Reportedly the Centers for Disease Control and Prevention (CDC) has added three new symptoms of COVID-19 - Congestion or runny nose, nausea and diarrhea.  Previously, it had listed the twelve symptoms like fever, cough, shortness of breath, headaches, loss of smell or taste, sore throat, muscle or body aches, fatigue, etc. CDC on its website said that, "This list does not include all possible symptoms. CDC will continue to update this list as we learn more about COVID-19." Meanwhile according to the CDC, the list of emergency warning signs included continuous pain or pressure in the chest, inability to arouse, and bluish lips or face. CDC suggested that, "People experiencing these types of symptoms should not neglect and should seek medical attention immediately."

Symptoms may appear 2 to 14 days after the exposure to Sar-Cov-2, virus which is responsible for the cause of illness. CDC warned that, "Anyone can have mild to severe symptoms. Older adults and people who have severe underlying medical conditions like heart or lung disease or diabetes seem to be at higher risk for developing more serious complications from COVID-19 illness.” The World health Organization said that there are concerns about increasing trends in Africa, Eastern europe, Latin America and other parts of Asia.
