Keyboard disinfection

Keyboard disinfection is to eliminate a large number of pathogenic bacteria hidden on the keyboard.

With the development of information technology and the rapid popularization of computers, market surveys have found that in some public places with a large number of people, such as Internet cafes, libraries, and hospitals, computers are used as a public device. Most of them lack effective cleaning and disinfection measures, and the user's awareness of hygiene and prevention in this aspect is also very weak. Therefore, the keyboard of the computer (notebook) has become a source of hiding dirt and bacterial infection.

according to

The pathogenic bacteria on the keyboard can be divided into: Gram-positive bacteria, Gram-negative bacteria, epidemic viruses and parasites. All diseases that affect people's health are caused by the above germs.

1. Common Gram-positive bacteria are: Staphylococcus, Streptococcus, Pneumococcus, Anthracis, Diphtheria, Tetanus, etc .;

2. Common Gram-negative bacteria are: Escherichia coli, Proteus, Shigella, Pneumoniae, Brucella, Perfringens, Typhoid, Pseudomonas aeruginosa, Pertussis, Vibrio cholerae, and Meningitis Coccus, Haemophilus influenzae, Haemophilus parainfluenzae, Haemophilus parainfluenzae, Acinetobacter, Yersinia, Legionella pneumophila, Pertussis, Parapertussis, Shigella , Pasteurella spp., Vibrio parahaemolyticus, Pseudomonas Shigella, etc.

3. Common epidemic viruses are: hepatitis A, influenza A, avian influenza, SARS, hand, foot and mouth disease, trachoma, red eye disease, tetanus, and bacterial dysentery.

4, common infectious parasites are: roundworm, mite, lice, gonorrhea, syphilis, roundworm, roundworm, schistosomiasis and so on.

Diseases caused by Staphylococcus aureus

Staphylococcus aureus is the most common pathogen in human purulent infections. It can cause local purulent infections, but also cause pneumonia, pseudomembranous enteritis, pericarditis, and even systemic infections such as sepsis and sepsis.

Streptococcus disease

1. Purulent inflammation is invaded by skin wounds, causing purulent inflammation of the skin and subcutaneous tissues, such as palate, cellulitis, and erysipelas. Dilated along the lymphatic vessels, causing lymphangitis, lymphadenitis, sepsis, etc., invaded through the respiratory tract, often with acute tonsillitis, pharyngitis, and spread around the cause of abscesses, otitis media, mastoiditis, tracheitis, pneumonia, etc. Unsanitary delivery, infection through the birth canal, causing "puerperal fever".

2. Scarlet fever is an acute respiratory infectious disease caused by group A streptococcus that produces pyrogenic exotoxin. It is clinically characterized by fever, angina, systemic diffuse rash, and apparent desquamation after rash regression.

3 Allergic diseases caused by pathogenic bacteria after streptococcal infection

Rheumatic fever is caused by various types of group A streptococci. The clinical manifestations are arthritis and myositis. There are two types of pathogenic mechanisms: one is type II allergy, streptococcus fine-wall polysaccharide antigen and myocardial valve, joint tissue glycoproteins have common antigenicity, and wall protein antigen and myocardium have common antigenicity. The second is type III allergy, which may be caused by the deposition of immune complexes of M protein on heart valves and synovial membranes.

Diseases caused by Escherichia coli

The Enterobacteriaceae family includes a large group of Gram-negative bacteria with similar biological characteristics. Most of these bacteria live in the intestines of humans and animals, and can be widely distributed in water, soil and decay with human and animal excrement. Some of these bacteria have obvious pathogenic effects on humans, such as Salmonella, Shigella, and some pathogenic Escherichia coli. Most of them are normal intestinal flora and generally do not cause disease, but when Changes in the host's body state or the entry of bacteria into parts other than the intestinal tract can also be used as conditional pathogens to cause a variety of diseases, such as bacteremia, meningitis, pneumonia, pyelonephritis, or wound infections.

Diseases caused by roundworms

Ascaris lumbricoides, also known as chigger mites, is a Chinese celebrity type mites. It is a tiny worm that is invisible to the naked eye. It is approximately round or oval in shape. 0.35mm.

Scabietic mite invades human skin and causes itching, causing skin lesions such as papule, pustule, nodule, plaque, or vesicle or bulla The disease is known as scabies.

Diseases caused by mites

Mites belong to the class of tiny animals of the arthropod order Arachnididae, and their body sizes are generally about 0.5 mm, some are as small as 0.1 mm, and most species are less than 1 mm.

Mites come from contact and cross-infection. When the mites are just infected, they are easy to contact. Temperature and humidity are suitable for its growth and reproduction. Sebaceous glands are abundant, such as nose, forehead, and face.

Mites are one of the main culprits leading to allergic rhinitis. Mites like humid, high temperature, cotton or linen fabrics, or dusty environments. The hot and humid environment is the season when the mites develop and reproduce most vigorously. This will become a floating matter in the air. Causes a series of allergic reactions when inhaled by sensitive people.

Hand, Foot and Mouth Disease

Hand, foot and mouth disease is an infectious disease caused by enteroviruses. It occurs in children under 5 years of age and can cause herpes in the hands, feet, mouth and other parts. A small number of children can cause myocarditis, pulmonary edema, aseptic meningoencephalitis, etc. complication. Individual severely ill children may die if their condition develops rapidly.

Transmission channels:

1. The crowd is in close contact with the spread. Pass items such as hand towels, towels, computer keyboards, mice, and clothing that are contaminated by the virus. Public goods that the patient has come into contact with. (Body surface spread)

2. The patient's throat secretions (droplets) spread. (Respiratory transmission)

3. Drink or consume water and food contaminated by the patient. (Dietary transmission)

4. Food that virus bites crawl on.

5. Direct contact with the patient.

Red eye disease

Commonly known as "red eye disease" is infectious conjunctivitis, also known as outbreak of fire eye, is an acute infectious ophthalmitis. According to the different pathogenic causes, they can be divided into two types: bacterial conjunctivitis and viral conjunctivitis. The clinical symptoms are similar, but the prevalence and danger are mainly viral conjunctivitis.

The disease is mainly transmitted through contact, the most common being eye-hand-eye transmission. In addition, it may be infected by touching towels, handkerchiefs, face washing appliances, electronic game consoles, computer keyboards, etc. used by patients, or swimming or bathing in places such as swimming pools, baths, etc. that patients have touched.

Keyboard disinfection personal disinfection

It is recommended to take a photo before removing the keycap to facilitate reinstallation. Remove the keycaps in order, soak the keycaps with a high-concentration disinfectant for several minutes, remove the keyboard casing, wear protective gloves, and wipe the keyboard chassis with a slightly damp cloth dipped in disinfectant. Non-professionals must not use wet cloths to wipe circuit boards In order to avoid short-circuit failure or fire, place it in a ventilated place or dry in the sun. Do not leave water drops to avoid damaging the equipment or causing circuit failure. Or use the soft silicone cleaning mud in the cleaning kit to clean it.

Keyboard disinfection shop disinfection

Cleaning services are available at computer parts shops or repair shops. This method is more professional, safer, faster, and requires a small service fee.
