Babesiosis: Malaria-like infection caused
by parasites in the red blood cells. Transmitted by the black-legged tick,
and probably the western black-legged tick.
Symptoms: Fever, chills, headache, muscle pain, anemia. Babesiosis
is potentially fatal, especially in elderly people and those who have
had their spleens removed.
Colorado Tick Fever: Viral disease that
occurs in the western United States. Transmitted by the Rocky Mountain
wood tick and possibly the Pacific Coast tick.
Symptoms: High fever, chills, severe headache, muscle aches, and occasionally
a faint rash which lasts about a week. After a 2-3 day remission, symptoms
may reoccur accompanied by a drop in white blood cells. Complications
include encephalitis, heart problems, and severe bleeding.
Ehrlichiosis: A bacterial infection caused
by the killing of white blood cells. There are two forms of the disease
in humans: human granulocytic ehrlichiosis (HGE), and human monocytic
ehrlichiosis (HME). Transmitted by the American dog tick, brown dog tick,
lone star tick, black-legged tick, and probably the western black-legged
tick.
Symptoms: Fever, malaise, headache, chills, severe muscle aches or
pain, vomiting, anemia, lung infection, decrease in white blood cells,
and elevated liver enzymes. Some people experience neurological manifestations
including seizures, meningitis, confusion, ataxia, cranial nerve palsy,
and change in mental status. Delayed treatment can result in death.
Relapsing Fever: A multi-system disease,
occurs primarily in the western U.S. Transmitted by soft ticks which feed
at night.
Symptoms: Repeating bouts of fever and chills, headache, muscle and
joint pain lasting 2-9 days, alternating days with no fever.
Powassan Encephalitis: Virus that infects
the brain. Transmitted by the Rocky Mountain wood tick, the black-legged
tick can also transmitted the infection.
Symptoms: Flu-like symptoms (headache, fever, fatigue), pain behind
the eyes, and muscle weakness. Neurological symptoms include light sensitivity,
seizures, partial or complete paralysis, hallucinations of the sense
of smell, diminished ability to communicate (aphasia), dementia, and
death.
Rocky Mountain Spotted Fever: Most prevalent
in the eastern U.S. Transmitted by the Rocky Mountain wood tick, dog tick,
and Pacific coast tick.
Symptoms: Flu-like aches and pain, headache, chills, confusion, light
sensitivity, and high fever. A reddish-black rash (measles like) starts
on the extremities and may spread to the entire body. Death can occur
due to delayed treatment.
Tick Paralysis: Potentially fatal reaction
to toxin secreted in the saliva of a female Rocky Mountain wood, American
dog, and lone star ticks.
Symptoms: Headache, vomiting, general malaise, loss of motor function
and reflexes, followed by general paralysis that starts in the lower
body and spreads to the rest of the body. Respiratory failure and death
can occur. In young children, death can occur in one to two days.
Tularemia (Rabbit Fever): Most cases in
the south central U.S., many caused by tick-bites. Transmitted by the
American dog tick, lone star tick, Rocky Mountain tick, and Pacific coast
tick. Other transmitters include deerflies, infected animals, and contaminated
water.
Symptoms: Spikes of severe fever, swollen lymph nodes that develop
into skin ulcers, conjunctivitis, and pneumonia.
Bartonella (Cat Scratch Disease):
Primarily transmitted by cat bites and scratches, new evidence has shown
brown dog ticks as possible transmitters.
Symptoms: Symptoms usually begin with a small red crusted elevated
mark on the scratch or bite site, which can become swollen and discolored.
This is followed by flu-like symptoms, muscle/joint pain, nausea, vomiting,
chills, and occasionally pain in the throat. Main indicators are swollen
lymph nodes, or enlarged lymph nodes around the ears with conjunctivitis.
Serious complications may include inflammation of the heart, abdominal
pain, inflamed or enlarged spleen, skin eruption with open wounds, bone
lesions, hepatitis, and inflammation of the retina and optic nerve.
