Keeping the spread of infections from sick patients under control, also known as source control, is essential in order to prevent transmission to contacts who are not protected. When a patient is identified as a carrier of bacteria that exhibits resistance to antibiotics, virulence traits, and/or epidemic potential, isolation precautions are used in addition to routine precautions. In situations when the viral and/or bacterial condition of a patient is unclear, it is imperative that all guidelines for hand cleanliness and conventional precautions be adhered to in their entirety. As a result, it is essential for modern infection control to take into account the many modes of transmission, the importance of personal protective equipment, and the importance of maintaining proper hygiene habits. It is necessary to take isolation precautions against airborne, droplet, and/or contact cross-contamination routes when dealing with particular microorganisms. When it comes to isolation precautions, contact precautions are the most commonly recommended since they reduce the likelihood of contamination from germs that are associated with cutaneous or gastrointestinal diseases, as well as the transmission of bacteria that are resistant to several antibiotic prescriptions.
