ABSTRACT
The control of the COVID-19 epidemics has been one of top global health priorities for the last eighteen months. To that end, more reliable and easy-to-use diagnostic tests are necessary. Young children are still not eligible to vaccination and it is important to find a way to easily test this key population regularly. With that in mind, we evaluated a new innovative easy two-step self-test named COVID-VIRO ALL IN(R) developed by AAZ that uses a sampling nasal sponge instead of a classic nasal swab. Mirroring the previous study conducted on the first generation of COVID-VIRO(R) antigenic self-test, we first performed a multicentre, prospective study on 124 adults and children, in a point-of-care setting. Sensitivity, specificity and overall acceptance of the COVID-VIRO ALL IN(R) antigen self-test compared to RT-PCR on nasopharyngeal samples were evaluated at 93.02%, 100% and 97,5%, respectively. We then performed a multicentre, prospective, usability study to evaluate the ease of use of COVID-VIRO ALL IN(R) in real life on 68 laypersons, all adults. Globally, 99% of them considered the instructions material good, 98% executed the procedure well, and all of them interpreted the results correctly. The usability was then specifically investigated on 40 children and teenagers participants, comparing both COVID-VIRO(R) first generation and the new COVID-VIRO ALL IN(R). All of them found COVID-VIRO ALL IN(R) much easier to use and much more comfortable. For young children, the COVID-VIRO ALL IN(R) self-test appears to be safer (less risk of trauma compare to nasal swabs and no liquid exposure) easier to use than classic COVID self-tests and giving immediate result which is not the case for RT-PCR done on saliva samples (currently done in routine for kids in French schools). It could be an adapted tool for future mass screening campaigns in schools or at home under adult supervision for kids from the age of 3.
