The Latest On Zika: Experts Are Divided Over Genetically Modified Mosquitos

The Zika virus, which is spread by the Aedes aegypti mosquito, is strongly suspected to be linked to a new wave of microcephaly cases in Brazil. Babies born with the birth defect have smaller heads and sometimes brains that aren't fully developed, which can result in life-long developmental problems.    Zika is currently spreading through Central and South America and the Caribbean, and with the high volume of news about the virus, it's tough to stay up-to-date. Check out our full coverage, or read our daily recaps. Here are four updates, opinions and developments to know about now:   1. Genetically modified mosquitos divide scientists and environmentalists  The World Health Organization's advisory group recommended further trials of genetically modified mosquitos to fight Zika virus. The GM mosquitos could stem Zika's spread by releasing sterile male insects, who diminish the mosquito's population when they fail to reproduce. Another potential strategy is injecting Wolbachia bacteria into the mosquitos; the bacteria doesn't affect humans, but prevents female mosquitos' eggs from hatching if they mate with an infected male mosquito. But environmentalists warn of unintended consequences: Controlling insects by genetically modifying them and eliminating an entire species of mosquitos could affect the world's delicate ecosystem in unforeseen ways.  Vector control experts disagree."This is an invasive species, so getting rid of th...

Reiner Jr., Fatima Marinho BackgroundIn 2015, high rates of microcephaly were reported in Northeast Brazil following the first South American Zika virus (ZIKV) outbreak. Reported microcephaly rates in other Zika-affected areas were significantly lower...

Abstract ZIKA virus (ZIKAV) outbreak in Latin America was associated with international concerns of ZIKAV circulation. The lack of vaccine and FDA-approved drugs against this virus rendered prevention as the single most effective method to control its spread. Hence, this study aimed to assess Jordanian population knowledge, attitude, and practices toward ZIKAV and its prevention. An anonymous questionnaire was administered to adults in Amman, Jordan. The overall knowledge of participants was poor (mean knowledge score of 13.7/32). Between 75% and 86% of the respondents did not know the highest risk group of ZIKAV ...

Source: Wellcome Trust. Published: 9/2018. This 96-page guidance provides a roadmap for the ethically responsible, socially just, and respectful inclusion of the interests of pregnant women in the development and deployment of vaccines against emerging pathogens. It discusses how recent epidemics, including Zika virus, Lassa Fever, Ebola, and H1N1 influenza, have highlighted the ways in which infectious disease outbreaks can severely affect the health interests of pregnant women and their offspring. It specifies 22 concrete recommendations, organized around three key areas: public health preparedness, R&D, and vaccine delivery. (PDF)

Joshi The recent outbreaks of Zika virus (ZIKV) infections and associated microcephaly in newborns has resulted in an unprecedented effort by researchers to target this virus. Significant advances have been made in developing vaccine candidates, treatment strategies and diagnostic assays in a relatively short period of time. Being a preventable disease, the first line of defense against ZIKV would be to vaccinate the highly susceptible target population, especially pregnant women. Along those lines, several vaccine candidates including purified inactivated virus (PIV), live attenuated virus (LAV), virus like particles ...

amond Zika virus (ZIKV) emerged suddenly in the Americas in 2015 and was associated with a widespread outbreak of microcephaly and other severe congenital abnormalities in infants born to mothers infected during pregnancy. Vertical transmission of ZIKV in humans was confirmed when viral RNA was detected in fetal and placental tissues, and this outcome has been recapitulated experimentally in animals. Unlike other flaviviruses, ZIKV is both arthropod- and sexually-transmitted, and has a broad tissue tropism in humans, including multiple tissues of the reproductive tract. The threats posed by ZIKV have prompted the devel...

Conclusion The results obtained from this research shows, in general, the fragility in the social and political infrastructure necessary to improve the living conditions of populations, particularly those that depend on family agriculture in drought prone areas. The conditions of social, economic and environmental vulnerabilities presented in the region can be amplified by the drought process, and can aggravate the impacts resulting drought events, thus disadvantaging the population of this region, as shown in the Fig. 1. The general perception of the interviewees of the health sector shows an agreement with what is found...

This study aims to describe pregnant women's attitudes toward Zika virus vaccine research participation, as well as perceived barriers to and facilitators of enrollment. METHODS: Pregnant and recently postpartum women (n = 128) attending prenatal care at Massachusetts General Hospital completed surveys querying their willingness to participate in four hypothetical Zika virus vaccine trials and their motivations for participation. Demographics, information on prior Zika virus exposure, and vaccine acceptance were collected. RESULTS: Most women (77%) accepted participation in at least one hypothetical Zika viru...

Conclusions Surveillance, risk assessment, and intervention were strengthened throughout Malaysia in response to the 2016 outbreak of ZIKV in neighboring Singapore. The Malaysian Ministry of Health undertook regular surveillance from June 2015 during the South American outbreak, but no ZIKV was detected in 784 samples tested up to August 2016 (https://kpkesihatan.com/2016/08/28/kenyataan-akhbar-kpk-28-ogos-2016-situasi-terkini-virus-zika-di-malaysia/). However, during the peak of the 2016 Singapore ZIKV outbreak from September through December 2016, eight out of 849 samples tested were positive for ZIKV (https://kpkesiha...

Authors: Soriano-Arandes A, Rivero-Calle I, Nastouli E, Espiau M, Frick MA, Alarcon A, Martinón-Torres F Abstract INTRODUCTION: Zika virus (ZIKV) infection has caused the most challenging worldwide infectious epidemic outbreak in recent months. ZIKV causes microcephaly and other congenital malformations. There is a need to perform updated systematic reviews on ZIKV infection periodically because this epidemic is bringing up new evidence with extraordinary speed. Areas covered: Evidence related to ZIKV infection in the gestational, perinatal, and early infant periods covering epidemiology, virology, pathogene...
