SINGAPORE - The number of cases of hand, foot and mouth disease (HFMD) dipped slightly to 1,117 last week, but this is still much higher than past years.

Weekly cases hit a four-year high from May 8 to 14 when there were 1,317 cases, The Straits Times had reported.

Another high was hit between May 22 and 28 with 1,349 cases, according to records on the Ministry of Health (MOH) website.

The number of cases has come down slightly in June. There were 1,234 between May 29 and June 4, and 1,117 cases from June 5 to 11.

Although slightly less than the figures reported in May, the latest figure is more than double the 540 cases in the same week last year, and much higher than the median number of cases in the last four years, which is 689.

The total number of cases for 2016 is now 20,587.

No childcare centre or kindergarten has been asked to close so far, said MOH. However, the Ministry has flagged three childcare centres on its HFMD watchlist.

These are centres that have more than 10 HFMD infections or where more than 13 per cent of the children enrolled have contracted the disease.

The three on the list now are Sasco Child Care Centre at Bukit Purmei Road, Amazing Star Montessori House in Ubi and Cambridge at Fernvale Road.

Parents of the centres on the list should look out for HFMD symptoms in their children, MOH said on its website.

Any child exhibiting HFMD symptoms should be kept away from school and crowded public places and be given medical attention early.
