Abstract
Severe Acute Respiratory Syndrome – Coronavirus 2 (SARS-CoV-2) emerged in Wuhan, China and spread to more than 114 countries resulting in a pandemic, which was declared by the WHO in March 2020. Tracking the spread of the virus raised a main concern in every country. Many researches proved the presence of SARS-CoV-2 in stool samples of patients, where the genes of this virus gave a positive signal several days prior to the occurrence of symptoms. The fact of viral shedding in stools provides an advantage in utilizing wastewater systems as a tool to monitor the viral prevalence. We tested more than 2900 municipal wastewater samples coming from 49 distinctive area in Dubai, where 28.6% showed positive results. We also looked into the wastewater samples from 198 commercial aircrafts arriving at Dubai Airport, giving a positive result percentage of 13.6%. The presence of SARS-CoV-2 genes was confirmed using TaqPath™ Covid-19 RT-PCR kit, which targets ORF1ab, N gene and S gene. This project shows the significance of utilizing wastewater-based epidemiology (WBE) in monitoring the prevalence of various infectious diseases such as SARS-CoV-2, which can assist the decision makers to determine the level of precautionary measures according to the areas of the outbreak. With this in mind, pricewise, WBE is considered cost-effective when comparing to clinical nasal swabs.
