  • Background Information

    The virial load of SARS-CoV-2 coronaviruses in different types of clinical specimens can vary dramatically. In general, lower respiratory tract specimens have more viral load than those from the upper respiratory tract (Hu et al., 2020; Wang et al., 2020). A recent study shows that bronchoalveolar lavage fluid specimens contain the highest vial load, followed by sputum, nasal swabs, fibrobronchoscope brush biopsy, pharyngeal swabs, feces, and blood (Wang et al., 2020). As a commonly used procedure for COBID-19 diagnosis, nasopharyngeal (NP) swabs are used to collect specimens from the surface of the respiratory mucosa (Marty et al., 2020). NP swab specimens are valuable materials to study SARS-CoV-2 viruses and the mucosal immune responses triggered by SARS-CoV-2.
