Abstract

Aim: COVID-19 pandemic has posed an unprecedented pressure on health systems and economies worldwide. Delivery services have grown as an alternative source of revenue for many people. Consumers generally perceive that delivery services are safer than going into a restaurant, because they reduce exposure to other people and their risk of SARS-CoV-2 contagion. There are no studies analyzing viral load or the burden of COID-19 within this population. This study aims to describe the presence of SARS-CoV-2 among food delivery riders in the city of Quito, Ecuador.

Study design: From July and August 2020, bike and motorbike riders self-employed in two of the main online delivery services in Quito, Ecuador, were invited for RT-PCR testing for SARS-CoV-2 detection during the compulsory lockdown due to the COVID-19 pandemic. The Center for Disease Control (CDC) 2019-Novel Coronavirus (2019-nCoV) RT-qPCR Diagnostic Panel was used to identify the presence of SARS-CoV-2 in nasopharyngeal swabs. All samples were processed in the BSL2 certified molecular biology laboratory at Universidad de Las Americas.

Results: A total of 22 out of 145 delivery workers (15.2%) tested positive for SARS-CoV-2. The majority of workers were men (n = 138), the average age of male workers was 32 years-old (±7.3) and 38 years-old (± 10.6) for females. The presence of mild symptoms was reported in only 9 subjects (6%). The calculated viral load was higher among males with 1.31E+08 copies/mL vs 2.30E+06 in females, although this difference was not statistically significant (p value: 0.68, [CI: -53 to -79]).

Conclusions: The self-employed food delivery riders have a high incidence rate of SARS-CoV-2 infection in relation to the national average. It is important to point out that this is the first study of its kind in Latin-American and probably one of the very few in the world. The results emphasize the need for policy makers to look at the pandemic from as many population's sub-groups as possible. Delivery riders are a highly moving population that offer their services to a wide range of clients, including vulnerable populations such as the elderly or those less likely to leave their house for basic needs stoking.
