Transmission similarities of HFMD to cholera and TB

Steps:

• Identify HFMD transmissions from notes: fecal contamination in water (like cholera) and pathogen droplets (like TB).
• Recall cholera spreads via fecal-oral route in contaminated water; TB via airborne droplets.
• Confirm HFMD matches cholera in water ingestion and TB in droplet ingestion.
• Rule out malaria, which uses mosquito bites, unlike HFMD methods.

Why B is correct:

• HFMD shares fecal-oral transmission with cholera (contaminated water) and droplet transmission with TB, per standard epidemiological definitions of these routes.

Why the others are wrong:

• A: Statement is factually true for bacterial Lyme but ignores required comparison to malaria or TB.
• C: HFMD pathogen (virus) lacks cells and is not prokaryotic; only TB's bacterial cells are.
• D: Chlorination targets waterborne HFMD but not airborne TB transmission.

Final answer: B
