Brucellosis in China

Date: 20 September 2020 Tags: Miscellaneous

Issue

Lanzhou City in China announced that a leak in a biopharmaceutical company last year caused an outbreak of brucellosis disease.

 

Background

According to the WHO, most cases of the disease are caused by ingesting unpasteurised milk or cheese from infected goats or sheep.

 

Details

 The factory used expired disinfectants that caused incomplete sterilisation of waste gas. This waste gas, which was carrying the disease-causing virus, subsequently formed aerosols as a result of which people were exposed.

 

Brucellosis

  • Brucellosis is a bacterial disease that mainly infects cattle, swine, goats, sheep and dogs. Humans can get infected if they come in direct contact with infected animals or by eating or drinking contaminated animal products or by inhaling airborne agents.

  • Symptoms of the disease include fever, sweats, malaise, anorexia, headache and muscle pain. While some signs and symptoms can last for long periods of time, others may never go away.

  • These include recurrent fevers, arthritis, swelling of the testicles and scrotum area, swelling of the heart, neurologic symptoms, chronic fatigue, depression and swelling of the liver or spleen. Human to human transmission of the virus is rare.

 

Other outbreaks

Hantavirus

 In March, China reported the death of a person from Yunnan Province who tested positive for the hantavirus.

 

African Swine Fever (AFS)

Amid the COVID-19 lockdown, an outbreak of ASF killed thousands of pigs in Assam and Arunachal Pradesh.

ASF is a severe viral disease that affects wild and domestic pigs typically resulting in an acute haemorrhagic fever. The disease has a case fatality rate (CFR) of almost 100 per cent.
