Dengue infection can have spectrum of manifestations, often with an unpredictable clinical progression and outcome. There have been increasing reports of atypical manifestations. Abdominal pain or tenderness and persistent vomiting (warning signs) are present in the majority of cases with severe dengue prior to clinical deterioration. We report a 10-year-old child who presented with fever, persistent vomiting, and abdominal pain. A diagnosis of acute pancreatitis was made. This is a very infrequently reported complication of dengue hemorrhagic fever...

The World Health Organization (WHO) has coined the term expanded dengue to describe cases which do not fall into either dengue shock syndrome or dengue hemorrhagic fever. This has incorporated several atypical findings of dengue. Dengue virus has not been enlisted as a common etiological agent in several conditions like encephalitis, Guillain Barre syndrome. Moreover it is a great mimic of co-existing epidemics like Malaria, Chikungunya and Zika virus disease, which are also mosquito-borne diseases. The atypical manifestations noted in dengue can be mutisystemic and multifacetal...

Arboviruses cause very recurrent epidemics, the oldest Dengue, known especially outside the flu-like syndrome with high fever mainly impacting vulnerable populations, may be responsible for severe hemorrhagic fevers, but also a few cases of Guillain-Barré syndrome. In 2014, the French Antilles occurred an outbreak of Chikungunya, following that of the Reunion's outbreak. During this period have been described, the articular and musculo-squellettic lesions, responsible for loss of autonomy in populations already carriers of chronic inflammatory joint damage or mechanical, but also a heavy impact on the autonomy of elderly and frail people...

UNLABELLED: Zika virus (ZIKV) is a flavivirus that has emerged as a global health threat due in part to its association with congenital abnormalities. Other globally relevant flaviviruses include dengue virus (DENV) and West Nile virus (WNV). High-resolution structures of ZIKV reveal many similarities to DENV and suggest some differences, including an extended glycan loop (D. Sirohi, Z. Chen, L. Sun, T. Klose, T. C.

BACKGROUND: Dengue fever (DF) outbreaks present regionally specific epidemiological and clinical characteristics. In certain medium-sized cities (100 000-250 000 inhabitants) of São Paulo State, Brazil, and after reaching an incidence of 150 cases/100 000 inhabitants ("epidemiological threshold"), clinical diagnosis indicated dengue virus (DENV) infection. During this period, other seasonally infectious diseases with symptoms and physical signs mimicking DF can simultaneously occur, with the consequential overcrowding of health care facilities as the principal drawbacks...

The majority of dengue viral infections are asymptomatic, though symptoms may range from self-limiting febrile illness to life threatening hemorrhagic manifestations. As the burden of disease is dramatically rising in recent years, more patients with atypical presentations and rare complications are increasingly reported. Dengue virus may rarely involve different organ systems including CNS, liver, and heart. However, involvement of eye and thyroid is extremely rare. We present a case of 32-year old patient who presented with conjunctivitis and subacute thyroiditis and was found to have dengue viral infection as the cause of these conditions...

Dengue is an important infectious disease that has high morbidity and mortality rates in most tropical and subtropical areas of the world. The diversity of the clinical manifestations involved in the outcome of dengue virus infection is affected by the relationship between serotype/genotype of the virus, host immune status, host genetic background, and environmental factors. Polymorphisms in interleukin (IL) genes have been associated with risk of developing symptomatic dengue. This study aimed to determine the association of the single-nucleotide polymorphisms of IL1β -511C>T, IL1RN 86 bp VNTR, and IL6 -174G>C genes with the clinical features of 198 individuals admitted to the São José Infectious Diseases Hospital with suspected dengue infection...

Travelers returning from the tropics with fever remain a diagnostic challenge. Fever and chills suggest malaria, but may be present in dengue, chikungunya and influenza, and splenomegaly favors malaria or typhoid fever. In terms of laboratory tests, leukopenia suggests dengue fever, chikungunya fever or influenza. Atypical lymphocytes are present in malaria, dengue fever, chikungunya fever and influenza HAV, but not typhoid fever. Thrombocytopenia is profound in dengue fever, is also present in influenza and malaria...

Chikungunya virus (CHIKV) was recently introduced into the Americas. In Nicaragua, the first endogenous transmission of CHIKV was recognized in September 2014. We used an ongoing dengue cohort study of children aged 2-14 years in Managua, Nicaragua, to document the attack rate of symptomatic chikungunya in a presumably naive population. From September 2014 through March 2015, the overall clinical attack rate of laboratory-confirmed CHIKV infection was 2.9% (95% confidence interval [CI]: 2.3%, 3.4%). The attack rate was greater in children ≥ 8 years of age (4...

Dengue is endemic in more than 100 countries in Southeast Asia, the Americas, the western Pacific, Africa and the eastern Mediterranean regions. The virus is transmitted by Aedes mosquitoes. Dengue disease is the most prevalent arthropod-borne viral disease in humans and is a global and national public health concern in several countries. A seasonal pattern of dengue disease is consistently observed. The highest incidences usually correspond to the period of highest rainfall and humidity, providing suitable conditions for Aedes aegypti breeding and survival...

BACKGROUND: Dengue is the most common mosquito-borne viral disease in humans. Recently, there has been an epidemic shift of dengue from mainly affecting children to affecting more adults with increased severity. However, clinical factors associated with severe dengue in adults have varied widely between studies. We aimed to identify the clinical factors associated with the development of severe dengue according to the World Health Organization (WHO)'s 2009 definition. METHODS: We conducted a prospective study of adults with dengue admitted to the Hospital for Tropical Diseases in Bangkok, Thailand, from October 2012 to December 2014...

With dengue fever emerging as a global health problem and more Australians travelling to endemic areas, imported dengue infection is on the rise and clinicians need to remain vigilant. Primary cardiac and neurologic involvement in dengue infection has been rarely described in the medical literature and the pathophysiology is poorly understood. A rare and fatal case of primary dengue infection in a 34-yearold woman who returned from Papua New Guinea is reported; the unusual features of this case include severe primary dengue infection, myocarditis, and acute cerebral oedema resulting in death...
