The Centre for Health Protection warned people to guard against enterovirus 71 (EV 71) after a nine-month-old was confirmed to have the disease. The girl was admitted to Queen Elizabeth Hospital on July 12 after developing a fever and rash. She was discharged on Sunday. Eight cases of EV 71 infections have been reported to the centre this year. EV-71 is a viral infection usually found among young children. It can cause hand, foot and mouth disease, which is transmitted by contact with discharge from the nose and throat of infected people.
