The Zika epidemic in Cuba, reflected by imported cases in Barcelona

(Barcelona Institute for Global Health (ISGlobal)) Travelers returning to Barcelona mirrored the 2017 Zika outbreak in Cuba, according to a study led by the Hospital Cl í nic of Barcelona and the Barcelona Institute for Global Health, an institution supported by 'la Caixa'.

Climate change is the greatest health challenge of the 21st century, and threatens all aspects of society, says the WHO in its COP24 Special Report. What could digital health technologies do to support the fight against the climate crisis? How could healthcare processes, facilities, medical devices become more sustainable? As it is humanity’s priority to mitigate the worsening as well as the impact of rising temperatures and extreme weather events, we tried to figure out what role digital health could assume here. We found many options – and even more possibilities for future development. The climate crisis...

AbstractPerceptions of infectious diseases are important predictors of whether people engage in disease ‐specific preventive behaviors. Having accurate beliefs about a given infectious disease has been found to be a necessary condition for engaging in appropriate preventive behaviors during an infectious disease outbreak, while endorsing conspiracy beliefs can inhibit preventive behaviors. Despite t heir seemingly opposing natures, knowledge and conspiracy beliefs may share some of the same psychological motivations, including a relationship with perceived risk and self‐efficacy (i.e., control). The 2015–2016 Zik...

The recent Zika virus (ZIKV) epidemic in the Americas and the Caribbean revealed a new deadly strain of the mosquito-borne virus, which has never been associated with previous outbreaks in Asia. For the first time, widespread ZIKV infection was shown to cause microcephaly and death of newborns, which was most likely due to the mutation acquired during the large outbreak recorded in French Polynesia in 2013-2014. Productive ZIKV replication and persistence has been demonstrated in placenta and fetal brains. Possible association between ZIKV and microcephaly and fetal death has been confirmed using immunocompetent mouse mode...

Recent large epidemics and epizootics and exponential increases in the numbers of YF cases in humans and non-human primates highlight the increasing threat YFV poses, despite the availability of an effective YFV vaccine. YFV is the first human virus discovered, but the structures of several of the viral proteins remain poorly understood. Here we report the structure ...

by Spencer J. Fox, Steven E. Bellan, T. Alex Perkins, Michael A. Johansson, Lauren Ancel Meyers As emerging and re-emerging infectious arboviruses like dengue, chikungunya, and Zika threaten new populations worldwide, officials scramble to assess local severity and transmissibility, with little to no epidemiological history to draw upon. Indirect estimates of risk from vector habitat suitabi lity maps are prone to great uncertainty, while direct estimates from epidemiological data are only possible after cases accumulate and, given environmental constraints on arbovirus transmission, cannot be widely generalized beyond th...

Abstract Yellow fever virus (YFV) is responsible for devastating outbreaks of Yellow fever (YF) in humans and is associated with high mortality rates. Recent large epidemics and epizootics and exponential increases in the numbers of YF cases in humans and non-human primates highlight the increasing threat YFV poses, despite the availability of an effective YFV vaccine. YFV is the first human virus discovered, but the structures of several of the viral proteins remain poorly understood. Here we report the structure of the full-length NS5 protein, a key enzyme for the replication of flaviviruses that contains both a...

Authors: Guagliardo SAJ, Ardila Roldan SC, Santacoloma L, Luna C, Cordovez Alvarez JM, Rojas Gacha JD, Mansur M, Levine RS, Lenhart A, Oviedo PF Abstract In the wake of the Zika epidemic, there has been intensified interest in the surveillance and control of the arbovirus vectors Aedes aegypti and Aedes albopictus, yet many existing surveillance systems could benefit from improvements. Vector control programs are often directed by national governments, but are carried out at the local level, resulting in the discounting of spatial heterogeneities in ecology and epidemiology. Furthermore, entomological and epidemiol...

Conclusion We found no differences in pregnancy or neonatal outcomes between women who tested positive and presumed positive for Zika virus during pregnancy. Testing of infants and placenta tissue after delivery was largely inconclusive. Improvement in testing for Zika virus infection is needed to determine which pregnancies are at risk for congenital anomalies. Further research is still needed to determine which children are at risk for poor neurodevelopmental outcomes related to Zika virus and how to best coordinate care among the immigrant population during a new disease epidemic.
