Confirmation of novel coronavirus pneumonia requires one of the following pathogenic evidence: 1. Positive real-time fluorescence RT-PCR for novel coronavirus in respiratory specimens or blood specimens; 2. Sequencing of viral genes in respiratory specimens or blood specimens that are highly homologous to known novel coronaviruses. Patients usually cannot confirm the diagnosis of novel coronavirus pneumonia by self-screening. However, patients can determine if they are likely to have coronavirus pneumonia based on their symptoms and any history of exposure or exposure. If highly suspected, the diagnosis can be confirmed by visiting a sentinel hospital based on the above tests.
