Public Health Researchers are working on a project to test Karachi’s wastewater in order to find out the presence and concentration of COVID-19.
The World Health Organisation’s Pakistan office, the National Institute of Health (NIH) and infection disease epidemiologists from the AKU will collaborate on the project, according to Aga Khan University Hospital.
Sewerage surveillance systems will be set up to test sewage water samples of Karachi to detect presence and concentration of COVID-19.
Sewage surveillance systems have the ability of detecting covid-19 in sewage before a person shows symptoms.
For example, people can pass SARS CoV-2 in their stool in the first three to seven days before the infection starts to show any visible symptoms.
Researchers will analyse the amount of SARS CoV-2 particles per millilitre of filtered sewage to estimate the number of cases in the area.
In this way, if the COVID-19 particles in an area’s sewage systems are found to be on the rise, then before the swab tests are taken, health authorities will be prepared in advance to deal with a rise in cases of the infection.
