More than 2000 kinds of bacteria attached to mobile phones can survive for 24 hours!
In a popular science program at MBS TV station in Japan, such a problem was posed by taking the towel and mobile phone that people often touch as examples.
The answer is that the phone (smooth).
1. The virus survives on the phone for 24 hours
On a towel, the virus can only survive for about 15 minutes. Viruses prefer smooth things to towels and other rough-surfaced objects.
The National Institute of Allergy and Infectious Diseases (NIAID), the US Centers for Disease Control and Prevention (CDC) and other agencies also released new research on March 10 that said:
After 3 hours in the aerosol, live new coronavirus can still be detected; on the copper surface, the new coronavirus can survive up to 4 hours; the cardboard surface can survive up to 24 hours; on plastic or stainless steel surfaces, it can survive up to 2 to 3 days.
Virus droplets contaminate the surface of smooth objects such as mobile phones and spread to your hands through fingertip contact. If you use your mobile phone to wipe your eyes and eat, the bacteria will take the opportunity to enter the body and cause infection.
Therefore, even if you wash your hands after returning home, if you do not pay attention to the disinfection of personal items such as mobile phones, there is the possibility of being contaminated by the virus again.
2. How dirty is the unsterilized phone?
According to statisticians, on average, they click on the mobile phone screen more than 2,600 times a day, carry it out, and touch it at any time. Mobile phones have always been the “base camp” for a variety of germs.
18 times more bacteria than the toilet
A research report from Stanford University in the United States showed that among the 30 mobile phone samples, the number of bacteria and viruses in touch-screen phones was 18 times that of men ’s toilets, and thus became a vector for the spread of germs.
There are more than 2000 kinds of bacteria attached to mobile phones, and the total number of bacteria in 1/4 of mobile phones exceeds 10 times the normal value. The most common are Escherichia coli and Staphylococcus aureus, Salmonella, influenza virus, and other pathogens that also account for a relatively large proportion.
3. Disinfect the phone correctly
(1). First step. Turn off the power of the mobile phone, and wipe the grease on the surface of the mobile phone with a tissue.
(2). Second stepSpray medical alcohol with a concentration of 75% evenly on a sanitary napkin or soft cloth.
(3). Use alcohol cotton to wipe the screen, back, sides, button gaps, charging interface and other parts of the phone from the same direction from top to bottom.
(4). The fourth step. Let the phone stand for 5 minutes and wait for the alcohol on the surface of the phone to completely evaporate.
(5).The fifth stepWipe the inside and outside of the mobile phone protective case separately, wait for the mobile phone and the protective case to be wiped separately before wearing.
4. Disinfect the hands after touching the mobile phone
In addition to the disinfection of mobile phones we mentioned above, in daily life, we also often disinfect our hands. Especially after touching the phone, do not eat immediately or touch your mouth with your hands.
In life, we often use alcohol-based hand sanitizer to disinfect our hands, but it is worth mentioning that the alcohol concentration of hand sanitizer can only kill bacteria if it reaches more than 60% (75% is the best ), So when we buy alcohol hand sanitizer, we must watch the alcohol concentration carefully.
