viruses like flu could survive on toys long enough to result in exposures time, place children at risk of contracting infectious diseases , according to researchers at Georgia State University.
children’s toys can Harbour infectious virus
The researchers tested the time an enveloped virus could survive with toy pieces a flexible plastic for children, a frog chirps. They were able to recover infectious virions (complete viral particles) from the toy until 24 hours after contamination toy 60 percent relative humidity, and up to 10 hours at 40 percent relative humidity.
‘Toys in common areas play in healthcare settings have been implicated as vehicles of outbreaks of viral diseases.’
These findings show enveloped viruses could survive on toys long enough to result in exposures time. Enveloped viruses have an outer protective layer that can help you survive and infect other cells. Examples of such viruses include influenza and coronavirus, such as severe acute respiratory syndrome (SARS) or Middle East Respiratory Syndrome (MERS).
“People really do not think about getting the virus from inanimate objects,” said lead author Richard Bearden II, who has a master of science degree in biology from Georgia State University. “They think of getting them from other people. Children are vulnerable to infectious diseases because they put their hands and other objects in their mouths, and their immune systems are not fully developed.”
Toys can be an important channel for transmission of viral diseases in children. Previous studies have found viral contamination of shared care centers, doctor’s offices and homes toys.
However, it has remained unclear how long enveloped viruses can survive on inanimate objects, so it is difficult to assess the potential risk of infection control measures and efficient computing, such as disinfection. This study investigated how long it takes for a wrap to be inactive on the surface of a toy for children to typical indoor temperatures and relative humidity levels virus.
For the study, researchers used an enveloped bacteriophage, a virus that infects bacteria, to model what the survival of viruses that infect humans may be similar. virus in the toy humidity controlled environments at 22 degrees Celsius, either 40 percent or 60 percent relative humidity are placed.
For a 24 hour period, one percent of infectious virus remained in the toy 60 percent relative humidity, showing a reduction of 99 percent in the number of infectious virus.
“It is likely that the research team could have recovered beyond infectious virions 24 hours,” Bearden said.
The virus was less stable at 40 percent relative humidity, which is more common in indoor environments. In the first two hours, 0.01 percent remained virus, showing a reduction of 99.9 percent in the number of infectious virus. The researchers were able to regain 0.0001 percent of the infectious virus at 10 hours.
However, if any virus remains, there is a risk that children can get sick. indoor relative humidity can vary depending on where a person lives, so it is important to focus on preventing the spread of the disease, Bearden said.
“I think the main focus should be for parents, day care centers, doctors’ offices and other places where children share toys to implement some kind of strategy for decontamination to ensure that toys are not a reservoir of the disease,” he said .
For example, the toys that are shared often be decontaminated. household bleach is one of the best cleaning solutions. It is also recommended toys in health rooms waiting eliminate. A decontamination plan could also include door handles, elevator buttons and other commonly shared surfaces, Bearden said.
