The new corona virus can remain active on carton boxes for a period of no less than a day, which is a longer period if the surfaces are of steel or plastic.
Since the outbreak of the new Corona virus (Covid 19), which has infected more than 110,000 people worldwide, has no question dominates “how the bacterium that causes it is so easily transmitted between humans.” While many viruses and germs can survive on the surface of ordinary things, the focus on making sure that the life of this new virus continues to help eliminate its epidemic.
In an effort to answer the answer, researchers in the United States of America tried to spread the virus on the surfaces of seven ores that are frequently found in homes and hospitals, to verify how long it retains its infectious properties.
And it appeared to them that the bacterium lasted longer than plastic and steel for a period of three days, as it was revealed to Vincent Munster and a team of researchers at the Laboratory of the National Institute of Viruses in Hamilton, Montana, who gave a description of these experiments in a new edition.
Here, hospital equipment and tools appear to be a potential carrier of the disease, as are the bars on which metro trains are attached.
However, there is still no conclusive evidence of the spread of the virus through the solids. Marlin Roberts, a microbiologist at the University of Washington School of Public Health says, “We do not yet know for certain whether one is susceptible to catching the Covid 19 virus from surfaces or solids contaminated with it. This is what I want to clarify. ”
Doctors realize from their examination of patients that the virus is present in the upper respiratory organs, that is, the possibility of spreading the infection when coughing or sneezing, and thus the spread and spread of droplets in the air and on surfaces.
In the Munster and his team report, we find this phrase: “The stability of the virus in the air and on surfaces is directly related to its speed of transmission, the virus particles must retain their life long enough after the host expels them and until a new host picks them up.”
Munster and his colleagues say the hypothesis of propagation through the air is the explanation for high-speed propagation cases, such as those that seem to have occurred in Boston, where more than 70 people were injured at a conference held by biotechnology company Bugin.
Scientists have investigated how long the virus lives on different materials, as well as in an air chamber. They waited a few hours or days, before they wiped these surfaces and examined the samples, to see if they could still infect cells in a Petri dish.
They found that the two substances that enhance the life of the virus are steel and plastic, as they were able to collect samples from it even after three days, which may take a little longer. But the virus did not survive long on copper surfaces; it died after only four hours. In the air chamber, he lived for about three hours.
Detailed studies are required to verify how the virus has spread, but new laboratory results indicate that it can survive on cardboard packages, such as those used by Amazon to deliver its orders, as well as mobile phone cases, as they are plastic.
With some viruses, such as the flu virus, anyone who touches any surface can attract millions of viral particles in a matter of seconds. Other studies show that an average human touches his face more than 20 times every hour. Likewise, cold weather and low humidity enhance the life of viruses for a longer period.
Hence the recommendation of health authorities that people wash their hands frequently and that they use alcohol cleaners to disinfect surfaces. Coronavirus is known to be relatively easy to kill; it is sufficient to wipe surfaces with antiseptics of alcohol and dilute hydrogen peroxide.
In a report issued in February, dealing with information about this type of virus, German researchers said that within one minute of cleaning the surface, it is possible to eliminate nearly a million viral particles and reduce the remaining number to 100, meaning that the risk of infection is greatly reduced.
Researchers from the National Institutes of Health compared the new virus to the SARS virus, and found that their lives were identical. Sars caused a pandemic in 2003, but it was not easily transmitted, meaning that there are other factors present in the accelerated spread of Covid 19.
With no full knowledge of the causes until now, researchers expect that a new corona virus carrier may get rid of it even before symptoms of the disease appear on it, and that infection with this virus is very possible with a small amount of it, or the so-called “infectious dose”.
Researchers say they are verifying how long the virus remains alive in mucus, sputum and stool, and at any exact temperature and humidity.
