URGENT APPEAL FOR PUBLIC HEALTH SUPPORT - by: wini According to official sources, currently we are week 5 of the epidemic in Sudan

We are witnessing with great concern a rapidly growing number of cases of acute watery diarrhea around the country, first reported in mid- August 2016 in Blue Nile State (ElRoseiris and ElDamazine cities).At the moment, cases are being reported from 7 States: Blue Nile, Sinnar,Kassala, River Nile, ElGezira and ElGadaref, as well as the State of Khartoum, where the capital city of Khartoum is. Sinnar and Blue Nile States currently host a number of refugees from South Sudan.With the recent floods from the rainy season, the abundance of stagnant water, human waste and active vectors in the environment, compounded with limited capacity of the health system in Sudan, we are noticing high morbidity and mortality among affected individuals. Hence, the situation can be characterized as grave.......please continue the rest of the report in the attached PDF

US-FDA bans many common antimicrobial soap ingredients - by: JKMakowka

Companies will no longer be able to market antibacterial washes with these ingredients because manufacturers did not demonstrate that the ingredients are both safe for long-term daily use and more effective than plain soap and water in preventing illness and the spread of certain infections.

This is for me a very welcome move, as those have become quite ubiquitous while probably doing more harm than good.

And supporting study here:

Results There was no significant difference (P > 0.05) in bactericidal activity between plain soap and antibacterial soap at either test temperature. However, antibacterial soap showed significantly greater bactericidal effects after 9 h. These results suggest that although triclosan-containing soap does have antibacterial activity, the effects are not apparent during the short time required for hand washing.

Conclusions Antibacterial soap containing triclosan (0.3%) was no more effective than plain soap at reducing bacterial contamination when used under ‘real-life’ conditions.

Edit: Sorry, forgot to choose the correct category about hand-washing. Can it be maybe moved by a moderator? Thanks!]]>

Webinar Announcement: “The Ebola Crisis and Innovative WASH Solutions” - by: BijanFHI360 September 28 at 10:00 am EDT.

In 2015, Sierra Leone, Liberia, and Guinea began to enter periods of Ebola-free recovery. We know that innovative water, sanitation, and hygiene (WASH) interventions, specifically handwashing behavior change programs, played a critical role in halting the crisis and promoting ongoing community health. Now, we must ask ourselves “What’s next?” How can we ensure that the lessons learned from this crisis are incorporated into how the WASH sector promotes sustained behavior change? Can the response to the Ebola crisis frame how the world responds other to infectious disease outbreaks?

Experts from the U.S. Centers for Disease Control and Prevention and Global Communities will share key takeaways on the impact of infection prevention and control programs, community-led total sanitation approaches, and WASH interventions in schools.

Join the Global Public-Private Partnership for Handwashing for this interactive webinar on to discuss these questions and more.

Who Delivers without Water? A Multi Country Analysis of Water and Sanitation in the Childbirth Environment - by: neilpw
Who Delivers without Water? A Multi Country Analysis of Water and Sanitation in the Childbirth Environment


Access to water and sanitation during childbirth is poor across low and middle-income countries. Even when women travel to health facilities for childbirth, they are not guaranteed access to basic WATSAN infrastructure. These indicators should be measured routinely in order to inform improvements.

Re: Human fecal and pathogen exposure pathways in rural Indian villages and the effect of increased latrine coverage - by: bowenarrow Ross]]> Health issues and connections with sanitation Sun, 26 Jun 2016 00:33:36 +0000 Re: Human fecal and pathogen exposure pathways in rural Indian villages and the effect of increased latrine coverage - by: JKMakowka
For example a tube-well can hardly be considered "improved" if Giardia is still found (this is a large protozoa that should be very effectively filtered by the soil, indicating that the tube-well did not have a functioning sanitary seal at the top to prevent surface water intrusion).

The latrine findings are also not that surprising if one looks at the overall coverage, with was only 10% vs 38%, meaning high levels of open-defecation even after the intervention and thus obviously no impact could be found (the summary is a bit misleading in that regard).
However later they mention that there is also evidence of an increase in contamination of ground water due to the pour-flush pit-latrines used, which again is a well known fact that these lead to higher groundwater contamination if installed in areas with high ground-water tables.

So while this study is certainly very interesting, the conclusions made are somewhat misleading as there seems to have been neither really improved tube-wells nor an appropriate sanitation technology used in the area.]]>

Human fecal and pathogen exposure pathways in rural Indian villages and the effect of increased latrine coverage - by: campbelldb Sanitation Updates

Human fecal and pathogen exposure pathways in rural Indian villages and the effect of increased latrine coverage. Water Research, Volume 100, 1 September 2016, Pages 232–244.

Authors: Mitsunori Odagiri, Alexander Schriewer, et al.


- Application of Bacteroidales MST to evaluate improved sanitation impacts
- Widespread human and animal fecal contamination detected in homes.
- Pathogens detected in drinking sources associated with subsequent child diarrhea.
- Public ponds used domestically were heavily contaminated with multiple pathogens.
- No decrease in human fecal or pathogen contamination from increased latrine coverage.

In conclusion, the study demonstrates that

(1) improved sanitation alone may be insufficient and further interventions needed in the domestic domain to reduce widespread human and animal fecal contamination observed in homes,
(2) pathogens detected in tubewells indicate these sources are microbiologically unsafe for drinking and were associated with child diarrhea,
(3) domestic use of ponds heavily contaminated with multiple pathogens presents an under-recognized health risk, and
(4) a 27 percentage point increase in improved sanitation access at village-level did not reduce detectable human fecal and pathogen contamination in this setting.]]>

Re: SaniPath - Assessment of Fecal Exposure Pathways in Low-Income Urban Settings (Emory University, USA) - and appeal to SuSanA members for input - by: karobb
Thanks so much for your message and apologies on the delay in getting back to you!
Thanks for bringing up the important point regarding wastewater irrigation and health. One of the key findings from the in-depth SaniPath study in Accra was that the dominant pathway of exposure to fecal contamination for young children was through the food supply. This has important implications for the WASH sector – that typically ignores food safety. As you point out, urban agriculture is a key contributor to the food supply in many cities, and wastewater irrigation is a common practice. Our study demonstrates that this pathway for exposure combines high frequency of exposure and high “doses” of fecal contamination – making it a high-risk pathway that should be a priority for intervention. We’ve recently submitted a manuscript by Wang et al. detailing this finding to the American Journal of Tropical Medicine and Hygiene and we can send you a copy once it’s published. We also conducted a sub-study lead by a PhD student at the London School of Hygiene and Tropical Medicine, Prince Antwi-Agyei. The results of that work can be found in a journal article entitled “A Farm to Fork Risk Assessment for the Use of Wastewater in Agriculture in Accra, Ghana” (

Regarding your question about applying SaniPath in rural or peri-urban areas, we’ve put some thought into this in the past but don’t currently have plans to develop a version of the tool for rural areas. However, we do have plans to apply the tool in peri-urban areas and smaller towns where sanitation investments are planned through a partnership with EAWAG.

We've also recently circulated a policy brief on public toilets based the SaniPath study in Accra, Ghana ( that may be of interest.

We really value you taking the time to contact us and for sharing your insights! Please do keep in touch!

Re: Link between poor sanitation and higher risk of Adverse Pregnancy Outcome - by: jbr
"While it is intuitive to expect that caste and poverty are associated with poor sanitation practice driving APOs, and we cannot rule out additional confounders, our results demonstrate that the association of poor sanitation practices (open defecation) with these outcomes is independent of poverty. Our results support the need to assess the mechanisms, both biological and behavioural, by which limited access to improved sanitation leads to APOs."

We feel that this study gives a fresh perspective on the link between WASH and Health. Tdh uses WASH to support maternal newborn and child health (MNCH) programming, focusing on girls and women of reproductive age. Although we try to influence delayed pregnancy, among the most significant factors in terms of readiness for motherhood are nutritional status, psycho-social well-being, level of education and status within the family. Since we monitor hundreds of girls and women in our protection/health programmes, this puts a new research angle on our radar.

For example, it would be interesting to explore the relationship between age, open defecation and adverse pregnancy outcome.]]>

Re: The elusive effect of water and sanitation on the global burden of disease - by: muench Thanks for telling us about this article (title: The Problem With Evidence-Based Policies) which explains nicely the problems with randomized controlled trials (RCTs)!

I bumped into this problem last year while working on the Wikipedia article on "mass deworming" ( You can see here on the talk page ( how we (in particular Joe Turner) were trying to make sense of new studies (Cochrane Review) that showed no evidence of school based deworming programs on child health, and struggeling to present everything correctly in the article. There were several factors involved but one was that RCTs were regarded by other Wikipedia editors as the "gold standard" of research and if it wasn't an RCT then it was deemed as irrelevant.

In this context, I want to point out to you the famous parachute paper which is pretty revealing and thought provoking (and funny!):
Parachute use to prevent death and major trauma related to gravitational challenge: systematic review of randomised controlled trials


P.S. the person who sent me this parachute paper also wrote the following per e-mail (he used to work for WHO but is now retired; he wants to stay anonymous):


I have checked the web page and have a comment regarding evidence on helminthiasis control. The papers you quote are systematic reviews of randomized controlled trials (RCT). Observational studies are, by the Cochrane group, not considered appropriate and are disregarded for decision making and their “golden standard” is that ONLY systematic reviews of RCT should allow for decision making for what works in health and also in public health (PH). Their patronizing message, that they include in most if not all their published papers, is: In modern medicine, the efficacy of an intervention should be investigated in well-designed randomized trials. Results from the trials should be collected in a high-quality systematic review, if possible with a meta-analysis. And finally, the evidence should have its repercussions on practice guidelines.

This in is a wrong starting point. It is wrong as many PH decision have been made by observational studies or simple “expert opinion”, have worked and continue to work for the benefit of millions of people around the world. Vaccination of small pox, “discovered” in 1798, is a typical example that has allowed us to achieve the only eradication yet of a disease. Similarly the evidence for the feasibility of the eradication of guinea worm has never been proved by any RCT. I could go and on with both examples in PH and general medicine. I am attaching a comic paper (parachutes) that was published time ago on the BMJ on parachutes……….the recommendation for the RCTs fundamentalist stands today as it did when it was published!

Regarding worm infections they just do not know what they are speaking about. The issue is due to the “over-dispersed distribution” of worms in infected populations and the difference between macro and micro parasites. As these macro parasites (worms) do not replicate (at least most of them and surely the one we are discussing) in the human final host it takes time to build a worm load and those people that have high worm loads (that are few in an infected population) are those that have the worse effects of worm infections, with associated stunting, malnutrition, anaemia in case of hookworms and schistosomes, etc. Those with few worms have more subtle pathology and morbidity.

As a consequence those that have a high worm load will benefit more from intervention and those that have a few worms will of course benefit less. You do not need a rocket scientist to understand that!!! In an RCT you need to take this into account and to take this into account you need huge sample sizes and compare effects in different groups based on their original worm load. So the design of the study must be based on the host parasite relationship and dynamic of transmission and ecology of the infections. Very few RCT on helminthiasis have done this as it would cost a fortune. Furthermore different parasites have different physio-pathological effects on their hosts. Hookworm will mainly cause anaemia (and this is directly related to the number of hookworms in the host and the species (Necator americanus or Anchilostoma duodenale with A.duodenale having a more important impact on anaemia per worm as they cause more blood loss). Ascaris lumbricoides more an effect on growth, etc.

I am afraid the various Cochrane reviews on helminths did not take into account studies conducted in areas with mainly one parasite transmitted and mixed effects of one species with that of another (stunting for hookworm, etc. when hookworms will have effect on anaemia etc.). They even quoted papers I was involved in areas of hookworm transmission looking at effects on growth! They just have no knowledge on the epidemiology of helminthic infections and reach conclusions based on such biased views as they do not look at papers and read them as parasitologists but as “systematic reviwers” with no biological knowledge.

Furthermore all the present discussion on the relevance of impact large scale chemotherapy against worm infection regards more “subtle” effects such as growth, school performance, work performance and even increased wages of people treated versus workers not treated. This impact is important but forgets another element: large scale interventions prevent also deaths and severe morbidity of a small but important proportion of the population. That is per se sufficient to justify large scale chemotherapy against helminthic infections that WHO defines Preventive Chemotherapy. We could say that similarly the proportion of people with paralytic polio is “small” and that this per se should justify spending a billion USD a year to eradicate this horrid disease. If not one scientist dares to, most appropriately, argue this general point of view why does a small group of “systematic reviewers inquisition fundamentalists” argue so much on large scale Preventive Chemotherapy? What are their real objectives?

In the 19th century, in one of the most elegant studies on Ancylostoma duodenale ever performed, Italian parasitologists observed (observational studies again I am afraid!!) that the Italian workers that were drilling the St Gottard tunnel in Switzerland were becoming anaemic. Coming from the south of Italy most of them were infected with hookworms and due to the conditions of work in the tunnel and complete lack of sanitation they became severely infected with hookworms transmitted in the tunnel itself, consequently becoming very anaemic and many of them eventually dying. In 1880, Edoardo Perroncito first noted the correlation between hookworms and anaemia among miners digging the St. Gottard tunnel in the Alps. They also correlated worm loads with severity of anaemia and Grassi was the first to mention that counting worms was critical to understand the relationship with morbidity. Grassi in 1878 had looked at the importance of the worm load 40 years after Dubini and stated in Italian “la diagnosi viene agevolata dallo studio delle uova…..con queste ricerche arriviamo ad affermare la presenza dell’elminto; ma siccome dal suo numero dipende il grado della malattia, cosi’ fa profitto anche lo stabilire la diagnosi quantitativa. La quale é possibile all’occhio esercitato in base ad un fatto da me ripetutamente certificato, e cioè che la quantità delle uova è direttamente proprozionale al numero degli elminti” (reported by Ivo de Carneri page 253, Parassitologia Generale e Umana 11ª Edizione, 1989). 137 years later do we still need to have proofs that hookworm infection has an impact on anaemia based on intensity of infection and to justify large scale chemotherapy with the safest drugs ever used in medicine like albendazole and mebendazole?

I think the Cochrane group has a mentality similar to that of the 15th century inquisition and is unable to think beyond dogmas: i.e. that if you do not go through a RCTs (and especially their own review, their own “holy inquisition” to get their imprimatur) you will not be allowed to become PH policy. This is deeply and dangerously wrong and the visibility given by the press has been dangerous. Anthelminthic treatment on a large scale is only one of the PH interventions they have reviewed and “dismissed” as not evidence base. Their influence is dangerous and we need to combat it for the benefits of millions of people. For the time being I will continue to be with the heretics, the Giordano Bruno’s of today, and continue to promote large scale preventive chemotherapy, up to the time the Liverpool fundamentalists will get me and try to burn me!
