The Centre for Health Protection (CHP) of the Department of Health is investigating two confirmed cases of Enterovirus-71 (EV71) infection and urged the public to be vigilant against the disease.
A CHP spokesman said today (November 21) that the first case involved a 10-year-old boy who developed Hand, Foot, Mouth Disease (HFMD) symptoms, including fever, vesicles on palms and soles, and oral ulcers on November 1. He sought medical treatment from doctor and did not require hospitalization. He has recovered with symptoms subsided.
His stool specimen saved earlier this week yielded positive results to EV71.
CHP's investigation revealed that the boy had no travel history. Other family members are asymptomatic.
Eight other children in the residential institution he attended developed similar HFMD symptoms between October 19 and November 5. One of them, a three-year-old boy, was confirmed to have infected with EV71 earlier (press release was issued on November 5). There was no new case of HFMD after November 5.
The second case involved a 7-year-old boy who developed fever, vesicular rash over hands and knees on November 6. He consulted a private doctor the next day and was admitted to Princess Margaret Hospital on November 9. He was discharged on November 13.
CHP's investigation revealed that he had no travel history and his home contacts are asymptomatic.
A total of 97 EV71 infection cases have been reported to CHP so far this year. There were 35, eight, 16 and 12 cases in the years 2004, 2005, 2006 and 2007 respectively.
