As the coronavirus has created havoc across the world, scientists at the Centre for Disease Control (CDC) and Prevention added three new triggers to the list of COVID-19 symptoms. Doctors at Chest and King Koti hospitals in Hyderabad have claimed that the new symptoms– Diarrhea, headache and vomiting are responsible for the delayed process of diagnosis and treatment.

Doctors said that the new symptoms have prompted the need to step-up the treatment and also test those people who are suffering from new symptoms and not just the common ones. They further said that the common symptoms -- cough, fever and breathlessness -- are not being noted in patients as earlier, while new symptoms are creating confusion.
