Apart from the vector-borne diseases, the capital is witnessing a rise in viral fever cases due to changing weather.

"The earliest recognizable symptoms of a viral infection are often fatigue and body ache. This may be followed by the onset of fever. In most cases, fever is accompanied by a sore throat, running nose, nasal stuffiness, and red eyes. A headache is also a common symptom of viral infection. Vomiting and diarrhoea may be present in some cases," said Doctor Rajesh Bhudiraja, Internal Medicine, Asian Institute of Medical Science.
