From Hong Kong's CHP :
" The Centre for Health Protection (CHP) of the Department of Health is today (June 24) investigating two imported and related cases of dengue fever, and hence urged members of the public to take precautions against the disease while they travel, especially to areas where dengue fever is prevalent.
The patients are two women aged 40 and 43. They have developed fever, headache, myalgia and skin rash since June 17. They were admitted to a private hospital on June 22. They are currently in stable condition.
Their blood specimens tested positive for the dengue NS1 antigen.
Preliminary enquiries revealed that the two patients were travel collaterals who travelled to Bali, Indonesia, in mid-June. The other travel collateral is asymptomatic so far.
Investigations by the CHP are proceeding."
