How Long Can a Virus Live Outside the Body
The CDC said on average a person gets two to three colds per year. Most of these colds are also caught in the wintertime and spring. With cold and influenza season around its summit, it can be hard to avert catching a virus that'south going around.
Germs are everywhere this fourth dimension of year, from doorknobs to desks. If a person chooses not to wash their hands after sneezing, coughing or blowing their olfactory organ, those germs and bacteria are even more common.
Information technology'due south hard to avert touching things like doorknobs, only how long practise viruses survive outside of the body?
"Flu viruses tin survive on hard surfaces and infect some other person for 24 to 48 hours. Cold viruses don't survive as long – usually a few hours. Merely there is evidence that they can survive and be passed on for up to 24 hours." That'due south how Dr. Alison Carey, an acquaintance professor of microbiology and immunology at Drexel University, explained the health chance.
Common cold Viruses
Carey said common cold viruses typically only survive a few hours on hard surfaces, such as doorknobs and autobus poles, but tin can survive up to 24 hours. While this is truthful, it also depends on the blazon of cold virus.
Each virus is dissimilar, which means each one can survive a different length of time on surfaces. Some cold viruses might survive up-to and fifty-fifty longer than seven days on hard surfaces. Others might be gone within a few hours.
Cold viruses tin also survive on soft surfaces, such equally fabrics, but non equally long equally they would on hard surfaces.
While the cold viruses can survive for days exterior of the torso, National Health Services (NHS) said, "Their ability to cause an infection reduces chop-chop and they don't frequently survive longer than 24 hours."
That'due south non to say a person can't catch a cold virus from touching one of these surfaces.
Let's say a person coughs or sneezes into their mitt, then touches a doorknob. Gross, yes, only it also creates a brief window of likely disease spread. The virus they left on the doorknob is probable to infect someone who touches it inside the 5-ten minutes since the ill person touched it.
Cold viruses final an even shorter amount of fourth dimension on hands. According to the NHS, cold viruses just survive a short amount of time on easily with some lasting only a matter of minutes and others up to an hour.
Influenza Viruses
Much like cold viruses, flu viruses typically don't terminal longer than 24 hours on hard surfaces. Influenza viruses can just last upward to 15 minutes on soft surfaces like tissues.
These viruses also last much shorter on hands besides. After about v minutes of flu viruses being on hands, they drop to low levels, which means they likely won't infect anyone.
Flu viruses may last a brusk period of time outside of the body, merely Carey said although it doesn't final long, any surface can still harbor flu viruses long enough to infect someone. It just depends on when a person touches this surface.
If a person touches a surface minutes after a sick person does, there is a much college chance that this person tin become infected with the flu, much similar common cold viruses.
Unlike common cold viruses, according to the NHS, "Flu viruses can also survive every bit droplets in the air for several hours; low temperatures increment their survival in the air." The cold air too explains why flu viruses are much more mutual during the winter.
Stomach Bugs
There are many dissimilar viruses that crusade breadbasket bugs. Some of which survive for a few hours outside of the body and others can last upwards to several months.
Salmonella and campylobacter are two types of bacteria that can cause stomach bugs. Both of these cause viruses that last a very short amount of time exterior of the trunk. These viruses last anywhere betwixt 1-iv hours on surfaces.
While these stomach bugs don't last very long, others like norovirus and clostridium difficile survive for days and sometimes weeks at a time, according to the NHS.
Just like the flu, droplets from stomach viruses tin survive when someone vomits, leaving these droplets to spread onto surfaces. This is specially mutual with norovirus, which is why information technology'south of import to clean surfaces if you or someone y'all live with has a stomach bug.
Luckily, stomach viruses tin can exist hands prevented. Virtually stomach viruses can exist removed from surfaces with cleaning and prevented by frequent washing the easily.
MRSA and Herpes
Other viruses, like the staphylococcus aureus bacteria, which causes MRSA, typically lasts a few days to weeks exterior of the torso, like stomach viruses. They can final longer than colds and flus, considering they don't need as much wet to survive on hard surfaces.
The herpes virus dies the quickest outside of the body. It'south a virus that's passed by homo-to-human, typically through kissing or oral sex, and can stay active on the skin. Although, the virus dies very apace when information technology's away from skin.
Prevention and Protection from Viruses
Prevention of viruses isn't guaranteed, but there are a couple elementary steps to protect yourself against them.
Washing your easily regularly volition greatly reduce your gamble of catching a virus. The step is even more than important if you touch your face frequently throughout the day.
Some other way to requite yourself actress protection is by using sanitation wipes or cleaners to clean surfaces around your house or office.
