hard J.P. Brown Yellow fever virus (YFV) represents a re-emerging zoonotic pathogen, transmitted by mosquito vectors to humans from primate reservoirs. Sporadic outbreaks of YFV occur in endemic tropical regions, causing a viral hemorrhagic fever (VHF) associated with high mortality rates. Despite a highly effective vaccine, no antiviral treatments currently exist. Therefore, YFV represents a neglected tropical disease and is chronically understudied, with many aspects of YFV biology incompletely defined including host range, host–virus interactions and correlates of host immunity and pathogenicity. In this a...

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,...

Emerging infectious diseases (EID) and reemerging infectious diseases are increasing globally. Zoonotic diseases are transmitted from animals to humans through direct contact or through food, water, and the environment. Vector-borne diseases are major sources of mortality and morbidity globally. Three mosquito-borne viruses are yellow fever, chikungunya virus, and dengue virus. Recent EIDs include Candida auris, Elizabethkingia anopheles, The Lone Star tick, and avian influenza H7N2. In addition, mcr-1 may contribute to the dissemination of drug resistance to gram-negative bacteria. Nurses play a major role in the identifi...

Johansen, Jody Hobson-Peters, Roy A. Hall, Andrew F. van den Hurk Arthropod-borne flaviviruses such as yellow fever (YFV), Zika and dengue viruses continue to cause significant human disease globally. These viruses are transmitted by mosquitoes when a female imbibes an infected blood-meal from a viremic vertebrate host and expectorates the virus into a subsequen t host. Bamaga virus (BgV) is a flavivirus recently discovered inCulex sitiens subgr...

Background: Yellow Fever (YF), a zoonotic disease transmitted by mosquito to human remains a global health threat. The virus is more common in the tropical regions of sub-Saharan Africa and South America where it accounts for no fewer than 50,000 deaths annually. Vaccination is the most effective means of preventing the infection as there is currently no cure for the disease. Of the two regions which are highly endemic for YF transmission, the sub-Saharan Africa has the highest rates of infection.

AbstractPurpose of reviewArthropod-borne viruses (arboviruses) are zoonotic, and the common vectors are ticks and hematophagous mosquitoes. Currently, dengue, chikungunya, yellow fever, West Nile, and Japanese encephalitis virus infections have been causing worldwide concerns. In 2015, a large outbreak was documented with another mosquito-borne flavivirus, the Zika virus (ZIKV), and ravaging South and Central Americas and the Caribbean. ZIKV was declaring a public health emergency, because of the clinical evidence neurological complications.Recent findingsThe flavivirus infection is difficult to differentiate only with cli...

opoulou Oropouche fever is an emerging zoonotic disease caused by Oropouche virus (OROV), an arthropod transmitted Orthobunyavirus circulating in South and Central America. During the last 60 years, more than 30 epidemics and over half a million clinical cases attributed to OROV infection have been reported in Brazil, Peru, Panama, Trinidad and Tobago. OROV fever is considered the second most frequent arboviral febrile disease in Brazil after dengue fever. OROV is transmitted through both urban and sylvatic transmission cycles, with the primary vector in the urban cycle being the anthropophilic biting midge Culicoides ...
