Which activity is considered safe for a person receiving treatment for tuberculosis (TB)?

Sharing a TV remote is considered safe for a person receiving treatment for tuberculosis (TB) because TB is primarily spread through airborne particles when an infected person coughs, sneezes, or talks. In contrast, sharing a common object like a remote control does not facilitate the transmission of TB, as long as the individual with TB is adhering to their treatment plan and taking necessary precautions to avoid spreading the bacteria through the air.

The other activities listed are associated with higher risks of transmission. Sharing food or drink is risky since it can lead to saliva exchange, which might facilitate the spread of TB. Spending time with pets may increase anxiety about potential infection; although TB is not typically transmitted from animals to humans, caution is still advisable. Sharing needles poses a significant danger, as it could lead to the transmission of infections, including potentially TB in severe cases, alongside other bloodborne pathogens. Therefore, among the options provided, sharing a TV remote stands out as the safest activity.
