• Don’t drink water that’s likely contaminated

This includes, for example, water from streams or lakes near
campsites or hiking trails
• Don’t put your fingers in your mouth or eyes
Doing so transmits germs
• Do avoid contact with ticks, rodents and reptiles
Stay away from turtles, snakes, lizards, ticks, mice and other
potential disease carriers
• Do keep up to date with vaccinations

They can protect you from life-threatening infectious diseases
• Do recognize signs of generalized infections

Signs and symptoms of an infection include fever, sweats and chills
For skin infections, look for redness and warmth

Antibiotics don’t help with many common infections, and overuse
encourages the growth of drug-resistant microorganisms
