Authors: Foresto RD, Santos DWCL, Hazin MAA, Leyton ATZ, Tenório NC, Viana LA, Cristelli MP, Silva Júnior HT, Pestana JOM Abstract In 2004, a global spread of Chikungunya fever affected most tropical and subtropical regions of the world. In 2016, an outbreak occurred in Northeast Brazil with hundreds of cases documented. Solid organ transplant recipients have a modified immune response to infection and the clinical course is usually different from immunocompetent patients. The diagnosis can be challenging in this population. Most reports describe patients residing in endemic areas, although we must em...

CONCLUSION: This study identified an asymptomatic ZIKV infection in a blood donor occurring before those previously recognized by blood donation screening. NAT and PR continue to be used as acceptable strategies to prevent transfusion-transmitted arboviral infections worldwide; however, repeated arboviral outbreaks warrant consideration of PR as a more proactive approach.

This report summarizes surveillance data reported to CDC for 2018 on nationally notifiable arboviruses. It excludes dengue, chikungunya, and Zika viruses because they are primarily nondomestic viruses typically acquired through travel. In 2018, 48 states and the District of Columbia (DC) reported 2,813 cases of domestic arboviral disease, including 2,647 (94%) WNV disease cases. Of the WNV disease cases, 1,658 (63%) were classified as neuroinvasive disease (e.g., meningitis, encephalitis, and acute flaccid paralysis), for a national incidence of 0.51 cases of WNV neuroinvasive disease per 100,000 population. Because arbovi...

Abstract Chikungunya is a viral disease caused by chikungunya virus (CHIKV) belonging to the Alphavirus genus and transmitted to humans by mosquitoes of Aedes spp. Nearly 40 countries in Asia, Africa, Europe, and the Americas have documented chikungunya cases. Most recent severe outbreaks have occurred in Indian Ocean islands of Réunion and Mauritius and India. There is no specific drug treatment for the disease, neither is there a standardized vaccine available for prevention of the disease. The present review gives a global perspective on patents filed pertaining to chikungunya. The United States has been...

e;nez Ana M. Rivas-Estilla Chikungunya virus (CHIKV) is a mosquito-borne alphavirus that causes Chikungunya fever. CHIKV entered Mexico through the state of Chiapas in October 2014. To fully understand the Chikungunya fever outbreak that occurred in southern Chiapas during 2015, we evaluated 22 PCR-confirmed CHIKV-positive patients, identified CHIKV genetic variability, reconstructed viral dispersal, and assessed possible viral mutations. Viruses were isolated and E2, 6K, and E1 genes were sequenced. We applied phylogenetic and phylogeographic approaches, modeled mutations, and estimated selective pressure. Different...

Abstract The Mayaro virus disease (MAYVD) is an emerging mosquito borne zoonosis that was first reported on the island of Trinidad in 1954. The viral agent for this disease is known to presently be endemic to Central and South America. The enzootic cycle of the Mayaro virus (MAYV) is not fully characterized, though primates are thought to be the main reservoir with Haemagogus species of mosquitoes as the primary vector. This virus has been responsible for several sporadic cases of infections and limited outbreaks, but it is postulated that the MAYVD will become a major epidemic in the future, following in the step...

ConclusionsThese findings indicate that AGO traps are an effective tool that protects humans from infection with a virus transmitted byAe.aegypti mosquitos. Future studies should evaluate their protective effectiveness in large, urban communities.

In this study, we estimate the direct medical costs, cost of lost wages due to absenteeism, and years lived with disability (YLD) associated with the 2014–2015 CHIKV outbreak in the U.S. Virgin Islands (USVI). For this analysis, we used surveillance data from the USVI Department of Health, medical cost data from three public hospitals in USVI, and data from two studies of laboratory-positive cases up to 12 months post illness. On average, employed case-patients missed 9 days of work in the 12 months following their disease onset, which resulted in an estimated cost of $15.5 million. Estimated direct healthcare costs ...

The present study shows that the most prominent human arboviruses worldwide (dengue viruses 1, 2, 3, and 4, Chikungunya virus, and Zika virus) can infect wild animals and jump from urban to sylvatic maintenance cycles in South America, as did the yellow fever virus in the past. All these viruses are transmitted by the anthropophilic mosquito Aedes aegypti and cause epidemics throughout Brazil. The yellow fever virus is the oldest example of an urban arbovirus that became sylvatic in South America. Currently, the disease is a zoonosis of non-human primates that moves like a wave through forests of the Brazilian countryside,...
