I assume you mean the aims of a mask-wearing campaign or initiative, rather than a TV channel.

The primary aims of a mask-wearing campaign are to:

1. Reduce the transmission of airborne pathogens, such as viruses and bacteria.
2. Prevent the spread of infectious diseases, like COVID-19, influenza, and others.
3. Protect vulnerable individuals, such as healthcare workers, immunocompromised persons, and older adults.
4. Decrease the number of cases and hospitalizations due to respiratory illnesses.
5. Promote public health and safety.
6. Encourage personal responsibility and community solidarity.
7. Support efforts to combat pandemics
