Sanitize Your Nose: Help Protect Yourself and Others from Infection

(NewsUSA) – Most people know that practicing good hand hygiene, such as washing or sanitizing the hands regularly, can help reduce the risk of infection. However, many are overlooking a key culprit in the spread of germs: the nose. With hand hygiene, sanitizing the nose is a simple step that can help prevent the spread of germs and enhance overall health. The moist, hairy skin inside the nostrils is the perfect environment for potentially dangerous germs to grow and multiply. The nose is like a revolving door for germs, allowing them to enter and exit the body. Sneezing, coughing, or touching the nose can spread infectious germs to others. In turn, touching the nose – which a person does more than 100 times a day on average – can also spread germs from the hand to the nose. However, sanitizing the nose interrupts the cycle of contamination between the hands and nose and can help reduce the spread of germs that cause infection. Sanitizing the nose, also referred to as nasal decolonization, is a proven infection prevention measure that has been practiced by healthcare professionals for decades.

A 2020 American Journal of Infection Control (AJIC) study shows a decrease in infections to zero when an alcohol-based nasal antiseptic is added to existing infection prevention protocols. Due to the extensive research showing that sanitizing the nose significantly reduces infection rates, the Centers for Disease Control and Prevention (CDC) recommends that all hospitals include nasal decolonization of patients in certain situations in which they are at a higher risk of infection. Despite being an established health care practice, only 3 out of 10 Americans understand that sanitizing the nose helps reduce infection risk, according to a recent survey by YouGov.*Given the positive impact that hospitals have seen with sanitizing patients’ noses, it is time the general public adopts this practice. Health care experts advise that sanitizing the nose is a simple and effective way to protect oneself and others from infection and be part of daily hygiene practices. It is important to note that not all nasal products are formulated to kill germs in the nose. Many over-the-counter nasal hygiene products can help clean but do not sanitize the nose.

These include nasal sprays to help alleviate dryness, congestion, or inflammation from cold, flu, or allergies; nasal rinse products that flush out mucus and debris from the nose; and steam or humidifiers that help loosen mucus in the nose. There are three solutions currently available that are proven to kill germs in the nose and are clinically supported with hospital studies: alcohol-based nasal antiseptic (Nozin), povidone-iodine antiseptic (various brands, including 3M) and mupirocin antibiotic (various brands, including Bactroban).

The figures have been weighted and are representative of all US adults (aged 18+). YouGov conducted the national survey on behalf of Nozin.
