Early warning through the detection of SARS-CoV-2 viral fragments shed by infected or recovering individuals, symptomatic as well as asymptomatic, in the stool and sputum would aid in putting in place prompt control measures to prevent COVID-19 spread in the community. One such early detection method is wastewater surveillance.<\/p>\n<p>In November 2020, National University of Singapore (NUS) Environmental Research Institute (NERI) initiated the COVID-19 wastewater surveillance programme in NUS campus hostels and residential colleges. The programme was conducted in collaboration with Singapore&#8217;s National Environmental Agency (NEA) as a part of the national effort in the monitoring of SARS-CoV-2 in the community.<\/p>\n\t\t\t\t<img decoding=\"async\" src=\"https:\/\/nus.edu.sg\/neri\/wp-content\/uploads\/2024\/02\/Pic_7.png\" alt=\"Auto-sampler used around the campus\" itemprop=\"image\" title=\"Pic_7\" onerror=\"this.style.display='none'\"  \/>\n\t\tAuto-sampler used around the campus\n\t<h4><strong>Wastewater sample collection<\/strong><\/h4>\n<p>Auto-samplers have been deployed around NUS Kent Ridge campus and are pre-set to collect wastewater at selected times during the day (Picture 1).

For our analysis, the N gene (nucleocapsid) of SARS-CoV-2 genome is used as the target sequence for the detection of the SARS-CoV-2 virus.<\/p>\n<p>Results are reported within 24 hours for follow up action, which in the case of positive detection, leads to swab testing of the residence of the affected hostel or dormitory and isolation of the positive cases.<\/p>\n\t\t\t\t<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/nus.edu.sg\/neri\/wp-content\/uploads\/2024\/02\/Pic_1-3-300x227.png\" alt=\"A researcher working in a Biosafety Cabinet (BSC) during sample processing.\" itemprop=\"image\" height=\"227\" width=\"300\" title=\"Pic_1\" onerror=\"this.style.display='none'\"  \/>\n\t\tA researcher working in a Biosafety Cabinet (BSC) during sample processing.\n\t\t\t\t<img decoding=\"async\" src=\"https:\/\/nus.edu.sg\/neri\/wp-content\/uploads\/2024\/02\/Pic_6-1-300x227.png\" alt=\"Wastewater team receiving their national awards\" itemprop=\"image\" title=\"Pic_6\" onerror=\"this.style.display='none'\"  \/>\n\t\tWastewater team receiving their national awards\n\t<p>In 2023, the Wastewater Surveillance team were awarded two national awards, the <strong>&#8220;COVID-19 RESILIENCE&#8221;<\/strong> <strong>Medal<\/strong> and the <strong>&#8220;COVID-19 RESILIENCE&#8221;<\/strong> <strong>certificate<\/strong> by the Singapore government for their hardwork and direct participation in Singapore&#8217;s fight against COVID-19<\/p>\n<p>As Singapore has transitioned to endemic COVID-19 status, sample analysis has been diversified for multiple other purposes (i.e. other viral target detections, variant analysis and modelling comparison across the variants).<\/p>\n\t<p>For more details, please contact: <a href=\"https:\/\/www.eng.nus.edu.sg\/cee\/staff\/gin-yew-hoong-karina\/\" target=\"_blank\" rel=\"noopener\">Professor Karina GIN Yew-Hoong<\/a> | E-mail: <a href=\"mailto:ceeginyh@nus.edu.sg\" target=\"_blank\" rel=\"noopener\">ceeginyh@nus.edu.sg<\/a><\/p>\n\n","protected":false},"excerpt":{"rendered":"<p>NUS Community COVID-19 Wastewater Surveillance Programme Singapore has deployed numerous management controls to tackle the spread of COVID-19 pandemic since 2019, namely contact tracing, circuit breaker and travel restrictions.
