![]() ![]() Only two cases of catatonic symptoms in dengue have been reported in published literature so far. There was rapid resolution of psychosis with low doses of antipsychotics in all these reports. ,, The symptoms reported are visual/auditory hallucinations, persecutory hallucinations, emotional lability, agitation and disturbed sleep, appetite and self-care. It can present during the acute phase as reported in this case report “Psychosis in Dengue Fever” published in this issue or can be a late manifestation. Dengue-related psychosis has also been reported in literature. 2012 even showed that the depressive and anxiety symptoms were positively correlated to the severity of fever, headache, joint pain, body ache, and retro-orbital pain. ,, All the studies demonstrated a significant female preponderance for depressive and anxiety symptoms. , Depressive symptoms were observed in 50%–60% patients initially which came down to about 5%–20% once the acute phase was over. However, about 50% of these patients developed insect phobia on recovery from dengue fever. , These symptoms, however, reduced in severity and frequency as the physical condition improved and only a few needed anxiolytics. ,, In the acute phase of the illness, nearly 90% of the patients exhibited thanatophobia (fear of death), 15-23% had panic attacks, and overall 80% had significant anxiety-related symptoms. Anxiety was found to be a prominent finding in all these studies. Only a few cross-sectional hospital-based observational studies have been conducted in acute dengue patients to evaluate for common mental disorders. ,, , Patients generally presented with talkativeness, authoritative and irritable behavior, grandiosity, increased sexual behavior, and reduced need for sleep, and symptoms were controlled rapidly within a week to month in all cases with mood stabilizers and antipsychotics. There have been numerous case reports of appearance of manic symptoms during febrile phase of dengue fever as well as in convalescence period. The psychiatric symptoms may accompany the acute phase of dengue or can be a late manifestation. ![]() The exact incidence of neuropsychiatric manifestation is, however, not certain due to lack of adequate studies. With increase in the number of cases of dengue, there are reports of different neuropsychiatric manifestations associated with this condition from different parts of the world. Mortality is high in cases of severe dengue, particularly in Asian countries (0.5%–3.5%). Severe dengue can present as dengue hemorrhagic fever with thrombocytopenia, plasma leakage, and organ impairment or dengue shock syndrome with circulatory failure. It can present as dengue fever with high-grade fever, headache, retro-orbital pain, joint pain, nausea, vomiting, and rash. , ĭengue fever has a variable clinical picture ranging from subclinical infection to life-threatening outcomes. ![]() Repeated infections increase the risk of severe dengue. Infection with one serotype does not provide immunity from other serotypes but prevents re-infection from the same serotype. Dengue virus has four serotypes, namely, DEN-1, DEN-2, DEN-3, and DEN-4 and infection with all four is responsible for dengue fever. It is caused by a positive-stranded encapsulated RNA virus belonging to the family Flaviviridae. ĭengue fever spreads from the bite of an infected female Aedes mosquito, primarily Aedes aegypti species and Aedes albopictus. The WHO launched “The Global Strategy for Dengue Prevention and Control 2012–2020” to address this threat of an impending pandemic and reduce the burden of dengue. Because of the rapid increase in incidence and widespread prevalence, dengue has become a major public health concern. Currently, as per the WHO, half of the world's population is at risk of dengue fever with nearly 50–100 million people being affected annually in over 100 endemic countries. In the late 1900s, there was a rapid increase in the cases of dengue fever leading to major epidemics in many parts of the world. It was first reported in 1789 by Benjamin Rush who gave the name “break bone fever” to describe the condition due to its association with joint pain.
