If you have a common fever during an epidemic, you will not necessarily be quarantined. It will usually be judged after some analysis, such as whether there has been contact with an infected person or whether the person has traveled to an infected or endemic area. For those with a clear history of contact, the presence of fever will be isolated as a suspected case, followed by a throat swab nucleic acid test. If there are respiratory symptoms, a chest CT will also be done to assess whether it is novel coronavirus pneumonia. In the absence of any epidemiologic history, the presence of fever alone will not lead to isolation, and other investigations will be recommended to find the cause. For example, if the blood test reveals elevated white blood cells and elevated neutrophils, it may be a bacterial infection; or it may be a common seasonal flu. Although influenza is contagious, there are specific drugs, i.e. oseltamivir or neuraminidase inhibitors, which are effective in suppressing the virus, reducing the contagiousness and reducing the risk of severe cases. If influenza is considered, antiviral therapy should be given as early as possible. Source: Dr. Yurai
