It's just before noon and tempers are running high as patients try and jostle with each other to get the attention of doctors at a temporarily set up 'fever bay' at the Hindu Rao hospital in North Delhi. The humidity makes matters worse, with many having come from far off places and having to wait for their turn. A team of four doctors try to keep up with the growing number of patients, performing a quick examination, noting down their names and symptoms before passing them on further down the line to another set of lab technicians taking blood samples.
