Are Mobile Phones Sources of Coronavirus and Infections?

Mobile phones may be Source of New Coronavirus

Epidemic situation of pneumonia infected by new coronavirus is Menacing. Many little friends are trapped at home and the phone reached inseparable degree from living room to kitchen, from bedroom to balcony. Where to go?

Open the chat software and swipe. Send a circle of friends.

Even in the toilet but mobile phone is also a invisible health concern.

Various protective things work But often ignore it Mobile phones may spread new coronavirus.

It was mentioned in the "New Coronavirus Infected Pneumonia Diagnosis and Treatment Program (Trial Version 4)" published by the National Health and Health Commission and the State Administration of Traditional Chinese Medicine. Channels can also be spread through contact."

1. Contact transmission refers to the direct or indirect transmission of pathogens through vehicles.

2. Direct contact transmission refers to a suitable intrusion portal where pathogens are transmitted directly from the source of infection to susceptible persons.

3. Indirect contact transmission refers to the transmission caused by indirect contact with contaminated objects, such as door handles, stair handrails, desktops, mobile phones, toys, laptops, and public space countertops.

4. In other words, in addition to wearing masks, washing your face, and washing your hands, if you neglect to disinfect your mobile phone, the hand that touched the mobile phone may be infected with the new coronavirus if it touches the nose, nose and eyes.

Do you know how dirty your phone is?

In addition to the possibility of spreading new coronaviruses, mobile phones have also been the base camp of germs.

Visible dirty is fingerprints and sweat dirt on the phone screen, and invisible dirty is a large number of germs hidden on the phone.

The BBC reported that the bacteria on the screen of the mobile phone used daily is 10 times more than the bacteria on the toilet.

The University of Surrey in the UK had conducted such an experiment. They imprinted the cell phone they used daily in a petri dish that benefited the growth of bacteria.

They wanted to see what bacteria were on the cell phone. Three days later, the result was dumbfounded.

Why are there so many bacteria on mobile phones, including tablets?

In fact, when we use them, the sweat, bacteria, dander, grease, etc. on our fingers are wiped back and forth on the mobile phone screen, body, etc., forming an invisible layer of belt.

There are many foulings of bacteria, and these foulings are also a hotbed of bacterial growth.

The bacteria in the air also take the opportunity to attach to the mobile phone, resulting in more and more bacteria on the mobile phone, a vicious circle.

The germs on the mobile phone will be transmitted through the fingertips and the screen. If you wipe the eyes and eat with the hands of the mobile phone, the germs will take the opportunity to enter the human body.

If you rub your eyes, pick your nose with your hand that has touched the phone, or take food without washing your hands, you may bring the bacteria on the phone into the body, causing various diseases, such as diarrhea, colds, eye infections, etc.

3 things to keep your phone away from viruses

1. Alcohol disinfection

After going out to use a mobile phone or have suspicious contact, it is recommended to disinfect the mobile phone once.

You can use a professional mobile phone disinfectant, or use cotton balls dipped in alcohol for disinfection.

When disinfecting a mobile phone, you should first use detergent to remove the grease on the surface of the mobile phone;

Dip a cotton ball into medical alcohol (concentration is 75%) to squeeze out the excess alcohol, so that the cotton ball is just moist but will not drip alcohol to prevent alcohol from flowing into the phone and causing the phone to malfunction.

You can also use alcohol to disinfect cotton pads, wipe directly to disinfect.

Use it gently to wipe the surface of the phone twice, except for the front and back sides of the phone, don't neglect the earpiece, microphone, earphone hole, charging wiring hole and the seam joint of the phone.

2. Go out and play less with your phone

In the current epidemic situation, try to avoid going out. When you have to go out, rarely take out your mobile phone to play, because it will inevitably touch the handrails, elevator buttons, curtains, shopping carts and other public parts.

If you use your mobile phone outside, remember to clean your phone when you go home and wash your hands.

3. Wash hands after use

The cleaning and disinfection of the mobile phone must be carried out with the hand to avoid the cross transmission of germs.

Be sure to wash your hands after using the mobile phone, avoid eating while playing with the mobile phone, and do not touch the skin of the face with the hand that just took the mobile phone to avoid infection.

The survival time of virus on mobile phone is 96 times that of towel. How dirty is the phone

The US Centers for Disease Control released a new study on March 10 stating that after 3 hours in the aerosol, the live new coronavirus can still be detected.

On the copper surface, the new coronavirus can survive up to 4 hours.

On plastic or stainless steel surfaces it can survive up to 2 to 3 days.


Japanese respiratory expert Yoshio Otani believes that the virus can only survive on rough surfaces such as towels for about 15 minutes, and on mobile phones, it can survive for up to 24 hours.


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.


Do you know how vulnerable your phone is to Viruses?

According to statistics, the average person clicks on the mobile phone screen more than 2,600 times a day. A study in the United States has shown that the amount of bacteria and viruses on mobile phones is 18 times that of toilets.

The number of bacteria on the surface of mobile phones reaches 120,000 per square centimeter, and there are more than 2,000 types of bacteria.


The most common are Escherichia coli and Staphylococcus aureus, Salmonella, influenza virus and other pathogens also account for a relatively large proportion.


Use 75% alcohol as disinfection method

Based on the commonness of life, when disinfecting mobile phones, we usually consider two kinds of disinfectant 84 (chlorinated disinfectant) and 75% alcohol.

84 Disinfectant is a highly effective disinfectant mainly based on sodium hypochlorite. It is corrosive to metals and needs to be soaked for 10 to 15 minutes to achieve disinfection effect.

It is not suitable for mobile phone disinfection.


Compared with 84 disinfectant, alcohol is more gentle. It is not corrosive, volatile, and will not cause irreversible harm to the human body and mobile phones.

Also, 75% alcohol is often used in medical disinfection, so it is more suitable for disinfection of mobile phones.


Spray 75% medical alcohol evenly on a sanitary napkin or a sterile soft cloth; use a sanitary napkin / soft cloth to wipe the screen, back, and sides of the mobile phone from the same direction from top to bottom, mobile phone button gaps, charging interface, etc.

Let the mobile phone stand for 5 minutes, wait for the alcohol on the surface of the mobile phone to evaporate, and complete the deep disinfection of the mobile phone.

If the mobile phone wears a protective sleeve, wait for the mobile phone to dry before re-wearing the protective case. Carry out comprehensive and detailed disinfection.

Because of the volatile nature of alcohol, it can not guarantee the long-term disinfection effect, if conditions permit, it can be disinfected 2 to 3 times a day.

What is Biomechanics?

    The field of biophysics known as biomechanics (bio-mechanics) uses the principles and techniques of mechanics to the quantitative analysis of mechanical issues in living beings. Its studies cover everything from entire organisms to systems and organs (including blood, body fluids, organs, bones, etc.), from bird flying and fish swimming to flagella and cilia movement to the movement of body fluids in plants. The three laws of energy, momentum, and mass conservation as well as the constitutive equations characterising physical attributes form the foundation of biomechanics. Research in biomechanics focuses on mechanical issues that are connected to physiology and medicine. It can be separated into motion biomechanics, biofluid mechanics, and biosolid mechanics depending on the various research objects.     Bio-mechanics belongs to the branch of biophysics. The research scope ranges from biological whole to systems and organs.   Table of Contents 1. O
