The recent outbreaks of Chikungunya (CHIK-V) virus in endemic areas of dengue (DEN-V) could increase the risk of co-infection. CHIK infection has been considered not severe and with very unusual mortality, however DEN is associated with severe manifestations and increased mortality. Little is known about coinfection. It is possible that co-infection could generate severe cases. We present a case report of co-infection DEN-V -3 and CHIK-V in an elderly patient who developed acute renal failure, dengue shock syndrome (DSS), progresses to multiple organ failure and died...

BACKGROUND: During the years 2014 and 2015, the Region of the Americas underwent a devastating epidemic of chikungunya virus (CHIKV) of the Asian genotype, resulting in millions of affected individuals. However, epidemiological and clinical information on this experience is scarce. Prior knowledge of congenital and neonatal illness caused by CHIKV is limited and almost exclusively based on data obtained from a single outbreak of the East/Central/South African (ECSA) genotype. The effect of chikungunya fever (CHIKF) on pregnancy outcomes and its consequences for infants born to infected mothers at the peak of the epidemic wave in Latin America are reviewed herein...

Dengue is a mosquito-borne viral infection that can evolve from subclinical to severe forms of disease. Early recognition during initial primary and secondary infections correlates with a reduced case-fatality rate in susceptible groups. The aim of this study was to standardize a DNA hybridization assay based on the Luminex technology for detecting and serotyping dengue virus (DENV). Reference DENVs representing the four different serotypes were used as controls to standardize the test. For validation, 16 DENV isolates obtained from a reference laboratory were analyzed in a double-blind manner to validate the test...

Chikungunya fever is an acute febrile illness caused by the chikungunya virus (CHIKV), which is transmitted to humans by Aedes mosquitoes. Although chikungunya fever is rarely fatal, patients can experience debilitating symptoms that last from months to years. Here we comprehensively assess the global distribution of chikungunya and produce high-resolution maps, using an established modelling framework that combines a comprehensive occurrence database with bespoke environmental correlates, including up-to-date Aedes distribution maps...

BACKGROUND: During December 2013, the first locally transmitted chikungunya virus (CHIKV) infections in the Americas were reported in the Caribbean. Although CHIKV infection is rarely fatal, risk for severe disease increases with age and medical comorbidities. Herein we describe characteristics of Veterans Health Administration (VHA) patients with CHIKV infection and, among those with infections diagnosed in Puerto Rico, investigated risk factors for hospitalization. METHODOLOGY: We queried VHA's national electronic medical records to identify patients with CHIKV testing during 2014...

Although Chikungunya infection is emerging as an important public health problem in many countries, it is not regarded as a life-threatening disease. Information dealing with fatal cases is scarce. We herein describe three patients with Chickungunya infection who presented with multiple organ failure and died within 24h of admission. Two cases had positive anti-dengue IgM, but dengue coinfection was rejected based on the clinical features and results of real-time reverse transcription polymerase chain reaction...

BACKGROUND: Chikungunya is a debilitating, non-fatal, mosquito borne viral fever caused by Chikungunya virus (CHIVA). The disease is transmitted to humans by the bite of Aedes aegypti and Aedes albopictus mosquitoes. Severe outbreaks of Chikungunya have been reported in several countries of Africa and Asia. Chikungunya fever is characterized by fever with sudden onset, arthralgia, rash, headache and myalgia. However, arthralgia is painful and long-lasting, affecting primarily the peripheral joints...

Chikungunya virus (CHIKV) is the only causative agent of CHIKV fever with persistent arthralgia, and in some cases may lead to neurological complications which can be highly fatal, therefore it poses severe health issues in many parts of the world. CHIKV transmission can be mediated via the Aedes albopictus mosquito; however, very little is currently known about the involvement of mosquito cellular factors during CHIKV-infection within the mosquito cells. Unravelling the neglected aspects of mosquito proteome changes in CHIKV-infected mosquito cells may increase our understanding on the differences in the host factors between arthropod and mammalian cells for successful replication of CHIKV...

BACKGROUND: Concurrent infection with two agents can result in an illness having overlapping symptoms creating a diagnostic dilemma for the treating physician. The symptoms of dengue may mimic other diseases such as leptospirosis, influenza A, Salmonella Typhi, Japanese encephalitis, chikungunya and malaria. There is paucity of data regarding dengue and typhoid co- infection both in the developed and developing countries. This study attempts to find the current co- infection rates in North Delhi...

Lassa fever (LF) is a severe viral hemorrhagic fever caused by Lassa virus (LASV). The LF program at the Kenema Government Hospital (KGH) in Eastern Sierra Leone currently provides diagnostic services and clinical care for more than 500 suspected LF cases per year. Nearly two-thirds of suspected LF patients presenting to the LF Ward test negative for either LASV antigen or anti-LASV immunoglobulin M (IgM), and therefore are considered to have a non-Lassa febrile illness (NLFI). The NLFI patients in this study were generally severely ill, which accounts for their high case fatality rate of 36%...

Chikungunya virus (CHIKV), a mosquito-borne alphavirus, recently re-emerged in Africa and spread to islands in the Indian Ocean, the Indian subcontinent, and to South East Asia. Viremic travelers have also imported CHIKV to the Western hemisphere highlighting the importance of CHIKV in public health. In addition to the great burden of arthralgic disease, which can persist for months or years, epidemiologic studies have estimated case-fatality rates of ∼0.1%, principally from neurologic disease in older patients...

Chikungunya virus (CHIKV) is an alphavirus transmitted to humans through the bite of infected Aedes mosquitoes. CHIKV causes fever and usually is not fatal, but can cause debilitating joint pains or, in rare instances, severe illness. The East/Central/South African strain of chikungunya has been emerging in Asia since 2006, first in the Indian subcontinent, then Thailand. This report describes the characteristics of a local outbreak linked with chikungunya reemergence in a rural Asian setting. Sporadic cases of chikungunya were identified in Cambodia in 2011...

INTRODUCTION: The largest chikungunya epidemic in history hit Reunion Island in 2005/6. At that time, a specific monitoring system was set up. Since the end of the epidemic, this monitoring system has continued to operate and has been enhanced. The main objectives of the system are early detection of any case of chikungunya virus infection and epidemiological monitoring. METHODS: During nonepidemic periods, surveillance is focused on active detection of all cases...

Chikungunya virus (CHIKV) infection causes a disease which appears to affect multiple cell types and tissues. The acute phase is manifested by a non-fatal febrile illness, polyarthralgia and maculopapular rashes in adults, but with recurrent arthralgia that may linger for months during convalescence. The issue of cellular and tissue tropism of CHIKV has elicited interest primarily because of this lingering incapacitating chronic joint pain, as well as clear encephalopathy in severe cases among neonates during the re-emergence of the virus in recent epidemics...
