title: 16S rRNA sequencing of nasal lavage sample of  subject 26 at 4 weeks after SARS-CoV-2 infection
design: We recruited 57 patients experiencing persistent cough after infection during the Omicron wave of SARS-CoV-2 in China following the abandonment of the Zero-COVID-19 policy. Detailed clinical data was obtained, and airway microbiota profiling was assessed in nasopharyngeal swab, nasal lavage, and induced sputum samples collected from them at 4 and 8 weeks after SARS-CoV-2 infection, respectively.
