Cases of viral fever have been reported among children in Delhi. General Pediatrics Director of Madhukar Rainbow Children Hospital Dr Nitin Verma on September 8 said that few cases of dengue and H3N2 have been reported in the past week. "It's linked with monsoon. So based on what we've seen, I think dengue has started. But I've had few cases of H3N2 (form of Swine Flu) which is a different kind of viral. Can be diagnosed by simple throat swab,” he said.
