Consultant Waste Water/Environmental Surveillance (WES)

Site WHO


Wastewater/environmental surveillance (WES) is recommended to track population-level epidemiological features of pathogens of epidemic and pandemic potential. These include the assessment of the disease burden in the community and the capability to monitor a large number of individuals through single-sample testing. Therefore WES will assist in identifying priority pathogens such as Ebola, Marburg, Lassa, Rift Valley viruses etc among the viral hemorrhagic fevers along with COVID-19, bacteria etc. These priority pathogens carry a variety of risks that have a significant impact on public health leading to outbreaks, pandemic as seen during COVID-19.

Therefore, it is crucial to monitor these pathogens in environmental settings to identify their presence and potential routes of transmission early to guide public health interventions. Hence, the main aim is to build or strengthen capacity and use innovative tools (by leveraging gains from the polio eradication programme) to detect and characterize priority pathogens through wastewater and environmental surveillance.


The WHO Regional Office for Africa is engaging international consultant to work on the following Terms of Reference (ToR):

  • Develop and implement research projects in the areas of WES, genomics, bioinformatics, and computational biology across the continent. Environmental monitoring of media such as water, soil, and surfaces – routinely, during outbreaks, or as part of research studies – to identify environmental hazards (e.g., pathogens) and inform remediation efforts
  • WES or fecally impacted surface waters to track the emergence and spread of diseases and targets of public health concern (e.g., antimicrobial resistance) in communities

Technically support the AFRO region to develop or review countries’ National WES Plan and ensure all requirements are met with regards to WES implementation
