Health :: 10 million people a year are affected by zoonotic viruses spread by non-human hosts
An estimated 50 million people were affected by zoonotics diseases, including H5N1 (bird flu), SARS and Rabies, between 2000 and 2005 and up to 78,000 died. No effective vaccines exist for the most common diseases. And the Dengue virus, which caused about a third of the deaths is experiencing a global resurgence. Zoonotic diseases can become serious killers if they adapt to human to human transmission — HIV and Measles are two examples.
