Guest-of-Honour, Mr Tharman Shanmugaratnam, President of the Republic of Singapore, presented the Lee Kuan Yew Water Prize 2024 to Professor Gertjan Medema at the Award Ceremony and Banquet held at The Clifford Pier, The Fullerton Bay Hotel earlier today.

Professor Medema is awarded for his breakthrough research and discovery, and significant contributions in the field of wastewater-based epidemiology (WBE). His research revolutionised the application of WBE for virus detection in wastewater during the COVID-19 pandemic.

With the emergence of COVID-19 in early 2020, Professor Medema, a renowned microbiologist and an expert in water quality and health, and his team, recognised the need for early detection and monitoring, and began collecting wastewater samples across the Netherlands to test for the SARS-CoV-2 virus. He quickly focused his team's research on curbing the spread of the virus in the community through wastewater surveillance. The results were promising when evidence of the virus was detected in the wastewater of several cities even before they were officially reported in these cities.

Professor Medema's work has been foundational in establishing WBE as a tool for public health surveillance during the pandemic. The impact of his work was evident from his first publication in this area which garnered substantial attention with over 1,400 citations and more than 34,000 views between 2020 and 2023. Wastewater surveillance has since been adopted worldwide as a powerful tool for the early detection of diseases like SARS-CoV-2, even before cases are reported through clinical testing. This in turn provides valuable insights into the prevalence of the virus in a community, and a proven cost-effective and non-invasive method for tracking the spread of the disease.

Launched in 2008, the Lee Kuan Yew Water Prize honours outstanding contributions by individuals or organisations towards solving the world's water problems by developing or applying innovative technologies or implementing policies and programmes which benefit humanity. The Lee Kuan Yew Water Prize is one of the key highlights of the Singapore International Water Week (SIWW).
