You also don't want to light yourself on fire if you're cold, slit your wrists to drink the blood if you get thirsty, or try to loot the nearest gun store for protection.
Bringing hand sanitizer with you is stupid and ridiculous, and so is social distancing from your family or people who you are with while you're trying to help each other through the disaster. It's idiotic and wrong. Again, water, shelter, warmth, and basic communication are the most important.
Covid is an absolute non-issue in this situation.
