Question

11. (8 pts) Information about Lyme Disease is provided in the following section. After studying this information, outline the chain of infection by identifying the reservoir(s), vector, mode(s) of transmission, and portal(s) of entry 11.A. Reservoir(s): 11.B. Vector: 11 .С. Mode of transmission 11.D. Portal of entry: Lyme Disease information Lyme disease is caused by the bacterium Borrelia burgdorferi and is transmitted to humans through the bite of infected blacklegged ticks (also called deer tick). In the northeastern United States, these infected ticks primarily come from the white-footed mouse (Peromyscus leucopus), but chipmunks (Tamias striatus), short-tailed and masked shrews (Blarina brevicauda and Sorex cinereus), and eastern gray squirrels (Sciurus carolinensis) also serve as infectious hosts Typical symptoms include fever, headache, fatigue, and a characteristic skin rash called erythema migrans, If left untreated, infection can spread to joints, the heart, and the nervous system. Lyme disease is diagnosed based on symptoms, physical findings (e.g., rash), and the possibility of exposure to infected ticks; laboratory testing is helpful if used correctly and performed with validated methods. Most cases of Lyme disease can be treated successfully with a few weeks of antibiotics Steps to prevent Lyme disease include using insect repellent, removing ticks promptly, applying pesticides, and reducing tick habitat. The ticks that transmit Lyme disease can occasionally transmit other tickborne diseases as well

Answer 1

Answer: The Lyme disease have symptoms such as :

• Fever
• Fatigue
• Rashes
• Headache

Reservoir: The infected black legged ticks are mostly the cause of the Lyme disease which carries bacterium burgdorferi.

Victor: The most common vector is the Ticks.

Mode of transmission: The bite of tick, mosquito as well as gray squirrels are the major cause of the transmission.

Portal of entry: The bite of ticks penetrates the skin and leads to the infection.
