Hooked up to a drip, wearing just a nappy and a forlorn expression, the tiny infant stares out through the bars of his cot at the frenzy of activity around him.
A few feet away, a nurse makes up a bottle of formula while another prepares a bath. On a nearby table lies a thermometer, a blood-pressure gauge and bottles of medication.
The scene is typical of any infant care unit and the staff are dedicated to saving their tiny patients. The only difference is that these 'babies' are not human but infant orang-utans.
