A patient with co-infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza A virus showed signs of pneumonia. However, the upper respiratory samples were negative in the SARS-CoV-2 RT-PCR test. Metagenomic next-generation sequencing (mNGS) using bronchoalveolar lavage fluid was used to confirm the presence of SARS-CoV-2. A 69- year old patient had fever and dry cough. CT scan of lungs showed ground-glass opacity in the lower right lung. Multiple nasopharyngeal samples were negative for SARS-CoV-2 by RT-PCR but positive for influenza A. A week later the pateint still complained of persistent fever and shortness of breath. Bronchoalveloar lavage samples were then obtained for metagenomic next generation sequencing. Out of the 3,460 sequences, 99.8% identity and covered 98.69% of the SARS-CoV-2 genome NC_045512.2|SARS-CoV-2|Wuhan-Hu-1 (GenBank accession no. NC_045512.2). Co-infection with other viruses may result in false negative test for COVID-19 in upper respiratory specimens.

Metagenomics analysis of three samples from Taiwan revealed the co-existence of Haemophilus parainfluenzae with SARS-CoV-2-positive cases. NGS depths representing exixtence of infections: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7473175/bin/TEMI_A_1782271_SM4509.jpg Haemophilus parainfluenzae (accession number CP035368.2) was the dominant population in metagenomic contigs of CGMH-CGU-07 and -08 samples.

Metagenomic Analysis of a Sample (WIV04) from Wuhan, China, revealed a new coronavirus (2019-nCoV). It caused an epidemic of acute respiratory syndrome in humans. Of the obtained total reads (10,038,758), 1,582 reads were retained after removing the reads from the human genome. Of which, 1,378 (87.1%) sequences matched the sequence of SARSr-CoV
