The Centre for Health Protection warns that hand, foot and mouth disease cases are on the rise. During the week ending April 29, the consultation rate at private clinics was 1.8 per 1,000 consultations, compared with 0.7 per 1,000 the week ending April 8.

Noting the disease occurs throughout the year and there is seasonal trend with more cases occurring between May and July, the centre said letters were sent to childcare centres, kindergartens and primary schools in March urging precautionary measures. Another letter with health advice will be issued.

To prevent the disease:

* maintain good circulation;

* wash hands before eating and after going to the toilet;

* never share personal items such as towels and eating utensils;

* clean and disinfect frequently-touched surfaces, furniture, and toilets regularly with diluted household bleach of 1:99 concentration (1 part bleach to 99 parts water);

* clean toys and places which are contaminated by secretions with diluted household bleach of 1:49 concentration (1 part bleach to 49 parts water);

* parents should seek medical advice if their children develop hand, foot and mouth disease symptoms; and,

* children with the illness should stay at home and avoid contact with other children.
