The polio vaccination was discovered in 1952, announced to world in 1955. A global effort to eradicate polio, led by the World Health Organization, UNICEF, and The Rotary Foundation, began in 1988. Using today, December 9, 2013 as a starting point, how long would it take to eradicate malaria worldwide?
Acoustic Larvicide is a technique where mosquito larvae are killed by rupturing their internal air bladders with acoustic energy. Their air bladders are resonant and therefore susceptible to acoustic energy in the octave from 18 kilohertz to 30 kilohertz. When sound at these frequencies with sufficient energy is put in the water the mosquito larvae instantly die.
This company, New Mountain Innovations appears to be the leader of this idea. Larvasonic.com
From 8-12 December, a conference titled 'Revisiting Malaria: Moving from Control to Sustainable Elimination' will be organised at the Hebrew University-Hadassah, Jerusalem, Israel.
The meeting conincides with the Centennial commemoration of the activities undertaken by Prof. Israel Kligler (picture, 2nd row, left), who was instrumental in eliminating malaria from Palestine. Malaria that in many ways was similar in intensity and impact as malaria seen in many parts of Africa today.
The meeting will be held in the form of a workshop and lectures, looking at past historical successes in malaria elimination, reviewing our current focus, and looking forward to identify what will be needed to move from control to sustainable elimination.
Also, workshop participants will work on scenario's for malaria elimination in island settings and ecological islands. The aim is to assist managers of NMCPs in moving forward in their country towards malaria elimination.
Participants have been selected from a variety of backgrounds that are considered essential in the planning and execution of operational malaria programmes.
Outputs from the meeting will be reported here on MalariaWorld, including a declaration by the participants.
The meeting is generously supported by the following organisations:
A recent paper (Anti-Plasmodial Polyvalent Interactions in Artemisia annua L. Aqueous Extract - Possible Synergistic and Resistance Mechanisms J J Suberu et al., PLoS ONE, November 2013 8 |11) opens the way for new antimalarial therapies. It gives an answer to several questions which had not been addressed properly in the scientific literature. The paper studied the additive, synergistic or antagonistic effect of several constituants of Artemisia annua. It confirms clearly that the aqueous extract of Artemisia annua is 3x as potent as pure artemisinin.

Is this just the tip of iceberg?
On 6 November 2013, WHO/ PAHO honoured initiatives from three malaria-endemic countries with the ‘Malaria Champions of the Americas Awards’. The Malaria Champions of the Americas awards were given to Colombia (Colombia Malaria Project), the Dominican Republic (National Center for Control of Tropical Diseases), and Brazil (Secretariat of Health of the State of Acre). The Malaria Champions of the Americas was launched in 2008 to identify, celebrate and inspire excellence in efforts to fight the disease.
It is often asserted that there are two malaria vector interventions in widespread use: long-lasting insecticide treated bednets (LLIN) and indoor residual insecticide spraying (IRS). Are either of these vector interventions? I’ll argue that the answer is, “No!” What does this mean for the development of new methods?

MalariaWorld is looking for authors to write columns about malaria - in the broadest sense. What we all read in scientific articles on malaria is only the tip of the iceberg when it gets to the world of malaria. Our malaria world is shaped by funding agencies, meeting outcomes, opinionated individuals and politics, but also you.
MalariaWorld as of today has 8102 registered members. We continuously check the validity of your email address to make sure that we remain connected with you, so you and 8101 other subscribers receive the MalariaWorld newsletter every single week of the year. This November we celebrated our fourth year of providing services to you. This was also a time to once more review our progress, including the progress we are making with the MalariaWorld Journal. The journal is now in its 4th volume and it is maturing, but we identified some real difficulties, one of which I want to bring to your attention here: manuscript reviewing...
The plasmodium parasite needs cholesterol for survival and multiplication. The replicative capacity of plasmodium liver forms is remarkable, achieving the fastest growth rates known.
We are very excited to be connecting with you through MalariaWorld. The Malaria Eradication Scientific Alliance – MESA - will feature the ever growing evidence base in malaria elimination, from science, to lessons learned, and policy.

Dear Partners in Vector Control,
We are pleased to update you on the status of the newly-established Pan-African Mosquito Control Association. Comprised of vector control and research professionals from Africa and beyond, our membership base has been growing rapidly as we combine efforts towards an Africa free of mosquito-borne diseases.
We invite you to:
It is not very often that we see a talk exclusively on malaria at a global TED event. And now there is a new one. Anyone that has an interest in malaria by now should have heard about Sonia Shah. She wrote the excellent book 'The Fever' in 2010, a book that received praise around the world. Shah has now condensed the book in a 15 minute talk. She does so in a simple yet authorative manner that is clear even to someone that has never heard about malaria.
Basically she describes three reasons why it is so hard to tackle malaria in its heartland: Africa. First, the complexity of the disease and the challenges we continue to face to either combat the parasite or its vector make it a tough disease to conquer. True. Parasite resistance to drugs, vector resistance to insecticides, the difficulty of making a potent vaccine, it all adds up to what may seem an impossible task. Second, she talks about economics, the costs involved and the lack of the myriad of resources needed (health facilities, trained staff, control personnel and so on) to do a thorough job. Again true. And third she talks about indifference and the fact that malaria is as engrained in developing country nations as a simple cold or flu in the North. Hmmm, food for thought.
Artemisia ketone is the major constituent of essential oil of many artemisia plants, often up to 60 %. A lot of research work has been devoted to other constituents like artemisinin, scopoletine, limonene, eucalyptol, borneol, luteolin, eupatin, casticin, but artemisia ketone is completely absent in the scientific literature. The molecule had been discovered in Artemisia annua in 1938 ( WA Jacobs et al., Annual Review of Biochemistry 7,1-193) but then fell into oblivion.
I am a civil engineer with experience in drainage and flood control. Drainage and flood control infrastructure can be an important part of integrated pest management as a means for larval source management.
Unfortunately, the related drainage infrastructure for a diked area typically has a number of drawbacks: 1) during dry periods, the drainage system for the low-lying land protected by the dike will inevitably include areas of stagnant water; 2) the lowered water table will cause the land to subside - which will make gravity drainage more difficult and produce more stagnant water; and 3) wetland environments will be severely degraded, harming flora and fauna.
Diked areas adjacent to tidally-influence watercourses can use tidal water level variations to significantly reduce stagnant water in the drainage system; reduce subsidence; and enhance wetlands.

The film below was submitted to MalariaWorld by Dr. Pierre Lutgen.
On several occasions Patrick Ogwang from Uganda and Pierre Lutgen from Luxemburg have informed us on encouraging developments with herbal medicine in Africa, more particularly Artemisia annua. The film shows the program of the Makerere University sponsored by the Ministry of Health of Uganda.
Since my blog on MalariaWorld about Intellectual Ventures' invention to shoot down mosquitoes with laser beams, back in 2010, it has been very quiet. We have not seen any progress with this approach, but this week the TED talk by Nathan Myhrvold features in the Huffington Post (as part of their TEDWeekends section). I was invited to submit a blog in response to this renewed attention for this approach which I titled: Drones that combat malaria.
What do you think? Still a worthy goal or an idea that should be burried?
