I have submitted a manuscript on COVID-19 to a scientific journal in mid-2020. Since then, I have not heard from the journal, although the status says 'Under Review'. As the publication is related to COVID-19, I believe that it is imperative to disseminate the publication as soon as possible once it is accepted. However, as it has been more than half a year, I am afraid that my manuscript's findings are obsolete once it is published, especially considering that evidence related to COVID-19 is quickly expanding.
I have posted the paper to a preprint database. However, I believe that it is important for the peer-reviewed publication to be disseminated at the earliest. In this regard, I have tried contacting the editorial office several times, but I have not received any replies yet. I am afraid that the editorial process may cost me my publication, especially considering that it has been more than half a year since I gathered the evidence.
Is there any suggestion on what I should do?
