Avian Influenza risk in Shenzhen

Avian Influenza Prevention Guide for Shenzhen Residents Risk Score: 63/100 — Moderate to High What is Avian Influenza? Avian influenza (bird flu) is a viral infection caused primarily by influenza A viruses that naturally circulate among wild birds but can spread to domestic poultry and, in rare cases, to humans. In humans, it causes symptoms ranging from mild respiratory illness to severe pneumonia and can be life-threatening. Why Shenzhen Faces Elevated Risk Shenzhen's subtropical climate keeps the virus active year-round. Dense urban populations near live poultry markets create constant exposure opportunities. The city's role as a major transit hub means travelers regularly arrive from outbreak regions in Southeast Asia. Local wet markets selling live chickens and ducks maintain close human-bird contact. Seasonal migration patterns bring infected wild birds through the Pearl River Delta. Humidity and temperature favor viral survival on surfaces. Weekend market crowds increase transmission chances. Five Prevention Steps 1. Avoid live poultry markets. If you must visit, wear a fitted N95 mask and sanitize hands immediately after. Do not touch birds or surfaces in market areas. 2. Cook poultry thoroughly. Heat kills the virus at 70°C internally. Avoid runny eggs and undercooked duck dishes, which remain popular locally. When dining out, ask restaurants about sourcing and cooking temperatures. 3. Wash hands frequently with soap for 20 seconds, especially before eating and after public transit. Carry alcohol-based sanitizer for market visits or crowded areas. 4. Keep distance from wild birds in parks like Lianhuashan and coastal areas where migratory birds gather. Do not feed or handle sick or dead birds. Report dead birds to Shenzhen CDC immediately. 5. Monitor symptoms after exposure. Seek medical care within 48 hours if fever and breathing difficulty develop. Contact Shenzhen CDC hotline: 12320. Stay informed through Shenzhen Health Commission updates, particularly November through March when risk peaks.
