The Centre for Health Protection has confirmed today three Enterovirus-71 infection cases involving a two-year-old girl and two boys aged four and seven, bringing the year's total to 92.

The girl came down with fever, cough, a runny nose, and a rash on her hands and knee on October 28 and has consulted private doctors. Her three-year-old brother was earlier confirmed an infected case, too.

The four-year-old lives in Yuen Long and developed fever, ulcers in his mouth and a rash over his hands and feet on November 3. He was admitted to Princess Margaret Hospital the next day and is stable. Four boys and a girl, aged four to five, at his day centre had similar hand-foot-mouth disease symptoms from October 28 to November 3.

Of them, a four-year-old boy was a confirmed EV-71 case earlier. This boy's seven-year-old brother was confirmed today to have been infected with EV71. He had ulcers in his mouth and a rash over his hands and feet on November 1, and sought medical treatment from a private doctor.

There is no hand-foot-mouth disease outbreak in his school.

The centre provided health advice to these schools and is monitoring the situation.
