From December 2017 to March 2018, several missed diagnoses of influenza A(H1)pdm09 using real-time RT¨CPCR were reported in northern Viet Nam. This study investigated how these missed detections occurred to determine their effect on the surveillance of influenza %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6507123/
