Hong Kong health authorities have confirmed a local case of dengue fever, the third in a month.
Apple Daily is reporting that all three patients are from the Mid-Levels district.
Dengue fever is carried by the aedes mosquito and transmitted to humans by insect bite.
The Center for Health Protection (CHP) said the latest case is a 40-year-old domestic helper who lives with her employers in Panorama Towers on Conduit Road.
The woman has no recent travel history but she showed symptoms of fever, headache, muscle pain, vomiting and diarrhea on Aug. 27 before being admitted to Ruttonjee Hospital two days later.
Blood tests came back positive for the virus. She has since been discharged.
Others in the household have shown no symptoms, according to the report.
The maid had visited Graham Street Market almost daily through the Central-Mid-Levels escalators before falling ill.
She and the other two patients, both women aged 60 and 79, live close to each other, leading authorities to suspect the three cases might be related.
A CHP spokesman said it is investigating a possible connection.
He said people who have been to the vicinity of Conduit Road, the Central-Mid-Levels escalators, Shelley Street, Hong Kong Zoological and Botanical Gardens and Graham Street Market might have been exposed.
They should call 2125 2266 if they develop flu-like symptoms.
Dr. Ho Pak-leung, director of the Carol Yu Center for Infection in the University of Hong Kong, was quoted by Ming Pao Daily saying the three cases could be related.
A second outbreak has occurred since the Food and Environmental Hygiene Department took anti-mosquito actions last month.
Ho urged Mid-Levels residents to redouble efforts to drain stagnant water more often in order to stop mosquitoes from breeding.
