Bill and Melinda Gates to fight malaria in Africa using smelly socks Newscast Media AUSTIN, Texas — A Tanzanian doctor has developed an innovative trap that attracts and kills mosquitoes with the smell of dirty socks. Dr. Fredros Okumu and his scientific team at the Ifakara Health Institute in Tanzania have learned that smelly socks attract four times more mosquitoes than a human being. The Bill and Melinda Gates Foundation together with Grand Challenges Canada, are funding the project in order to fight malaria in Africa. Dutch scientist Dr. Bart Knols first discovered mosquitoes were attracted to foot odor by standing in a dark room naked and examining where he was bitten, said Dr. Fredros Okumu, the head of the research project at Tanzania’s Ifakara Health Institute. But over the following 15 years, researchers struggled to put the knowledge to use. Then Okumu discovered that the stinky smell — which he replicates using a careful blend of eight chemicals — attracts mosquitoes to a trap where they can be poisoned. The odor of human feet attracted four times as many mosquitoes as a human volunteer and the poison can kill up to 95 percent of mosquitoes, he said. Okumu received an initial grant of $100,000 to help his research two years ago. Now the project has been awarded an additional $775,000 by the Bill and Melinda Gates Foundation and Grand Challenges Canada to conduct more research on how the traps should be used and whether they can be produced affordably. The current traps are expensive prototypes but Okumu hopes to produce affordable traps that can be sold for between $4 and $27 each. He said they hoped to develop the devices so they would work at the ratio of 20 traps for every 1,000 people. The “Smelly Socks Project” is one of many innovative projects that Bill Gates and his foundation are funding to fight tropical diseases. Below are some innovative ideas that have been funded. To keep feeding their innovation engine with creative ideas, Bill Gates Foundation continues to seek new applicants – especially those from developing countries whose direct experience can guide and tailor solutions to be most suitable for those most in need. If you have a great idea for global health and development, check the GCE website for calls for proposals. Your idea may be just what we are looking for. Do you know someone who has a great idea?

Smrdljivim čarapama protiv malarije i komaraca Ekipa koju vodi dr. Fredros Okumu iz Zdravstvenog instituta Ifakara u Tanzaniji otkrila je da vonj nogu najbolje privlači insekte koji onda upadaju u smrtonosnu zamku Ekipa znanstvenika u Africi nada se da će smrad prljavih čarapa postati učinkovit način borbe protiv malarije koju prenose komarci, bolesti koja svake godine ubije 800.000 ljudi u svijetu, piše Hina. Ekipa koju vodi dr. Fredros Okumu iz Zdravstvenog instituta Ifakara u Tanzaniji otkrila je da vonj nogu najbolje privlači insekte koji onda upadaju u smrtonosnu zamku. Uz potporu Zaklade Bill i Melinda Gates, znanstvenici su izradili dva prototipa smrdljivih zamki. U obliku kutije zamke "sadrže prljave čarape ili sintetičke predmete koji šire tipičan neugodan vonj znoja" i privuku "četiri puta više komaraca nego čovjek". "Kada komarci uđu u zamku koja miriše na čovjeka, oni pokušavaju ubosti i posisati krv, no umjesto toga usmrćuje ih insekticid ili biološki agens", objasnio je dr. Okumu. Znanstvenik se nada za dvije godine postaviti zamke u većem broju sela u Tanzaniji i testirati učinak na zdravlje stanovnika zahvaljujući stipendiji od 775.000 dolara iz Zaklade Gates i kanadske nevladine udruge Grand Challenges. Prema Svjetskoj zdravstvenoj organizaciji (WHO), malarija je usmrtila 800.000 ljudi u 2009. godini, a gotovo 90 posto tih žrtava je u Africi, od čega su 92 posto djeca mlađa od pet godina. Osim malarije, komarci prenose i denga groznicu, virusnu infekciju koja svake godine pogađa 50 milijuna ljudi, zatim žutu groznicu, virus Zapadnog Nila i filarijozu.
