==Differential Diagnosis==
==Differential Diagnosis==
The most common presentation of coronavirus infection is the "common cold", and over 100 serotypes of viruses have been known to cause the common cold. [[Rhinovirus]] is the cause in about 30-50% of cases, coronavirus about 10-15% of the cases. Other viruses include [[respiratory syncytial virus]] (RSV), [[influenza]] and parainfluenza viruses.

==Evaluation==
==Evaluation==
Nasopharyngeal swabs can be done which can be used for reverse transcriptase PCRs and immunofluorescent antigen assay. However, cost can be a limiting factor, and in patients with symptoms of the common cold, this testing is not indicated.
*Generally no evaluation indicated
*If needed, nasal swabs can be sent for PCR and immunofluorescent antigen assay


==Management==
==Management==
There is currently no recommended treatment for corona virus infections other than supportive care. During the 2002-2004 SARS outbreak, several antiviral agents were created, but their efficacy was never clearly established.
