Conclusion: This article provides practical suggestions for strengthening the dengue virus control programme in Nigeria. TheNigerian health system shares similarities with health systems in many other sub-Saharan countries. Therefore, the practical suggestionsprovided at the end of this review are likely to be applicable to many other African countries.Keywords: Dengue fever update, Nigeria, review.

o RCP Abstract Several arboviruses have emerged and/or re-emerged in North, Central and South-American countries. Viruses from some regions of Africa and Asia, such as the Zika and Chikungunya virus have been introduced in new continents causing major public health problems. The aim of this study was to investigate the presence of RNA from Zika, Dengue and Chikungunya viruses in symptomatic patients from Rondonia, where the epidemiological profile is still little known, by one-step real-time RT-PCR. The main clinical signs and symtoms were fever (51.2%), headache (78%), chills (6.1%), pruritus (12.2%), exanthema (...

Even in this scenario, studies on the morphology of mosquito eggs are still lacking. In this paper, X-ray microtomography was used to study mosquito egg morphology. Sev...

Conclusions: The results showed that the network topology exhibits the features of a scale-free network instead of a random network. Focal hubs are highlighted and the critical period is found. Outcomes are important for the researchers, health officials, and policy makers who deal with arbovirus epidemic diseases. Zika virus and Chikungunya virus can also be modelled and analyzed in this manner. PMID: 31406610 [PubMed]

This 25-minute video features live responses from an expert to questions about dengue, which is transmitted through Aedes aegypti and Aedes Albopictus mosquitoes, also known as Asian tiger mosquitoes. These are the same mosquitoes that transmit chikungunya, yellow fever, and Zika. Topics include identifying the warning signs and symptoms of severe dengue, and complications caused by dengue.

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...

Resumo O Aedes aegypti é um importante agente transmissor de afecções na atualidade, sendo o responsável por enfermidades como Zika, Chikungunya e os quatro sorotipos do Dengue. Por ocasião da relevância desse mosquito para o corpo social atual, investigações em Ecossaúde se tornam prementes, já que essa abordag em visa articular diferentes campos teóricos para entender as conexões históricas entre a natureza, a sociedade e a saúde. Partindo de uma premissa etnográfica, este estudo considerou as condições d...

Discussion Dengue is an important arboviral infection that affects about 40% of the world population. It is found mainly in topical and subtropical areas of the world mainly in developing countries but it range is spreading including the United States. A review of common arboviruses can be found here. It is a flaviavirus with 4 distinct serotypes named DENV-1 through DENV-4 and is spread by A. aegypti a day biting mosquito. Infection with one serotype confers immunity to that serotype but not the others. It does offer some protection for cross-infection but this only lasts a few months. Incubation period is 3-14 days with ...

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.
