First native Zika cases in Europe confirmed as experts warn climate change could bring more

The first native cases of Zika in Europe have been confirmed after three people became infected with the virus in France. Experts warn that climate change could lead to more cases emerging across the continent.

(University of Saskatchewan) Using a relevant animal model (pigs), University of Saskatchewan researchers have shown that mild Zika virus infection in fetuses can cause abnormal brain development in apparently healthy young animals. The study, published Nov. 14, 2019 in PLOS Pathogens, provides new insights into the potential outcomes of Zika virus infection and could point to new prevention and treatment strategies to alleviate the long-term effects of Zika virus infection.

Lu Lu Recently, Zika virus (ZIKV) has attracted much attention in consideration of its association with severe neurological complications including fetal microcephaly. However, there are currently no prophylactic vaccines or therapeutic drugs approved for clinical treatments of ZIKV infection. To determine the potential anti-ZIKV inhibitors, we screened a library of clinical drugs with good safety profiles. Erythromycin estolate (Ery-Est), one of the macrolide antibiotics, was found to effectively inhibit ZIKV infection in different cell types and significantly protect A129 mice from ZIKV-associated neurological sign...

ABSTRACTAedes aegyptiandAedes albopictusare invasive mosquito species with geographic ranges that have oscillated within Florida since their presence was first documented. Local transmission of dengue, chikungunya, and Zika viruses serves as evidence of the public health importance of these two species. It is important to have detailed knowledge of their distribution to aid in mosquito control efforts and understand the risk of arbovirus transmission to humans. Through a partnership involving the University of Florida Institute of Food and Agricultural Sciences Cooperative Extension Service and the Florida Medical Entomolo...

Authors: Maniero VC, Rangel PSC, Coelho LMC, Silva CSB, Aguiar RS, Lamas CC, Cardozo SV Abstract A progressive increase in the circulation of arboviruses in tropical countries has been observed, accounting for 700,000 yearly deaths in the world. The main objective of this article was to identify the presence of Zika (ZIKV), dengue (DENV), and Chikungunya (CHIKV) viruses in immature stages of Aedes aegypti and Ae. albopictus. Household collections of immature phases of the vectors were carried out in the years 2015 and 2016. A total of 2902 dwellings were visited and the rate of infestation with larvae and pupae of ...

Chow, Shirley Luckhart, Alan G. GoodmanSummaryThe World Health Organization estimates that more than half of the world’s population is at risk for vector-borne diseases, including arboviruses. Because many arboviruses are mosquito borne, investigation of the insect immune response will help identify targets to reduce the spread of arboviruses. Here, we use a genetic screening approach to identify an insulin-like receptor as a...
