A friends Uncle was not feeling well and saw a doctor in Asansol. The doctor told he will be fine with a few crocin and sent him home without testing. He then travelled to HYD to see a liver specialist. They did a quick test when they saw the symptoms and he tested positive. He then flew from HYD to MAA to CCU and travelled home by train. All the while he was psoitive and knew it. Didn't want to be stranded in HYD. God knows what others are doing in domestic travel, with or without symptoms.
