"More than 2.5 billion people around the world are at risk of contracting dengue, and 50 to 100 million people get sick from it every year. Dengue is present in more than 100 countries, and dengue is on the rise in many parts of the world. In Jakarta I know two person who contracted Dengu in recent weeks.
Dengue thrives in both cities and rural areas of the tropics and subtropics and is caused by a virus that is transmitted by mosquitoes. The symptoms are similar to a severe flu, and can be quite painful. There is no cure and no vaccine. Fortunately, dengue rarely causes death, though severe complications, like dengue hemorrhagic fever, can be lethal." Via (Google Blog)
The Dengue Branch of the US Centers for Disease Prevention and Control (CDC) has created DengueMap to show recent reports of dengue around the world and regions where people are at risk to catch it.
This map may be used as a guide for the assessment of dengue risk throughout the world. The dark blue regions represent areas of ongoing transmission risk as defined by CDC based on data from Ministries of Health, WHO and other international health organizations, journals, and knowledgeable experts.
Be aware of the disease and fight it.
