Most early stages of New Coronavirus pneumonia involve the respiratory system and typically present with fever, malaise, and cough, while a few individuals have no typical symptoms. Early symptoms of New Coronavirus pneumonia usually last 5-13 days, but the duration of early symptoms after New Coronavirus infection varies depending on the physical condition of the infected person. In children, the early symptoms of NCCP are milder, with high fever common in the early stages, mostly lasting 1-6 days, which is shorter than that in adults. Most of the symptoms last for 3-7 days. If you have been to an area with high incidence of the disease or have been in contact with a patient with Newcastle pneumonia within 14 days before the occurrence of the above symptoms, it is recommended that you go to a hospital for a comprehensive evaluation of chest CT, routine blood tests and nucleic acid tests. If infection has not occurred, it is recommended to take precautions such as wearing a mask when going out, not going to crowded places, disinfecting the indoor environment regularly, and washing hands regularly to reduce the chance of infection.
