Title : Insect Repellants During Pregnancy in the Era of the Zika Virus Personal Author(s) : Wylie, Blair J.;Hauptman, Marissa;Woolf, Alan D.;Goldman, Rose H. (cdc.gov)
Zika virus ( ZIKV ) is an important re-emerging flavivirus that presents a significant threat to human health worldwide. (bvsalud.org)
Zika virus disease is caused by the Zika virus, which is spread to people primarily through the bite of an infected mosquito ( Aedes aegypti and Aedes albopictus ). (cdc.gov)
However, Zika virus infection during pregnancy can cause a serious birth defect called microcephaly and other severe brain defects. (cdc.gov)
however, only a small proportion of people with recent Zika virus infection get GBS. (cdc.gov)
Q: What are the symptoms of Zika virus disease? (cdc.gov)
The most common symptoms of Zika virus are headache, muscle and joint pain, mild fever, rash, and inflammation of the underside of the eyelid. (who.int)
CDC has developed interim guidelines for health care providers in the United States caring for pregnant women during a Zika virus outbreak. (cdc.gov)
These guidelines include recommendations for pregnant women considering travel to an area with Zika virus transmission and recommendations for screening, testing, and management of pregnant returning travelers. (cdc.gov)
Updates on areas with ongoing Zika virus transmission are available online ( http://wwwnc.cdc.gov/travel/notices/ ). (cdc.gov)
Pregnant women with a history of travel to an area with Zika virus transmission and who report two or more symptoms consistent with Zika virus disease (acute onset of fever, maculopapular rash, arthralgia, or conjunctivitis) during or within 2 weeks of travel, or who have ultrasound findings of fetal microcephaly or intracranial calcifications, should be tested for Zika virus infection in consultation with their state or local health department. (cdc.gov)
Testing is not indicated for women without a travel history to an area with Zika virus transmission. (cdc.gov)
In pregnant women with laboratory evidence of Zika virus infection, serial ultrasound examination should be considered to monitor fetal growth and anatomy and referral to a maternal-fetal medicine or infectious disease specialist with expertise in pregnancy management is recommended. (cdc.gov)

While only found within this small population, the virus causes severe harm to occur to infected larvae and can even cause death. (wikipedia.org)
Orthopteran insects have high reproductive rates leading to boom-bust population dynamics with high local densities that are ideal for short, episodic disease epidemics. (mdpi.com)

The first ISV identified is cell-fusing agent virus (CFAV), which was isolated from an Aedes aegypti ( Ae . (encyclopedia.pub)

We speculate that the temperate replication style exists, in part, to promote virus dispersal, to allow viruses to reach new environments where they can flourish," said Dr. Bushman. (sciencedaily.com)

While the carrier wasp is completely asymptomatic, the infected caterpillar displays AIDS-like sym ptoms, whereby its ability to mount an immune response against the wasp egg or larva is depressed by the virus. (esc-sec.ca)

Testing by Enzyme Linked Immunosorbent Assay (ELISA) for six potato viruses identified five viruses: potato leafroll virus (PLRV), potato virus X, S, M and Y (PVX, PVS, PVM, PVY) in Rwanda and two viruses (PLRV and PVS) in Burundi. (cipotato.org)

Scientists based in Beijing, China, studied how one symbiotic virus, Acyrthosiphon pisum virus (APV), actually helps its host aphid adapt to new plants. (phys.org)

However, the Defence Advanced Research Projects Agency ( Darpa ), which is responsible for developing military technologies in the US, says it is merely trying to alter crops growing in fields by using viruses to transmit genetic changes to plants. (independent.co.uk)
We will use two approaches: controlled assays which will test the direct impact of the insecticide on the physiological acquisition of the virus, and a no-choice arena to test the behavioral effects of insecticide treatments on aphid settling on potato plants, as this behavior has a strong influence on virus spread within a field.

The wasps may therefore be viewed as having 'domesticated' the nudivirus, turning it into a mutualistic virus - a phenomenon fairly unique in the world of viruses. (esc-sec.ca)
