Which of the following best represents an example of infectious disease spreading via a vector?
Being bitten by an infected mosquito
A group of partygoers hugging and shaking hands
Disease spreading from infected mother to infant via the placenta
Two persons, one of whom is infected, sharing a glass of soda
The Correct Answer is A
A. Being bitten by an infected mosquito: A vector is an organism (e.g., a mosquito, tick, or flea) that transmits pathogens from one host to another. Mosquitoes transmit diseases like malaria, dengue fever, and Zika virus.
B. A group of partygoers hugging and shaking hands: This describes direct contact transmission, not vector-borne transmission.
C. Disease spreading from infected mother to infant via the placenta: This describes vertical transmission (from mother to child during pregnancy), not vector-borne transmission.
D. Two persons, one of whom is infected, sharing a glass of soda: This describes indirect contact transmission through fomites (contaminated objects), not vector-borne transmission.

Correct Answer is A
Explanation
A. Elevated growths with a "cauliflower" appearance: HPV lesions, commonly known as genital warts, have a characteristic raised, rough, and cauliflower-like appearance. These lesions are caused by HPV types 6 and 11.
B. Solitary growth with elevated borders and a central depression: This describes a basal cell carcinoma, which is a type of skin cancer, not HPV-related warts.
C. Thin-walled pustules that rupture to form honey-colored crusts: This describes impetigo, a bacterial skin infection typically caused by Staphylococcus aureus or Streptococcus pyogenes.
D. Vesicles that ulcerate and crust within 1 to 4 days: This describes herpes simplex virus (HSV) lesions, not HPV. HSV lesions appear as painful fluid-filled blisters that rupture and form ulcers.
Correct Answer is A
Explanation
A. HSV-2 is a viral infection that is both chronic and incurable: Unlike gonorrhea (a bacterial infection that can be treated with antibiotics), HSV-2 (Herpes Simplex Virus 2) is a lifelong viral infection with no cure. Antiviral medications can help manage outbreaks but do not eliminate the virus.
B. HSV-2 is extremely expensive to treat: While HSV-2 requires ongoing management, it is not necessarily more expensive than treating antibiotic-resistant gonorrhea, which can require costly treatments.
C. HSV-2, like HIV, can become life-threatening: HSV-2 itself is not typically life-threatening, though it can cause complications in immunocompromised individuals. Unlike HIV, it does not severely weaken the immune system.
D. Once a person has been treated for HSV-2, the person is immune to further outbreaks: This is false because HSV-2 remains dormant in the body and can reactivate, causing recurrent outbreaks.
