Where the real battle is won

May 23, 2012 - 03:23 -- Ricardo Ataide

May 9th, 2012

I fly out from Sao Paulo, a true concrete jungle, for my very first trip to the Amazonian Rainforest. As I fly over it I see miles and miles and miles of untouched rainforest crossed by natural waterfilled highways, some black as the night others the color of clay. Suddenly, the Amazon River. A true inland sea slowly heading east. Even more suddenly, a city with highrises, traffic, smog... it's Manaus. I quickly leave Manaus and the infantile shock of having to conciliate my childish image of the Amazon and the reality of today's situation and head to the city of Cruzeiro do Sul, in the State of Acre.

Amazing statements by leading malariologists

May 21, 2012 - 20:51 -- Bart G.J. Knols

Last week, publication of the WHO report on insecticide resistance did not go unnoticed. It was taken up by the journal Nature, and in a news article by Amy Maxmen some truly remarkable statements by some of the leading malaria researchers are to be found. I trust that these people saw the article and gave consent to its publication, so any quote in it must really have come from them. Be prepared...

How was malaria of 100 years ago eradicated in Palestine/Israel? And without vaccine?

How was malaria of 100 years ago eradicated in Palestine/Israel? And without vaccine?

The desperate state of the Holy Land 100 years ago may be appreciated upon reading the following:

"I have referred to the question of heat as one too often forgotten, but there are at the present time still great dangers in this semi-tropical region. Palestine suffers severely from that great scourge of the tropics - malaria .............

Winston Hide's courageous move

May 18, 2012 - 09:57 -- Bart G.J. Knols

This week, Harvard School of Public Health's Associate Professor Winston Hide made a courageous move: he resigned from being the associate editor of the journal Genomics (an Elsevier journal). Why? Because he could no longer accept the inability of scientists in developing countries to access full articles stuck behind paywalls thrown up by publishers. A bold and remarkable step. He published the rationale for making this decision this week in the Guardian.

Can we maintain effectiveness of the tools?

May 17, 2012 - 12:30 -- Bart G.J. Knols

This week WHO reiterated the fragility of the gains the world has made over the last decade through intense deployment of vector control in the fight against malaria. Reuters published an online article on the matter titled 'Insecticide resistance threatens malaria fight'. In it, WHO Director General, Margaret Chan, warns of the seriousness of the situation in Africa and India. Apparently, in ever more places the toolbox, filled with four classes of chemicals, is gradually emptying.

How Not To Control Malaria

May 11, 2012 - 11:28 -- Patrick Sawa
Tags: 

The cost of endemic malaria to Africa is overwhelming. Yet the effects of the disjointed, unfocused and mainly misdirected control efforts are visible and significant. We saw 216 Million case of malaria in 2011 and had 650000 deaths due to malaria in the same timeframe. When compared with almost 250 Million cases and 863000 deaths just a short three years earlier, the effect is clear. In spite of the plethora of effective tools available to us, the elimination of malaria will largely remain a pie in the sky.

How do these rare, rare mosquitoes survive? Notes from Pailin.

May 7, 2012 - 10:56 -- Derek Charlwood

Now as I see it a blog is sort of a diary.  So although I posted one the other day I would still like to share thoughts, bemusements, about the mosquitoes and malaria in Pailin, infamous for the fact that it was the last stronghold of the Khmer Rouge (Pol Pot died from malaria here) and the place where resistance to artemisenine originated.  More recently it should be infamous for the rate and degree of deforestation.  This has, however, probably unwittingly been an extremely effective anti-vector measure.  The vector in this neck of the woods is the forest dwelling Anopheles dirus. 

Do we need to think more about gonotrophic cycles in mosquitoes and the effect they might have on parasite transmission?

May 5, 2012 - 15:32 -- Derek Charlwood

There is apparently considerable discussion about early biting shifts in mosquitoes like An. arabiensis.  (Why this might be so I hope to describe below – but be warned in a recent submission a referee questioned the number of Charlwood references quoted – I had to reply well they are really the only ones I know, and no one reads them anymore so why not – a bit like insinuating an obscure word that no one has ever read before into a text! - so you might at least know what to expect if I write anymore of them. i.e.

WHO's interim position statement on larviciding for malaria control in Africa

April 30, 2012 - 16:05 -- Bart G.J. Knols

Last week, WHO published a statement regarding the potential of larviciding for malaria control in Africa. This followed the circulation of a draft version of the statement in August 2011. That draft was sent to a limited group of people (how many I don't know) for comments (including myself). I attach the official version to this editorial.

After reading this, is there any reason (other than lack of will to do so) why malaria has not now been eliminated from Africa?

April 17, 2012 - 18:23 -- Anton Alexander

90 years ago, Palestine was deemed by the British Mandate to be almost "hopeless from the malarial standpoint". Much of the area was uninhabitable.




"Malaria stands out as by far the most important disease in Palestine.
For centuries is has decimated the population and it is an effective

E-interview with Prof. Marcel Tanner (Switzerland, 1952)

April 4, 2012 - 20:48 -- Bart G.J. Knols

 

Professor Tanner is Chief Executive of the Swiss Tropical and Public Health Institute (Swiss TPH), based in Basel. He is an epidemiologist and chair of medical parasitology and epidemiology at the University of Basel. Besides this, he is engaged in numerous activities and initiatives that research and control communicable diseases, notably malaria. 

A mosquito flight in 3D

March 26, 2012 - 13:20 -- Fabrizio Grieco

Insects employ a variety of cues to find and identify resources. One of the most intriguing questions about insect behaviour is how chemical cues influence communication and orientation. When studying mosquitoes, research is directed at understanding how human-emitted odours influence orientation from a distance and landing on the host, and how repellents interfere with these behaviours. This has an immense value if we think of a way to prevent malaria mosquitoes from detecting human hosts.

GM mosquitoes: A perspective from Oxitec

March 22, 2012 - 15:18 -- Bart G.J. Knols

The editorial below was written by Camilla Beech, Regulatory Affairs Manager,  Oxitec Ltd, UK, partially as a response to a recent editorial by Guy Reeves, on regulatory aspects of GM mosquitoes.

 

Having spent over 10 years developing novel genetic approaches to control insect pests, we’re acutely aware of the importance of proceeding with caution, of doing so in a transparent and open manner, and of engaging in the most effective way possible with the diverse communities who have an interest in the development and use of these new technologies.

The rock or wave dilemma

March 11, 2012 - 16:54 -- Ricardo Ataide

I don't know about you, but this week my Facebook, email and news feeds have been flooded with the Kony2012 video and the many pro- and con- reactions to it. I myself have watched the video and, albeit feeling it was over simplistic and a bit Hollywoodesc, I felt that it was clever as a tool to make people more aware of child-soldiers, war-crimes and the people responsible.

WHO should measure the prevalence of malaria in Africa

March 8, 2012 - 19:56 -- Bart G.J. Knols

The article below was written by Dr. Bill Jobin and first posted as a comment under the most recent poll. I elevated it to a Guest editorial.

 

It is unfortunate that we have recently seen a great deal of confusion about the amount of malaria in Africa.  The confusion arises because most of the people making the estimates are not scientists but artists; computer artists.  It would be better if we relied on scientists.  Computer artists, using their own data and their own inspirations, get varying answers and generate conflicting maps and graphs.  But scientists, using standardized techniques and randomized sampling, get the same answers, no matter who is doing the work.  We urgently need accurate numbers on malaria...

An exercise in collective thinking

March 1, 2012 - 14:06 -- Ricardo Ataide

In recent years, in Brazil and in South-East Asia at least, there have been reported decreases of P. falciparum cases that have not been coupled to a similar decrease of P. vivax. This has led researchers to focus more and more on P. vivax and it has also led to the ‘sudden’ realization that we know very little about it. Although numerous studies have looked at P. falciparum interactions with a myriad of other pathogens, virtually nothing is known in the case of P. vivax. Curiously, very little is also known between the interactions of both species with each other.

PALESTINE'S MALARIA ERADICATION LESSON FROM 90 YEARS AGO.

March 1, 2012 - 08:12 -- Anton Alexander

The disappointment and criticism about malaria elimination in Africa is palpable. There is an impression that the campaign of malaria eradication in Africa is sometimes rudderless, with money being thrown uselessly or ineffectively at the problem. 

Tackling The Malaria “End Game”: Regional Needs And Challenges For Successful Malaria Elimination

February 29, 2012 - 21:15 -- Bart G.J. Knols

The article below was written by Prof. John Beier, Editor of Acta Tropica, about a special issue of the journal published in March 2012.

 

This special issue (SI) of Acta Tropica features 20 articles highlighting the activities and plans of 10 NIH/NIAID International Centers of Excellence for Malaria Research (ICEMR) located in 7 malaria endemic regions of the world. The SI informs readers about diverse and complex malaria issues, and will be of special interest for students, investigators, and policy-makers who need to understand and deal with current challenges for malaria elimination. 

Guest Editorial: Scientific standards and the release of genetically modified insects for vector control

February 28, 2012 - 21:11 -- Bart G.J. Knols

This guest editorial was written by Dr. Guy Reeves of the Max-Planck institute in Plön, Germany.

 
Field trials of genetically modified Aedes aegypti mosquitoes have already progressed to free releases in populated areas in a number of countries. A recent publication in PLoS NTD provides a critical summary of the events leading up to these trials and is aimed at non-specialist readers. While advocating the value of field testing transgenic techniques for suppressing disease vector populations, it highlights a number of troubling scientific precedents.
