My son is aged 35 years, of good health, with no habits like smoking, drugs, alcohol etc. In the last 2 months , he had a lot of official trips to make outside Mumbai. He stays in Mumbai. Immediately on his return to Mumbai after his last trip to Bangalore, he developed High Fever ,reading 103.5 degrees. His fever persisted for a few days. I took him to a Doctor. His blood sample was taken for testing Dengue 8.
