With sun blazing down and people having to stand in the open air, there have been several cases of people fainting, complaining of giddiness and dehydration, and they are being treated at the makeshift hospital at the air show.

A source said primary care was routinely provided for cases of exhaustion but ever since the show began on February 6, at least three ambulances rushed those in need of medical aid to hospital.

The authorities, however, refused to say how many they had treated or the nature of their ailments.
