In summary, Duangpetch Promthep, a captain of the football team rescued from a Thai cave in 2018, has passed away in the UK. Initial reports suggested it was due to an accident, but this article states he was found unresponsive in his dorm room. This situation is reminiscent of a Thai cave diver who died a year after the rescue from an infection he acquired during the rescue. Similarly, mathematician Ramanujan also fell ill while in England, likely due to the harsher climate exacerbating a pre-existing condition.
I know that one of the Thai cave divers died a year after the rescue from an infection he got during the rescue. Perhaps this is something similar though it seems unlikely.
It also reminds me of Ramanujan who traveled from India to England and contracted hepatic amoebiasis likely due to the harsher English climate exacerbating a condition he had from dysentery.
