Hongkongers are ill prepared for aftermath of natural disaster
Emily Chan and Chi Shing Wong say Hongkongers are largely unaware of the health risks associated with natural disasters, and that needs to change
Super Typhoon Haiyan has left thousands dead, and hundreds of thousands in desperate need in the central Philippines. Hong Kong's brush with a typhoon came most recently in September: Usagi, with all its potential of becoming the city's strongest storm in 34 years, eventually made landfall in Guangdong. While Hong Kong was fortunate to escape a direct hit, Usagi left 29 dead in Guangdong, cut off electricity and water supplies for many households, and wreaked havoc on public transport and communications networks.
Usagi was the sixth tropical cyclone that necessitated a Hong Kong Observatory warning this year, and the second requiring the hoisting of the No 8 signal. With climate change looming large, Hong Kong will probably be struck by more and stronger typhoons in the future. There may be no way to prevent such natural disasters, but surely the damage can be minimised if both the government and the people are well prepared.
The government stresses the need to take adequate precautionary measures to reduce the direct impact of the storms, in terms of casualties and property loss. In the same vein, people usually take measures to secure their property and stock up on food supplies.
Yet, this is unlikely to be sufficient when Hong Kong is hit directly by a typhoon as strong as or stronger than Usagi. Besides weather chaos, typhoons also bring along less visible, but no less threatening, risks to people's health. Incessant, heavy rain, leading to blocked drains, is a sure recipe for increasing cases of intestinal infection as a result of contaminated water and food supplies; higher humidity levels will foster mould growth, which leads to higher incidences of chronic respiratory diseases; water pools left behind by storms serve as a hotbed for mosquito breeding and hence dengue fever; metal from destroyed structures can rust, increasing the risks of tetanus, while damaged wires may cause electric shocks.
