There are a few reasons for the increase in injuries at this time. On top of what I've already explained, injuries can increase because most of us don't do this hard manual work very often, if at all. This leads us to forget how to use certain tools, which can lead to errors. This forgetfulness and making mistakes can increase our probability of injury. Also, harder work can lead to fatigue and other overwork conditions.
It's difficult to know what the sewage and waste circumstances will be in a post-apocalyptic world, but it's safe to assume it won't be as safe as it is now. So getting diseases from these sources will be much more likely. The last reason to have the correct contents of the first aid kit is simple: when you get injured or get sick, chances are there is no hospital to go to travel first aid kit.

Now that we have established the importance of a first aid kit, what should you put in it? There are many fully made first aid kits that can meet your needs, but sometimes you may want to make your own first aid kid or add things to a premade one. Below I've compiled some of the kits that are for sale on Amazon, so take a look at what they have.
There are a couple of things to think about when looking for the essential contents of the first aid kit: First, how big will your first aid kit be? It is probably a good idea to have a large home first aid kit and one that is small enough to be mobile. Second, what kind of medical problems do you and your family have? If you have thyroid problems, it would be a good idea to try to get 6 months or more of your prescription. Insulin can be very difficult to obtain during a disaster, so a long-term supply would be beneficial. You would also need an insulin cooler to protect your insulin. Any other recipes you have that are necessary for your survival must be in the kit. Third, do you have small children? You may want to add specific medications for children. And finally, does your family have any allergies? If the allergy is severe enough (mainly peanuts or bees) to cause an anaphylaxis reaction, make sure you have enough epinephrine to last.
