More than 3,000 people were infected with brucellosis in the town of Lanzhou, in northwest China. An investigation by the city’s Health Commission reveals that this outbreak was caused by a bacterial leak that occurred in a factory biopharmaceutical at the end of July and August of last year.
According to the health authorities, 22,000 people were analyzed and 4,646 tested positive for antibodies to the disease, of which 3.245 confirmed the contagion in subsequent tests. For now they have not reported deaths from this disease.
The leak in the biopharmaceutical factory occurred when they produced brucella vaccines for animal use, for which they used expired disinfectants. This means that not all bacteria were eradicated in the waste gas. This polluted waste gas formed aerosols They contained the bacteria and leaked into the air.
Symptoms and transmission
The disease, also known as Malt fever or Mediterranean fever, can cause symptoms that include headaches, muscle aches, fever, and fatigue.
The Centers for Disease Control and Prevention of the United States (CDC), assure – according to the CNN – that the transmission of brucellosis between people is extremely rare and the majority of human infections are generated by eat contaminated food or breathing in the bacteria, as seems to have happened in this Chinese city.
In Spain, this disease has been present and in November of last year, it was when the European Union declared that the province of León was free of bovine brucellosis, a fact that supposes “a health milestone of the first order “ and a consolidated step in improving the sanitary status of the provincial cattle herd.
