Corona Virus Stays on the Surface of Things How Long? These Facts Appropriate Research
Did you know that the Corona virus can last for several days on the surface of an object? Corona virus defenses on the surface of an object are not always the same, depending on what objects are exposed to the virus.
As quoted from The Economic Times, the risk or danger of infection that may be caused when someone touches the surface of an object is still relatively light. But it is different from viruses that are in the air. Viruses in the air might be a bit more dangerous for medical workers.
According to a study published in the New England Journal of Medicine, the virus will be destroyed in just one day if it is on a cardboard box. Therefore you don’t need to worry too much that the shipment will spread the virus, unless the person delivering the package has coughed or sneezed or has touched it with contaminated hands. If you are worried about the danger of infection from the package you received, you can wipe it off first using disinfectant wipes, then wash your hands thoroughly.
How long does the Corona virus last on the surface? The Journal of Hospital Infection analyzes 22 studies on the Corona virus. Here is the result, about how long the Corona virus stays in the throes of something:
-In stainless steel, corona virus can last up to 5 days
-In metal, corona virus can last up to 5 days
-In aluminum and surgical gloves, the corona virus can last for 2-8 hours
-In wood, corona virus can last up to 4 days.
-On the glass, corona virus can last up to 4 days
-In plastic, corona virus can last 8 hours to 6 days
On paper, the corona virus can last 4 to 5 days
-In PVC, corona virus can last up to 5 days
-In ceramics, corona virus can last up to 5 days.
When a virus is suspended in droplets smaller than 5mm, it is known as an aerosol. According to the researchers, when the virus is still suspended in the form of aerosols and has not been attached to the surface of the object that makes it able to live longer, the virus can remain suspended for approximately half an hour. This discovery is certainly very contrary to the statement of WHO (World Health Organization) which says that the virus cannot be spread through the air.
The virus that is in the air is actually not very dangerous for people who are not near people who have been infected. That is why viruses in the air are more risky for medical workers. No wonder why medical staff are required to wear full clothing or hazmat costumes along with special eye glasses and nose and mouth masks to protect the body.
“After getting a patient with severe pneumonia, the patient needs to be intubated,” said Dr. Vincent Munster, a virologist at the National Institute of Allergy and Infectious Diseases who led the research. “All of this treatment might produce aerosols and drops,”
Several other studies, such as research from the JAMA (Journal of the American Medical Association) which was published on March 4 also said the same thing, namely viruses can be spread through the air. The Singapore-based study found that viruses in ventilators in hospital rooms of infected patients can spread through the air.
Other proof is done by comparing cigarette smoke or foggy breathing at very cold temperatures. From there it was found that the closer and faster a person breathes, the more scent is captured. For those who are farther away, there will be only a few viruses that are captured and have little potential to become a danger.
To assess the ability of the virus to survive in the air, Munster conducted an experiment using rotating drums to suspend aerosols and provide temperatures and humidity levels similar to hospital conditions. From these experiments it was found that the virus can last up to 3 hours, but its ability to infect will decrease dramatically during that time period.
“We need more experiments like this, in particular, extending the experimental sampling time for aerosol viruses above three hours and testing survival under different temperature and humidity conditions,” Dr. Jeffrey Shaman, an expert in environmental health science at Columbia University.
