Yes. Absolutely. Infection will be a serious threat.
I said this before and I am not joking.
The Zombie Survival Guide by Max Brooks is the best possible introduction to all this survival stuff. Just replace ‘zombie’ with ‘rampaging BLM/Freal”. All the survival aspects are sound.
Oh...Tooth brush. Several. Trust me that you do NOT want to have to deal with bad teeth. I have some med issues (Chrons Disease) that led to nutrient absorbtion issues and thus, teeth problems. The last thing you want to deal with after a couple years post SHTF is pulling your own crumbling teeth or having them pulled. Without painkillers.
There is also trenchmouth etc to consider.
