According to the latest study, the novel coronavirus can last on plastic and stainless-steel surfaces for almost three days. The study also says that it can live in aerosols, the suspension of minute particles or droplets in the atmosphere for up to three hours. The United States National Institutes of Health-funded the study, and initially, it posted last week while further details published in the letter on Tuesday.
Basically, the research finds that the constancy of the virus SARS-CoV-2, which causes COVID-19, is, to some extent, similar to SARS-COV-1 under the experimental conditions. SARS-CoV-1 belongs to the family of coronavirus that sparked SARS (the Severe Acute Respiratory Syndrome) outbreak in 2002. The researchers understand after the results of the study of how long the COVID-19 can stay on surfaces and in the air. Still, they believed that more research required for it.
According to the letter, here below are some highlights of the findings:
- The novel coronavirus lives for about seventy-two hours after placed on plastic and stainless steel.
- It was viable for around four hours after placed on copper and for twenty-four hours after placed on cardboard.
- In atomizers, it remained viable all over the experiment of three hours.
The research work specifies that transmission of the novel virus is possible by the material as well as through aerosol since the COVID-19 can remain infectious and viable in aerosols for several hours while on surfaces for some days. The researchers wrote that these results echo those with SARS, in which these types of transmission linked with the spread in super-spreading social events as well as spread in a hospital setup.
Scientists still investigating COVID-19
Last month, a study published in The Journal of Hospital Infection states that human coronavirus, likewise SARS that causes SARS, found to keep on inanimate surfaces such as plastic, metal, or glass surfaces – for as long as nine days in case of not disinfecting that surface. SARS was the major interest of the researchers because it is too much close to the COVID-19.
Researchers still continue their work to investigate more, how long the novel coronavirus can linger in the air and even on surfaces, according to Dr. Maria Kerkhove of WHO. She said as everybody knows the virus transmitted through droplets, the little pieces of liquid.
When it comes out from an infected individual when he coughs or sneezes, the virus goes a certain distance, and then they settle on any surface around it. In that situation, it’s very important for the health care staff in health care facilities to take extra precautions like to wear masks and gloves.
How to Disinfect the novel Coronavirus from Surfaces
According to the United States Centers for Disease Control and Prevention (CDC) that the novel coronavirus thought to transmit mostly through respiratory droplets, for example, the droplets in a sneeze or cough. CDC said on its website that it might be possible that anyone can get infected with new coronavirus by touching the object or surface having the virus and then touch his hands to his nose, mouth, or even eyes.
The coronavirus driving the current pandemic can live on plastic and stainless steel surfaces for up to three days, according to a new study. And it can linger in aerosols — the suspension of tiny particles or droplets in the air — for three hours. https://t.co/KPiieAzBVn

The CDC encourages the people to clean and disinfect regularly touched objects and surfaces, such as doorknobs, cabinet handles, light switches, tables, and countertops. Cleaning of hands and face would done with soap and water, and disinfecting of surfaces and objects with alcohol solutions or bleach solutions describes the EPA-registered disinfectants or on the official website of CDC.
