Hadassah Commemorates World Malaria Day 2017 and Eradication of the Disease in Israel

2013 Malaria Conference in Jerusalem
Hadassah is very proud to have played a major role in the elimination of malaria in Israel decades ago. Israel remains malaria free today.

While malaria continues to kill hundreds of thousands of people around the globe, Israel, thanks to a collaboration between Hadassah and a pioneering microbiologist, eradicated the disease decades ago.

Dr. Israel J. Kligler, upon his immigration to Israel in 1920, created a multi-pronged approach to the malaria problem. It included draining the marshes that were a breeding ground for mosquitoes and their larvae; adding the Gambusia species of fish to the water, because they fed on the larvae of the mosquitoes he wanted to eliminate; spraying larva-infested areas; improving housing conditions; and mounting a vast community education initiative. 

Dr. Kligler first did his research under the auspices of Hadassah’s American Zionist Medical Unit, which later evolved into the Hadassah Medical Organization. He then served as Director of the Malaria Research Unit of Mandatory Palestine’s Department of Health, eventually becoming one of the first Professors of the Hebrew University, where he directed the Department of Hygiene and Bacteriology. The precursor of today’s World Health Organization called Dr. Kligler and his colleagues "benefactors not only to the Palestinian population but to the world as a whole.” Dr. Kligler’s story is preserved in his book, The Epidemiology and Control of Malaria in Palestine, published in 1930.

In the decades that followed Dr. Kligler’s work, the World Health Organization put a lot of money and effort into solving the malaria problem with mosquito netting and insecticides. As Maureen Malowany, a Hadassah-Hebrew University Braun School of Health and Community Medicine Public Health and Medicine Historian, explains: “When nets became the darling of the funders, countries no longer allocated funding for mainstream malaria control at the larval level.” This strategy faced reduced success, as resistant strains of malaria began proving a major obstacle to eradicating the disease. In any case, the netting and insecticides did not get to the source of the problem--the larvae of mosquitoes that are prevalent in countless pools of water. Some mosquito experts today feel that the strategy developed by Dr. Israel Kligler for killing mosquito larvae--introducing into the water sources the species of fish that feed on these larvae--should remain a part of the toolbox to eliminate malaria around the world. 

As Ms. Malowany notes, there could be “a phenomenal melding of 21st century technology with tools from an old toolbox.” Especially, as she brings out, since “despite billions invested in malaria vaccine research and mosquito netting, the problem persists and may even be getting worse.”

In sub-Saharan Africa, malaria causes the death of a child every 30 seconds. Some 250 million people worldwide are infected by the parasite.

In December 2013, specialists from around the world came to Jerusalem to attend a Conference entitled “Revisiting Malaria: Moving from Control to Sustainable Elimination,” presented by the Sanford F. Kuvin Center for the Study of Infectious and Tropical Diseases at the Hebrew University of Jerusalem and the Braun School. Ms. Malowany chaired that conference along with Bart Knols, Chair of the Advisory Board of the Dutch Malaria Foundation. The 2013 Conference recognized the contributions of Dr. Israel J. Kligler who, over 90 years ago, led the successful effort to eradicate what was then referred to as “the most important disease in Palestine.” 

As Dr. Kligler wrote in his book, in describing his early inroads toward malaria elimination: “Even in advance of the evidence of figures and charts, the attitude of the population had changed; they had come to realize that malaria was a preventable disease.”

Today, as global citizens, Hadassah-Hebrew University scientists continue to do research into malaria. For example, Prof. Ron Dzikowski and PhD Student Inbar Amit-Avraham have discovered the genetic mechanism by which a particular parasite evades the body’s immune response to cause the most dangerous type of human malaria. The study was published in the Proceedings of the National Academy of Sciences (PNAS). As Prof. Dzikowski explains: “Understanding the molecular mechanisms by which the parasite evades human immune attack could lead to the development of new drugs that disrupt this ability and would give the human immune system an opportunity to clear the infection and overcome the disease.”

 “We can be the generation that ends malaria--one of the oldest and deadliest diseases in human history,” emphasizes The Roll Back Malaria Partnership, the global platform for coordinated action against malaria. Hadassah, as it has for nearly a century, remains an active participant in bringing   World Malaria Day’s 2017 theme—“End Malaria For Good”--to fruition.
