The cost of treating disease is vastly greater than the cost of controlling
or preventing disease. In a time of global recession, the disparity in health
outcomes between developed and developing countries will most likely
widen. The rapid expansion in trade, foreign investment and international
travel mean that infectious diseases can have adverse effects not only on
health but also on economic growth and security. Although aid from donor
countries helps to drive development, mutually supportive policies across
a wide range of issues – economic, social and environmental – are essential
for combating the spread of disease, maintaining a healthy workforce and
ultimately reducing poverty.
