Which of the following is an important factor in selecting disinfectants?

Selecting disinfectants is a critical aspect of infection control, particularly for occupational settings where there is a risk of exposure to bloodborne pathogens like HIV (Human Immunodeficiency Virus) and HBV (Hepatitis B Virus). Effectiveness against these specific pathogens is paramount because it ensures that the disinfectant used will effectively reduce or eliminate the risk of transmission of these viruses from contaminated surfaces.

A disinfectant that has been proven effective against HIV and HBV has passed specific efficacy testing indicating that it can inactivate these viruses on surfaces, thus protecting workers and clients from potential infections. This criterion is supported by guidelines and regulations set forth by regulatory agencies like the Centers for Disease Control and Prevention (CDC) and the Environmental Protection Agency (EPA), which provide lists of effective disinfectants for use against bloodborne pathogens.

In contrast, while brand reputation, packaging design, and popularity among staff can have their importance in certain contexts, they do not directly impact the disinfectant's ability to perform its primary function: effectively killing or inactivating harmful pathogens. The priority should always be the proven efficacy of a disinfectant against specific bloodborne pathogens.
