China is a hotspot for influenza types - many affecting humans. Influenza commonly infects birds and pigs as well and there they mix and emerge as new strains. These are common events and cause pandemics in humans.
Less frequently we think of influenza affecting other animals but China's Ministry of Agriculture reports of two tigers that recently died of H5N1. Just over 10 year's ago Thailand lost 150 tigers from influenza.
Get your shot! Not that you'll protect tigers but you may protect the people around you.
