recently, the outbreak of super fungi in the United States has attracted many people's attention. The death rate after infection with super fungi is very high. However, many people feel panic, so it has also become a hot topic recently. So how terrible are super fungi? How to prevent super fungi? This article brings you the methods and measures to prevent super fungi. Let's have a look.
How terrible are super fungi
According to the New York Times, when the Mount Sinai Hospital in New York City performed abdominal surgery on an elderly man last May, it was found that he was infected with a 'mysterious and deadly' fungus, and the hospital quickly isolated him in the intensive care unit. The man eventually died after 90 days in hospital, but the deadly fungus survived tenaciously. Many parts of the ward were invaded. The hospital disinfected the walls, beds, doors, sinks and telephones, and even removed some ceilings and floors. At present, this multidrug-resistant fungus called Candida auriculata is popular in 12 states such as New York, New Jersey and Illinois.
"Super fungi can survive on the skin of patients and medical staff and the surface of hospital facilities for a long time. If the infection control measures are not effective, it is easy to lead to explosive infection in the hospital." Chinese experts said that the culprit of the outbreak of super fungal infection in the UK in 2018 was a shared thermometer.
"According to the existing literature, most infected people have unexplained high fever, ineffective drug treatment, and accompanied by various manifestations such as organ failure and respiratory failure." Chinese professionals said. In 2018, the first case of clinical infection of Candida auriculae was found in China. The first strain of Candida auriculae in China was isolated from a 76 year old patient. This study was jointly completed by a team led by Wang Hui and Huang Guanghua, researcher of the State Key Laboratory of mycology, Institute of Microbiology, Chinese Academy of Sciences.
According to Netease News, there have been 18 cases of super fungal infection in China.
The source of Candida auriculalis is still unclear, whether it is an environmental fungus or a human symbiotic fungus. Researchers generally believe that this is a newly evolved new species with the ability to quickly adapt to the human host environment. It mainly causes blood infection, and the death rate is as high as 60%.
How to prevent super fungi
Key patient sensing and control measures:
1. Isolation of colonized or infected persons in a single room requires independent sanitary facilities in a single room.
2. For patients transferred from infected hospitals or foreign hospitals, isolation measures shall be taken until screening results are obtained.
3. Strictly follow standard precautions, wash hands with running water and soap, and disinfect hands with quick drying hand disinfectant.
4. Personal protective equipment, such as gloves and aprons, should wear isolation clothing if there is a risk of contact with the patient's skin or the patient's blood and body fluids.
5. Personal protective equipment should be worn after hand washing and before entering the room or patient area, and removed and discarded in the patient's room. Before leaving, wash hands thoroughly and wipe hands with quick drying hand disinfectant.
6. Patients and visitors need to master infection prevention measures (brochures can be used), including hand hygiene and how to use aprons.
7. Disposable items such as sphygmomanometer cuff, pillow, etc. should be considered, especially during the outbreak.
Terminal disinfection:
1. Once the patient leaves the environment, terminal disinfection should be carried out. Clean first and then disinfect all places that may be touched by the hands of patients and medical personnel.
2. If any non-contact disinfection (such as gaseous hydrogen peroxide or ultraviolet light) is used, it shall be thoroughly cleaned before it.
3. If patients need medical examination or surgery, they should be ranked last on the day, and the environment is clean, as described above.
Cleaning and disinfection of equipment:
1. All equipment shall be cleaned in accordance with the manufacturer's instructions.
2. Special attention shall be paid to the cleaning and disinfection of reusable instruments, such as pulse oximeter, thermometer probe, etc.
Disposal of waste and fabrics:
1. Pay attention to reasonable packaging to avoid environmental pollution by waste and fabrics.
2. In pediatrics and neonatology, attention should be paid to the correct disposal of used diapers.
3. Contaminated items should not be discarded or cleaned in the sink at any time.
