MANILA, Philippines鈥擶orldwide, people spend most of their time using their mobile phones鈥攕crolling through social media, watching videos, or communicating online. However, most fail to realize that mobile phones collect a lot of germs each day鈥攁nd could become ten times dirtier than a toilet seat.

Social media management firm Hootsuite and creative agency We Are Social found that in the Philippines, 98.8 percent of internet users aged 16 to 64 own mobile phones. Around 98.8 percent own smartphones, while 11.9 percent own feature phones.

On average, Filipinos spend 5 hours and 47 minutes each day using their mobile phones to surf the internet. That translates to up to 6 hours of touching mobile phones and bringing them everywhere.

Studies found that spending the same鈥攐r more鈥攁mount of time touching mobile phones and bringing them to potentially bacteria-prone places increase the risk of transferring germs, bacteria, and pathogens to the devices.

Mobile phones are covered in bacteria

A study by microbiologists at the University of Arizona found that mobile phones鈥攃onsidering the average amount of time a person spends each day handling those devices鈥攎ake a breeding ground for germs and bacteria.

In fact, microbiologists stated that mobile phones carry ten times more bacteria than toilet seats鈥攚hich, they explained, naturally get cleaned frequently since most people associate bathrooms with germs.

Among the most common microorganisms found in mobile phones are various bacteria, fungi, and viruses. A separate study published in 2017 showed that, on average, there are at least 17,000 bacterial gene copies on a mobile phone.

A previous report claimed that mobile phones carry more bacteria per square inch than other high-touch surfaces or places that are the common breeding grounds for bacteria.

Compared to mobile phones, which the article said could carry over 25,000 bacteria per square inch, a public toilet seat could only carry 1,201 bacteria per square inch. Other surfaces such as kitchen counters (1,736), pet food dish (2,110), and a doorknob (8,643) have lesser bacteria per square inch than mobile phones.

But how did this happen? How did those microorganisms end up in mobile phones?

According to US-based Northwestern Medicine Regional Medical Group, mobile phones pick up dirt, oil, and bacteria that people have on their skin. Every time people use their mobile phones, they transfer tiny microorganisms from their hands and fingers to their phone鈥檚 surface.

Mobile phones make you sick

Studies noted that while many types of bacteria commonly found in mobile phones are mostly harmless, some harmful pathogens may be transferred onto the surface of mobile phones and spread from person to person.

According to the British Columbia Center for Disease Control, 80 percent of all infections are transmitted by hand. As a result, bacteria are easily transferred to mobile devices.

When people hold their dirty phones to their face, the bacteria and other microorganisms enter the skin鈥檚 pores and cause minor skin breakouts. In some cases, dirty mobile phones could cause more serious conditions from harmful bacteria such as:

• Streptococcus鈥攁 type of bacteria that causes strep infections
• Methicillin-resistant Staphylococcus aureus (MRSA)鈥攁 type of bacteria resistant to several widely used antibiotics, making it difficult to treat
• E. coli鈥攂acteria found in the environment, food, and intestines of people and animals
• Coliform鈥攂acteria that are always present in the digestive tracts of animals, including humans, and are found in their wastes
• Coagulase Negative Staphylococci (CoNS)鈥攁 type of staph bacteria that commonly live on a person鈥檚 skin
• Mold鈥攁 type of fungus that forms and spreads on various kinds of damp or decaying organic matter
• Yeast, including various subspecies/genera of candida (parasitic fungi).

鈥淎lthough the infectious dose of pathogens varies, it is still important that they don鈥檛 enter your system,鈥� said US-based manufacturer Sani Professional.

鈥淎lso, once a person is infected, pathogens can spread from one person to another by sharing a phone. For instance, if a person was sick and coughed onto their phone while speaking on it, then handed it to someone else to use, the second person could be exposed,鈥� it added.

Experts from the Northwestern Medicine Regional Medical Group warned that people with weaker immune systems鈥攗nlike healthy individuals鈥攁re more vulnerable to common bacteria that live on mobile phones.

Clean, sanitize, disinfect

To reduce the amount of microorganisms鈥攕uch as bacteria, viruses, or pathogens鈥攆ound on mobile phones, experts recommend applying different levels of cleaning on the devices. These, according to company Sani Professional, include:

• cleaning鈥攖o remove visible soil and debris from surfaces;
• sanitizing鈥攖o lessen the presence of any bacteria, virus, and fungi from the mobile phone鈥檚 surface
• disinfecting鈥攖o eliminate pathogens and disease-causing microorganisms

Amid the COVID-19 outbreak, the US Centers for Disease Control and Prevention (CDC) released a reminder on how to clean and disinfect electronic devices like mobile phones and touch screens.

The US CDC noted that mobile phone users should follow manufacturer鈥檚 instructions for cleaning and disinfecting. However, if there is no guidance, it suggested using alcohol-based wipes or sprays containing at least 70 percent alcohol鈥攁nd then drying the surface thoroughly.

Other experts recommended the following steps when cleaning and disinfecting mobile phones:

• Unplug or turn off the device before cleaning or disinfecting.
• Use a soft, lint-free, waterproof, and dust-proof wipe, such as a camera lens wipe, to gently wipe the surface of the device.
• Lightly damp washcloth with soap and water.
• Avoid spraying cleaners directly onto the device.
• Avoid aerosol sprays and cleaning solutions that may contain bleach or abrasives.
• Prevent liquids and moisture from reaching and entering any openings on the device.

Dr. Dan Allan from the Cleveland Clinic suggested wiping down mobile phones daily or more if it may have been exposed to contamination.

鈥淚n addition to this, he recommends routinely cleaning all surfaces and objects that you come into contact with throughout the day 鈥� counters, doorknobs, refrigerator handles, remote controls, your computer keyboard, and even your keys,鈥� the Cleveland Clinic said, citing Allan.

He also recommended starting with proper hand hygiene to prevent the spread of germs.

鈥淗and washing is always better than hand sanitizer 鈥� certain infections (like norovirus) are not killed by hand sanitizer and must be washed off,鈥� he continued.

Aside from cleaning and disinfecting mobile phones and other sanitary measures, experts recommended restricting the use of mobile phones in areas where it can pick up microorganisms, such as:

• kitchens (commercial and residential)
• bathrooms
• dining tables
• doctor鈥檚 offices
