Be careful when computer operations are affected

Recently, the Department of infection management of Beijing youan Hospital Affiliated to Capital Medical University monitored the pollution of the keyboard and mouse of 20 public computers in a certain unit. The investigation found that on the keyboard of a public computer, it is often found that cookies, coffee powder, and hair are hidden in the gaps. The results of microbial culture showed that the number of bacterial colonies on the keyboard and mouse surface was as high as 65cfu/m2; staphylococcus aureus, Escherichia coli, Escherichia coli, Staphylococcus aureus, lysolassa and fungi were isolated.

According to reports, the relevant departments have performed a sampling check on the 200 computers and keyboards in several Internet cafes, and found that 35% of the remaining hepatitis B virus exists, which is quite serious. According to research by American scholars, the harmful bacteria they found on the computer keyboard and mouse are 400 times higher than the bacteria in the public toilet. Some computer-related staff often suffer from various skin diseases, eye diseases and gastrointestinal diseases for unknown reasons. The reason is that they do not pay attention to computer keyboard and mouse hygiene cleaning and disinfection.

 

Professor Li suying, an infection expert at Beijing youan Hospital Affiliated to Capital Medical University, believes that there are a large number of users using the keyboard and mouse of the public computer. In addition, the computer is not cleaned and disinfected for several years, the computer surface is often contaminated with the sweat and oil stains brought by computer users. The keyboard and mouse are also dusty. To this end, Professor Li reminded the majority of computer users that the computer will spread the disease as a medium. For example, staphylococcus aureus can cause skin infections (pustee ), e. coli bacteria can cause gastrointestinal diseases such as diarrhea through meals, and the presence of keyboard fungi can spread hand and other diseases. Therefore, we need to do a good job of Self-hygiene protection, enhance awareness of self-disease prevention, and wash hands before and after using the computer; do not eat anything during operations on the computer; in computer operations, try to avoid contact with eyes, ears, nose and mouth. It is best not to use computers with infectious diseases to avoid infectious diseases. Clean the keyboard and mouse regularly to keep the keyboard and mouse clean and clean to avoid bacteria. When using a public computer, such as a computer in an Internet cafe, wipe it with a sterile paper towel, avoid cross-infection.
