The COVID-19 pandemic has highlighted the importance of cleanliness and hygiene in preventing the spread of diseases. However, many people still confuse these two terms, leading to inadequate practices.

Understanding the factors that affect the survival of pathogens on surfaces is crucial in developing effective cleaning protocols.
