Pigs and jiggers: could wild swine be spreading the awful foot burrowing flea?

OLYMPUS DIGITAL CAMERAI wanted to go and see what this jigger thing was really about so I had my guys rent a car and we drove into Mtsangatamu town. Mtsangatamu (I still can’t pronounce it properly) lies along the edge of the Shimba Hills Wildlife Reserve and, according to my data, is a hot spot for tungiasis, or infections from the so called “jigger flea.”

It is a beautiful area. Filled with tropical trees and overgrowth, the landscape looks almost uncontrollable, despite the soil being so sandy that not a drop of water stands anywhere. The air is blistering hot.

OLYMPUS DIGITAL CAMERAPeople don’t get out here much, though the packed buses that pass by every few minutes indicate that the area isn’t entirely isolated. We drop off some gas for one of our drivers, who has to slowly fill his tank, drop by drop, with the tiniest of plastic funnels. Some development project should provide proper plastic funnels to these guys.

For some reason, we drive into the bush along a foot path, until we find ourselves wedged between a number of small pine trees. “We have to walk now,” I am told while I wonder why we drove this far anyway. Walking would have been easier.

We exit the car, walk through what a patch of neatly arranged trees. A tiny tree farm. I never see this in Western, ever. Coming out, we walk into a compound laid out in a manner wholly uncharacteristic of Kenya. A two story building sporting an upstairs patio complete with a winding staircase to the top, the place looked like the type of patchwork architecture that you associate with off-gridders in the US rather than Kenyan peasants.

OLYMPUS DIGITAL CAMERA“The Mighty Paraffee: If in need call XXXXXXXXXXX”

The Mighty Paraffee turns out to be a kid of about 24, chilling out in the shade. He built this place himself, installed power, has a guest room and an upstairs shower and toilet. His room is decorated with reggae stars and pictures of the saints. Indian music is blaring out of the building. I’ve seen creative interiors from reggae fans in Kenya, but this is something else. This kid should be in architectural school. He even made sure to place the building under a giant tree to keep it cool.

I never figure out what the family does for money and no one can tell me, but the mother is exceedingly proud.

No jiggers here. We walk on. After about a kilometer, we find a poor family sitting outside their house. Children aren’t in school and no one speaks any English indicating that none of them go.

OLYMPUS DIGITAL CAMERAHassan (one or our workers) brings over a little girl and tells me to look at her feet. Fatuma is 10 years old and her feet are infested with jiggers. She says the don’t hurt much in the day, but they itch at night. Her brother apparently has them, too. Her mother and her aunt do not.

Everyone is barefoot and they all sleep in the same house. I’m wondering if there might be something about the skin which makes kids susceptible while adults are spared.

I notice a group of goats in a pen and start asking questions about animals.

OLYMPUS DIGITAL CAMERATungiasis is a zoonotic disease. It is passed from wildlife to domesticated animals to people who bring it into the household and infect their other family members. Or so it is though. Not many people have really explored the question sufficiently. Of course, this is why I’m here.

They have about 15 goats, a few chickens and I notice a young dog and a cat walking around. I ask if they ever notice whether the dog ever has jiggers. They say no.

“What kinds of wildlife do you see around here?” One of the kids was killed by an elephant last year. There are wild dogs and hyenas which come and try to get the goats. Wild pigs dig up the cassava at night.

OLYMPUS DIGITAL CAMERAPigs. That has to be it. A big mystery has been why there is such a tight relationship between distance to the park and jiggers infections. Wild pigs come out of the forest, raid the fields of the locals and get water from the river, and then recede back into the darkness before morning. 5km is approximately the distance that a pig could feasibly travel and return home in one night.

Pigs travel through and around the compound, dropping eggs, they mature and are probably picked up by dogs, but are most likely picked up by kids walking in the bush. They then bring them back home and pass them on to their family members.

Hassan associates jiggers with mango flowers, but I probe him further and find that the flowers coincide with the very dry season, which could explain why pigs are making the trek to the river and why they prefer the fields since both water and food are probably scarce in the forest.

I have to send a student out to investigate this further.

OLYMPUS DIGITAL CAMERAAn old man comes out. He looks nearly 90, but is mostly likely on 60 at most. He has arthritis in his back. He shows me his feet which are moderately infected, mostly only between the toes. He asks for medicine. I tell him I’ll send some along. He offers me some boiled cassava which I graciously take. My colleague refuses because there are no cashew nuts with it, but I suspect that he’s worried about getting sick. I become concerned.

We take some pictures and go.

On the way back, we run into an elderly lady. She’s sitting next to her husband, who is busy getting lit on homemade beer at 11 in the morning. She shows me her feet. The spaces around her feet are infested with jiggers. It must be horribly painful.

OLYMPUS DIGITAL CAMERAShe points out that she doesn’t have a whole lot of feeling in her left foot. I notice that her skin in this area is clear; the bone is visible through her skin. I ask what happened. She says that she got bitten by a snake 40 years ago. She was pregnant. I ask her if the baby was ok. “The baby is standing there!”

I consider making a joke about a snake baby, but think better of it. I’m just amazed that both of them survived. The wound was horrible looking.

Somehow, we manage to pull ourselves out of the trees and move on. There are some baboons removing mites from one another on the road on the way back, and I take some pictures. My colleague is about to pass out from the heat. I offer to drive.


I paid a bribe: part 2

Same thing. Wrong way down an unmarked one way. Cop at the end. After arguing with him for a bit, I threw 1000 schillings at him and just left.

Does the environment cause poverty?

SESKwaleAfrican countries are blessed with ample cropland and resources, but suffer from crippling and unforgivable levels of poverty, have some of the shortest lifespans on the planet and the highest rates of infant mortality in the world. Meanwhile, Japan, Korea, Sweden, Switzerland and Singapore are wholly the opposite, yet mostly lacking in everything that Africa has. Clearly, the picture is more complicated than merely having access to a natural resources.

However, within countries, the picture might be different. African countries are complex and diverse places. Poverty is often confined to the most unproductive regions, areas with poor soils, poor rainfalls or dangerous terrains.

I was just working with some socio-economic data from one of our field sites, and noticed some interesting patterns (note the map up top). In Kwale, a small area along the Coast, socio-economic levels vary widely, but neighbors tend to be like neighbors and patterns of socio-economic clustering emerge.

Note that the poorest of the poor are concentrated to an area in the middle, which I know to be extremely dry, difficult to get to, difficult to farm and generally tough to live in.

I tried to see if socio-economic status (as measured through a composite material wealth index a la Filmer and Pritchett but using multiple correspondence analysis rather than PCA) was related to any environmental variables that I might have data for.

I fit a generalized additive model using the continuous measure of of wealth from the MCA as an outcome. Knowing that very few things in nature or human societies are linear, I also applied smoothing to the predictors to relax these assumptions. The results can be seen in the plot at the bottom.

A few interesting things came out. While it is hard to tell much about the poorest of the poor, we can tell something about the most wealthy. The richest in this poor area, tend to live in areas with the richest vegetation (possibly representing water), a high altitude (low temperature), high relief (no standing water) and in locations distant from a wildlife reserve (far from annoying and dangerous wildlife).

I’m not sure the wildlife reserve is meaningful (unless the reserve was an area undesirable for human habitation to begin with), but the others might be and represent a trend seen in other Sub-Saharan contexts. Areas without malarious swamps and ample farm land tend to do the best. Central Province, one of the most developed areas of Kenya, would be an example.

But the question has to be, does a harsh environment doom people to poverty, or do people self shuffle into and compete for access to more favorable areas? Is environmentally determined poverty (or wealth) an accident of birth, or the result of competitive selection?

Alright, back to work. Oh wait, this is my work. Well….

New Publication (from me): “Insecticide-treated net use before and after mass distribution in a fishing community along Lake Victoria, Kenya: successes and unavoidable pitfalls”

mjThis was was years in the making but it is finally out in Malaria Journal and ready for the world’s perusal. Done.

Insecticide-treated net use before and after mass distribution in a fishing community along Lake Victoria, Kenya: successes and unavoidable pitfalls
Peter S Larson, Noboru Minakawa, Gabriel O Dida, Sammy M Njenga, Edward L Ionides and Mark L Wilson

Insecticide-treated nets (ITNs) have proven instrumental in the successful reduction of malaria incidence in holoendemic regions during the past decade. As distribution of ITNs throughout sub-Saharan Africa (SSA) is being scaled up, maintaining maximal levels of coverage will be necessary to sustain current gains. The effectiveness of mass distribution of ITNs, requires careful analysis of successes and failures if impacts are to be sustained over the long term.

Mass distribution of ITNs to a rural Kenyan community along Lake Victoria was performed in early 2011. Surveyors collected data on ITN use both before and one year following this distribution. At both times, household representatives were asked to provide a complete accounting of ITNs within the dwelling, the location of each net, and the ages and genders of each person who slept under that net the previous night. Other data on household material possessions, education levels and occupations were recorded. Information on malaria preventative factors such as ceiling nets and indoor residual spraying was noted. Basic information on malaria knowledge and health-seeking behaviours was also collected. Patterns of ITN use before and one year following net distribution were compared using spatial and multi-variable statistical methods. Associations of ITN use with various individual, household, demographic and malaria related factors were tested using logistic regression.

After infancy (<1 year), ITN use sharply declined until the late teenage years then began to rise again, plateauing at 30 years of age. Males were less likely to use ITNs than females. Prior to distribution, socio-economic factors such as parental education and occupation were associated with ITN use. Following distribution, ITN use was similar across social groups. Household factors such as availability of nets and sleeping arrangements still reduced consistent net use, however.

Comprehensive, direct-to-household, mass distribution of ITNs was effective in rapidly scaling up coverage, with use being maintained at a high level at least one year following the intervention. Free distribution of ITNs through direct-to-household distribution method can eliminate important constraints in determining consistent ITN use, thus enhancing the sustainability of effective intervention campaigns.

Can African Countries Learn from North Korea’s Handling of the International Media? – An interesting perspective. He argues that African leaderships, rather than seizing crises as opportunities to draw attention and approval for their countries from Western donors, might actually benefit from clamping down on international media coverage, which often exploits and distorts the story. I’m thinking that the Ebola panic might have been averted if the media hadn’t picked up on the most freakish elements of the story, and focused rather on the mundane issues of poor public health care delivery.

Colonialism and development in Africa – “Most of Africa spent two generations under colonial rule. This column argues that, contrary to some recent commentaries highlighting the benefits of colonialism, it is this intense experience that has significantly retarded economic development across the continent. Relative to any plausible counterfactual, Africa is poorer today than it would have been had colonialism not occurred.” The authors, however, note the different contexts of colonialization and remark that results are mixed, but in general, the countries that have done the best (i.e. those which didn’t experience slavery) would be doing significantly better.

Stop Making Intellectually Disingenuous Market Arguments – “Shall we blame Twitter, trolls or bloggers? I am unsure of the underlying reason. But as we have seen far too, financial discussions seem to entail people arguing at cross-purposes. Bull-bear debates devolve into winning the argument at any cost. Previously, we had a true competition of ideas in the marketplace. Now, we have discussions that range between disingenuous and useless. The hunt for the truth has been replaced by the search for bragging rights.” Well, Barry, I don’t think you should limit your observations to only those talking about markets. It’s endemic now.

An autopsy review of sudden unexpected natural deaths in a suburban Nigerian population - “Sudden unexpected natural deaths accounted for 13.4% of all medico-legal autopsies. The male to female ratio was 2.1:1, and the mean age was 43.1 years ± 19.5 SD. Cardiovascular (28.3%), respiratory (18.2%), and central nervous system (12.6%) disorders were the major groups of causes. About 64.4% of cardiovascular deaths were due to hypertensive heart disease. Bacterial pneumonia, intracerebral haemorrhage, and breast carcinoma accounted for 34.4%, 60.0%, and 52.6% of respiratory, central nervous system, and cancer-related deaths respectively. Only 16.9% of cases occurred while the patient was admitted to the hospital.” Twice as many men are dying as women, they are dying of heart disease and the average age of death is 43, give or take 20 years. Time to move our focus over to chronic outcomes in developing countries. They are staring into a tidal wave of disease that’s going to break their health systems.

I liked so many things I read today that, rather than clutter social media, I’ll make note of them right here:

“Falling” by William McPherson – By far, the most depressing thing I have read in a while. McPherson is a Pulitzer winning writer and former editor at the Washington Post who chose a life of curiosity and is now paying the ultimate price. It’s awful that the brightest people have to be punished for thoroughly embracing life. So many people I know are going to go this way, it is possible that I might, too.

In India, Growth Breeds Waste NYT – Documenting India’s mounting problem of what to do with its waste. Europe went through their urbanization pains centuries ago. Unfortunately, developing countries are rising to the challenge fast enough. The problem, of course, is that elites are sheltered from the problems of waste and weak and corrupt government structures disallow people from demanding that their countries clean up. International environmentalists need to focus less on screaming about corporate polluting (though it is important) and need to start making demands for more boring things, like managing waste on a local level.

Stop calling me ‘the Ebola nurse’ – Kaci Hickox – This lady was a hero. She never had ebola, but was still illegally interned for having it because a few Americans don’t understand science. Anybody who supported her detainment should just stop speaking to me now. It was shocking how readily Americans were willing to lock people up simply because they were scared and even more shocking where the calls for her “arrest” came from. I give up. People like Hickox put their money where their mouths are. She did what most humans wouldn’t do and she was vilified for it. Unforgivable.

Ngugi wa Thiong’o and the language of NGOs

I just finished reading “Decolonizing the Mind,” a short book from perhaps Kenya’s greatest living writer, Ngugi wa Thiong’o. Ngugi is an interesting figure. Born into a peasant Kikuyu family in the fabricated colonial village of Kamiriithu in Central Province, he managed to take advantage of new educational opportunities during the colonial period and attended Makere University in Uganda and eventually Leeds in the UK. He returned to Kenya and eventually became Chairman of University of Nairobi’s Literature Department.

Though highly critical of colonialism, having been in the heart of the worst of Kenya’s experience with it, he was even more critical of Kenya’s post-colonial trajectory. He started a political theater in his hometown and was eventually jailed under the dictator Daniel Arap Moi.

In “Decolonizing the Mind,” Thiongo seeks to dissociate Kenya’s literature from that of the colonialists. He seeks to create a new African literature, by and for Africans. He would eventually abandon writing in English, choosing instead to write works in his native Gikuyu. Despite Thiongo’s call for an African literature, his European pedigree can’t be denied. He is Brechtian in both rhetoric and action. Hs politics are wholly Marxist and it can even be noted that his medium itself (the novel) is decidedly un-African. Moreover, despite his clear hostility to Europe and the United States, it is interesting the he would be jailed by his own countrymen and then would receive asylum and employment from the US.

I found his ideas of language, however, quite interesting. The colonialists, like the Americans, worked to debase indigenous cultural practices to further an imperialist agenda. Locals were weakened through the apparent dominance of English as a language for communication and business, and the language itself was presented in such a way that social hierarchies were reinforced.

This phenomenon continues to this day. Children are taught from an early age, to greet white people on the street with a scripted “How are you?” “I’m fine, and you?” The formal distance between the stilted Kenyan English spoken in Palirament and the guttural Sheng spoken on the streets of Nairobi is hardly an accident. English the language of oppression, control and government exploitation, and Sheng the language of resistance.

Given my recent experiences at Governmental and NGO meetings, however, what strikes me is how language continues to be used as a tool of control, but hat this vocabulary has been internalized by Kenyans themselves. I grit my teeth now when I head the term “capacity building,” which basically implies that people lack the capacity to help themselves without the good graces of NGOs and governmental organizations. It implies that people are helpless without the assistance of formal authoritarian structures. This is, of course, untrue (though one has to allow for the possibility that people often do things that run counter to their long term self-interest).

People may argue that the term is innocuous, but in my experience “capacity building” is often used in place of “training.” To me, words matter, and where “capacity building” carries with it the implications that there is an inherent defect to be rectified, training implies that the capability exists, but the knowledge not yet there. To put this in perspective, I don’t think that anyone would call any of my academic degrees to have been an exercise in “capacity building.” I can’t help but think that white people are trained, while black people are “capacity built.”

Worse yet is “gender empowerment,” which implies that women weren’t sufficiently capable of managing their own affairs prior to the arrival of some dubious microloan project. Again, in my experience, women all of the world are sufficiently empowered. It’s the men who need to be de-powered. The term is condescending and fails to appropriately recognize the inherent capabilities of individuals while at the same time avoids challenging the paternalistic structures which created economic disparities reprehensible practices like FGM, the buying and selling of women and the inability for women to hold men accountable for violence. In essence, the term blames the victim.

Both “capacity building” and “gender empowerment” reinforce the weakness of the individual and offer that the poor of Africa’s only hope lie in international organizations and their own authoritarian though wholly inept governments. It’s worth noting that the strategy is very similar to that of Christianity, which requires followers to believe themselves powerless and to blame for whatever awful fate has befallen them.

Sadly, both of these terms have worked themselves so deeply into the consciousness of people in SSA, that questioning their validity is futile, which is exactly the nightmare that Thiong’o writes of in “Decolonizing the Mind”. Pointing out that “training” is a more appropriate term than “capacity building” to locals will be met with black stares.
