COVID On Your Cell Phone

COVID On Your Cell PhoneAmid the chaos of the COVID-19 lock-down one of your only allies in the social distancing campaign is your cell phone. Right? After all, everybody is attached to their mobile phone. In fact, research has shown that millennials check their phones 150 times a day (PDF). Why do we check our cell phones so much?

Researchers from the University of Illinois found in a recent study that 37% of women and 30% of men walking down the street have a smartphone in their hand. The UofI researchers Laura Schaposnik and James Unwin paper The Phone Walkers: A study of human dependence on inactive mobile devices propose four plausible reasons that pedestrians practice this behavior.

Appeasement – The first proposal is that we need immediate access to our phones now because so much of our social lives exist on the phone. In particular, research suggests that people in romantic relationships expect to be texted back within five minutes. We keep our phones out to appease partners.

anxiety if separated from mobile phonesAnxiety – The researcher’s next hypothesis was that we might be psychologically dependent on these phones to the point that we have anxiety if we’re separated from them. The researchers write. “… the simple manipulation of the object could lead to a corresponding decrease in tension or anxiety ….”

Safety – Personal safety is another distinct possibility. Research has found that technology gives young people confidence when facing the potential dangers of crime in a public place. The UofI team says we “..may hold their phones both for personal reassurance against perceived threats and as a visible warning sign to potential assailants.

peacock effectThe peacock effect – We might want to impress a possible partner with our fancy phones. The researchers compared the phenomenon to “displays of affluence by wearing designer fashion clothes or jewelry … to enhance or affirm a person’s social standing and to attract a suitable mate.

We are addicted to our cell phones so what? I have covered the germiness of mobiles on the Bach Seat before. But in the wake of recent events, I checked on current thinking and found that COVID-19 is probably on your mobile. German researchers reported (PDF) in the Journal of Hospital Infection that Coronaviruses can live on inanimate surfaces like metal, glass, or plastic, and remain infectious “from 2 hours up to 9 days.

Coronaviruses can live on surfaces like metal, glass, or plastic, and remain infectious "from 2 hours up to 9 days."Lead researcher Günter Kampf, M.D., an associated professor at the University of Greifswald, reported that a good strategy for surface disinfection is with a solution that contains 0.1% sodium hypochlorite or 62 to 71% ethanol. Either of these “significantly reduces coronavirus infectivity on surfaces within 1 min exposure time.

Charles Gerba, Ph.D., professor of microbiology and immunology at The University of Arizona, told Mens Health

…What we found … in office buildings is that you touch a surface with a virus on it and then you place it on your cell phone.” (A door handle, for example.) … You then go home or to another location and you touch your phone again a touch a table moving it to another location—great way to spread viruses around an office.

great way to spread viruses around an officeDr. Kampf warns,Check with the manufacturer. First, it should be effective against coronavirus … Second, not all disinfectants are compatible with the material of the smartphone surface.

Professor Gerba recommends an alcohol wipe or a microfiber cloth. “I would do it every time I have been out in public,” he says.

Your Smartphone Can Kill

Your Smartphone Can KillWe all love our smartphones. But did you know that your phone can kill you? And not only texting while driving can kill you and other people. A man in Uganda reportedly contracted Ebola from a mobile phone. Reports say he stole the smartphone from a quarantined ward of a hospital, near the site of a recent Ebola outbreak.

Next time you come down with the flu or Ebola, blame your cell phone. According to the London DailyMail, researchers have discovered there are more bacteria on the average smartphone than you will find in a toilet.

Tests at the University of Arizona by microbiologist Charles Gerba found there was up to 10 times the amount of bugs that can cause nausea, stomach problems, or even death on cell phones than are present in a lavatory.

The expert explains that germs are spread by phones that are often passed between people but are never cleaned which allows the germs to keep on building up. The University of Arizona researcher says the bugs get on a phone because it is so close to our hands and mouths. When somebody lets a friend or a stranger use their smartphone their bacteria easily gets on the device too.

Add to this frenzy of activity that germs thrive in warm places. Not only does your smartphone generate its own heat, but it also gets some help from your own body heat by spending time in your hands and next to your mouth.

ProGerms on your cellfessor Gerba added that because mobile devices are electronic some people are reticent about cleaning them. He says that phones are just not part of our cleaning routine whereas we should think about giving them a wipe with an antibacterial substance now and then.

In order to clean your iPhone, Apple (AAPL) says:

  1. Unplug all cables and turn off iPhone (press and hold the Sleep/Wake button, and then slide the onscreen slider).
  2. Use a soft, slightly damp, lint-free cloth. Avoid getting moisture in openings.
  3. Don’t use window cleaners, household cleaners, aerosol sprays, solvents, alcohol, ammonia, or abrasives to clean your iPhone. The front and back glass surfaces have an oleophobic coating.
  4. To remove fingerprints, simply wipe these surfaces with a soft, lint-free cloth. The ability of this coating to repel oil will diminish over time with normal usage, and rubbing the screen with an abrasive material will further diminish its effect and may scratch the glass.
