Investigations are not generally repeated for relapse unless there is a specific medical indication or possible adverse effects from antipsychotic medication. In children hallucinations must be separated from typical childhood fantasies. It is difficult to distinguish childhood schizophrenia from autism. Prevention
Prevention of schizophrenia is difficult as there are no reliable markers for the later development of the disorder. It is unclear as of 2011 whether treating patients in the prodrome phase of schizophrenia provides benefits. : 43  There is a discrepancy between the growth in the implementation of early intervention programmes for psychosis and the underlying empirical evidence. : 44 There is some evidence as of 2009 that early intervention in those with first-episode psychosis may improve short-term outcomes, but there is little benefit from these measures after five years. Cognitive behavioral therapy may reduce the risk of psychosis in those at high risk after a year and is recommended in this group, by the National Institute for Health and Care Excellence (NICE). Another preventive measure is to avoid drugs that have been associated with development of the disorder, including cannabis, cocaine, and amphetamines.Antipsychotics are prescribed following a first-episode psychosis, and following remission a preventive maintenance use is continued to avoid relapse. However, it is recognized that some people do recover following a single episode and that long-term use of antipsychotics will not be needed but there is no way of identifying this group. Management
The primary treatment of schizophrenia is the use of antipsychotic medications, often in combination with psychosocial interventions and social supports.
Those who survived often had prolonged residual neurological symptoms. Viral RNA was detected in survivors up to 170 days after infection and infectious Chapare virus was obtained in a semen sample of one patient 86 days after symptom onset. Treatment
Treatment relies mostly on supportive care and early diagnosis. Specific antiviral therapy for Chapare virus infection has yet to be properly investigated. References
