In the context of a table, we can utilize the json format {'value': '<cell value>', 'location': (row number, column number)} to express a cell's position, where both row and column number commence from 1. Examining the provided table image, identify the locations of the following cells using this format.
Values to locate:
CELL VALUE 1: '1–3 weeks post exposure'
CELL VALUE 2: 'Sleeping sickness, African sleeping sickness'
CELL VALUE 3: '3,500'
CELL VALUE 4: '11,000'
Should a cell be absent in the table, denote its location as 'DOES NOT EXIST'.

The target cell locations are as follows:
CELL LOCATION 1: {'value': '1–3 weeks post exposure', 'location': (5, 2)}
CELL LOCATION 2: {'value': 'Sleeping sickness, African sleeping sickness', 'location': (2, 2)}
CELL LOCATION 3: {'value': '3,500', 'location': (11, 2)}
