Since the early 2000’s, Nigeria’s Middle Belt has suffered from a series of violent attacks by the Fulani Herdsmen on the non-belligerent, indigenous peoples of Benue state, ultimately displacing villagers from ancestral lands and stripping them of their livelihoods (Ode, 2018). The Fulani Herdsmen are considered semi-pastoralists or nomads and are primarily Muslims, whereas most of the sedentary farmers in the region identify as Christians. As of January 2018, a suspected 170,000 displaced persons had entered the Internally Displaced Persons (IDP) camps set up by the Nigerian government across several states in Nigeria’s Middle Belt. These asylum seekers are not considered refugees by the international community, as they remain within Nigeria’s national borders and unfortunately, this means that the resources and services that are available to IDP’s are often inferior to those of refugees. As highlighted in my previous blog post, substandard conditions in refugee camps, or in this case, IDP camps, often lend way to an array of public health problems - in this case, giardiasis.
The prevalence rate of giardiasis in children was determined in a recent epidemiological survey conducted in Guma’s IDP Camp located in the Benue State of Nigeria. Of the 292 children ranging from ages zero to nineteen that were sampled, 118 of them tested positive for giardiasis (Nyamngee & et al., 2009). That is a prevalence rate of 40.4% in the Guma IDP camp compared to a global prevalence rate of 20-30% for low income countries (Minetti & et al., 2016). The statistic provided by this paper is a bit outdated so it may be possible that the global prevalence rate of giardiasis is lower than 30%. However, you can probably gather that a prevalence rate of 40% is a pretty significant figure.
Giardiasis is a horrible intestinal infection caused by the protozoan, Giardia lamblia (Nyamngee & et al., 2009). The parasite can thrive in both rural and non-rural settings and can cause acute and chronic diarrhea in infected individuals. The most common transmission routes are through contaminated water sources and food. After Giardia lamblia cysts enter an individual via water or food consumption, the cysts settle in the gastrointestinal system and develop into adult protozoans. Sexually mature protozoans reproduce cysts in the GI tract where the viable cysts and trophozoites can then exit through feces. Trophozoites die after leaving the human body but unfortunately, cysts can persist for several weeks in the external environment. According to Nyamngee & et al., epidemiological risks such as contaminated water sources, communal toilets, and public defecation were the most significant factors in giardiasis occurrence in IDP camps.

One of the main takeaways from Nyamngee, et al. is that prevalence of giardiasis differs among various age groups. The most susceptible demographic was children aged five to nine at a prevalence rate of 48.3% (Nyamngee & et al., 2009). The next demographic group of children ten to fourteen years of age had the second highest prevalence rate. Thus, prevalence rates were inversely proportional to age. The other main takeaway is that communicable diseases play out in a more destructive manner in low-income nations and there is a reason why many communicable and neglected tropical diseases are called “diseases of poverty.” In my opinion, the Nigerian government and the international community must guarantee sanitary conditions in informal settlements set up for IDP’s in addition to ensuring the availability of safe drinking water for both consumption and domestic uses. Just because IDP camps don’t receive mass international attention does not mean that they can be neglected; conditions in refugee camps are not that much better but at the very least, they receive international aid and assistance.

    Excellent post. The sources are interesting and you tell a story with a long history but one that is less commonly heard here outside of the Nigerian context.

      Hi Dr. Taylor, thanks for the positive feedback! It's definitely interesting to see how different health outcomes come about when one falls under "international problems" i.e. refugees and the other, under "domestic issues" i.e. internally displaced persons.

Putting a Face on Childhood Diarrhea

The rotavirus is a highly-infectious double stranded RNA virus that serves as one of the most common causes of diarrheal disease in children . The two most common symptoms are severe watery diarrhea and vomiting, both symptoms lasting for 3 to 8 days . Subsequent dehydration of the body causes dryness in the mouth and throat, dizziness, and decreased urination. Infected individuals can transmit the virus through their feces and contract the virus by coming into contact with infected fecal matter; thus, addressing improper hygiene practices that lead to fecal contamination of water sources should be of greatest concern when it comes to rotavirus alleviation in sub-Saharan Africa. In particular, the link between water, sanitation, and health becomes strikingly apparent when examining how children come into contact with infected fecal matter. Unwashed hands contaminated with viral strains of the rotavirus, drinking tainted water sources, or consuming food prepared with unsafe water are ...

The Planeteer’s Introduction to Water and Sanitation

Have you ever wondered what water truly means to you? Thought about what it would mean if you didn't have access to water on a daily basis? How about clean drinking water? As a Californian   I’ve grown up in sunny California my whole life and as much as I love my so-called “golden” state, we’ve definitely had our fair share of water resource management problems. Water use and access in California are often subjects of great controversy and beget bitter sentiments from democrats, republicans, farmers, students, mothers, fathers, and the list goes on and on. As a Brit, you’ve probably seen the agricultural sector of California’s central and inland valley marred by water conservation efforts due to drought remediation interventions. Every time I drive on the Interstate-5 towards San Francisco, I see “Solve the Water Crisis” or “Is Growing Food Wasting Water” billboards littering the side of the highway. Even my family has suffered the costs of California’s water crisis. Ou...

Water and Children

Image 1 :  Map showing the varying risks for childhood stunting across the globe Acute diarrheal infections are one of the most devastating diseases impacting children in resource poor nations.  Although direct impacts such as administering oral medication may be helpful in the short run, interventions in the non-health sector such as securing clean water may have a much more sustainable impact. The United Nations’ new objectives under the Sustainable Development Goals (SDG’s) have started to highlight the importance of a holistic approach to addressing public health issues in regions such as sub-Saharan Africa. Across the world, an estimated 2.4 billion people do not have access to safe water sources and over 800,000 children die from diseases related to poor sanitation conditions each year. I’ve mentioned that diarrheal diseases have the highest impact on young children but you may be wondering in what ways? Besides being one of the leading causes of morbidity, di...
