INTRODUCTION Viral etiologies of fever, including dengue, Chikungunya, influenza, rota and adeno viruses, cause major disease burden in tropical and subtropical countries. The lack of diagnostic facilities in developing countries leads to failure to estimate the true burden of such illnesses, and generally the diseases are underreported. These diseases may have similar symptoms with other cause...

BACKGROUND Chikungunya virus is a mosquito-borne alphavirus which causes an acute febrile illness associated with polyarthralgia. Beginning in August 2013, clinicians from the Yap State Department of Health in the Federated States of Micronesia (FSM) identified an unusual cluster of illness which was subsequently confirmed to be chikungunya virus disease. Chikungunya virus disease previously ha...

Introducción: las manifestaciones atípicas por el virus Chikungunya son poco frecuentes, presentándose sobre todo en adultos mayores y lactantes, se presenta los extremos de la vida, frecuencia va del 9 % - 33 %. La mortalidad es elevada. Objetivo: presentar 4 pacientes con atribuida a infección Chikungunya, internados Departamento Medicina Interna Urgencias Adulto Hospital Nacional febrero-mar...

During a 2014 outbreak, 450 patients with confirmed chikungunya virus infection were admitted to the University Hospital of Pointe-à-Pitre, Guadeloupe. Of these, 110 were nonpregnant adults; 42 had severe disease, and of those, 25 had severe sepsis or septic shock and 12 died. Severe sepsis may be a rare complication of chikungunya virus infection.

Here, we present four patients with confirmed Chikungunya virus infection showing atypical neurologic manifestations and death. This case series includes patients ranging in age from five to 92 years, with or without comorbidities. This report is important, as very few cases in the literature reporting death due to atypical Chikungunya virus infection are available.

We report the isolation of chikungunya virus from a patient during an outbreak of a denguelike syndrome in Cameroon in 2006. The virus was phylogenetically grouped in the Democratic Republic of the Congo cluster, indicating a continuous circulation of a genetically similar chikungunya virus population during 6 years in Central Africa.

Aedes aegypti mosquitoes are common vectors for dengue virus and chikungunya virus. In areas where both viruses cocirculate, they can be transmitted together. During a dengue outbreak in Delhi in 2006, 17 of 69 serum samples were positive for chikungunya virus by reverse transcription-PCR; 6 samples were positive for both viruses.

A disease outbreak with dengue-like symptoms was reported in Guangdong Province, China, in October 2010. Testing results confirmed that the pathogen causing the outbreak was chikungunya virus. Phylogenic analysis indicated that this virus was a member of the Indian Ocean clade of the East/Center/South African subgroup of chikungunya virus.

To the Editor: To get ready for the spread of chikungunya, health authorities in North, South, and Central America and the Pacific Islands are developing preparedness and response plans (1,2) that contain vector control, epidemiologic surveillance, medical education, and communication components. They might consider the experience of Réunion Island, an overseas department of France, where a chi...
