If you catch a cold during the outbreak of novel coronavirus infection, its specific treatment should be analyzed. If you have no epidemiological history and no symptoms of chills or fever, and you just have a simple cold with nasal congestion, runny nose, sneezing, and sore throat, you can take some cold medicines by mouth or drink plenty of fluids, pay attention to rest, and avoid getting chilled again, and most of the colds can be relieved gradually. However, it is important to note that if fever symptoms occur, or if there is an epidemiological history of the disease, it is necessary to go to the fever clinic or infection clinic of the hospital as soon as possible for further examination in order to rule out the presence of new pneumonia, because some of the patients with new pneumonia have predominantly cold symptoms, which makes it easy to be misdiagnosed and underdiagnosed. For high-risk groups, early blood tests, chest CT and, if necessary, nucleic acid tests of the new coronavirus in respiratory secretions are needed to clarify the diagnosis at an early stage.
