Explaining the mechanism of action of this method, Mr. Quang said, test participants will be gargling with salt water. This solution is then put into a test tube and placed in the test device. If in other methods, the time to return the results will take from half an hour to several hours. Meanwhile, with this method, it only takes 10 seconds to produce results, Mr. Quang shared. Bkav CEO Nguyen Tu Quang. Photo: Trong Dat To do this, Bkav uses a frequency band of light shining into the test tube containing the patient’s saline solution, which is collected by the sensor at the output. Bkav’s artificial intelligence technology will help measure how much frequency is absorbed. Different frequencies of absorption produce different types of disease, in this case Covid-19. Mr. Quang said: “The naked eye can’t recognize the difference of those absorption frequencies. We have to train the AI ​​to know which is the specimen of the Covid patient and which is the human sample. not infected with Covid-19”. According to Quang, Bkav’s method of testing for Covid-19 with saline mouthwash solution will give faster results than conventional methods. The founder of Bkav company said that compared to the method of testing Covid-19 by breath, the salt water test technology is simpler, with the investment money for a testing unit much cheaper, even almost no cost. This test method has been tested by Bkav since the end of 2020 at the Central Hospital for Tropical Diseases. “Initial results were recorded as positive with a recognition rate of over 90%,” Mr. Quang said. According to CEO of Bkav, this business is the second company in the world to develop saline testing technology. Previously, a company in Israel had developed this technology.

Also according to Prof. Dr. Le Thi Quynh Mai, B.1.617.2 data on GISAID currently has not recorded the loss of Y144 mutation, so this mutation needs to be further monitored and studied. GISAID is an updated map of SARS-CoV-2 gene sequencing results, which is continuously updated by scientists around the globe. This map was consulted by scientists in different countries, closely following the evolution of the SARS-CoV-2 virus. Earlier, at the National Online Conference on the situation and urgent solutions to prevent and control the Covid-19 epidemic taking place on the morning of May 29, Minister of Health Nguyen Thanh Long informed: The strain is currently common in Vietnam. Nam is an Indian strain that has shown signs of increased infectivity and more severe disease compared to previous outbreaks.

The large-capacity “field” Covid-19 laboratory at the Bac Giang Center for Disease Control has been fully installed with the cooperation and transfer support of the Military Medical Academy (Hanoi). This area has an area of ​​​​about 200 m2 and was built quickly in 3 days. The center consists of 8 specialized rooms. In which, 2 laboratories meet biosafety level 2. The most dangerous room is the initial sample processing room. This is the workplace of many officers from the Military Medical Academy, Bac Giang Center for Disease Control and volunteer technicians. Responsible for operating the laboratory is Lieutenant Colonel, Dr. BS Ho Huu Tho (Head of Department of Gene Technology and Cell Genetics, Military Medical Academy). According to Dr. Tho, the special feature of this laboratory is that the SARS-CoV-2 virus detection process is highly sensitive, with the cost savings being reduced by nearly half compared to traditional methods. At the same time, the center has the capacity to test tens of thousands of people every day. According to Dr. Tho, this is the world’s first gene technology, using artificial intelligence to analyze PCR results to detect SARS-CoV-2 pathogens (known as AIMS RT-PCR technology). The sensitivity of this method was evaluated against an in vitro RNA standard set for a detection threshold of 7.2 copies/reaction, nearly 7 times lower than the WHO recommended procedure, when evaluating under the same experimental conditions (50 copies/reaction). This study was clinically evaluated on 142 positive cases, 1,034 negative cases for SARS-CoV-2 and 14 other respiratory viruses. The sensitivity and specificity of the method were both 100%. More importantly, the procedure was successful in mixing 100 patient samples in a single real-time reaction without compromising sensitivity. As such, this is a simple, super-sensitive and potential test method for large-scale screening of SARS-CoV-2 with cost savings many times over. According to Dr. Tho, this method is like a weapon we switch from a defensive state to an attack against the Covid-19 epidemic. To communicate with the staff working in the lab, the commander had to use a walkie-talkie system because the windows were always foggy because of the mist and Chloramin B disinfectant. Besides, the technician was wearing clothes For protection, entering the lab will be called by the number corresponding to the job they are undertaking. After each opening to receive samples, the room is sprayed with disinfectant to avoid the risk of infection. All generated waste is also collected and treated according to regulations of the Ministry of Health. To maintain testing capacity, nearly 100 cadets of the Military Medical Academy are divided into small teams working for 8 hours, with 3 rotating teams each day to ensure that the laboratory is always open 24 hours a day. Tran Hoang Minh (student of Military Medical Academy) and friends relax before the shift. He is in charge of the work of separating and taking samples, so the risk of infection is very high. However, Minh feels proud to work at this center. “The laboratory capable of large-scale testing is a very powerful weapon in the fight against the epidemic. With mobilized human strength, strong weapons and high determination, I believe the epidemic will be quickly controlled.” male students share.

As of 7am on May 11, related to the National Hospital for Tropical Diseases 2, there were 89 Covid-19 cases, of which 78 were at the hospital, 23 were Hanoians and 55 were at other hospitals. other province. Previously, as the new Han Newspaper reported, on the afternoon of May 9, the Ministry of Health announced the results of gene sequencing of the National Institute of Hygiene and Epidemiology on 8 samples of patients with Covid-19 in 3 provinces and cities. streets: Hanoi, Hung Yen and Thai Binh. As a result, all 8 samples belong to the Indian variant B1,617.2. Step 1: Visit https://www.bluezone.gov.vn or download directly at App Store or CH Play.
