Zika Virus risk in Hong Kong
Prevention Guide
Zika Virus Prevention Guide for Hong Kong (Risk Score: 61/100) What is Zika Virus Zika is a mosquito-borne viral infection spread primarily by Aedes mosquitoes. Most adults experience mild symptoms including fever, rash, joint pain, and conjunctivitis. The greater concern involves pregnant women, as Zika can cause serious birth defects including microcephaly in developing fetuses. Local Risk Factors in Hong Kong Hong Kong faces elevated risk due to its subtropical climate supporting year-round Aedes mosquito breeding, high population density creating ideal transmission conditions, significant international travel connections with Zika-endemic regions, extensive construction sites providing stagnant water breeding sites, and dense urban green spaces maintaining mosquito populations. Actionable Prevention Steps 1. Eliminate standing water around your home weekly. Check flower pot saucers, blocked drains, and discarded containers where Aedes mosquitoes breed. 2. Use registered insect repellent containing DEET, picaridin, or IR3535 on exposed skin during daytime hours when these mosquitoes are most active. 3. Install or repair window screens and use air conditioning when possible. Sleep under mosquito nets if screens are unavailable. 4. Wear long-sleeved clothing and light-colored, loose-fitting attire that covers arms and legs during peak mosquito activity periods. 5. Pregnant women or those planning pregnancy should postpone travel to areas with active Zika transmission and consult their healthcare provider about testing if exposure is suspected. Seek immediate medical attention if you develop fever, rash, or joint pain after potential exposure. Report suspected cases to the Centre for Health Protection at 2125 1111.
