Because the initial symptoms of Newcastle pneumonia are fever, dry cough and malaise, which are similar to those of the flu, it is possible that a person with a cold or fever during an outbreak may be isolated, although this should be determined based on their epidemiological history and nucleic acid test results. For patients with fever who have not been overseas within 14 days before the fever and have not been in contact with patients with Newcastle pneumonia locally, they should generally go to the fever clinic and undergo a nucleic acid test according to the normal process. You can take more rest, drink more water, and take cold medicine under the guidance of the doctor for 3 days, and then if the situation does not ease or even gets worse, it is recommended to go to the hospital again for treatment. However, for feverish patients who have traveled to foreign countries or been in contact with patients with New Coronavirus pneumonia within 14 days before the fever, a chest CT, blood routine, and nucleic acid test will be done after visiting the hospital, and if there is suspected New Coronavirus infection, single room isolation treatment and the next round of nucleic acid test will be performed until the virus disappears and the body recovers.
