Bacteria are made up of pathogens (bad germs) and non-pathogens (good germs) and are generally scattered across the home. Most surfaces in the home are covered to a certain degree with bacteria, but unlike fixed surfaces such as kitchen work surfaces and furniture, dust can move more easily around different parts of the home and therefore presents a major route for human exposure to bacterial infections.

Despite being clear evidence for microbial exposure and infection transmission within the home, there has been less research effort invested in understanding the home environment, due to difficulty of conducting detailed studies. Although the transmission routes by dust in the home environment are well known, what has not been studied is how to prevent bacterial infection at home and thereby reduce resistance.

Particularly in developing countries, such as Ghana, social inequalities mean a range of different quality and types of homes; this combined with often poor levels of domestic hygiene that is influenced by a number of economic, educational and religion factors, contributes to the spread of infectious diseases.

Understanding the hygiene practices in the household and interactions with airborne AMR bacteria will serve as a first step to designing appropriate education/information dissemination materials for various sections of the Ghanaian population as well as other low- and middle-income countries in Africa.
