COVID-19 - how do I navigate this situation with my advisor? I am a Master's student in epidemiology. It's an insane time in our field right now. Of course, I find what's going on fascinating (that's why I am in this field), but extremely stressful as well. 

I have 2 advisors. My primary advisor is not working on COVID-19 related stuff. So, although she's really busy trying to re-plan all of her classes to be remote and just reorganize everything, she is not responding directly to the outbreak. My co-advisor, however, is on the response team for the outbreak in my country. Basically, she is working with the government to create models to predict the trajectory of the disease. I had a meeting with her 1.5 weeks ago and she said basically all she has on her mind is COVID-19. That was before the world went into quarantine so I imagine things have become even busier for her. 

My primary advisor sent me an email today talking about how to move forward and in the email she mentioned that it does depend on how busy my co-advisor is (but also assured me we would figure this all out). 

Unfortunately, the project I am working on now is a modelling project and my primary advisor isn't a modeller, so it's my co-advisor that needs to move the project forward. I still have other things to do for my thesis, but I am almost done those other things and I am just in the editing stages. I have a lot more to do on my modelling project, but my co-advisor is extremely busy right now. I am finished what she asked me to do a couple of weeks ago and want to send it to her.

Sorry for the long post explaining my situation. My question is, should I send her the things the I have finished or would that be a bit tone-deaf? What should I even say in the email? I don't want to come off as not caring about the biggest health crisis in at least a decade while asking her to review something that's not even related to COVID-19. How should I even frame the email or should I hold off from sending her things for a few weeks? 

If it makes a difference, although I do have an office, I can do 100% of my work remotely (and do usually work from home at least 3 days a week).
As someone who's been out of academia for a while, I would like to offer a different perspective. Yes, occupying your co-advisor's attention when the roof is on fire is tone-deaf. However: you have acquired skills that are obviously in high demand these days, and are thrown into a (hopefully) once-in-a lifetime situation to apply these skills. Especially since you're not on a strict deadline with your thesis, there are now more important things than finishing the thesis at the scheduled time. See this as an opportunity, not an obstacle.

Check if this is okay with your primary advisor, then send a mail to your co-advisor saying that you would be glad to put your thesis on ice and help her with her COVID work if she has anything you could be of help with. If you are a capable student, she probably will.  

Then, when things have calmed down, reevaluate the situation, see what you have learned in the meantime, and continue from there.
