Ehrlichiosis is an emerging disease caused by a rickettsia: a type of bacteria that infects dogs, people, and less commonly cats. For dogs in North America and world-wide most cases of ehrlichiosis are caused by Ehrlichia canis (canine monocytotropic ehrlichiosis).1 Transmission is always from tick bites. Although people and dogs often live in close relationship to, and may come in contact with, the same species of tick, E. canis infections in people are thought to be rare.

E canis is most often transmitted by the brown dog tick (Rhipicephalus sanguineus). Infection likely requires several hours of tick attachment to the dog, and clinical signs may not appear for 1—3 weeks or longer.

Rocky Mountain Spotted Fever (RMSF) is a serious tick-borne illness caused by the bacterium Rickettsia rickettsii, and it's transmitted through the bite of an infected tick. While not all ticks carry the bacteria, those that do can transmit it to humans.

How it's spread:
RMSF is spread when an infected tick bites a human and transmits the bacteria into the bloodstream.
The bacteria can also be transmitted if a person's skin comes into contact with the tick's blood or feces during tick removal.

Symptoms:
Fever, headache, and a characteristic rash (often appearing later in the illness) are common symptoms.
Other symptoms may include muscle pain, nausea, vomiting, and abdominal pain. Without early treatment, RMSF can be fatal.

Treatment:
Early treatment with antibiotics, like doxycycline, is crucial for preventing complications and death.
If you suspect you have RMSF, see a doctor immediately.

AI Overview

The risk of getting Rocky Mountain Spotted Fever (RMSF) from a tick bite is low. Only about 1 in 1,000 ticks carry the bacteria that cause RMSF. It's also important to note that the risk of transmission increases with the duration of the tick's attachment.

Here's a more detailed breakdown:

Incidence:
Only a small percentage of ticks carry the bacteria that cause RMSF. MedlinePlus notes that only about 1 in 1,000 ticks carry the bacteria.

Time of Attachment:
The longer a tick is attached, the higher the risk of transmission. While some sources suggest transmission can occur within 24 hours, others state that it typically takes several hours for the bacteria to be transmitted.

Risk Factors:
People who live in or spend time in areas with higher tick populations and are more exposed to ticks may be at a slightly higher risk.

Prevention:
Taking precautions like wearing long sleeves and pants, using insect repellent, and regularly checking for ticks can help reduce the risk of tick bites and, therefore, the risk of RMSF.

Personally, I use all the nosodes I have. And I feed my horses minced garlic for years. They have never had a tick on them.
