Recently, the COVID-19 epidemic has spread in many places in China, and it has risen again. At present, the airport immigration office, designated hospitals, and quarantine hotels, these three units that are strongly related to the movement path of foreign personnel after entering the country, have potential huge hidden dangers in the waste generated within these units! Relying on human management inevitably leads to a mix of secrets, requiring technical means to prevent and eliminate diseases before they occur at the source!

1、 Hidden dangers

There have been issues with cleaning and related personnel infection at domestic airport immigration offices and designated hospitals. 1. Nanjing City announced on July 20th: Regular nucleic acid testing samples for staff at Lukou International Airport

Among them, 9 positive cases have been detected. After comprehensive analysis and diagnosis by the municipal expert group, July 2021

From 0:00 on the 20th to 8:00 on July 21st, novel coronavirus was added to infect the local confirmed disease of pneumonia

Example 7, including 4 cases of mild and 3 cases of common type; Two new locally transmitted asymptomatic cases have been reported. The outbreak at Nanjing Lukou Airport originated from the improper washing and protection of cleaning personnel after completing their work, which may cause individual cleaning personnel to become infected and spread among them. At the same time, the company's cleaners also ensure the garbage removal of international and domestic flights, while other airport staff may become infected due to contact with cleaners or contaminated environments.

2. Zhengzhou City Announcement on July 31, 2021: Zhengzhou Sixth People's Hospital is an overseas asymptomatic hospital

Designated hospitals for the treatment of infected individuals. Since the first asymptomatic case was reported on July 30th,

As of July 31st, Zhengzhou City has reported a total of 28 cases, including 11 confirmed patients and 17 asymptomatic carriers. Most of these personnel occurred within the Sixth People's Hospital of Zhengzhou, involving cleaning staff, medical staff, hospitalized patients, etc., presenting a small-scale gathering state and exposing the hospital's loopholes.

2、 Reason

At present, it has been determined that COVID-19 can be transmitted not only through respiratory tract, but also through fecal oral transmission, contact transmission, etc. Despite the implementation of the New Solid Waste Law on September 1, 2020, which stipulates the need to strengthen the management of medical waste, especially in response to major infectious disease outbreaks. However, various regions have different opinions

The implementation of the New Solid Waste Law varies, and there is currently a lack of scientific and effective supervision and management methods, making it difficult to fundamentally solve the problem; The handling of solid waste and virus prevention and control is like dancing on the tip of a knife, involving a wide range of details and difficulties. A slight carelessness can easily lead to safety accidents. At present, there are four prominent issues in the collection process of waste and garbage.

During storage, the virus and bacteria grow exponentially. According to current national regulations, medical waste must be stored in hospitals for 48 hours and collected by qualified recycling companies. During the epidemic, it is required to be cleared daily. However, some medical waste produces noticeable odors during its retention in hospitals due to rapid microbial growth. In addition, some garbage storage containers are not even covered. Even if they are covered, there will be a strong upward airflow when the lid is opened for garbage disposal. The bacteria in the garbage bin will adhere to the aerosol and remain suspended in the air for a long time, causing cross infection. Although sanitation regularly disinfects, the timeliness of disinfection is difficult to guarantee. And the manual disinfection time is relatively random, which cannot ensure timeliness, effectiveness, and comprehensive coverage, which is not conducive to controlling the spread of viruses. Manual disinfection also increases operating costs.

2. Collection and transportation with infection source. Each link in the collection and transportation process needs to be disinfected, and the staff must strictly follow the procedures for operation and protection. The transport vehicles require professional sealed transport vehicles, and disinfection is also required when they arrive at the incineration site. Vehicles, transport buckets, etc. must be disinfected. Failure to follow the prescribed procedures in any of the intermediate links may lead to secondary transmission of the infection source, increasing related operating costs.

3. Low infectious waste and high infectious waste should be mixed and discarded. Especially for hospital medical waste, there is a distinction between low infectivity and high infectivity. Medical waste that comes into contact with patients, especially infectious patients, often poses a high risk. However, currently, most hospital infectious waste is not strictly distinguished, packaged uniformly, and cross adhered, which invisibly increases the amount of highly infectious medical waste generated and also increases the operating costs of hospitals.

4. Regulatory difficulties. At present, the garbage collection and management work in large and medium-sized cities in China is relatively complete, but in remote areas, due to regulatory difficulties, there are opportunities for illegal vendors to take advantage of. At the same time, most of the medical waste in large and medium-sized cities is still managed through manual transfer forms, and data monitoring is not timely. It is also difficult to collect data on the classification of medical waste.

3、 Countermeasures

Relying on human management inevitably leads to a mix of secrets and requires technical means to prevent diseases before they occur, and to eliminate them at the source! The solution of Baowomei's "Real time Processing System in the Hospital" can achieve a dual harvest of economic and social benefits by being proactive and preventing problems in advance.

Baowo Beauty Hospital Real time Processing System: With medium and advanced disinfectants as the core, combined with intelligent equipment and information collection and supervision system, intelligent disinfectors are configured to suppress and disinfection and sterilization viruses starting from the garbage cans at the source. The professional medical waste intelligent collection vehicles in the process of collection and management and the medical waste fire extinguishers before discharge will eventually destroy and inactivate into the hazard level of ordinary domestic waste, and the medical waste will be controlled at the source, which can maximize the risk of virus infection.

4、 Suggestion

In view of the severe situation of domestic COVID-19 prevention and control, as well as the huge risk of mutation and import of foreign viruses, it is suggested that public facilities such as entry-exit offices, designated hospitals, isolation hotels, airports and stations should be equipped with intelligent disinfection on the existing medical waste garbage cans to achieve automatic intelligent disinfection of garbage cans, and medical waste fire extinguishers should be equipped in places with large amount of infectious substances for local inactivation, so as to prevent the growth and spread of viruses from the source and reduce cross infection.
