Delhi recorded 229 H1N1 cases during this time last year, as compared to 1,349 cases this year, marking six fold rise, according to NDTV.

What to do if you test positive for H1N1

Those diagnosed with H1N1 should isolate at home for two or three days and use a face mask, according t Dr Sinha . If you get the infection, immediately contact the doctor about the treatment.

Dr Atul Kakar, Chairperson, Internal Medicine, Sir Ganga Ram Hospital, told ANI that Delhi is witnessing a seasonal increase in viral respiratory infections, with many patients reporting flu-like symptoms. "Many of them have high-grade fever, which has been running for a few days. A few of them have cold and cough; many of them complain of joint pains, muscle pain, extreme weakness, runny nose and throat pain. This is a type of trend which we are now seeing, especially during this post-rainy season. So, the number of patients is definitely much more," he said.
