“About 1/5th of all global deaths were a result of infectious diseases.” (WHO)

Developing countries are most affected. The rate of death from infectious diseases is almost 14 times higher in low income countries than in high income countries.

Diseases passed from wildlife to humans, are a growing threat to human health, and human pathogens originating from wildlife have increased substantially in recent years

Infectious diseases have had a large impact on demographic trends, altering the age structure of heavily affected countries.
