I sent an email asking for a letter of request almost a week ago and have not received a response, thoughts on how to proceed during COVID? I asked my two of my current Med school faculty for a LOR almost a week ago and I have got no response yet from either. It is making me pretty nervous and I am not sure what I should do now. I wouldn't regularly make this request over email, but our school is currently shut down because of COVID-19. For reference: I asked via email a week ago and the application is due May 1, so about 5 weeks ahead, both are doctors at our affiliated hospital, but in specialties not typically associated w handling the COVID crisis. My application will be much weaker without at least one of these two letters and there is no way the school will re-open before the due date. Any suggestions on how to proceed, or should I start preparing emails to other faculty as well? 
Thanks
With due respect: these people don’t work for you, and you have 5 weeks before deadline.
If they promised letters, one must presume they will write the letters at a time convenient to them.

If you have not heard with 10 days to go before deadline then ask again.
