In a study published earlier this week, researchers from the United States reported that malaria originated in chimpanzees. The scientists discovered that the parasite that causes malaria is closely related to a parasite found in chimps.  

The sting of a mosquito bite is something most people try to avoid.  But scientists in Europe have come up with an unusual method for delivering a vaccine to human beings.  In a recent study, live mosquitoes were used to deliver live malaria parasites through their bites!

Today, the upper part of the Zambezi river has pushed past the highest ever recorded water levels. It’s cutting off communities, destroying crops and washing out the networks of small dirt roads that were the only travel system through this remote part of Africa.

Health challenges are becoming more numerous as new infectious diseases such as SARS, West Nile virus, and avian flu emerge. In addition, the accumulation of chemical pollutants in the environment is starting to take a toll. While infectious diseases are fairly well understood, the health effects of many environmental pollutants are not yet known.

Among the leading infectious diseases, malaria claims more than 1 million lives each year, 89 percent of them in Africa. The number of people who suffer from it most of their lives is many times greater. Economist Jeffrey Sachs estimates that reduced worker productivity and other costs associated with malaria are cutting economic growth by a full percentage point in heavily affected countries.

Although diseases such as malaria and cholera exact a heavy toll, there is no recent precedent of a disease affecting as many people as the HIV epidemic does. To find anything similar to such a potentially devastating loss of life, we have to go back to the smallpox decimation of Native American communities in the sixteenth century or to the bubonic plague that took roughly a fourth of Europe’s population during the fourteenth century. HIV is an epidemic of epic proportions that, if not checked soon, could take more lives during this century than were claimed by all the wars of the last century.

A friend of mine’s daughter went to Africa.  She had to end her trip early, fly to the US, and be hospitalized for malaria. She was a lucky American child who could get medical care for this disease that affects 350–500 million people worldwide each year.  Her life was never threatened.

New research suggests a simple, natural solution can save the lives of children suffering from hypoglycemia caused by malaria:  a spoonful of sugar.

Those of us in cooler climes often forget that malaria is an epidemic in many parts of the world— according to the World Health Organization, 300-500 million cases are diagnosed each year. And while insecticides are helpful, mosquitoes quickly build a resistance to the treatment. Fortunately, a Kentucky engineer named Tom Kruer has come to save the day with a cheap, low-tech solution to the malaria problem.

A team of researchers in Costa Rica’s Alberto Manuel Brenes Reserve have been searching for plants that might help cure the mosquito-transmitted disease known as malaria. While not a common disease in Costa Rica, the country’s tropical rainforests have a wide diversity of plants that sometimes cannot be found elsewhere in the world– and some of these species might contain medicinal properties to help stop malaria and other diseases. An estimated 1-3 million people die each year from malaria.

On April 25, 2008, designated the first World Malaria Day, 3,000 children or more in sub-Saharan Africa, majority of them under the age of five years, will die from malaria, one of the deadliest preventable diseases on the planet, global health data indicate.

Malaria, the dreaded and life-threatening disease continues to kill between 1 million and 3 million people each year, many of them pregnant women in Africa.

A two-month long 2,500 kilometers (1,550 miles) expedition on the Zambezi, one of Africa’s longest rivers, that begun on 29 March 2008 led by two adventurers, Helge Bendl, a journalist, and Andy Leemann, a boating enthusiast, partnering with the Roll Back Malaria Partnership, covering six nations in southern Africa aims to put a spotlight on the plight of malaria-stricken communities on the continent which contributes 90 percent of the global annual death toll.

Forget the meteor that slammed into the earth, or massive volcanic eruptions that may have led to extinction of dinosaurs. Here’s a new theory: mosquitoes may have done the deed, or at least contributed to the wipe-out.
