On Tuesday, authorities said that in northwest China, thousands of people have tested positive for bacterial disease, and the outbreak was occurred due to a leakage at a biopharmaceutical firm in the previous year.
Lanzhou’s Health Commission, the Gansu province’s capital city, declared that around 3,245 people got the disease brucellosis, which is usually created by contact with livestock containing the bacteria Brucella.

The Health Commission of the city said that another 1,401 people got tested as preliminarily positive, although there were no fatalities reported. Moreover, the health authorities just tested 21,847 number of people out of the 2.9 million population of the city.
The spreading disease, even known as Mediterranean fever or Malta fever, can create symptoms that include muscle pain, fatigue, fever, and headaches. According to the U.S. CDC, some of the symptoms can be long-lasting or never go away, such as arthritis or swelling on particular parts of the body.
Man-to-man spreading diseases are rare
The United States CDC said that person to person transmission of the disease is extremely rare. Except for this, it could be possible that most of the people are infected by eating polluted food or breathing in such an atmosphere where bacteria largely present, and this seems to have happened in the case of Lanzhou.
The disease stemmed from leakage in the Zhongmu Lanzhou biological firm; that incident occurred between from end of the July to the end of the August in the last year, said by the Health Commission of the city. While providing Brucella vaccines for animal use, the firm used expired sanitizers and disinfectants, which means that not all bacteria were removed in the dirty or waste gas.
The dirty waste gas made aerosols that contained the bacteria and fused into the air, and further, it was carried by air down to the LVRI (Lanzhou Veterinary Research Institute), where the disease initially attacked.
Furthermore, people at the association started confirming infections in November, and it abruptly boosted up. By late December, around 181 people of the institute had been declared infected with that disease, said by Chinse media Xinhua.
The state-run news company, Xinhua, reported that other infected people included faculty and students of Lanzhou University; the disease also blows out to Heilongjiang province, the northeastern corner fo the country, where thirteen positive cases had operated in the veterinarian company in August.
