Hey there, phone users! Let's talk about a topic that might make you squirm a bit: the dirty truth about your beloved devices. Your phone, that trusty companion, could be a microbial hotspot!
We all know phones are everywhere. They're our constant companions, from the moment we wake up to the second we drift off to sleep. But here's where it gets controversial: despite their ubiquity, we often overlook the potential health risks they pose.
The Microbial Invasion
Imagine this: a 2019 survey revealed that most folks in the UK use their phones while doing their business in the bathroom. Gross, right? Well, it gets worse. Studies show our phones are dirtier than toilet seats! Yikes!
We hand our phones to kids (who, let's face it, aren't exactly hygiene experts). We eat with them, placing them on various surfaces, dirty or otherwise. All these actions transfer microbes and food deposits onto our phones.
A Touchy Subject
We touch our phones hundreds, maybe even thousands of times a day. Yet, while we wash our hands after certain activities, like using the bathroom or cooking, we often neglect to do the same after handling our phones. This is a problem because our hands pick up bacteria and viruses, and so do our phones.
The Microbial Menagerie
Studies have shown that phones can be contaminated with a variety of potentially pathogenic bacteria. These include E. coli, which causes diarrhoea and originates from human faeces, and Staphylococcus, which can infect the skin. There's also Actinobacteria, which can lead to tuberculosis and diphtheria, and Citrobacter, a culprit behind painful urinary tract infections. Enterococcus, known for causing meningitis, has also been found on phones, along with Klebsiella, Micrococcus, Proteus, Pseudomonas, and Streptococcus, all of which can cause serious health issues.
Antibiotic Resistance and Beyond
Research reveals that many pathogens on phones are antibiotic-resistant, meaning conventional drugs won't work. This is concerning because these bacteria can cause skin, gut, and respiratory infections, some of which can be life-threatening.
Viruses and Plastic
Phones, with their plastic surfaces, can harbour and transmit viruses. The common cold virus, for instance, can survive on hard plastic for up to a week. COVID-19, rotavirus, influenza, and norovirus can also persist on these surfaces for several days, maintaining their ability to infect.
The COVID Effect
Since the COVID pandemic began, the US Centers for Disease Control and Prevention has issued guidelines for cleaning and disinfecting mobile phones. Phones, along with other high-touch surfaces like door handles and ATMs, are considered potential reservoirs of infection.
Hospitals and Schools
There's growing concern about the role mobile phones play in spreading infectious microbes in healthcare settings and schools. It's a serious issue that demands our attention.
Time to Clean Up
It's clear that regular phone cleaning is a must. The US Federal Communications Commission recommends daily sanitation, especially during the ongoing COVID-19 pandemic, as the virus can survive on hard plastic surfaces for days.
Use alcohol-based wipes or sprays containing at least 70% alcohol to disinfect your phone's casing and touchscreen. Do this daily if possible. Avoid spraying sanitisers directly on the phone, keep liquids away from connection points, and steer clear of bleach and abrasive cleaners. Always wash your hands thoroughly after cleaning.
Handle with Care
Consider how you handle your phone to avoid germ colonisation. Keep it in your pocket or bag when out and about, and use disposable paper lists instead of constantly checking your phone. Wash your hands with soap and water or use alcohol-based hand sanitiser before touching your phone.
Prevention is Key
Don't share your phone if you're infected or if it hasn't been sanitised. If kids play with your phone, sanitise it immediately after. Get into the habit of putting your phone away when not in use and then sanitising or washing your hands. Occasionally sanitise your phone charger too.
So, there you have it! A dirty truth revealed. Are you ready to step up your phone hygiene game? Remember, a little extra care can go a long way in keeping you and those around you healthy.
