A mysterious disease terrorising your community, not infectious but spreading nonetheless, and killing your relatives and neighbours. All you want to do is pack your bags and flee. Worse, when your plight comes to the attention of the health authorities, they are stumped and its not going to be easy or quick to solve.
A recent example of this kind of illness is “nodding disease” (South Sudan, Uganda, and Tanzania), which affects children 5-15 years old: they suffer epileptic seizures which causes their heads to nod, and they end up severely disabled and finally die. The USA’s Centre for Disease Control (CDC) is working to identify the cause: so far, the best guess is that it’s linked to the parasite that causes river blindness combined with an autoimmune reaction, and exposure to chemicals could predispose.
Other examples of non-communicable disease outbreaks
What are the likely causes for these outbreaks? The body of research, as found on databases like Global Health, tells us that they could be contamination of food and water supply, exposure to chemicals or heavy metals in the environment, or even use of traditional medicine.
Mystery liver disease in Ethiopia with a ‘happy’ ending
Can public health authorities in low-income countries solve & stop such outbreaks? Yes. In 2005, in Ethiopia, a 4 year long outbreak of liver disease in Tseda Emba, a small village of the Tahtay Koraro district of Tigray, finally reached the attention of the Tigray Health Bureau (THB). Now, in 2012, the multidisciplinary and one-health approach they initiated has “solved” the mysterious illness, significantly reducing new cases.
The research work was the subject of an entire session at the recent World Congress Public Health (WCPH-2012) in Ethiopia, and is now published as 5 papers in the supplement to April 2012’s edition of Ethiopian Medical Journal (EMJ). [Abstracts to these papers will be available on Global Health]. It demonstrates the relevance of the one-health approach to public health in low-income countries and is a fascinating detective story….
