A 23-year-old cholera patient sneaked out of Princess Margaret Hospital on Thursday to see her three-year-old daughter. The woman left the hospital at about 11pm, prompting the Centre for Health Protection to alert police to help find her. The woman and her daughter were found at about 5am yesterday at a flat in Ma Tau Kok Road, To Kwa Wan. The centre was checking the child's health and whether the woman had contact with anyone else. The pair have been allowed to stay in an isolation ward.
