Verifying disease transmission and characteristics

Steps:

• Identify cholera as bacterial infection from Vibrio cholerae via contaminated water.
• Confirm HIV/AIDS transmission routes include breast milk from infected mothers.
• Recognize global malaria eradication programs led by WHO since 1955.
• Classify measles as a viral infection from paramyxovirus.

Why A is correct:

• Each statement matches established epidemiology: cholera bacterium, HIV breast milk transmission, malaria eradication efforts, measles virus.

Why the others are wrong:

• B: Cholera transmission is fecal-oral via water, not "eaten raw"; malaria eradication ongoing, not unsuccessful; measles blindness rare, not usual.
• C: HIV not vector-borne; malaria caused by Plasmodium parasite, mosquito is vector; incomplete for measles.
• D: Measles has effective MMR vaccine, contrary to "no effective vaccination."

Final answer: A
