Chain of Infection - Rocky Mountain Spotted Fever
by Jared Marquardt

Reservoir Host
Portal of Exit
Route of Transmission
Infectious Agent
Rocky Mountain spotted fever (RMSF) is a tick-borne disease caused by the bacterium Rickettsial
Any Disease Causing Microorganism
The organism in which the infectious microbes reside
The infected tick resides on the skin of the human body
The route of escape of the pathogen from the reservoir
This disease cannot be transferred between humans, but can be acquired if two people are in the same area together and get infected
Method by which the pathogen gets from the reservoir to the new host
This disease cannot be transferred between humans, therefore there is not a route of transmission
Portal of Entry
The route through which the pathogen enters its new host
An infected tick would bite a human, and therefore the human now has the disease, which was transferred from the tick, through the skin and into the body
Susceptible Host
The organism that accepts the pathogen
Any organism that is in the same area as the ticks
1st Cycle Break
Avoid walking in areas of tall
grass and brush where there
may be ticks

Wear light-colored clothing

2nd Cycle Break
Tuck your pants legs into your socks so ticks can’t get up inside your pants legs

Wear a long-sleeved shirt
and tuck it inside
your pants
4th Cycle Break
Apply insect repellent containing
DEET to your skin

Because DEET lasts only a few hours,
you may need to reapply it

Look for ticks on your body,
including in your hair,
when you return from
hiking or walking
3rd Cycle Break
Spray insecticide containing permethrin on boots and clothing

The effects of this insecticide will last several days
