While SARS-CoV-2 is raging in the world, the brucella bacteria has quietly spread in Lanzhou, China due to human accidents. After the official understatement at the end of last year, no relevant data was released until 15 September 2020 when a bulletin was published on ScienceNet (see translation in News 2). However, the mainland media disclosed on 14 September 2020 that the number of infected persons exceeded the official data by more than ten times. One year has passed, and many infected people still cannot confirm whether they are sick, whether they should be treated or not, and what to do in the future.
In the cover report of Caixin Weekly, published on 14 September 2020, it was revealed that during the period from 24 July 2019 to 20 August 2019 of last year at the Lanzhou Biopharmaceutical Factory of China Animal Husbandry Co., Ltd., the leakage of brucella caused by human factors, at least caused more than 3,000 people in the surrounding area to be infected with brucellosis.
Officials in Gansu and Lanzhou did not report the accident until 26 December 2019, claiming that the reason was that the Lanzhou Biopharmaceutical Factory "used expired disinfectants" in the process of producing brucella vaccines for veterinary use, which resulted in the incomplete sterilization of waste gas from the fermentation tank. Bacteria-containing aerosols were discharged, causing infections among students and employees of the Lanzhou Veterinary Research Institute located in the downwind direction, resulting in positive antibodies.
At that time, the authorities classified the leak that lasted for a month as an "unexpected incident," and only announced that a total of 204 people from the Lanzhou Veterinary Research Institute and Lanzhou University were positive for antibodies, and no relevant data has been released since. However, Caixin Weekly stated that through field investigations by reporters, the number of infected persons exceeded the official data by more than ten times. As of the end of February this year, Lanzhou had tested 20,000 nearby citizens, and about 5,000 people were initially screened for infections with positive antibodies to the bacteria. Later, the provincial health and disease control department went into repair nuclear and confirmed that more than 3,000 people were positively infected.
Dr. Xiao En, a former virology researcher at the US Army Research Institute, pointed out that this infection figure shows that the Lanzhou leak was a major public safety incident.
Former U.S. Army Research Institute Virology Researcher Dr. Xiao En said, “Because this brucellosis is actually tens of thousands of cases nationwide every year. For example, in 2014, the total reported cases nationwide was about 57,000. And the United States has been more than 20 years old. Inside, there are usually cases of brucellosis every year, and the total number in the country is about 100 per year. So you can see that brucellosis has been prevalent in China in recent years, especially after 2000. There is a trend of rapid rise."
Lanzhou Biopharmaceutical Factory of China Animal Husbandry Co., Ltd. is known as one of the oldest veterinary vaccine manufacturers in China. It is a subsidiary of China Animal Husbandry Co., Ltd., a listed state-owned enterprise, and a designated manufacturer of major animal disease vaccines by the Ministry of Agriculture and Rural Affairs. The authorities classified the spill that lasted for a month as "an accidental accident," but Dr. Xiao En pointed out that the actual exposure of the pharmaceutical factory's problems is far more than that.
Dr. Xiao En commented, "Such leaks occurred within a month, indicating that there were serious leaks in multiple links in the entire production process. One is the purchaser. Maybe the reagents you purchased are not qualified or expired. Others may It is also poorly managed, that is, this product has been stored for too long and has become invalid. In addition, every inactivated vaccine produced must also be tested. You should soon find that the inactivated vaccine has not achieved the inactivated effect."
Zhu Wei, medical director of a pharmaceutical company in the United States, said, "It has once again exposed the serious problems in vaccine production in China. In fact, China has experienced many vaccine quality problems and even poisonous vaccine incidents over the years. It is now difficult for the people in China to trust domestic vaccines. The international community Especially developed countries will not trust vaccines made in China."
Patients infected with brucellosis will have fever, muscle and joint pain, fatigue, skin rash and even orchitis. However, the Caixin Weekly reported that most of these patients were not diagnosed and only received a "Shuangyang" (double-positive) test sheet. Some people did not even get their own report and test results, and they were were not diagnosed. The control department took them away. These people do not know if they are sick, whether they should be treated, and what should they do if brucellosis remains hidden in the body.
