Zoonotic Diseases Spread from Animals to People
Members of pet-owning households have a greater risk of tick bites than those without pets.
By Lonnie Marcum
What do the following recent news stories have in common?
- Child who visited county fair is Michigan’s first swine flu case of 2017
- Hantavirus confirmed in Reno, Nevada
- Rabies found in dead raccoon in North Carolin
- Lyme disease risk remains high into fall and winter in Connecticut
- They all have to do with zoonotic diseases—those that are spread from animals to people. In fact, according to the CDC, zoonotic diseases account for over 60% of all communicable diseases causing illness in humans.
Some zoonotic diseases, like rabies, are transmitted by the bite of an infected animal. The rabies vaccine for pets has greatly reduced the number of cases of the disease in the U.S. However, the CDC estimates that 40,000 people per year require rabies treatment, primarily after exposure to bats and other wildlife.
Other zoonotic diseases come from direct contact with an infected animal. For instance, you might get salmonella from handling a baby chick, chicken, duck, turtle, or snake.
Another mode of transmission is through contact with animal droppings, saliva, or urine. Hikers and campers may be at risk of hantavirus from rodent exposure in recreation areas, especially in the Southwest.
Insects and arthropods (like ticks) provide another route of transmission for zoonoses. The infections they carry are known as vector-borne diseases. Lyme disease is currently the most common vector-borne disease in the U.S., affecting more than 300,000 people annually.
The Lyme bacterium is spread when a tick (the vector) feeds on an infected animal like a mouse or a squirrel and then later transfers the illness to a human. According to the CDC, 94% of all vector-borne diseases in the U.S. come from tick bites.
Mosquitoes also transmit zoonotic diseases. The World Health Organization (WHO) estimates that mosquitoes infect more than 700 million people per year, causing in excess of a million deaths—with nearly half of those fatalities caused by malaria. While malaria was eliminated from the US in the 1950s, there are still 1,700 cases reported annually, almost all due to recent travel.
Farmers, ranchers, and veterinarians are at an increased risk for zoonotic infections due to their proximity to animals and outdoor areas where ticks and mosquitoes thrive. Examples of diseases associated with animal husbandry are leptospirosis from horses, anthrax from cattle, Q fever from sheep, brucella from goats, cysticercosis from pigs, and Influenza A from chickens.
Veterinarians are at an obvious risk because they treat sick animals. Bartonella is particularly easy to catch as it can be transmitted from fleas, ticks, or the scratch of a cat. Cat bites are also common in veterinary practice and can result in abscess, septic arthritis, meningitis, even death.
Leptospirosis, one of the most widespread zoonotic diseases in the world, can infect a wide range of animals including rodents, dogs, and cats. It can be easily transferred to humans by contact with urine, saliva, or feces.
Food Handling and Consumption
Zoonotic disease can also be transmitted though consumption of undercooked foods. Examples of this are Ebola from bushmeat (non-domesticated animals), trichinosis from pork, E. coli from beef, salmonella from poultry, Listeria from cheese, and tuberculosis from unpasteurized milk.
Food preparation can be another mode of exposure. The flesh-eating Vibrio bacteria can be acquired from cleaning fish or shellfish. It affects nearly 80,000 people, resulting in about 100 deaths per year in the U.S.
Risk for Pet Owners
Pet owners are also at an increased risk for zoonotic diseases. For instance, giardia can be transmitted by touching contaminated dog feces, pet rats can infect their owners with hantavirus, turtles can carry salmonella, chlamydia is common with pet birds, and many small animals carry ringworm.
A recent outbreak of Campylobacter, linked to puppies sold through Petland, sickened 55 people in 12 different states and hospitalized 13.
Due to proximity to animals and the outdoors, pet owners are also at increased risk for vector-borne diseases. A recent study demonstrated that when compared to households without pets, pet-owning households had nearly twice the risk for finding crawling ticks, and 1.5 times the risk of finding ticks attached to family members.
The “One Health” Approach
“One Health” is a concept that promotes collaboration among scientists
“One Health” is a concept that promotes collaboration among scientists from many different specialties to achieve the best health for people, animals, and the environment.
The One Health approach recognizes that animals and humans are part of a global community. Proximity to animals, travel, and changing climate are all factors that affect the prevalence of disease. For this reason, One Health teams include physicians, veterinarians, ecologists, and many others acting on regional, national, and global levels to achieve optimum health.
Examples of this include when veterinary records are used to predict Lyme disease, or when health officials successfully reduced the transmission of Rocky Mountain spotted fever on Native American reservations by putting flea/tick collars on stray dogs.
As with all disease, prevention is key. The best method for preventing infection is to avoid exposure. However, if you own pets, or live, work or travel in an environment where you are exposed, there are several steps you can take to reduce your chances of becoming infected.
- Always use safe drinking water
- Protect yourself from ticks and biting insects
- Keep pets healthy and vaccinated
- Use flea/tick repellant on pets year round
- Vaccinate against preventable illnesses
- Wash hands and surfaces after handling raw food
- Wash your hands after touching animals

Caren and Victor’s Lyme Disease Story:
Caren grew up on the East Coast, Victor grew up in the Midwest of the U.S. They were both exposed to ticks in childhood. Caren developed a rash at age 14 while visiting Cape Cod MA, very close to the time and place Lyme was identified (Lyme, CT). She began to develop a weak immune system in the years following the rash. Her immune system crashed at age 30; when her first child was nearly 2 yo. Caren experienced crippling arthritis in her joints and became profoundly disabled at 30 years old. She did not know why she lost the use of her hands, legs and voice sporadically during the following decades; or why she experienced constant searing pain in her nerves and bones over the ensuing years.
Victor gave up full time ministry, his life’s passion, to provide medical care for his beloved wife. When Caren’s health collapsed at age 30, he left the pastorate to provide medical insurance to his wife. Over the next 2 decades they spent at least $500,000. seeking a diagnosis and treatment for Caren’s many difficulties. Victor built a business as a General Contractor. In the year 2000 Victor’s health began to fail. He was his own boss; so he was able to schedule his jobs around his declining health. Both Caren and Victor were given the diagnosis of Fibromyalgia in 2001. This answered some of their concerns, but it became clear over the next decade that there were more questions yet to be answered.
In 2009, Victor was offered an opportunity to minister full time again- his dream profession and heart’s desire. They moved 500 miles away from friends and family to find that the job was no longer available. Caren’s health took a turn for the worse in 2011; she saw a Dr. who tested her (for the 1st time) for Lyme Disease. She tested positive. Victor was then tested with the same result. They embarked upon 3 years of intensive antibiotic treatment which may have helped, but caused far worse complications including a heart attack, Sepsis, Peritonitis and others. Each of them came close to death on several occasions. They have been treated for Lyme and the co-infections of Babesia, Bartonella and Mycoplasma.
Their battle continues. Every day is a challenge. Caren likes to say, “we don’t know how we will make it each month, but somehow some way God manages to provide for our needs.”. Their medical expenses remain high, they live off of one disability check, yet still they manage to give to others through the ministry of Prayers for Pets and other community service endeavors. Caren and Victor believe that God put them on this earth to serve their fellow souls; they do this to their best ability every day as the Lord allows. They appreciate your prayers.

Getting a Positive Diagnosis for Lyme:
A clear cut diagnosis for Lyme Disease can be elusive; Lyme hides in the brain and throughout the body. It is very hard to eradicate even when treated immediately because of its ability to hide itself. If you believe that you or a friend could have Lyme based on long standing illness; we recommend getting tested through Igenex Labs, they are the current gold standard; meaning that false negatives are less likely through them. We suggest that if Lyme is a suspected cause of symptoms; it is best to read as much as possible before embarking on treatment. If it is possible to see a Lyme Literate doctor (LLMD), that is also recommended; but a doctor alone is not enough to fight the battle of Chronic Lyme. People who suspect they have Lyme must become researchers and advocate for their own health, but a good LLMD can be an advisor. Lyme is complicated; there is no one fix. If Chronic Lyme is diagnosed it will take many lifestyle adjustments to cope with the disease.

C & V’s story Update: answer to a friend’s question about how God healed Caren’s voice: June 25, 2018:
<I don’t know if you knew that I sang professionally for close to a decade; we met when I was largely voiceless I think? I was that way (sans voice) for 20 years. From my late teens thru my late twenties I sang professionally at a number of jobs. At one time I sang with the New Mexico Symphony Orchestra and chorus. We did a tour with Dave Brubeck the jazz musician with his cantata written for New Mexico. After I married Victor and became a Christian we joined the Liberated Wailing Wall (singing group) (that may be us pictured in front of the first bus they ever had in ’80) we toured the world and US for a year-and-a-half. I sang my last concert with JfJ the night before I gave birth to Josh. About a decade after that I lost my voice for 20 years to Lyme disease. Just prior to losing my voice I recorded an album with my friend Tammy. You can hear me sing behind Tammy (the soloist) on the high harmonies.
Of course I wasn’t diagnosed with Lyme disease until 2012 (1st bitten in 1970). Both Victor and I have it. We went thru brutal treatment for 5 years; we are hopefully on the other side of that. It has left us depleted in many ways. I did much reading about vocal issues over the two decades when my voice could not be heard above a whisper. It was 2016 when I found an article which actually tied vocal cord paralysis to Lyme disease. I had scheduled about a month ahead to see an ENT to have my voice assessed to see if I could qualify for some kind of help in getting a device to enable me to be heard on the telephone. I had not had a vocal assessment since 2007 when I was told it was basically incurable.
The date of my appointment my voice suddenly got better and I was able to speak and be heard clearly. That would happen from time to time as you may recall; I thought it was just another one of those times. When they looked at my larynx with a scope they said it was perfectly fine. God had completely healed it that morning! The only time I have lost it since that day was when my mom nearly died in December of ’17. That only lasted a day or two. If I trained myself to sing again I probably could but I don’t really care enough to go through the effort! Lol my singing voice defined me for 2/3 of my life, it doesn’t define me anymore. I am now defined as a child of God who is loved by him. That is all the definition I need.
