In late 2006, scientists from the Chinese Centre for Disease Control and Prevention of Hong Kong University and the Guangzhou Centre for Disease Control and Prevention established a genetic link between the SARS coronavirus appearing in civets and in the second, 2004 human outbreak, bearing out claims that the disease had jumped across species.It took 14 years to find the original bat population likely responsible for the SARS pandemic. In December 2017, "after years of searching across China, where the disease first emerged, researchers reported ... that they had found a remote cave in Xiyang Yi Ethnic Township, Yunnan province, which is home to horseshoe bats that carry a strain of a particular virus known as a coronavirus. This strain has all the genetic building blocks of the type that triggered the global outbreak of SARS in 2002." The research was performed by Shi Zhengli, Cui Jie, and co-workers at the Wuhan Institute of Virology, China, and published in PLOS Pathogens. The authors are quoted as stating that "another deadly outbreak of SARS could emerge at any time. The cave where they discovered their strain is only a kilometre from the nearest village." The virus was ephemeral and seasonal in bats. In 2019, a similar virus to SARS caused a cluster of infections in Wuhan, eventually leading to the COVID-19 pandemic. A small number of cats and dogs tested positive for the virus during the outbreak. However, these animals did not transmit the virus to other animals of the same species or to humans.
A person with disorganized schizophrenia may also experience behavioral disorganization, which may impair his or her ability to carry out daily activities such as showering or eating.The emotional responses of such people often seem strange or inappropriate. Inappropriate facial responses may be common, and behavior is sometimes described as "silly", such as inappropriate laughter. Sometimes, there is a complete lack of emotion, including anhedonia (lack of pleasure), and avolition (lack of motivation). Some of these features are also present in other types of schizophrenia, but they are most prominent in disorganized schizophrenia. Treatment
This form of schizophrenia is typically associated with early onset (often between the ages of 15 and 25 years) and is thought to have a poor prognosis because of the rapid development of negative symptoms and decline in social functioning.Use of electroconvulsive therapy has been proposed; however, the effectiveness after treatment is in question.
