Health
The occasional avian- or swine-flu outbreak notwithstanding, health conditions in the region
are good. Travellers have a low risk of contracting infectious diseases compared to much of
Asia. The health system is generally excellent. However, observe good personal and food
hygiene and take antimosquito measures to prevent infectious diseases. If your health insur-
ance doesn't cover you for medical expenses abroad, consider supplemental insurance.
Diseases
DENGUE FEVER
Dengue is a viral disease transmitted by mosquitoes, and there are occasional outbreaks in
Hong Kong. Unlike the malaria mosquito, the
Aedes aegypti
mosquito, which transmits the
dengue virus, is most active during the day, and is found mainly in urban areas, in and
around human dwellings. Signs and symptoms of dengue fever include a sudden onset of
high fever, headache, joint and muscle pains (hence its old name, 'breakbone fever') and
nausea and vomiting. A rash of small red spots sometimes appears three to four days after
the onset of fever.
You should seek medical attention as soon as possible if you think you may be infected. A
blood test can exclude malaria and indicate the possibility of dengue fever. There is no spe-
cific treatment for dengue. Aspirin should be avoided, as it increases the risk of haemor-
rhaging. The best prevention is to avoid mosquito bites at all times by covering up, and us-
ing insect repellents containing the compound DEET and mosquito nets.
GIARDIA
This is a parasite that often jumps on board when you have diarrhoea. It then causes a more
prolonged illness with intermittent diarrhoea or loose stools, bloating, fatigue and some
nausea. There may be a metallic taste in the mouth. Avoiding potentially contaminated
foods and always washing your hands can help prevent giardia.
HEPATITIS A
Hepatitis A is a virus common in Hong Kong and Macau, and is transmitted through con-
taminated water and shellfish.
