CDC guidelines standard precautions prevent the spread of infectios from all except?

CDC guidelines for standard precautions are designed to prevent the spread of infections through practices such as hand hygiene, the use of personal protective equipment, and safe handling of potentially contaminated materials. However, these precautions may not fully prevent the spread of infections transmitted through airborne routes, such as tuberculosis or COVID-19, which require additional measures like respiratory protection and isolation. Therefore, while standard precautions are effective for many transmission routes, they do not entirely address airborne pathogens.
