Any Porth in a Storm: The Long-Distance Walk that Goes South (2021), a travelogue by Oscar Burton, has a chapter with the title Folie à deux, referencing meeting another person dressed identically and with the same equipment who was also walking the 1000 km South West Coast Path in England. It is suggestive of the mental decay of the protagonist which becomes evident later in the story. The upcoming DC Comics film Joker: Folie à Deux, a sequel to Joker (2019), shares its subtitle with the disorder. Six Feet Under Season 4, Episode 3 (2004), George mentions Folie à deux to Ruth.

Basic sanitation is necessary to reduce fecal-oral contamination and the impact of environmental enteropathy in the developing world. Treatment
Once diagnosed, tropical sprue can be treated by a course of the antibiotic tetracycline or sulphamethoxazole/trimethoprim (co-trimoxazole) for 3 to 6 months. Supplementation of vitamins B12 and folic acid improves appetite and leads to a gain in weight. Prognosis
The prognosis for tropical sprue may be excellent after treatment. It usually does not recur in people who get it during travel to affected regions. The recurrence rate for natives is about 20%, but another study showed changes can persist for several years. Epidemiology
Tropical sprue is common in the Caribbean, Central and South America, and India and southeast Asia. In the Caribbean, it appeared to be more common in Puerto Rico and Haiti. Epidemics in southern India have occurred. History
The disease was first described by William Hillary in 1759 in Barbados. Tropical sprue was responsible for one-sixth of all casualties sustained by the Allied forces in India and Southeast Asia during World War II. The use of folic acid and vitamin B12 in the treatment of tropical sprue was promoted in the late 1940s by Dr. Tom Spies of the University of Alabama, while conducting his research in Cuba and Puerto Rico. == References ==
