Activities that bring the population into areas where tsetse are present include the cultivation of crops (sorghum, sesame, sweet potatoes), fishing, collection of wood and beekeeping. The Mandoul area is a historical focus of sleeping sickness. It was included in the âsecteur de prophylaxie numÃ©ro 3â created in 1919 and was visited by the medical teams led by Gaston Muraz in 1928 [9, 10].
The average person is awake for about 14 to 16 hours per day. Most could extend that to about 20 hours if they were to stay up later; up to 40 hours is easy once a person getsâ¦ beyond the 24 hour mark; longer than 60 hours (staying awake straight through two nights and three days) is rare, but doable; the record is 264 hours or 11 days straight.
Indeed people seem to be able to function with very little sleep for prolonged periods of time, albeit not happily. Randy Gardner in 1964 showed that even after 264 hours (eleven days!) of total sleep deprivation he was able to continue to function. With a relatively short period of recovery sleep (about 14 hours) he showed no lasting negative effects. Even longer periods of sleep deprivation have been reported.
