An ounce of prevention is worth a pound of cure.
We regularly come into contact with surfaces that are full of germs: keyboards, door handles, money, etc. To help fend off the germs, make sure to have hand sanitizer and disposable biodegradable wipes on hand; use frequently. Look for ones that contain natural ingredients such as tea tree and lavender essential oil.
There are also intimate wipes for those times that you are unable to bathe thoroughly. These wipes are usually biodegradable as well.
Keeping clean can help ward off illness caused by germs.
