Fact About the West Nile Zika Virus
Five facts about the Zika virus
Chances are you've come across the Zika virus on the news. With an estimated three to four million infection cases over this year, chances are you haven't heard the last of this terrible disease either. We've compiled some facts about the virus below, so please read on to know more about it.
The primary carriers are mosquitoes
Like the West Nile virus and dengue fever, the primary carrier of the Zika virus is a mosquito. In particular, the mosquito that carries Zika is of the Aedes variety—primarily the Aedes aegypti mosquito that is also the main carrier of dengue fever. The full list of vectors is not completely known, but the virus has also been isolated in a few other species of mosquito.
Humans are also carriers, as the virus can possibly be transmitted through sexual intercourse. An infected mother can also spread the virus to the fetus.
It is not a recent discovery
The Zika virus may have only filtered into the mainstream consciousness in the several months since the outbreak, but it was not discovered recently. It was first isolated by scientists in 1947, and it wasn't until 1952 that we had the first evidence of infection in a human. In Nigeria tests, 50 out of 84 people across various ages showed antibodies to the virus; in India tests, a significant number showed an immune response to the virus. These findings suggest that the virus had been widespread in humans for a long time already.
There have been previous outbreaks
The first outbreak that occurred outside of Asia and Africa was in 2007, in the island of Yap in Micronesia. In 2013-14, an outbreak also occurred in Oceania, spanning the Cook Islands, Easter Island, French Polynesia, and New Caledonia. Then we have the well-documented outbreaks in late 2015 through early 2016 in the Americas.
It causes microcephaly in newborns
This fact has only been truly confirmed recently, but now there is no more doubt that this virus will cause microcephaly in newborn babies whose mother had been infected during pregnancy. It is not yet clear whether the pregnancy stage at the time of infection affects the outcome.
No vaccines or treatment yet
At the moment, there exists no vaccine to counter this virus. Scientists are hard at work trying to come up with various solutions, though, so there should be more progress sooner rather than later.
As there is no treatment or vaccine that specifically combats the Zika virus, he general approach to infections involve drinking lots of fluids, getting a lot of rest, and using common medicines for pain and fever. Proper medical care should be sought should the symptoms get worse.
The Zika virus is definitely a big concern. In case incidents have been reported in your area, make sure you take the necessary mosquito control measures in order to avoid getting infected. Better safe than sorry, after all. We hope scientists will be able to break through and develop the vaccine that can get rid of this virus sooner rather than later.
