Three thousand, two hundred and forty five people contacted brucellosis, due to a biopharmaceutical company leak in 2019.
Brucellosis is an infectious disease of animals that can also affect humans. The disease is also called Bang’s Disease. In humans, it’s known as Undulant Fever and Malta fever.
Brucella melitensis is seen mostly in goats,sheep and camels, while B. abortus is a pathogen of cattle, B. suis is found primarily in swine and B. canis is seen in dogs.
The Health Commission of Lanzhou in Gansu province in northeastern China has disclosed that 3,245 people have been confirmed positive for the bacterial disease, brucellosis which is as a result of an outbreak caused by a leak at a biopharmaceutical company last year.
Health officials announced that as of September 14, 21,847 people were tested, of which more than 3,000 were confirmed.
The outbreak started from a leak at the Zhongmu Lanzhou biological pharmaceutical factory last summer.
In December 2019, a joint research revealed that the Zhongmu Lanzhou biological pharmaceutical factory made use of expired disinfectants and sanitizers to produce Brucella vaccine and infected waste gas turned into aerosols that contained the bacteria that was carried by the wind down to the Lanzhou Veterinary Research Institute, and this was where the outbreak first hit.
The factory’s brucellosis vaccine production license was withdrawn in January. Seven other veterinary drug product approvals were also invalidated.
The Lanzhou Biopharmaceutical Factory then handed out an “apology letter” in February pleading that it had “severely punished” eight people who were pick out as accountable for the break out of the bacteria.
Brucellosis is one of livestock terrible diseases. Its effects includes decrease in milk production, emaciation, loss of young, infertility, and lameness.
Humans contact the disease via; Working with with infected animals that have not received vaccine for brucellosis. People who are more likely to be infected include farmers, slaughterhouse workers and veterinarians
They get infected due to direct contact with the animals or aerosols produced by the infected animal tissue. B. abortus and B. suis are most common. ; Another way to contact the disease is through ingesting unpasteurized dairy products.
Brucellosis is furthermore an occupational risk to laboratory staffs that do not handle specimens well or have an accident or spill. Brucella is very infectious in the aerosolized form.
The incubation period of brucella after contacting it is about 2-3 weeks, it could also be months. Symptoms may include fever, night sweats, severe headache and body aches and other non-specific symptoms.
