Patients who present with fever during an outbreak will not necessarily be isolated when they go to the hospital. It is usually necessary to determine whether the patient has a history of travel to the infected area within 14 days, has been exposed to confirmed or suspected cases, and the specific cause of the fever. For patients who have not traveled to an infected area and have not been exposed to a confirmed or suspected case, they can go to a hospital fever clinic and follow the normal procedure when they develop a fever and undergo the appropriate nucleic acid tests. For patients who have been to the infected area or have been in contact with confirmed or suspected cases, two nucleic acid tests are usually required after the onset of fever and if the second nucleic acid test is negative, isolation is not required, but if it is positive, they need to be sent to a designated hospital for treatment. Therefore, personal protection and hand hygiene should be done during the outbreak, minimizing activities in crowded places and wearing protective masks when going out. In addition, there are more diseases that can cause fever symptoms, which may be caused by the common cold or upper respiratory tract infection. Patients may present with fever, cough, nasal congestion, runny nose, etc., which may also be accompanied by dry throat and sore throat. Patients are advised to observe at home, drink plenty of fluids, take rest, and perform physical cooling if necessary. However, if the patient’s symptoms do not improve after several days and are accompanied by other symptoms such as difficulty in breathing and diarrhea, it is recommended to seek medical treatment promptly.
