Rabies, tetanus, leprosy, and malaria.

The developing world is still endemic to rabies, tetanus, leprosy, and malaria. Globally more than 55000 people die of rabies each year, about 95% in Asia and Africa. Annually, more than 10 million people, mostly in Asia, receive postexposure vaccination against the disease. World Health Organization estimated tetanus-related deaths at 163000 in 2004 worldwide. Globally, the annual detection of new cases of leprosy continues to decline and the global case detection declined by 3.54% during 2008 compared to 2007. Malaria is endemic in most countries, except the US, Canada, Europe, and Russia. Malaria accounts for 1.5-2.7 million deaths annually. Much of the disease burden related to these four infections is preventable.
