Which action helps prevent TB transmission at home?

• A. Remain in same room with others
• B. Share utensils with family
• C. Wash hands after coughing
• D. Ignore cough etiquette

Answer: (C)

TB spreads mainly through tiny airborne particles released when someone with active TB coughs, sneezes, or talks. Reducing the amount of infectious particles in the home air and limiting how others come into contact with contaminated surfaces are both important parts of prevention. Washing hands after coughing helps because it lowers the chance of transferring bacteria from hands to surfaces or directly to the face, which can reduce secondary transmission through contact routes. In a home setting, this simple hygiene step complements other measures like coughing into a tissue or elbow and ensuring good ventilation to dilute and remove infectious particles from the air. Remaining in the same room with others without any precautions keeps everyone exposed to the airborne particles. Sharing utensils isn’t a reliable transmission route for TB, and ignoring cough etiquette directly increases risk. So, washing hands after coughing is the most protective choice among these options.
