Final answer:
Two non-BCG methods for preventing TB are isolation, to avoid spreading the disease through airborne particles, and hand hygiene to reduce transmission through contact with contaminated surfaces.
Step-by-step explanation:
The question asks for non-BCG methods of TB (tuberculosis) prevention. Two such non-BCG TB prevention methods are isolation and hand hygiene. Isolation involves keeping those who have active tuberculosis away from those who are not infected, which helps prevent the spread through airborne particles when coughing or sneezing.
Hand hygiene is a preventive measure that reduces the chance of transmission of pathogens, including TB, through contact with contaminated surfaces.
