Hotel rooms may look sparkling clean when you first arrive - but surprising levels of bacteria and viruses can be lurking in overlooked places.
Beyond the usual suspects such as sinks and toilets, common "touchpoints" like remotes and light switches are also crawling with germs, studies say.
Hotel rooms had up to 10 times more bacteria - including fecal strains - than are allowed in hospitals, a University of Houston study found.

The staff at hotels often spend just 30 minutes tidying and cleaning each room. They may skip decorative items entirely, Enza Laterrenia, head of housekeeping at Canne Bianche Lifestyle Hotel in Italy, told Travel & Leisure.
Here's a list of spots that can be teeming with germs, experts warn - and the steps you should take as soon as you arrive in your hotel room.
"Having worked in hotels, the first thing I fling off to a far corner of the room are decorative pillows and any decorative runner that goes along the foot of the bed," Maria Diego, a San Diego, California-based travel adviser, told the travel magazine.
"These never get washed."

Duvet covers can also be a collecting place for germs.
"Most hotels do not wash the big duvet. They only wash the sheets," a former hotel staffer noted on Reddit last year.
Diego said she is also cautious about switches, remote controls, phones and other major touchpoints.
Los Angeles travel adviser Rani Cheema said hotel room phones disgust her the most.
"I am grossed out by the receiver," Cheema said. "No one's cleaning that."
HOTELS CAN NO LONGER HIDE THIS ONE THING FROM TRAVELERS
Carpets are another culprit.
Many high-end hotels are now swapping them out for flooring or area rugs, according to Cheema.
Hotel bathrooms are even dirtier than airplanes, studies have found - especially the countertops.
But the tub is also infested with germs, harboring up to 40 times more bacteria than a toilet seat, according to a 2023 investigation by WaterFilterGuru.com.
"I also won't take a bath in a hotel unless it's a super-luxe five-star hotel, and only if it's a non-jet bathtub," Diego said.

Jetted tubs can harbor more bacteria and aren't always disinfected fully, according to experts.
Ceiling fans, curtain rods, shower heads and other such spots are often neglected, according to Laterrenia of Canne Bianche Lifestyle Hotel.
LaDell Carter, founder of Maryland-based Royal Expression Travels, said she looks out for other red flags.

"When I enter a room and notice a dusty charging port next to the bed or a bedside lamp caked in residue, that tells me the basics may have been done, but the details were missed," Carter told Fox News Digital.
Housekeeping staff have been found to wipe down glassware between guests' stays - not replace it, according to reports.
"Personally, I never use mugs or glasses in the room without rinsing them out first," Carter said.
"I usually boil water in the kettle and give each item a thorough rinse."
"It's not about fear, it's about good habits," she added.
The ice bucket could be the next breeding ground.
During one norovirus outbreak at a hotel, guests vomited in ice buckets, contributing to the spread, Brian Labus, an associate professor of epidemiology at the University of Nevada Las Vegas, told Travel and Leisure last year.

Ice buckets should have a liner, experts say.
Otherwise, consider packing your own drinkware and a small cooler with ice.
If anything feels "off," alert the front desk staff, Carter recommended.
The staff can have the room cleaned again or move you to another room.
