The Germiest Places You Could Ever Touch

Here's how to protect yourself from illness at home, work and play.

Even before COVID-19, you should have been careful about your exposure to germs. Many places you go to every day are petri dishes for illness-inducing bacteria and hot zones for disease. Here from Eat This, Not That! Health are 23 places that could make you sick, as well as prevention tips from the nation's top doctors. Read on—and to ensure your health and the health of others, don't miss these Signs Your Illness is Actually Coronavirus in Disguise.


An Airplane

So many people get sick after traveling via airplane, mostly due to the close quarters, uncleaned services, and stagnant air. "During travel, you're typically in close contact with a large number of people, and you have a very limited ability to move yourself away from someone who may be sick," explains Richard Martinello, MD, a Yale Medicine infectious disease expert. Any surfaces on the aircraft—especially those oh-so-dreadful lavatories—can be heavily used, and contaminated.


How to Stay Healthy on an Airplane

First, follow your airline's rules for social distancing. Dr. Martinello also urges the importance of keeping your vaccinations up to date. If you are traveling in the fall, try to get your flu shot at least two weeks before you travel. Also, wash your hands often. "Soap and water will help to remove any soiling from your hand. Waterless, alcohol based hand rubs can be more effective than soap and water for most germs. Bring alcohol hand rubs or wipes with you so you can wash your hands when needed," he suggests. You can also use a disinfectant wipe to clean your tray. Lastly, try and keep your hands away from your eyes, nose and mouth.


Daycares and Schools

Schools and daycares can seriously compromise your health because of the close contact with others and the fact that surfaces may be contaminated with others' germs, points out Dr. Martinello. Also, lots of parents send their kids to school sick, sometimes knowingly because of a lack of childcare, infecting others.

Again, make sure you and your childrens' vaccinations are up to date. Dr. Martinello reiterates that it's best to get the flu shot before influenza starts to spread in your community. (The CDC recommends getting vaccinated against the flu before the end of October.) Make sure your child knows to wash their hands frequently, and, if allowed by the school, consider linking a portable hand sanitizer bottle to your child's lunchbox. Lastly, don't send them to school if they are sick! 


The Office

For the exact same reasons as schools and daycares, the office is the perfect place to catch something. You're in a communal workspace, sharing a bathroom, kitchen, chairs, couches—sometimes even mugs. And they're not even your family. Even with coronavirus measures in place, you need to be careful.

Again, washing your hands frequently is crucial. "Soap and water will help to remove any soiling from your hand. Bring alcohol hand rubs or wipes with you, on your desk, or in your bag so you can wash your hands when needed," he says. (Keep your keyboard clean, too.) Last but not least, stay home when sick—and this goes for everybody!  


Your Home

Sick family members are a huge threat when it comes to illness, according to Dr. Martinello. "When a family member is sick, we often have close contact with them and surfaces which they may have contaminated, such as the toilet, especially if you're responsible for caring for them," he explains.

If your family member is sick, have them stay in a separate room if possible and away from the family. "For COVID-19, the period of quarantine is 14 days from the last date of exposure because the incubation period for this virus is 2 to 14 days," says the CDC. "If they have diarrhea or vomiting, if it is possible to have a bathroom dedicated for their use, it can help to limit others from being exposed to their germs," Dr. Martinello points out.

If this is not possible, frequently clean the surfaces of the bathroom with a disinfectant following the label instructions and don't share a towel for drying hands—use a roll of disposable paper towels. Also, do not share a bar of soap — this too can become contaminated. Also, try to limit the number of persons who have direct contact with the sick family member. "If that caregiver gets sick, the chances will be better that a healthy person will be available to help them through their illness," he says. 


Your Kitchen

Raw meat and eggs, even when perfectly fresh and wholesome, may be contaminated with bacteria which can make you ill, explains Dr. Martinello. "The risk for getting sick from this made worse if you contaminate surfaces, such as the countertop and your hands, and transfer the contamination to other surfaces and foods," he explains. 


How to Stay Healthy in Your Kitchen

Always follow safe food preparation practices, instructs Dr. Martinello. This includes the following: 

  • Limit the surfaces exposed to raw meats or eggs
  • Make sure that raw meat or eggs don't splash other foods- especially those, such as lettuce, which you will not be cooking
  • Wash the utensils used for raw meats/eggs thoroughly before using them on any other foods
  • Clean the surface(s) potentially contaminated by raw meat/eggs with a disinfectant solution following the label instructions for use before allowing any other foods or clean dishes, utensils, etc. to touch those surfaces
  • To limit the spread of coronavirus, in an area away from the kitchen dispose immediately of any grocery or delivery bags.


Moldy Basements

Most of us don't think about how our basement might be impacting our health, but according to Dean Mitchell, MD, board certified allergist and immunologist, of Mitchell Medical Group, we definitely should. "Moldy basements can make a person ill," he explains. "Mold doesn't just smell bad but molds can give off mycotoxins that can cause rashes, asthma, headaches and fatigue."

The best way to eradicate mold, according to Dr. Mitchell, is by reducing humidity. You can easily do this with the help of a dehumidifier unit.


The Gym

With all the sweating going on, it should come as zero surprise that the gym is a breeding ground for germs. "The gym is a place where a lot of people get sick from not cleaning off equipment between usage," states Allen Conrad, BS, DC, CSCS of Montgomery County Chiropractic Center.

After lifting or doing cardio, Dr. Conrad urges the importance of always wiping down machines with alcohol pads or at least paper towels before and after use. "Gym attendants should wipe down all machines with an alcohol spray once an hour to help spread germs as well," he points out. 


The Mall

The mall is a great place to get all your shopping done, but it can also harbor a lot of germs. "Germs are everywhere from doors, hangers, and money," Michelle Reed, DO, MS Family Medicine points out. "Additionally, there are all those people coughing and sneezing as you walk past them."

Wash your hands—a lot. "Wash your hands before eating and after touching money," Dr. Reed urges. "Do not touch your face or nose without washing your hands."


Indoor Play Spaces

Indoor play spaces might seem like just what the doctor ordered as a great way to kill a day with your kids—especially in the winter—but according to Annette Cameron, MD, a Yale Medicine pediatrician, they are a breeding ground for germs. She notes to be incredibly wary of the ball pits and play tunnels, which are rarely cleaned. "These make you sick because children who are harboring viruses and bacteria will cough, drool, sneeze, vomit, urinate etc. on or in these places and then other healthy children will touch or mouth these objects and become sick," she points out. 


How to Stay Healthy in Indoor Play Spaces

Dr. Cameron suggests avoiding indoor play spaces during the height of flu and respiratory virus season—namely fall and winter—and altogether if possible. "If you must go wash hands or use hand sanitizer frequently," she suggests. "If you see someone visibly sick—leave!"


Public Transportation

Similar to airplanes, enclosed areas such as public transportation are other places that can compromise your health. "These make you sick because you are in an enclosed space sharing the air with potentially sick people, who if coughing or sneezing can transmit the germs through the air," Dr. Cameron explains. Most respiratory viruses can be spread through the air via droplets and many can survive for some time on inanimate objects like doorknobs, tables and other surfaces. 


How to Stay Healthy on Public Transportation

Dr. Cameron suggests avoiding public transportation as much as possible. However, if you do use it, bring along some hand sanitizer or antibacterial wipes, which you can use to wipe down your space. And wear a mask.

Most of us consider hospitals to be safe havens when it comes to our health, however, it is very much the opposite. One of the worst places for germs is actually the emergency room. "Spending a long time in a place where others may be sick and are coughing, sneezing near you will probably make you sick," Dr. Cameron points out. 


How to Stay Healthy in Hospitals

Avoid the emergency department unless it is a true emergency, suggests Dr. Cameron. "If at all possible try to go to your doctor's office instead." 


Grocery Stores

There are so many ways your grocery store can incite illness—from foods contaminated with e.coli (and juices leaking out of the package) to all the fridge handles that have been touched by germ-ridden hands. One scary study discovered 33,340 bacteria colonies per square inch—more than 1,235 times the bacteria found on the average cell phone.

Consider antibacterial wipes your best friend—and don't even think about putting your hands near your face after handling anything during your grocery shopping trip. And always wear a mask.


Cruise Ships

With all the stories in recent years about mass illnesses on cruise ships, it should come as zero surprise that the sailing the seas can have a not-so-friendly impact on your health. In fact, the CDC has an entire page devoted to "Outbreak Updates for International Cruise Ships" listing all of the illnesses reported on the vessels. There have been a total of nine outbreaks reported in 2019 alone, eight of them being norovirus, the extremely contagious food-bourne illness. 


How to Stay Healthy on Cruise Ships


It's probably a good idea to avoid hopping aboard a cruise ship. If you do go on one, the CDC recommends using proper handwashing techniques throughout your voyage, but especially after using the bathroom and before eating, avoiding any food or water that you think may be contaminated, avoiding raw or undercooked shellfish, avoiding unnecessary direct hand contact with surfaces such as public toilet room door handles, and avoiding unnecessary close contact with ill persons.


Public Bathrooms

For obvious reasons, public restrooms are full of germs. So many different diseases are carried through fecal matter, and it's very likely that little particles of poop make their way onto handles, stall walls, and are even blowing through the air. One 2018 study found that bathroom hand blowers suck up bacteria from the air and distribute them onto newly washed hands.

If you are using a public bathroom always wash your hands immediately afterwards—and use paper towels instead of the hand dryer. You also might want to consider using hand sanitizer after touching any door knobs in there as well. 


Movie Theaters

Movie theaters are one of the more unexpected places where germs tend to congregate. In 2014, ABC's 20/20 investigated movie theaters in Los Angeles and New York—and what they found was super scary. Theater seats were seriously contaminated with bacteria found in cattle and soil, and also bacteria commonly found in human feces and yeast—and it often makes its way into your food. According to The Washington Post, a whopping 85 percent of the handfuls of popcorn touched with hands inoculated with E. coli contained the bacteria, while 79 percent of the popcorn samples remaining in the tub contained E. coli transferred from the person taking a handful of popcorn from the same bowl.

Your Cell Phone

In the realm of everyday surfaces, cell phones are a bacterium's BFF. Why? We're constantly touching our phones, holding them to our mouths and setting them down on public surfaces, turning the average smartphone into a germ jitney. Skeptical? Researchers found that a dirty cell phone can contain more bacteria than a toilet seat.

Door Handles

We tend not to think about the germiness of public door handles, just because they're unavoidable. But their ubiquity is the best argument for frequent hand-washing: A recent test found the door handle on a New York City Starbucks location was 31 times germier than surfaces in the subway.

The Kitchen Sponge

The germiest item in your house is in the kitchen, not your bathroom: It's the sponge. Researchers say that kitchen sponges contain more active bacteria—including illness-causing E. coli and salmonella—than any other surface in the house. How much more? A study by the Public Health and Safety Organization found coliform bacteria (a sign of fecal contamination) on more than 75% of kitchen dish sponges, compared to only 9% of bathroom handles. 


How to Keep Your Kitchen Sponge Clean

Replace your sponges often, or sanitize them once a week in the microwave. Saturate them with water and microwave on high for one minute (for scrub sponges) or two (for cellulose sponges). 


Bathroom Sink

"Studies found that sinks are the greatest reservoir of germ colonies in restrooms, thanks in part to accumulation of water that become breeding grounds for tiny organisms," says Adam Splaver, MD, a cardiologist in Hollywood, Florida. In fact, the Public Health and Safety Organization study found that the bathroom faucet handle is the sixth-germiest site in the average house. The toilet didn't even crack the top 10.


How to Keep Your Bathroom Sink Clean

Your Car

A recent study found there are 700 strains of bacteria, on average, living in the interior of your car. The average steering wheel has about 629 units of bacteria per square centimeter. That makes it four times dirtier than a public toilet seat!

Fido's Bowl

"Ceramic and plastic dog bowls are amongst the most germ-ridden surfaces in the average home," says Richard Ross, editor of The Dog Clinic. "They often host E. Coli and salmonella, among a variety of other bacteria and viruses. Many dog owners don't realise this, and are happy to put the bowl on kitchen surfaces that are used to prepare food."
