The Department of Health has confirmed another case of enterovirus-71 infection, bringing this year's total to five.

A 21-month-old boy developed a fever with rash over four limbs and mouth on May 7. He has since recovered and was not hospitalised.

There was one confirmed EV-71 case last year and five in 2002.

The department called on people to maintain personal hygiene to prevent enterovirus infections.

They should:

* wash hands with soap before eating and after going to the toilet and changing nappies;

* cover their mouth and nose when coughing and sneezing;

* maintain good ventilation;

* clean thoroughly toys or appliances contaminated by nasal or oral secretions;

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

* children suffering from the infection should stay home and avoid contacting others until the illness has passed.
