I would like to talk to everyone about n95 masks and why, if you can't find them, its not that big of a deal.
For my day job I am a Safety Administrator for a midstream oil and gas company. I don't know much about virology, or epidemiology, other than what I learned in college at Texas A&M University (BS in Biology). What I do know is respirators. Mostly due to all the hours of safety classes I have taken in order to get my accreditations.
The N95 masks that everyone is trying to buy is an okay mask for some basic stuff. Some medical professionals might be wearing them if they don't have access to better options. That said the n95 can only be effective if it is used 100% correctly, but, unfortunately, almost nobody can do that thanks to their cheap design and/or user error. If you have n95s you need to make sure that
- they have the right accreditation from NIOSH (NIOSH Approved)
- that you know the exact procedure to get them on or its useless
- that you find someway to get fit tested otherwise they are useless
- that you shave every morning
- that you are aware they will make it harder to breath
- Always dispose, never reuse.
Even if you do all of those things the n95 probably wont keep you from catching an illness by itself. You will need eye protection as well as gloves.
A better option is a full respirator with cartridges designed to keep viral particles out.
These are usually around $400-700 and will protect your eyes as well. You will still need to be fit tested or they are basically worthless as well. Also, you will have to sterilize it after every use and make sure you have enough cartridges as they go out. As great as these are you will still probably get infected, most likely when you clean the mask.
Half masks are also an option, cheaper, but they will not protect your eyes. Fit testing and all that are needed for these as well.
So whats the point?
Well, my point is that buying these and using them probably wont keep you safe. Instead n95s should be put on sick people to keep them from spreading the disease.
The best way to not get this thing is to stay at home and only go out if you absolutely have to. When you do go out do not get closer than 2m to anyone else and don't share an enclosed space with anyone. Always wash your hands before touching yourself in any way. Do not use public restrooms, and do not eat food that hasn't been in your house for a few days. An n95 will generally only make you feel better, but it wont keep you from getting sick.
