A 27-year-old Tsuen Wan woman travelled to Indonesia August 5 to 19 and developed symptoms on August 20. She attended Yan Chai Hospital's Accident & Emergency Department three days later and is now in stable condition. Her four home contacts have no symptoms.

The centre will issue letters to doctors informing them of the recent Dengue fever situation in the region and alert hospitals to maintain vigilance.
