There is usually an incubation period after a Neoplasmosis infection, ranging from a short period of three days to a long period of seven days, and even up to two weeks, with the longest recorded period being 21 days. If a New Coronavirus infection is found, the common test is still a nucleic acid test, or a blood test for antibodies, to determine if the infection is New Coronavirus through effective screening. Before the test is done, early infection will have symptoms to be alerted, such as fever of 37.3°C that gradually worsens and is not relieved by the application of antipyretics, dry cough, headache, and also abnormalities in smell and taste, and diarrhea. When these symptoms occur, it is important to go to the fever clinic for viral nucleic acid testing, so as not to mistake it for a common cold and miss the period of early detection and early treatment of the new coronavirus.
