20 Things You're Most Likely to Catch Coronavirus From

You won't believe where virus matter is hiding. 

The coronavirus responsible for the disease COVID-19 can remain intact on surfaces for anywhere up to 72 hours, according to a study conducted by US researchers—and it's also been confirmed to be airborne. To help you avoid the danger we asked doctors to help us identify these hotbeds of germs. You may not be able to totally avoid touching some of these items and surfaces, but being aware of them can keep your hands clean and yourself healthy. Read on and touch wisely.


Hand Sanitizer Pumps

"We tend to associate Purell with being germ-free, but did you know that the hand sanitizer pumps themselves are some of the germiest surfaces?" says J.D. Zipkin, MD, MA, FAAP, FACP, of Northwell Health-GoHealth Urgent Care. "The good news is that the contents tend to kill most germs you just picked up, but always be wary of using a container to find it's empty. Your hands are likely covered in germs."

The Rx: Zipkin says that his practice has switched to hands-free, motion-activated pumps for that reason. If you share hand sanitizer with other people, like in the office or a busy house, it might be a good idea to do the same.


Elevator Buttons

"Everyone deposits their germs on the small concentrated surface of an elevator button," says Zipkin. In fact, one study at the University of Arizona found that elevator buttons contain 40 times the bacteria of a public toilet seat.

The Rx: "Curl your finger and push elevator buttons with the back of a knuckle to reduce the spread of germs from your fingertips to your face," advises Zipkin.

OK, so you can't avoid touching these. Your hands might even be on a keyboard all day, after touching other items around the office and house, eating meals and using the restroom. But when's the last time you sanitized it? "A shared keyboard and mouse at work are full of germs, and it's tough to effectively clean every surface," says Zipkin.

The Rx: Keep antibacterial wipes close by, and wipe down your keyboard regularly. 



Cell Phones

"Believe it or not, your cell phone is one of the dirtiest things you touch—and you touch it often," says Dr. Christopher Dietz, DO, area medical director of MedExpress Urgent Care. "A dirty cell phone, especially during cold and flu season, can negatively impact your health and spread germs that cause illness. Even though we take our phones everywhere from the bathroom to the dining room table, we rarely remember to sanitize them. Every time we set our phones down on a surface, whether it's the meat counter in the grocery store or the booth at your favorite restaurant, it can pick up bacteria that can then be transferred to your hands and then possibly into your mouth or nose—and into your body."

The Rx: "I know some of my patients find it hard to put down their cell phone, even for a moment, but as a healthcare professional, I recommend leaving your cell phone behind when you head to the bathroom," says Dietz. "When you're cooking dinner or packing your lunch, put your cell phone away so that you're not tempted to pick it up in the middle of your recipe – or, at least remember to wash your hands right after you send that text or make a call."

And clean your phone regularly. "I recommend sanitizing your phone every day – and possibly more than once a day during cold and flu season, when germs and bacteria are spreading more quickly," says Dietz. "I always recommend that my patients keep antibacterial wipes within reach in the car, purse or desk drawers, so easy and frequent wipe-downs are possible."


The Gas Station Pump

"In addition to your cell phone, I always remind my patients that germs can lurk in unsuspecting places when we're out and about," says Dietz. "Think about things you touch all the time – the pump at the gas station, the pen at the bank, shopping cart handles – and then think about how many other people touch those same things day after day. Unfortunately, these surfaces don't get sanitized nearly enough. Luckily, we can take matters into our own hands with a few healthy habits."

The Rx: "Always keep a packet of on-the-go antibacterial wipes in your purse, bag or car, and wipe down the shopping cart handle or gas station pump before use," says Dietz. "I also keep an extra pen handy, so I don't have to use the communal one at the bank. Always wash your hands when you return home from running errands. You'll be amazed at how quickly these little habits become part of your daily routine."


Popular Items At The Office

"Known germy surfaces in an office space can include door knobs, elevator buttons, the shared computer mouse, sink handles and more," says Kelsey Burger, PA-C, of Hartford Health-GoHealth Urgent Care.  

The Rx: "If you're not able to always wipe down these surfaces, then you need to make sure you have access to soap and water/hand sanitizer afterwards," says Burger. "Another good tip is to always carry a small portable hand sanitizer during flu season."

"Menus in a restaurant are some of the dirtiest items in any eating establishment!" says Christina L. Belitsky, MS, RPA-C, advanced practitioner lead with Northwell. In fact, they can have 100 times the bacterial of a toilet seat: Researchers at the University of Arizona found an average of 185,000 bacteria on menus in a random sampling of restaurants in three states.

The Rx: "Carry around some hand sanitizer to fight these pesky germs," says Belitsky. Never let a menu touch your plate or silverware, and wash your hands or use hand sanitizer after you order.

Belitsky says that frequently touched turnstiles can be a magnet for germs. In 2015, researchers from Weill Cornell Medical College swabbed surfaces in and around the New York City subway; they found 27 percent of those surfaces contained antibiotic-resistant bacteria.

The Rx: Push through a turnstile without using your hands, or carry hand sanitizer and squeeze some out when you're on the other side.


Electronic Pens

The electronic pens near keypads at banks and checkout counters can also be a hotbed for germs, says Belitsky. If dozens or hundreds of people used that pen since it was last cleaned, it's like you're shaking hands with all of them.

The Rx: Carry a pen with you, and use the non-writing end to punch keypad keys and provide an electronic signature.


Your Kitchen Sponge

"Contrary to public perception, the germiest place in your house is in the kitchen, not your bathroom," says Adam Splaver, MD, a cardiologist based in South Florida. "You're going to love the irony. It's your sponge — the one you use to clean your kitchen." In fact, a study by the Public Health and Safety Organization found coliform bacteria (which could indicate fecal contamination) on more than 75% of kitchen dish sponges, compared to only 9% of bathroom handles. 

The Rx: Sanitize your sponges once a week by saturating them with water and putting them in the microwave on high for 1 minute (for scrub sponges) to 2 minutes (cellulose sponges).

The Bathroom Sink

"The toilet seat is not the germiest place in the bathroom. It's the sink," says Splaver, who notes its dampness is an ideal breeding ground for germs. According to the PHSO study, the bathroom faucet handle is the sixth-germiest site in the average house; the toilet doesn't even make the top 10.

The Rx: "It is essential to wash your hands after using the bathroom," says Splaver. Make sure you're using soap, and wash for 20 seconds — about the length of time it takes to sing "Happy Birthday" twice.


Air Dryers

In public restrooms, "It's essential to avoid the air dryers, which can be loaded with bacteria," says Splaver. According to a study by the University of Connecticut and Quinnipiac University, petri dishes exposed to hot air from a bathroom hand dryer for 30 seconds grew up to 254 colonies of bacteria. That's because air hand dryers seem to suck in bacteria from washroom air.

The Rx: "Choose paper towels to dry your hands," says Splaver. 


Your Toothbrush

If you leave it near the toilet, that is. Splaver says you should avoid storing your toothbrush near the commode to avoid the airborne transfer of germs.

The Rx: Store your toothbrush on your bathroom counter, in a far corner away from the toilet. And replace it regularly: the American Dental Association advises every three to four months, or sooner if the bristles become frayed.


This Type Of Soap

"Use antibacterial soaps, but sparingly, because they can promote bacterial resistance," says Splaver.

The Rx: The FDA says that regular soap and water is just fine for getting rid of germs on your hands and preventing illness.


Other People's Towels And Razors


"There are a lot of skin infections out there that are driven by bacteria that are more aggressive and resistant to antibiotics, such as MRSA," says Seuli Brill, MD, associate professor of clinical medicine at Ohio State University Wexner Medical Center. "Some other potential infections include impetigo, cellulitis, folliculitis and abscesses. These infections can be spread through towels, washcloths, razors and soap bars." 

The Rx: "Don't allow anything that touches your skin to touch the skin of others unless it's been laundered or cleaned," advises Brill. "Change or wash towels and washcloths every few days, allow soap bars to dry between uses and don't share razors. Use paper towels instead of cloth in guest bathrooms."


Someone Else's Drink

"If you don't know the person, you probably don't want to share a drink with them," says Brill.  "Viruses can spread via drink, specifically mononucleosis and respiratory viruses like the common cold."

The Rx: If someone offers you a sip from their cup or straw, it's OK to pass — that just might help you skip a cold or flu too.


Your Gym's Yoga Mat

Here's the opposite of namaste—exercise mats at your gym or yoga studio can be breeding grounds for bacteria; they're made from porous plastic, and germs can linger on them from hours to days. 

The Rx: "It's a good idea to bring your own yoga/exercise mat to workouts," says Brill. "If that isn't possible, make sure to wipe down surfaces before and after workouts to reduce risk of transmitting harmful bacteria." 


Your Uber's Door Handle

Public transportation has long been a hotbed of germs. In fact, one study found that people who commute to work were six-and-a-half times more likely to come down with acute respiratory infections (a.k.a. bad colds). Yeral Patel, MD, a functional medicine physician in Newport Beach, California, reminds us that rideshares are public transport, too: The door handle of your Lyft or Uber rideshare car can harbor germs.

The Rx: Carry alcohol-based hand sanitizer and apply it liberally once you reach your destination.

Shopping Cart Handles

One study found that more than half the shopping carts at an average grocery store had disease-causing bacteria on their handles, including E. coli, says Mitra Shir, MSc, RHN, a registered holistic nutritionist in Vancouver. 

The Rx: If your grocery store doesn't have antibacterial wipes near the carts, bring your own. Wipe down the handle and let it try for 20 seconds before touching it.


The Public Restroom Floor

Of course, you're thinking. Oh really? Charles Gerba, a microbiologist at the University of Arizona, has found that one-third of women's purses contain fecal bacteria, likely from being placed on the floor of public restrooms. If you come home and put your purse on your kitchen table or couch, you're welcoming those germs into the family.

The Rx: When you're using a public washroom, hang your purse on a hook or keep it in your lap, never on the floor of a stall. And when you're done, wash your hands. With soap. For 20 seconds. And don't use the air dryer.
