Hong Kong is not at risk from malaria, according to the latest World Malaria Risk Chart from the International Association for Medical Assistance to Travellers.
In fact the disease, which is caused by the parasite Plasmodium transmitted through the bites of infected mosquitoes, has been under control in the city for more than 40 years.
Statistics from the Centre of Health Protection show that cases peaked at 2,000 in 1946; in 2009 there were 23 cases.
But Hongkongers shouldn't be complacent, particularly with our globe-trotting habits. Since the 1970s, most malaria cases have been imported - meaning vigilance needs to be maintained to keep the disease at bay.
Symptoms of malaria include intermittent fever, chills, sweating, headaches, tiredness, poor appetite and muscle pain.
In typical cases, the fever presents itself, subsides for one to three days and then returns in a cyclical pattern.
