What percentage of deaths in Cardiff from 1842-48 were due to cholera outbreaks?

• A. 33%
• B. 10%
• C. 50%
• D. 25%

Answer: (A)

Cholera outbreaks were a major killer in mid-19th century towns, and in Cardiff during 1842–48 the mortality records show that about one third of deaths were caused by cholera. That places the impact at roughly 33%, illustrating how significant cholera was as a public health threat before modern sanitation and medical understanding reduced its toll. The other percentages would understate or overstate the true burden; cholera was a major, not isolated, cause of death in that period, which is why 33% is the best reflection of the data.
