The word "microcephaly" comes from the Greek, "small head". But in Pakistan, such children are known as chuas or "rat people".
That's slightly incorrect. It is right that a rat is called a chooha in Urdu but the plural of it is choohay, not choohas (or chuas).
These days, most chuas are intinerant beggars. Travelling up and down the Grand Trunk Road, following a seasonal calender of religious festivals. Each chua is owned, or perhaps leased, by a minder, often a raffish, gypsy-like figure. The Chua-master looks after, and profits from, his chua rather as a peasant might a donkey; together, they may earn as much as 400 rupees per day, about £4. Most people I asked supposed that there are about 1,000 chuas in the Punjab, but no one really knows.
