Leptospirosis Risk Factors
Disease Risk Factors
A risk assessment can determine which vaccination program a pet needs. Chances of being infected by a disease are based on several factors:
Location
Many diseases are more prevalent in certain areas of the country.
Age
Young animals are at higher risk for many diseases because their immune systems are not "primed" to respond.
Exposure to the outdoors
Pets that spend even a few minutes outdoors may come into contact with opossums, mice, skunks, raccoons or their habitats. These animals, along with other cats and dogs, have the potential to transmit infectious disease. However, even indoor pets may be at risk if their owners unknowingly carry disease-causing agents into the house on shoes or clothing.
Prevalence of mosquitoes and/or ticks in your area
Mosquitoes and ticks are common carriers of disease.
Travel
It only takes one exposure for your pet to get sick. Before you travel, ask your veterinarian if the destination poses any threat to your pet.
Pets that are not spayed or neutered
"Intact" pets are more likely to roam and then come into contact with other diseased animals.
Pets that drink from standing water outdoors (ponds, puddles, etc.)
Microorganisms in standing water can cause serious diseases, such as leptospirosis in dogs and giardiasis in dogs and cats.
Pets that go to a groomer, boarding facility, or dog or cat shows
Disease-causing agents can remain in combs, cages, towels and other items.
Pets that are used for hunting
Hunting dogs are particularly susceptible to the exposure of diseases carried by wild animals, as well as those spread by ticks and mosquitoes. Diseases of concern include Lyme, leptospirosis and heartworm.
