Which statement about Weil's disease is supported by the material?

• A. It is associated with fever as a major symptom
• B. It is primarily a skin infection
• C. It is transmitted by mosquitoes
• D. It is caused by Vibrio cholerae

Answer: (A)

Weil's disease is the severe form of leptospirosis caused by Leptospira interrogans. It typically follows exposure to water or soil contaminated with the urine of infected animals, with entry through breaks in the skin or mucous membranes. A hallmark feature is fever, which often presents abruptly along with muscle pains, headache, and conjunctival suffusion. As it progresses, liver and kidney involvement can cause jaundice and renal failure, hence the name Weil’s disease. This makes fever the best-supported statement because fever is a consistent, early clinical feature of the illness. It is not primarily a skin infection, it is not transmitted by mosquitoes, and it is not caused by Vibrio cholerae (the cholera bacterium).
