Influenza viruses can live up to 48 hours on the surface if not disinfected. So what about Covid-19 and coronavirus?
Recently, a bank in China implemented measures to prevent coronavirus infection with ultraviolet disinfection and heat, then store money for 7 to 14 days before releasing to customers.
It is difficult to determine the specific time
CNN said it is impossible to determine the exact time coronavirus can survive on contaminated surfaces and objects. However, looking at some studies can see scientists are looking for clues on this issue.
Coronavirus is a common group of viruses in animals. In some cases, they are called zoonotic scientists, meaning they can be transmitted from animals to humans, according to the US Centers for Disease Control and Prevention (CDC).
Up to now, the host transmitting the coronavirus that causes Covid-19 is still a mystery. Previously, studies have shown that the theory that people infected with MERS (Middle East Respiratory Syndrome) is caused by camel virus, SARS (severe acute respiratory syndrome) is caused by civet virus.
According to research published in early February in the Journal of Hospital Infection , viruses in the coronavirus group such as SARS and MERS can survive on inanimate surfaces such as metal, glass, and plastic for up to 9 days if the surface is infected. Do not disinfect.
The study also showed that human coronavirus “can be effectively disabled by surface disinfection with compounds containing 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite. “or bleach for a minute.
“Based on available data from SARS, one of Covid-19’s closest relatives, we can see that the SARS virus lasts from 5 minutes to 9 days on unpasteurized surfaces,” said Dr. Charles. Chiu, infectious disease specialist at the University of California, San Francisco, USA, Director of USCF-Abbott Viral Discovery and Diagnosis Center “.
However, it is difficult to determine the specific duration of survival on the infectious surface of a new strain of corona virus because there are still many missing data. “Numerous 2019-nCoV culture studies are needed to give an exact answer as with SARS,” said Charles.
Do not be too panicked
According to the CDC , influenza viruses can survive on some surfaces for 48 hours and hide the possibility of infection if they are not cleaned and disinfected. However, the CDC notes that coronavirus spread primarily through virus-containing droplets and that they have “poor viability” on the surface. We can become infected by touching, holding and grasping contagious virus containers, but this is not the main way of infection.
Therefore, we should be calm and not be too panicked by the current situation. “More than 80% of patients with Covid-19 will recover. In addition, 14% of patients suffer from serious medical conditions such as pneumonia and shortness of breath. The death rate of the disease is 2%, ”Tedros Adhanom Ghebreyesus, director general of the World Health Organization, said during a press conference with the media.
Mr. Charles Chiu emphasized that we should announce the epidemic and need accurate and timely notices, but “do not panic”. “If you are worried, you should follow recommendations such as washing your hands regularly, avoiding contact with the sick person, and adhering to the principle of isolation,” Mr. Charles added.
