Micobee and Tumatumari are small health clinics in Guyana separated by about five miles. These facilities serve a resident population of 360 as well as 300 miners from small villages along the river. Both facilities are attended by a part time local health worker. These facilities are typical of the large number of health posts scattered throughout the interior of Guyana and most other developing countries.
