Mosquitoes vary in their competence or ability to transmit arthropod-borne viruses (arboviruses). Many arboviruses cause disease in humans and animals. Identifying the environmental and genetic causes of variation in mosquito competence for arboviruses is one of the great challenges in public health. Progress identifying genetic (nature) and environmental (nurture) factors influencing mosquito ...

The recent global (re)emergence of arthropod-borne viruses (arboviruses), such as chikungunya and Zika virus, was widely reported in the media as though it was a new phenomenon. This is not the case. Arboviruses and other human microbial pathogens have been (re)emerging for centuries. The major difference today is that arbovirus emergence and dispersion are more rapid and geographically extensi...

Arthropod-borne viruses (arboviruses) have a devastating impact on human health. The arbovirus of greatest medical significance is dengue virus (family Flaviviridae), which occurs in every, or almost every, country with a tropical or subtropical environment. According to one recent estimate, dengue virus is responsible for 390 million infections annually, of which 96 million are accompanied by ...

Arboviruses and arboviruses represent an ancient threat to a large part of humanity. This consists mainly in the ease that viruses their vectors have adapt, also fact RNA allows many mutations genetic recombinations. There are still no effective vaccines for such as Dengue, Chikungunya Zika virus, therefore, it is extremely important scientific community produce work on our body’s defenses agai...

Arboviruses (arthropod-borne viruses) are important emerging pathogens in many tropical and developing countries of the world. The Southeast Asian and Western Pacific regions have recently experienced large outbreaks of dengue, Japanese encephalitis and chikungunya fever. In Papua New Guinea (PNG) serological surveys and mosquito isolation experiments suggest that arboviruses are prevalent thro...

Abstract Objective: to estimate the seroprevalence of arboviruses, syphilis, HIV, and hepatitis B (HBV) in Healthcare Workers (HCW). Methods: a survey among HCW was randomly selected city Bahia-Brazil. The research used structured questionnaire, which collected sociodemographic, occupational, health information 2019. Rapid immunochromatographic tests were track infections. Thus, positive result...

Arboviruses are most prevalent in tropical and subtropical regions, where arthropods widespread. The World Health Organization (WHO) estimated that the mortality burden of arbovirus diseases, such as yellow fever Africa, was 84,000–170,000 severe cases 29,000–60,000 deaths 2013. These epidemics emphasize urgent need for integrated control prevention arboviral diseases. Challenges managing contr...
