> It's what happens when your public health system is overloaded. Every single thing that requires that system (i.e. more or less any healthcare situation that can't be resolved via teledoc or its equivalent) is now a potentially fatal situation. People die from COVID-19 because of the overload, but they would also die from car accidents, knife accidents, serious bacterial infections and more - all of which may have been successfully treated had the system not been overloaded.

It is believed that SARS-CoV-2 can easily mutate to evade current vaccines, and it is just a matter of time before it happens. People with chronic illnesses, along with the disabled, really need to be thinking in the very long-term, wherever they reside.

I have 2 rare immune-mediated neurological diseases affecting my peripheral nervous system, plus type 1 diabetes (autoimmune and insulin-dependent). I live in Croatia, and I am culturally American. I hold dual citizenship in the US and the European Union (Croatia). I left for Croatia right at the start of the pandemic. I feel so lucky, and quite guilty, that my health has improved during the pandemic, thanks to Croatia. Many of my chronically ill and disabled American friends have become so much more sick during this pandemic. I am so worried for them, and I am fighting every single day for them.

The fear is real and will never go away: I now use a device that is much better and efficient than an N95 or KN95 mask when I am around people. It is called a PAPR (powered air purifying respirator) and the device filters out 99.8% of impurities. I will probably do this for the rest of my life, as getting sick is just not worth it. For people who have health issues, this is something to very seriously consider.
You can easily die from having to defer medical care, and I cannot afford to be in that situation. That is why I decided to get a PAPR. Mine can be worn in a hospital bed, 24/7, including when lying down, and the battery lasts for 14 hours. You can also charge a spare battery while the PAPR is in use, and the PAPR that I have uses a standard USB-C charger, and the spare battery itself is inexpensive. The PAPR I have is called the Optrel Swiss Air [1]. It is a PAPR with a really nice mask form-factor, but it does not require a qualitative fit test (which N95 masks and other tight-fitting masks do) to ensure its seal and filtering capability. It filters 99.8% of impurities. Unfortunately, it does not have any source-control, as it has exhalation valves. But, I got a hoodie-styled balaclava which I put over the mask of the PAPR [2], for source control. This is probably the best PAPR to use if you are chronically ill and need protection long-term.

There is another PAPR worth looking into that is innovative and extremely cool looking, called the CleanSpace Halo [3]. It also has source control features [4][5], which makes it a good choice. However, it requires a qualitative fit test, to ensure proper fit, so filtration occurs at the guaranteed rate. But, the tight fitting mask affords it 99.97% filtration protection. You also have to be more careful when donning (putting on) the mask, to ensure that you have a proper seal, so that its filtration is guaranteed, for your safety, compared to the Optrel Swiss Air. It appears that you can use it lying down (but I am not sure). However, the seal of the mask (it is supposed to be a tight-fitting mask with a strong seal all the time--the Optrel Swiss Air does not have this issue) could be compromised very easily by lying down. So, the Optrel Swiss Air is probably a better choice, especially as it is does not require a tight seal. Also, the Optrel Swiss Air is a very small backpack device, so there is almost no weight on your neck, unlike the CleanSpace Halo. The CleanSpace Halo is extremely neat though!
