A Zika vaccine could save suffering and costs

(CUNY Graduate School of Public Health and Health Policy) A new study led by researchers at the CUNY Graduate School of Public Health and Health Policy (CUNY SPH) and the National School of Tropical Medicine at Baylor College of Medicine found that routinely giving the Zika vaccine to women of childbearing age could save money if the risk of Zika is around that of other mosquito-borne diseases like dengue and chikungunya.

any Usutu virus (USUV), a mosquito-borne zoonotic flavivirus discovered in South Africa in 1959, has spread to many European countries over the last 20 years. The virus is currently a major concern for animal health due to its expanding host range and the growing number of avian mass mortality events. Although human infections with USUV are often asymptomatic, they are occasionally accompanied by neurological complications reminiscent of those due to West Nile virus (another flavivirus closely related to USUV). Whilst USUV actually appears less threatening than some other emergent arboviruses, the lessons learned from ...

Further SAR on the (phenylsulfonyl)piperazine scaffold as inhibitors of the Aedes aegypti Kir1 (AeKir) channel and larvicides. ChemMedChem. 2020 Sep 14;: Authors: Aretz C, Kharade SV, Chronister K, Trigueros RR, Rodriguez EM, Piermarini PM, Denton JS, Hopkins CR Abstract Zika virus (ZIKV), dengue fever (DENV) and chikungunya (CHIKV) are arboviruses that are spread to humans from the bite of an infected adult female  Aedes aegypti  mosquito. As there are no effective vaccines or therapeutics for these diseases, the primary strategy for controlling the spread of these viruses is to p...

In the last decades, a number of infectious viruses have emerged from wildlife or re-emerged, generating serious threats to the global health and to the economy worldwide. Ebola and Marburg hemorrhagic fevers, Lassa fever, Dengue fever, Yellow fever, West Nile fever, Zika, and Chikungunya vector-borne diseases, Swine flu, Severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and the recent Coronavirus disease 2019 (COVID-19) are examples of zoonoses that have spread throughout the globe with such a significant impact on public health that the scientific community has been called for a rapid int...

ila S. Espindola The number of documented dengue cases has increased dramatically in recent years due to transmission through the Aedes aegypti mosquito bite. Vector control remains the most effective measure to protect against this and other arboviral diseases including Zika, chikungunya and (urban) yellow fever, with an established vaccine only available for yellow fever. Although the quinone class shows potential as leading compounds for larvicide development, limited information restricts the development of optimized structures and/or formulations. Thus, in this contribution we investigated the larvicidal and pupic...

pes Vieira The mosquito species Aedes aegypti is one of the main vectors of arboviruses, including dengue, Zika and chikungunya. Considering the deficiency or absence of vaccines to prevent these diseases, vector control remains an important strategy. The use of plant natural product-based insecticides constitutes an alternative to chemical insecticides as they are degraded more easily and are less harmful to the environment, not to mention their lower toxicity to non-target insects. This review details plant species and their secondary metabolites that have demonstrated insecticidal properties (ovicidal, larvicidal...

Chikungunya virus (CHIKV) is an arthropod-borne virus (arbovirus) of epidemic concern, transmitted by Aedes ssp. mosquitoes, and is the etiologic agent of a febrile and incapacitating arthritogenic illness responsible for millions of human cases worldwide. After major outbreaks starting in 2004, CHIKV spread to subtropical areas and western hemisphere coming from sub-Saharan Africa, South East Asia, and the Indian subcontinent. Even though CHIKV disease is self-limiting and non-lethal, more than 30% of the infected individuals will develop chronic disease with persistent severe joint pain, tenosynovitis, and incapacitating...

On 15 April 2020, WHO received information regarding a confirmed case of yellow fever in Magandi village, Tchibanga city in Nyanga Province of southern Gabon, 590 km from the capital, Libreville. The case is an 83-year-old male with no known vaccination history for yellow fever. He had onset of symptoms on 30 January 2020 and presented to a health facility on 2 February 2020 with abdominal pain and jaundice. Between 2 February and 9 April, he consulted the Urban Health Centre in Tchibanga, the Christian Alliance Hospital in Bongolo and the University hospital in the capital Libreville where the case received anti-malarial ...

n Chu Over the course of the last 50 years, the emergence of several arboviruses have resulted in countless outbreaks globally. With a high proportion of infections occurring in tropical and subtropical regions where arthropods tend to be abundant, Asia in particular is a region that is heavily affected by arboviral diseases caused by dengue, Japanese encephalitis, West Nile, Zika, and chikungunya viruses. Major gaps in protection against the most significant emerging arboviruses remains as there are currently no antivirals available, and vaccines are only available for some. A potential source of antiviral compounds c...

Abstract Tropical infectious diseases cause millions of deaths every year in developing countries with about half of the world population living at risk. Mayaro virus (MAYV) is an emerging arbovirus that causes Mayaro fever, which is characterized by fever, headache, diarrhea, arthralgia and rash. These symptoms can be clinically indistinguishable from other arboviruses, such as Dengue, Zika and Chikungunya, which makes the diagnosis and treatment of the disease more difficult. Though, Mayaro virus is a potential candidate to cause large-scale epidemics on the scale of ZIKV and CHIKV. Despite this, there is no lic...
