Avian Influenza risk in Nanjing

Avian Influenza Prevention Guide for Nanjing

Risk Score: 59/100

What is Avian Influenza

Avian influenza is a viral infection that primarily affects birds but can spread to humans through direct or indirect contact with infected poultry or contaminated environments. Symptoms in humans range from mild flu-like illness to severe respiratory complications. While human-to-human transmission is rare, certain strains pose serious public health concerns.

Local Risk Factors in Nanjing

Nanjing's location along the East Asian-Australasian flyway means migratory birds regularly pass through the region, especially around Xuanwu Lake, the Yangtze River wetlands, and nearby agricultural areas. The city's numerous live poultry markets and backyard farming practices in surrounding Jiangsu province create environments where the virus can circulate. Seasonal peaks typically occur during colder months when migratory birds arrive and poultry farming activity increases.

Prevention Steps

1. Avoid live poultry markets. If you must visit, do not touch birds, their droppings, or surfaces in market areas. Wash hands thoroughly with soap afterward.

2. Cook poultry and eggs completely. Ensure internal temperatures reach 70°C or higher. Avoid runny eggs and undercooked chicken.

3. Report sick or dead birds immediately. Contact Nanjing agricultural authorities if you notice unusual bird deaths in parks, near waterways, or in residential areas. Do not handle them yourself.

4. Maintain respiratory hygiene. Wear a mask in crowded outdoor areas near wetlands or parks during migration season. Cover coughs and sneezes, and wash hands frequently.

5. Stay informed. Follow updates from Nanjing Municipal Health Commission during seasonal alerts. Vaccinations for seasonal flu do not protect against avian influenza but reduce co-infection risk.

If you develop fever, cough, or breathing difficulties after contact with birds, seek medical care promptly and mention your exposure history to healthcare providers.
