New publication: “Long-Term PM2.5 Exposure Is Associated with Symptoms of Acute Respiratory Infections among Children under Five Years of Age in Kenya, 2014”
In early December, I was asked to submit a paper to a special issue on “Air pollution and health in Africa and the African Diaspora” which is great! But the deadline was Dec 31st, which is absolutely crazy. I pulled an amazing team together and somehow we made the deadline and now, here we are…. published!
Here’s the “video abstract.”
Introduction: Short-term exposures to air pollutants such as particulate matter (PM) have been associated with increased risk for symptoms of acute respiratory infections (ARIs). Less well understood is how long-term exposures to fine PM (PM2.5 ) might increase risk of ARIs and their symptoms. This research uses georeferenced Demographic Health Survey (DHS) data from Kenya (2014) along with a remote sensing based raster of PM2.5 concentrations to test associations between PM2.5 exposure and ARI symptoms in children for up to 12 monthly lags. Methods: Predicted PM2.5 concentrations were extracted from raster of monthly averages for latitude/longitude locations of survey clusters. These data and other environmental and demographic data were used in a logistic regression model of ARI symptoms within a distributed lag nonlinear modeling framework (DLNM) to test lag associations of PM2.5 exposure with binary presence/absence of ARI symptoms in the previous two weeks. Results: Out of 7036 children under five for whom data were available, 46.8% reported ARI symptoms in the previous two weeks. Exposure to PM2.5 within the same month and as an average for the previous 12 months was 18.31 and 22.1 µg/m3, respectively, far in excess of guidelines set by the World Health Organization. One-year average PM2.5 exposure was higher for children who experienced ARI symptoms compared with children who did not (22.4 vs. 21.8 µg/m3, p < 0.0001.) Logistic regression models using the DLNM framework indicated that while PM exposure was not significantly associated with ARI symptoms for early lags, exposure to high concentrations of PM2.5 (90th percentile) was associated with elevated odds for ARI symptoms along a gradient of lag exposure time even when controlling for age, sex, types of cooking fuels, and precipitation. Conclusions: Long-term exposure to high concentrations of PM2.5 may increase risk for acute respiratory problems in small children. However, more work should be carried out to increase capacity to accurately measure air pollutants in emerging economies such as Kenya.
New publication: Environmental and Household-Based Spatial Risks for Tungiasis in an Endemic Area of Coastal Kenya
New publication! I started working on this cool project on tungiasis (jiggers) with colleagues in Kenya and Japan way back in 2014. Today, I am happy to say that after much ado our work has finally seen the light of day, thanks to Nagasaki PhD student (and soon to be Dr.) Ayako Hyuga. It appears today in the journal Tropical Medicine and Infectious Disease (MDPI).
Environmental and Household-Based Spatial Risks for Tungiasis in an Endemic Area of Coastal Kenya
“#Tungiasis is a #cutaneous #parasitosis caused by an embedded female sand flea. The distribution of cases can be spatially heterogeneous even in areas with similar risk profiles. This study assesses household and remotely sensed environmental factors that contribute to the geographic distribution of tungiasis cases in a rural area along the Southern Kenyan Coast. Data on household tungiasis case status, demographic and socioeconomic information, and geographic locations were recorded during regular survey activities of the Health and Demographic Surveillance System, mainly during 2011. Data were joined with other spatial data sources using latitude/longitude coordinates. Generalized additive models were used to predict and visualize spatial risks for tungiasis. The household-level prevalence of tungiasis was 3.4% (272/7925). There was a 1.1% (461/41,135) prevalence of infection among all participants. A significant spatial variability was observed in the unadjusted model (p-value < 0.001). The number of children per household, earthen floor, organic roof, elevation, aluminum content in the soil, and distance to the nearest animal reserve attenuated the odds ratios and partially explained the spatial variation of tungiasis. Spatial heterogeneity in tungiasis risk remained even after a factor adjustment. This suggests that there are possible unmeasured factors associated with the complex ecology of sand fleas that may contribute to the disease’s uneven distribution.” #environmental #kenya #NTD #NeglectedTropicalDisease #parasitology #globalhealth #publichealth
Are dogs associated with infections by a skin burrowing flea in Kenya? Masanobu Ono and I with Kensuke Goto, Satoshi Kaneko, mwatasa Changoma just published a paper on #tungiasis in the journal Tropical Medicine and Health.
Most people haven’t heard of tungiasis, an ectopic skin disease caused by the skin burrowing parasite, T. pentrans. It causes itching, pain, is associated with serious secondary bacterial infections, gangrene, social exclusion and debilitation. It primarily afflicts the very young and very old and is found almost exclusively in the poorest parts of the poorest parts of the world. It fits the classic definition of a neglected tropical disease.
We explored associations of wildlife and domesticated animals with household level tungiasis in Kenya using a two stage complex sampling based survey in an area adjacent to a wildlife preserve.
Tungiasis is a ectopic skin disease caused by some species of fleas in the Tunga genus, most notably T. penetrans. The disease afflicts poor and marginalized communities in developing countries. Transmission of tungiasis comprises a complex web of factors including domesticated animals and wildlife. This research explores animal and environmental risk factors for tungiasis in an area adjacent to a wildlife reserve in Kwale, Kenya.
A two-stage complex sampling strategy was used. Households were selected from three areas in and around Kwale Town, Kenya, an area close to the Kenyan Coast. Households were listed as positive if at least one member had tungiasis. Each household was administered a questionnaire regarding tungiasis behaviors, domesticated animal assets, and wild animal species that frequent the peridomiciliary area. Associations of household tungiasis were tests with household and environmental variables using regression methods.
The study included 319 households. Of these, 41 (12.85%) were found to have at least one person who had signs of tungiasis. There were 295 (92.48%) households that possessed at least one species of domesticated animal. It was reported that wildlife regularly come into the vicinity of the home 90.59% of households. Presence of dogs around the home (OR 3.85; 95% CI 1.84; 8.11) and proximity to the park were associated with increased risk for tungiasis infestation in humans in a multivariate regression model.
Human tungiasis is a complex disease associated with domesticated and wild animals. Canines in particular appear to be important determinants of household level risk.
There really isn’t much out there. I found 15 papers on PubMed and Web of Science. I am looking for more.
(Davidson, 1970; Erulu, Okumu, Ochola, & Gikunju, 2018)
I found two case reports. The first was from 1970 documenting a case of a white woman being bitten in Voi when a black-necked spitting cobra (Naja nigricollis) entered her bed at night. She received prompt care of polyvalent antivenom, travelled to Mombasa the next day, received treatment again and was relatively mobile within a week. It too three months for a hole in her foot to finally heal and for normal sensation to return to her toes.
The second documented a bite from a black mamba (Dendroaspis polylepis) in Watamu. A 13-year-old boy presented to Watamu Hospital with labored breathing, frothing at the mouth, severe ptosis, pupils non-responsive with unreadable blood pressure and elevated heat rate. He was administered the SAVP polyvalent antivenom and the boy recovered.
Hospital based surveillance and clinician surveys
(Coombs et al., 1997; Ochola, Okumu, Muchemi, Mbaria, & Gikunju, 2018; M. Okumu et al., 2018; M. O. Okumu et al., 2019; Ooms et al., 2020)
Coombs, et al gathered data from four areas of Kenya using Ministry of Health records. It was found that bite cases varied by region. Documented deaths are rare. The incidence rate of snakebites varied by region, with Kakamega being low and areas like Samburu and Baringo being high. Documentation of snake bites was often incomplete. Many bites were recorded as “Other” in hospital records. Though environmental factors and habitats account for some variation in bite incidence rates, a lack of coordination of health facilities and inconsistent record keeping might also be a factor. Authors conclude that surveillance capacity needs to improve and that community should be educated to identify bites and provide appropriate treatment (i.e. only using tourniquets for neurotoxic bites from snakes like mambas.) Transport and proximity are noted as barriers to treatment.
Ochola, et al. Study on snakebites from four hospitals including Kakamega Provincial, Makueni District and two others. Two year retrospective study of hospital records form 2007-2009. 176 total bites, 91 in 2009. Bites peaked at 1-15 years of age, 132/176 bites occurred on the lower extremities. 49/176 were given antivenom. Most bites occurred in the dry season, in the bush and in the evening. Mortality was 2.27%. Authors found that antivenom was often not available, and use was inconsistent. Patients presented to hospitals 2 to 6 hours after the bite, mostly due to travel distance. 75% if clinicians believe that patients saw traditional healers before arriving at the hospital. Manual laborers at highest risk.
Ooms et al. study of health care workers in three countries including Kenya. HCWs reported that there was no gender disparity in snakebite victims, that most victims are between 21 and 30 and that most people are bitten when conducting farm related activities or walking. Only 12% of HCWs received training in snakebite management. Only 20% claimed that medicines were available. Snakebite incidence occurred in both urban and rural areas of all countries. Half of all respondents claimed that people seek traditional treatments before coming to formal facilities.
Okumu et al Paper on general poisonings. Snakebites are only one part of the paper but make up 33% of all cases that appeared at Jaramogi Oginga Odinga Teaching and Referral Hospital. Antivenom used in 58% of all snakebite case. “Black snakes” accounted for 37% of bites. Victims were not able to identify snake species in 38.6% of bites.
Okumu, 2019 Paper on cost of snakebite treatment. 127 snakebite victims attending JOOOTRH between January 2011 and Dec 2016. Most victims were 13024 years of age, 64 were female, 94 were from rural areas, 92 were bitten on the lower limbs. 49 bitten at night, 43 attempted to self-treat, median time to the hospital was 4.5 hours. Outcomes included cellulitis, compartment syndrome, gangrenous foot, psychiatric disorder and death. 1-5 days in the hospital. Median cost $26. Authors call for public health programs to educate the public on how to identify and treat snakebites.
(Snow et al., 1994)
Retrospective study of 4,712 households. Most bites were not from venomous snakes. Most people identified both venomous and non-venomous snakes as being potentially venomous. 68% of people sought treatment from traditional healers. Authors suggest that traditional healers be integrated int primary health care and hospital-based systems. Household heads were approached and administered a questionnaire in Kilifi and ask to retrospectively report bites. Out of 4,712 visits there were 121 case of snake bite reported, 57% were male. Most were Giriama. 55% were bitten at night. A73% on the foot. 94% bitten outdoors. Only 39% could reliably describe the snake. No deaths were recorded. 79% performed some kind of first aid immediately after the bite. 88% sought treatment, with 78% visiting the healer. Only 29% visited a hospital. There was evidence to suggest clustering of bites.

New chapter from myself in a Springer volume: “Access to Health Care in Sub-Saharan Africa: Challenges in a Changing Health Landscape in a Context of Development”
I wrote a chapter for “Health in Ecological Perspectives in the Anthropocene” edited by Watanabe Toru and Watanabe Chiho. I have no idea if they are related. Either way, my chapter “Access to Health Care in Sub-Saharan Africa: Challenges in a Changing Health Landscape in a Context of Development” occupies pages 95-106 in the volume.
Check it out, you can buy the book through Amazon for a cool $109, or just my chapter through the Springer site for $29 or you can simply write me and I’ll give you a synopsis.
Here’s the abstract for the book:
This book focuses on the emerging health issues due to climate change, particularly emphasizing the situation in developing countries. Thanks to recent development in the areas of remote sensing, GIS technology, and downscale modeling of climate, it has now become possible to depict and predict the relationship between environmental factors and health-related event data with a meaningful spatial and temporal scale. The chapters address new aspects of environment-health relationship relevant to this smaller scale analyses, including how considering people’s mobility changes the exposure profile to certain environmental factors, how considering behavioral characteristics is important in predicting diarrhea risks after urban flood, and how small-scale land use patterns will affect the risk of infection by certain parasites, and subtle topography of the land profile. Through the combination of reviews and case studies, the reader would be able to learn how the issues of health and climate/social changes can be addressed using available technology and datasets.
The post-2015 UN agenda has just put forward, and tremendous efforts have been started to develop and establish appropriate indicators to achieve the SDG goals. This book will also serve as a useful guide for creating such an indicator associated with health and planning, in line with the Ecohealth concept, the major tone of this book. With the increasing and pressing needs for adaptation to climate change, as well as societal change, this would be a very timely publication in this trans-disciplinary field.
Humans have had to deal with the threat of snakebites as long as humans have existed. While deaths from snakebites are rare, the outcomes are so severe and the nature of the animal so mysterious, that humans have developed all sorts of ways of dealing with them.
Witchdoctors, or Mganga as they are known in East Africa, are the first line for snakebite treatment here. The Waganga are fairly useless for treating many serious health issues, but they have carved out a niche for themselves for a few public health problems.
Our survey in Western Kenya confirms that nearly 100% of people who have been bitten by a snake visit the Mganga, regardless of whether they visit a formal health facility or not.
I went and sat down with an established Mganga here in Kwale and he was gracious enough to answer all of my questions openly and (mostly) honestly.
Hello, thank you for taking the time to speak with me today. Is English OK?
No, my English is not very good. Can we do this through a translator?
Of course. So, what happens when a patient comes in for treatment for a snakebite?
When the patient comes in, I first apply the “njiwe na njoka” (lit: snake stone). The stone sucks all the poison out of the wound. When you put it on the bite, it will stick. When the stone has absorbed all the poison, it will fall off.
What do you mean? Like it just sticks to the flesh without tying it?
Yes, if there is poison, the stone will stick to the body. When all the poison is gone, the stone will fall off. After it is done, I take the stone and wash it with milk several times and then use it again for the next patient.
What is the snake stone? Is it like a rock? I’ve seen people use charcoal in the villages. They tie it to the wound, it doesn’t appear to stick on its own.
No, this is different. This is a stone from the snake. The stone is in the skull of the snake, like that of a fish.
(Note: I did not know this, but some species of snakes have otoliths, like most fish. Snakes (and fish) are deaf in the traditional sense. The otolith is a piece of calcium which grows as the animal ages and sit on top of a bed of nerves. When there are vibrations, the otolith vibrates, stimulating the nerve bed so that the animal can “hear” motion around it. Not all snakes have otoliths but some species of burrowing snakes do.)
Where do you get the stone? Can you just buy it in the market?
The snake stones come from the Maasai, from big snakes in Maasai land. My teacher travels to Maasai land to get them and brings them back.
If the wound is fresh, I apply the stone. However, if it has been two or three days since the bite, I can’t use the stone anymore. Then I have to use a special medicine made from herbs and crushed snake heads. I mix it all together, then crush it into a powder and keep in a gourd.
When the patient comes in, I use a new razor blade to make small scratches on the wound. Then I rub the powder in it and bandage the wound. The wound will try to heal over time, so you have to make the scratches to be able to apply the powder.
Do you use the razor blade again?
No, I always use a new blade. (He was emphatic on this point.)
What is the powder made from?
Snakeheads. When we kill a snake, we keep the heads to make the powder. We mix it with roots, bark and leaves from special plants from deep in the forest. My teacher is a security guard in one of the forests and can get them when he can find them.
Wait, so your teacher is a forest ranger? Can’t he get by being an Mganga?
Yes. He is a forest ranger.
So he took the job so that he can get the plants from the forest whenever he needs them.
OK, so how many bites do you see per month?
It depends, some months I get more than others but mostly one every three months or so.
Do you refer them to the health facility for formal treatment?
Yes, I do. I treat them, then they go to the facility, then they come back to me. (I’m suspicious on this point, though the Mganga in question appears more together than most.)
Is there a religious component to this?
Well, there are two kinds of bites, those where the snake just bites and there is no witchcraft and those where someone has used magic to send the snake to bite you.
How do you know the difference?
If the bite heals quickly, there is no witchcraft. But if the bite is treated and does not improve then there is definitely witchcraft involved. At that time, I have to use powerful magic to get rid of the curse.
What do you do?
I send the snake back to the person who applied the curse. When we hear that someone nearby has been bitten, we know who applied the curse.
(Note: this is not uncommon. Witchcraft is often associated with hatred and revenge but the person applying the curse risks becoming cursed themselves. It is possible that snakebites are seen as a never ending battle of malevolent spiritual forces. What this does is sow distrust among people, even families and the Mganga is seen as the only cure. The result is that the Mganga are never without work.)
How did you learn this craft?
I was sick for a long time with stomach and head problems. I went to the hospital and it never got better so then I went to an Mganga. I improved. The Mganga suggested that I become on and I started training under him.
Thank you very much for your time.
I made this trip out to the coast, first to do some damn work and second because I can get out of Nairobi and be spared spending Nairobi money for a while. A week’s worth of not-Nairobi-money is money in the bank. In Nairobi, you simply walk outside and 1000 schilling notes start flying away.
Some things I noticed (I’ll get to the snakes in a minute):
- It’s damn hot out here. Nairobi is cold. Here, it’s like being immersed in a sauna continuously, except for the hours of 3 to 5 am, which become cold for some reason.
- Fish from the sea is good. There are ample stocks of mackerel out here. I always want to make 塩サバ and have a side of okra. Or ゴーヤ. Or 山芋. Or something.
- Somalis are cool dudes. As in, they want to do business, they want to make sure you are happy and that you come back again. Kenyan business people are really just interested in getting your money right then probably because they might be out of business tomorrow. They don’t care if you come back. But then, if you don’t keep customers, you will go out of business. Welcome to the world of business in Kenya.
- Somalis make somali coffee, as in, not Nescafe. They put coffee grounds in hot water and steam the shit out of it. It’s refreshing. Though I noticed that they were pulling water from a plastic jerry can on the floor. One has to wonder where the water comes from.
- As much as possible, avoid the tomatoes and onions they put on the pilau (a dish like 混ぜご飯.) Yesterday, as I was eating my pilau, I ate the tomatoes and onions. I knew that things would turn out badly. Imodium is my friend right now.
- Mombasa is a weird place. I always expect to see people with dancing monkeys or snake charmers on the street, but then you look closer and it really is Kenya. They really tried to make a nice city at one point, but the city services never caught up. Trash is a constant problem. But there’s this weird mix of Arab, Brit and Indian architecture. It truly is an international city. They also like perfume. And they love ice cream. I think because they don’t drink and smoke, they can actually smell and taste things.
- Tarbousch: I always used to get the Biryani there, but the waiter convinced me to try the chicken schwarma. Perhaps the best shwarma I’ve ever had. I ordered two in the end.
- Police: Are stupid. Like really dumb. My tuk tuk driver failed to stop for the police, likely because he couldn’t here them over the cacophony of tuktuk motors everywhere. I apologized to the policemen to be friendly. He tried to arrest me for the tuk tuk driver’s failure to stop. The policeman was obviously a complete moron. I had to start fake calling the Kenyan Ministry of Health to “report him.” Eventually he let me go. I hate those guys. Likely, he wanted money.
- Mombasa is remarkably music free. Given Somalia’s rich musical history and the ubiquity of Taraab music in Zanzibar, you would assume the Mombasa might have some kind of musical culture, but it does not. Plenty of people seem to buy stereos and the matatus blast out Bongo (TZ) music, but there’s a stunning lack of performance culture of any kind here. Again, I blame Moi.
- Living in Nairobi will make you really mean. You just stop being nice to people you don’t know. It’s a cancer really.
We just spent the day driving around Kwale looking for snakes, and/or people who had been bitten by snakes. As the last post showed, snakebites are a persistent problem along the Kenyan Coast, with more then 5% of the households we survey indicating that at least one person in the household had been bitten in the past two years.
It wasn’t difficult to find them.
Snakes are universally feared all over Africa and the associations with witchcraft make it a common topic of discussion. Everyone knows someone who has been bitten. They often know all the details, including where it happened and what occurred following the bite. It’s never a happy story.
We went deep into Kinango, an extremely rural area west of Kwale Town and found a friendly lady who seemed to know everything about everyone. She was incredibly jolly, pulled out some plastic chairs for us to sit under and cracked jokes the whole time. I even got to copy her collection of Sangeya music which she had recorded on her phone (another post but you can hear some of it here) at some local music festivals. In total I got more than five hours of live Sengeya and Chilewa music. In the music world, these would be called “field recordings.” Here, this is just music she cooks and cleans to.
Switching back and forth between snakes and Sengenya (in Africa it seems to be possible to have multiple conversations at once), she told us about a kid who had been bitten two days previous. She even told us where to find her, so off we went.
The child was collecting firewood around a mango tree near her home, when she was suddenly bitten by a large green snake, not once but three times on the foot. The snake bit once skated away, decided it wasn’t enough and came back and bit her twice more.
Ants had moved into the dead tree and hollowed out the area underneath. Presumably, the snake moved in previously and came out to warm up during the day.
The mother thankfully took the child immediately to Kinango Hospital and treated was administered. The child was given a three day course of antivenom injections and charcoal was wrapped around the wounds to absorb any venomous discharge. Though the child complains of some numbness in the area, it looks as if there won’t be any permanent damage. Thankfully.
We were also told of an old woman who had been bitten more than 20 years ago, and was badly scarred, figured out where she was and off we went again.
As we pulled up a friendly young lady came out to greet us, and showed us the way to the house out back. In the distance, we could see an old lady walking with a limp. Otherwise, she was completely fit and seemed to be cutting her own firewood with a panga.
She brought us out some chairs and sat down to chat. In 1992, she had been out back collecting firewood (a pattern) and was bitten on the foot by puff adder, one of the deadliest snakes in the world. She was bitten on the foot, and became immobile for nearly a week. A series of witch doctors were brought in, who administered charcoal rubbed into small cuts in the skin.
Necrosis set in, and watery blood erupted out of the wound site. A large number of maggots appeared. Finally, someone had the good sense to take her to the hospital, where she spent an entire year.
The details were unclear, but it appeared that the gangrene was so severe that multiple infections were presents. They likely had her on intravenous antibiotics for an extended amount of time. Despite this, the foot did not heal. Some Christian missionaries came, and convinced her to convert to Christianity, which, she claimed, improved her condition. This is likely coincidental.
The doctors suggested a skin graft to improve the foot, but she refused. Necrosis was so deep that it permeated the bone and the foot is permanently curved as a result. The leg still shows sign of swelling even more than 24 years after the bite. In most cases, they probably would have simply amputated.
The lady was born in 1948, bore ten children, one of which was born just as she was bitten. She was unable to breast feed or care for the child. Regardless, the daughter has two children of her own now.
Snakebites are bad news. In this woman’s case, the disregard for proper medical care simply made a bad situation worse. She is truly lucky to be alive. If she had died, it is doubtful that the Mgangas would have admitted any responsibility.
I sent our DSS out looking for snake bites, and they found them! We simply asked households if anyone in the household had been bitten by a snake in the past five years. More then 5% of them said “yes” and since we know the locations of the households, we were able to make this cool map. Note that the snake bites tend to cluster around two large areas and are noticeably absent from others.
Kenya hosts many varieties of extremely poisonous snakes included the Puff Adder, the Black and Green Mamba and the spitting Cobra. Snakes are universally feared here and often killed on sight by the locals.
