13 May 2020 – Application of epidemiological surveillance to identify COVID-19 in wastewater

Type of Intervention: New Tool / Service / Body
Sectors Involved: Health, Research and Development
Level of Jurisdiction: National
Lead People/Agency: National Water Laboratory

Overview: Costa Rica extends Epidemiological Surveillance to Identify SARS-COV-2 in Wastewater. The international scientific community has shown that a varied percentage of patients with Covid-19 disease excrete particles of the new coronavirus in the feces. The National Water Laboratory (LNA) has collected and analyzed samples from different hospitals. At the moment, studies confirm the presence or not of SARS-CoV-2, but later on, the concentration of the virus present in different samples can be measured and comparisons can be made to estimate the virus load in the population that serves the sewer system. For these purposes, the institution manages the purchase of new supplies that would be arriving in the country in June. In addition, long-term studies would show the seasonality patterns that the virus may present.
