  1. Rodent Infestationand its Effect on Public Health Globally Yvette McPheeters, MPH Student Walden University PUBH: 6165-2 Instructor: Dr. Howard Rubin Summer, 2010

  2. AGENDA • Types of Rats and mice (vectors) • Diseases rodents carry • Number of disease cases • How rats and mice act in the environment • Environmental damages • Preventive measures

  3. RATS AND MICE • Norway Rat (sewer rat) • Roof Rat (black rat) • House Mouse • White-Footed Rat • Cotton Rat • Rice Rat • Deer Rat Childs et al. (1998)

  4. The Diseases Rodents Carry • Bubonic Plague (Black Death) • Hantavirus Pulmonary Syndrome (HPS) • Rat-bite fever • Lassa Fever (Lassa virus) • Leptospirosis • Murine Typhus • Tapeworms • Favus, Ringworm • Salmoncliosis Frantz, & David, (1991) Childs, McLafferty, Sadek, Miller, Khan, DuPree, Advani, Mills, & Glass, (1998). WHO, (2008) Bonner, Schmidt, Belmain, Oshin, Baglole, & Borchert, (2007) Chou, Chen, & Liu, (2008)

  5. Number of Disease Cases Due to Rat and Mice Exposure • The Bubonic Plague • Hantavirus Pulmonary Syndrome (HPS) • Lassa Fever • Leptospirosis • Rat-Bite Fever Bonner et al. (2007) Chou, Chen, & Liu, (2008) WHO, (2008) Childs et al. (1998)

  6. How Rats and Mice Act in the Environment • Diet • Habitat • Biology • Physical Abilities Frantz & Davis, (1991)

  7. Environmental DamagesRodent et al. (2005)

  8. Preventive Measures • Contact avoidance • Environmental hygiene practices • Take precautions to protect against household exposure to rats and mice • Reduce rodent shelter and sources of food inside and outside the home environment • Reduce exposure to rats and mice in the workplace, (2002)

  9. Conclusion • Rats and mice are vectors • These rodents carry over 35 different diseases • Rat and mice exposure occurs worldwide • Rodent activity leads to global infestation and causes global crop damage and economic loss • Taking the necessary precautions can prevent exposure to rodent-borne diseases
