Insights from wastewater surveillance into testing-related underreporting and hospital-acquired SARS-CoV-2 infections

Michio Murakami, Nobuhisa Ishiguro, Hiroki Ando, Miyako ISHIDA et autres

• There is a discrepancy between sentinel-confirmed cases and wastewater RNA levels. • Reduced levels of clinical testing relate to this discrepancy. • Incidence of nosocomial infections is associated with wastewater concentration levels. • Wastewater surveillance objectively monitors infections regardless of testing …

Wastewater Surveillance Reveals Testing-Related Underreporting and Hospital-Acquired SARS-CoV-2 Infections

Michio Murakami, Nobuhisa Ishiguro, Hiroki Ando, Miyako ISHIDA et autres

Abstract Wastewater surveillance to monitor the incidence of infections faces challenges, in terms of discrepancies with sentinel-confirmed cases. We examined whether testing rates could explain the discrepancy between SARS-CoV-2 RNA found in a City of Sapporo wastewater treatment plant and the number …

Correlation between antibiotic use and resistance of gram-negative bacteria at a university hospital in Japan from 2013 to 2021: a study using the Japan Surveillance for Infection Prevention and Healthcare Epidemiology (J-SIPHE) system

Keisuke Kagami, Nobuhisa Ishiguro, Sumio Iwasaki, Keisuke Taki et autres

Objectives The Japan Surveillance for Infection Prevention and Healthcare Epidemiology (J-SIPHE) system aggregates information related to antimicrobial resistance (AMR) measures. We aimed to investigate the correlation between antibiotic use and AMR at a university hospital from 2013 to 2021 in a time …

Efficacy of a novel SARS-CoV-2 detection kit without RNA extraction and purification

Tatsuya Fukumoto, Sumio Iwasaki, Shinichi Fujisawa, Kasumi Hayasaka et autres

Rapid detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is critical for the diagnosis of coronavirus disease 2019 (COVID-19) and preventing the spread of the virus. A novel detection kit - the 2019 Novel Coronavirus Detection Kit (nCoV-DK) - halves the …

Efficacy of a novel SARS-CoV-2 detection kit without RNA extraction and purification

Tatsuya Fukumoto, Sumio Iwasaki, Shinichi Fujisawa, Kasumi Hayasaka et autres

Abstract Rapid detection of SARS-CoV-2 is critical for the diagnosis of coronavirus disease 2019 (COVID-19) and preventing the spread of the virus. A novel “2019 Novel Coronavirus Detection Kit (nCoV-DK)” halves detection time by eliminating the steps of RNA extraction and purification. …

Sumio Iwasaki, Shinichi Fujisawa, Sho Nakakubo, Keisuke Kamada et autres

We prospectively compared the efficacy of PCR detection of SARS-CoV-2 between paired nasopharyngeal and saliva samples in 76 patients including ten COVID-19 patients. The overall concordance rate of the virus detection between the two samples was 97.4% (95%CI, 90.8-99.7). Viral load was …
