as the virus spreads through countries insouth america, health officials are growing increasingly worried about its rapid growth.they say that the u.s. could be hit hard as 24 countries worldwide are seeing it spreadat an extremely alarming rate. it's the zika virus, and there is no cure. today video was requested by the followingsubscribers. if you have any other topics you'd like to learn about, subscribe and letus know in the comments section below. zika is a mosquito-borne virus transmittedby the aedes mosquito. it was first discovered in 1947 by researchers in uganda that werestudying yellow fever. during the study, they noticed one particular monkey was sufferingfrom a different type of fever and by 1952,
they determined it was the zika virus. thegroup also discovered that the virus was transmitted by mosquitos via the blood. it wasn’t until2007, however, that any major outbreaks occurred. but even then, while there were about 49 caseson the island of yap, no one was killed or even hospitalized. major outbreaks began occurring in brazilin 2015. soon after, the virus started spreading all over south and central american countriessuch as brazil, bolivia, venezuela, haiti, barbados, the virgin islands, honduras, andmexico. the virus has recently made its way to the united states as well, but only bytravelers coming from the aforementioned places. with the outbreak came the spread of the zikafever, which is similar to the yellow fever,
west nile viruses, and dengue fever. it causesrashes and fevers along with other symptoms including pinkeye and arthritis. these symptomsdo not last very long, usually a week or less. however, health officials have recently discovereda possible connection between the fever and microcephaly; a dangerous neurodevelopmentaldisorder in babies resulting in a small, undeveloped brain that leads to seizures, motor functiondisturbances, and severe physiological effects throughout the body. in the past two months alone, brazil hasseen nearly 5,000 babies born with zika-induced microcephaly, 51 of which have died. thereis currently no vaccine available to treat the zika virus, so health officials recommendnot traveling to countries where outbreaks
have occurred. some have even gone so faras to suggest that people delay pregnancies for the next two years while experts attemptto create a vaccine. additionally, health officials have been sprayingpesticides to try to control the mosquito populations. they've also enlisted the helpof the public by asking them to liminate all standing water that attracts mosquitoes, particularlyin buckets and flower pots. while these efforts have done little to curtailthe spread of the virus, some scientists believe the solution may lie in a genetically modifiedmosquito. according to cnn, a british company called oxitec created a mutant aedes mosquitowhose purpose is to pass along a gene that kills its offspring. the idea is that sinceeach female mosquito mates only once in their
lifetime, it will be an effective way to slowthe growth of these particular mosquito populations. find out more about things in nature that'llkill you by subscribing or clicking on one of the links below.
