles and the numbers that were positive along with their percentages (%) are indicated. Samples that were negative for measles were subsequently tested for rubella and the total positives, together with their percentages (%) are also indicated. In 2007, for example, only 1 (0.4%) of 242 samples tested for measles at the laboratory was positive. Of 241 measles negative samples, 106 (44%) were positive for rubella.
