Can Covid-19 be iatrogenically auto-transmitted through combined oropharengeal and nasopharengeal swabs test with one Bar?

Since the inception of the pandemic, almost all countries have been testing Covid-19 via a swab test with one bar (combined OP and NP). They use the same bar - first an oropharynx swab and then a nasopharynx swab- This manner of application causes oropharengeal Covid-19 viruses to be inoculated into the nasopharynx and help grow Covid-19 disease infection in that area as well. We speculate that asymptomatic Covid- 19 carriers can be converted to pre-symptomatic people via auto-transmission iatrogenically. This highlights the critical role of asymptomatic cases in the progression of the ongoing pandemic. Also,infectivity can also be carried through nostrils to nasopharengeal area via manual intervention with one bar.
