AETIOLOGY
This type of microorganism causes Lyme disease, relapsing fever, tularemia, and Rocky Mountain spotted fever.
What is Bacteria
This arthropod is the most common vector transmitting Lyme disease and Rocky Mountain spotted fever.
What is a tick?
This is the most common symptom shared among all four diseases discussed.
What is fever?
These living conditions significantly increase the spread of louse-borne relapsing fever during humanitarian crises.
What is overcrowding?
This chemical method is used to control tick populations.
What are acaricides?
This Borrelia species causes louse-borne relapsing fever.
What is Borrelia recurrentis?
This insect transmits louse-borne relapsing fever.
What is the human body louse?
This hallmark feature defines relapsing fever and involves repeated spikes of elevated body temperature.
What are recurrent febrile episodes?
This environmental factor increases rodent populations and raises the risk of tularemia transmission.
What is poor sanitation?
This simple personal protective measure helps reduce tick bites during outdoor exposure.
What is wearing long sleeves (or using insect repellent)?
This Borrelia species is the primary cause of Lyme disease.
What is Borrelia burgdorferi?
These ticks, commonly called the American dog tick and wood tick, transmit Rocky Mountain spotted fever.
What are Dermacentor ticks?
This early-stage diagnosis is strongly associated with Lyme disease.
What is erythema migrans?
This public health strategy helps prevent outbreaks by identifying cases early and monitoring vector populations.
What is surveillance?
These programs help prevent louse-borne relapsing fever by improving hygiene and eliminating lice.
What are delousing programs?
This bacterium is the causative agent of tularemia.
What is Francisella tularensis?
This disease is commonly found in rural, wooded areas of North America and is known for its bull’s-eye rash.
What is Lyme disease?
This severe complication of Rocky Mountain spotted fever may occur if treatment is delayed.
What is organ failure (or severe vascular damage)?
These social determinants contribute to increased vulnerability to vector-borne diseases in displaced populations.
What are poverty and limited healthcare access?
This environmental health intervention reduces rodent harborage and helps control tick-borne relapsing fever.
What is rodent control?
