Via Public Health England: PHE issues advice for travellers returning from China. Excerpt:
While occasional human-to-human transmission cannot be ruled out the main route of transmission is by close contact with poultry or other birds that are suffering from avian flu. PHE urges people visiting China to minimise their exposure to live poultry, avoid visiting live bird and animal markets (including ‘wet’ markets) and poultry farms, and to practise good hand and personal hygiene.
If travellers experience flu like illness within 10 days of returning from China, it is important to mention their recent travel when presenting to their GP. PHE has produced clinical guidance for health professionals in England on the assessment and investigation of patients with severe flu-like illness who have recently returned from China.
