Kligler, a Jewish Zionist in Palestine, initiated the first start anywhere in the world of a successful national malaria elimination campaign. It is little realised today that Palestine back then was drenched in malaria, rendering it uninhabitable in many areas, leaving it a country almost empty. Kligler recognised in his quest for malaria elimination firstly the need to demonstrate that malaria elimination was in fact possible. Secondly, he noted that the old colonial attitudes which then prevailed around the world towards subject populations also existed in Palestine. He realised that to be effective in educating anyone to assist with malaria elimination in such a colonial environment, that person would need to be educated, and such education had to be conducted with 'dignity and respect'. Such an attitude is something that was (and still is in many places) sadly missing within former colonies. Kligler knew the Zionist dream of a Jewish homeland in Palestine would in all probability be an impossibility unless malaria could be defeated there. He accordingly set out to initially demonstrate on a very small scale what could be achieved by way of malaria control. With dignity and respect, he engaged with all the inhabitants, both Arabs and Jews, sometimes even individually if necessary, to educate about the disease and to explain why his anti-malarial works were necessary, thereby enlisting the inhabitants effective assistance in these works. The result was enthusiastic co-operation by the inhabitants for over twenty years which was eventually rewarded with malaria elimination. Unfortunately, the example shown by Kligler is little known to the rest of the world today, and unless communities suffering from the disease learn from such examples, the task of malaria elimination elsewhere around the world will continue to be fraught with great difficulty, and more than likely to result in failure.</p>","PeriodicalId":74100,"journal":{"name":"MalariaWorld journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9242530/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40581253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a mature and famous hygienist, Koch had travelled the Old World, where malaria was endemic. His first studies took place in Tanganyika, German East Africa (now Tanzania) in 1898 and thereafter in Italy and the East Asian archipelago. As malaria in Germany did not offer a sufficiently endemic situation, he chose the Istrian island of Brioni (Kroatia) to eliminate malaria. Because virtually all of Koch's publications are in German, his achievements on malaria never settled in the common memory of tropical medicine. Around the turn of the century the race to elucidate the transmission pathway through mosquitoes took place and though he hardly yielded any honour of priority, his research certainly determined the speed by which British and Italian contenders made their ways. His exertion and interference led to the awarding of the 2^nd Nobel Prize in Medicine to Ronald Ross only, leaving Giovanni Battista Grassi to draw the blank.

{"title":"Did malaria elimination begin to lose its way in 1925? \"If you think education is expensive, try ignorance.\"","authors":"Anton Alexander","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>This paper begins with a brief examination of the first start made anywhere of a successful national malaria-elimination campaign. This start was made in 1922 in Palestine. The paper examines the essential education that was required to make the campaign so successful, thereby ensuring all inhabitants treated all aspects of the malaria-elimination as an absolute priority. Such priority led to the vital cooperation required for the necessary steps in the malaria-elimination method. But the paper also highlights a criticism of the campaign by the League of Nations in 1925 when the League sent its Malaria Commission to Palestine to investigate the campaign which it had heard about. The author tends to conclude that the education of all the inhabitants, of both Arabs and Jews, and which resulted in the inhabitants' very strong cooperation, was actually contrary to, or in conflict with, the natural inclination of the members of the Malaria Commission whose governments were mainly still, in 1925, colonial powers. The paper then moves on to present times and concludes the lack of success in malaria-elimination in many areas throughout the world is greatly due to the failure to provide that same personal education to the inhabitants that was provided in Palestine 100 years ago, principally because the governments in many malarious countries have not moved on from colonial times. The author's personal conclusion, impression and opinion is that there appears to be hardly any sense of priority for the various malaria-elimination campaigns being presently conducted around the world, and where involved governments are probably still retaining old colonial attitudes when dealing with their respective populations.</p>","PeriodicalId":74100,"journal":{"name":"MalariaWorld journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9838089/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10604651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of the surveyed households, 98.4% owned a long-lasting insecticide-treated bednet or hammock (LLIN/LLIHN).
