You hike for a taste of life and not for the contagion of death. Always be ready with your safety kits. Filter your water supply or add solutions to cleanse your bottle of survival. It will also be wise for you to use a drinking tube, so you'll be able to control your drinking spree enough to last for the whole journey. Baking powder and baby powder will also help resist infection or friction while bug repellents are also handy to ward off the insidious mosquitoes and parasites. They may be small but they can do a lot of harm to health.
