Your Home is Still a Germ Haven After You Recover—Here’s How to Disinfect
Even after you’ve kicked that cold or flu, viruses can linger on surfaces, potentially leading to reinfection.
- Flu germs can survive for up to 48 hours on surfaces.
- RSV has a shorter lifespan, lasting about 6 to 12 hours outside the body.
- Regular cleaning with diluted bleach or antiviral products is key.
- Don’t forget to disinfect frequently touched items like phones and remotes.
You’ve finally conquered the flu or a nasty winter virus, but your house may still be teeming with germs. Thorough cleaning is essential to reduce the risk of getting sick again. It’s a surprisingly common scenario, and understanding how long viruses stick around is the first step to a truly germ-free recovery.
Amanda Joy, specializing in urgent care and emergency medicine at MedStar Health, emphasizes the importance of identifying the specific illness circulating in your household. “The first thing that we need to remember is how long each virus or bacteria can last on particular surfaces. That will guide you in how you clean and disinfect your house,” Joy said.
How Long Do Germs Really Linger?
The persistence of germs varies significantly. Flu-related germs typically hang around for 24 to 48 hours, depending on the surface. RSV, a common respiratory virus, has a “very short life” outside of the body, lasting approximately six to 12 hours. Cold viruses and COVID-19 can persist on surfaces for a few hours to a few days.
To effectively disinfect your home, Joy recommends cleaning all hard surfaces and frequently touched items with a diluted bleach solution or a commercially available cleaner. A simple solution can be made by mixing one tablespoon of bleach with warm water.
While bleach is effective, Joy also suggests using Lysol products, some of which contain chemicals designed to neutralize viruses. “If you do your standard wipe downs a couple times throughout the virus — if you do it every day, that’s even better — that should be adequate to keep that from spreading,” Joy said.
Protecting Your Family, Especially Children
Families with sick children should pay extra attention to areas where their child spends time, wiping down those surfaces nightly. Toys, tablets, and remote controls are prime suspects for harboring germs and should be cleaned regularly.
Once you are fever-free for 24 hours without medication, it’s time to tackle laundry. Wash bedding and clothes in hot water with detergent to eliminate any remaining viruses or bacteria. “The hot water is important to kill the viruses,” Joy said. “Any detergent should work.”
Don’t Forget These Often-Overlooked Spots
One item Joy strongly recommends cleaning that often gets missed is your cellphone. Most people spend considerable time on their devices while sick, unknowingly transferring bacteria to a hard surface. Once healthy, wipe down your phone, and don’t forget to clean the case as well. “That’s something that typically travels around with you and can cause more of a spread of infection,” Joy said.
If you’ve had a bacterial infection like strep throat, Joy advises replacing your toothbrush after 72 hours of antibiotic treatment to minimize the risk of reinfection.
In cases of vomiting, such as with Norovirus, Joy recommends disinfecting everything you’ve touched, including hairbrushes and combs, due to the virus’s high contagiousness and longevity.
Finally, Joy stresses the importance of staying up-to-date on preventive vaccinations, such as the seasonal flu shot. Other preventative measures include proper hand washing and covering your mouth and nose when coughing or sneezing to prevent the “aerosolization of viruses into the environment.”
