Last week, schools in various regions notified schools of corresponding school opening time notifications. Taking Xiangyang City as an example, Xiangyang Education Bureau issued the first autumn school opening notice. The city’s general high schools, secondary vocational schools (including technical schools), junior high schools, and elementary schools are scheduled to start on September 1. ; The kindergarten is scheduled to start on September 7; each college will determine the specific time for the start of school based on actual conditions.
In order to do a good job in the investigation of health risks and to usher in the fall of school with confidence, 77,000 faculty and staff in Xiangyang city began to undergo nucleic acid testing on August 23. Hairong Elementary School is one of the schools designated for testing in the urban area. On August 23, a total of more than 700 faculty members were tested for nucleic acid. Wang Juanjuan, director of the Moral Education Department of Hairong Primary School, said that starting from the 24th, we will enter the centralized training stage and actively prepare children’s education on epidemic prevention knowledge and life safety education.
After completing the nucleic acid test, the city’s faculty and staff are required not to leave Xiangyang unless necessary. Before school starts, the school will carry out the elimination of the campus and the training of teachers on epidemic prevention. City Hairong Primary School teacher Wang Lihong said that in addition to teachers’ participation in nucleic acid testing, other people who are in close contact with students and parents are also tested. After the start of school, all classes are required to carry out the morning and afternoon inspection system and the epidemic report system. It is also understood that after the start of school, 920,000 students in the city, including kindergartens and colleges, will also implement nucleic acid testing and screening for all employees in batches.
As the school starts in September, all colleges and universities should organize staff and students to conduct nucleic acid tests to ensure a safe learning environment. A large number of nucleic acid detection processes are inseparable from the support of Virus Transport Medias. Currently, the market is generally divided into activated and inactivated types according to the composition and function of Virus Transport Medias.
The inactivated type is an inactivated virus that reduces the risk of secondary infection and has lower requirements for the detection environment. Therefore, the inactivated type is generally used for nucleic acid detection in large groups, and the risk of detection is small. The inactivated type can instantly lyse the pathogen to release the nucleic acid, and the protective agent can prevent the accounting from being degraded; and the activated Virus Transport Media can maintain the activity of the virus in a wide temperature range, keeping the originality of the sample to the greatest extent, and can be used Extraction and detection of viral nucleic acid, cultivation and separation of viruses.
The activated type contains Hanks liquid foundation, gentamicin, fungal antibiotics, BSA (V), cryoprotectant, biological buffer and amino acids. A combination of multiple antibiotics has anti-bacterial and anti-fungal effects; bovine serum albumin (BSA), as a protein stabilizer, can form a protective film on the protein shell of the virus, making it difficult to decompose and ensuring the integrity of the virus; Hanks The neutral environment constructed by the buffer helps increase the survival time of the virus and the stability of infection. The activated Virus Transport Media is usually used for the collection and transportation of clinical influenza, avian influenza (such as H7N9), hand, foot and mouth disease, measles and other virus specimens, as well as mycoplasma, ureaplasma, chlamydia and other specimens.
Desheng can provide the above-mentioned inactivated and activated Virus Transport Medias. The two preservation solutions produced have a high detection rate and can be configured for different needs of customers to provide you with high-quality products.
