The new coronavirus can be transmitted through contact, and it is important to wash hands and disinfect frequently. So, in general, which of the daily necessities are suitable for the survival of the virus “hotbed”? How long can viruses survive on the surface of these objects? According to the NHS website, the survival of the virus after it leaves the body depends on the surface of the object on which it is attached, as well as the conditions of the environment such as temperature and humidity.
Overall, viruses survive longer on non-permeable (water-resistant) surfaces, such as stainless steel or plastic surfaces, and relatively short on permeable surfaces such as fabrics or paper towels. The survival time varies between different types of viruses, some of which can survive for more than 7 days on the surface of indoor objects, although their disease resistance can decrease significantly within 24 hours. Therefore, the elevator buttons and door handles and other hard objects, is the need to be more careful of the virus carrier.
In a 2014 paper published in the American Journal of Infection Control by scientists from the United Kingdom, France, the United States, China and other countries, the survival of influenza A(H1N1) virus on the surface of four common objects was studied. The researchers conducted multi-point sampling of wood, stainless steel, plastic and fabric surfaces in the home. The results showed that the wood surface is the best “hotbed” of the virus, the virus can last 48 hours to maintain infection capacity, the virus in stainless steel and plastic surface sit until about 24 hours, attached to the fabric surface of the virus survival time is the shortest, the virus activity in 8 hours will rapidly drop to zero.
Another paper, published in the American Journal of Applied and Environmental Microbiology in 2016, looked more closely at the survival of h1N1 influenza viruses on stainless steel surfaces under different environmental conditions. Studies have shown that influenza viruses can survive up to seven days on stainless steel surfaces and are still infectious. The study demonstrates the “extra-long standby time” of influenza viruses on non-permeable surfaces.
The NHS website also says the flu virus can survive in the air for hours in the form of droplets, and that low temperatures increase its survival. However, the influenza virus survives on hand for a short period of time, and the number of viruses on hand drops to very low levels in about 5 minutes.
Researchers say maintaining good hand hygiene and regular disinfection of commonly used surfaces is important to slow the spread of the virus during outbreaks such as the flu season. Studies have shown that cleaning the surface of an item with a certain concentration of bleach, vinegar, detergent or antibacterial rags can effectively reduce influenza virus activity.
