Zika Virus: First Insect-Borne STD

B
Let’s start at the beginning. Where did Zika come from?


Like so many emerging viruses, Zika came out of Africa. It was first isolated in 1947 from a rhesus monkey in Uganda’s Zika forest. But it did not cause significant outbreaks of human disease until 2013-14 in French Polynesia. It probably reached the Americas late in 2014, when an infected traveller was bitten by a local mosquito which then transferred the virus to other people.

What are the symptoms of Zika infection?

They are usually mild or non-existent. Most characteristic are a rash, itchy skin and red eyes. The trouble comes when pregnant women are infected. Then the virus attacks the brain of the foetus, leading to the birth of a baby with a very small head and neurological problems. Zika only began to arouse serious concern among global health experts in October, when authorities in Brazil linked it to a rapid rise in microcephaly in the country’s tropical north-east where Zika cases are concentrated.

How does Zika spread?


It is a typical mosquito-borne virus, transmitted by aedes aegypti, the species that carries several other human diseases including dengue and chikungunya. It is unclear why it has spread with explosive speed in the tropical Americas over the past year. The risk of direct transmission between people is very remote, although the virus has been isolated in semen so sexual transmission cannot be ruled out.

Does the mosquito transmission mean that some parts of the world are safe from Zika infection?

Yes. Aedes aegypti only thrives in tropical and subtropical regions. It cannot survive cold winters, so most of the US and Europe are safe — unless global warming gathers pace or the virus mutates and moves into a mosquito species that lives in temperate climates. Most Europeans and Americans are vulnerable only if they travel to an infected region; a few have already returned home with Zika symptoms.

Is it safe to travel to the tropical Americas?


The only people who should worry are women who are pregnant or planning to become pregnant. They are advised not to travel to areas with high levels of infection unless really necessary, and then to take steps to avoid mosquito bites, including covering bare skin with clothing or insect repellent and using mosquito nets.

What about the Olympics in Brazil?

It is too early to predict infection levels in and around Rio in August. The authorities hope they will be very low, both because they are working to eliminate pools of stagnant water where mosquitoes breed and because the weather then will be relatively cool and dry, and therefore less hospitable to mosquitoes.

What is longer-term outlook for the epidemic?


We do not know because serious research into Zika only began three or four months ago when scientists realised the threat posed by the virus to unborn children. The optimistic view is that people in infected regions will quickly build resistance to the virus and the outbreak will burn itself out. But that might be wishful thinking.

Any chance of a treatment or vaccine?


At the moment there is no reliable diagnostic test for Zika let alone an antiviral drug or vaccine. But research is gathering pace. GlaxoSmithKline is evaluating the possibility of using its vaccine technology for Zika, and Inovio, a US biotech company, is working on a candidate.

How about attacking the mosquitoes that carry the virus?


“Vector control” is possible by avoiding the build-up of stagnant water in populated areas and attacking mosquitoes through pesticides, although this approach cannot completely eliminate the mosquitoes. A more futuristic approach, developed by Oxitec of the UK and undergoing field trials in Brazil and elsewhere, uses genetically modified insects to wipe out the mosquitoes: large numbers of GM males are released to breed with all available females, producing offspring that die young. But this technology will not be available on a large scale in time to have much effect on the current Zika epidemic.

Blame everything of Africa, because it makes everyone feel good about
themselves... That is just how they hate Africa, but want to steal its
music, culture and resources... I am African, and never heard of this
virus, how come
 
I've been saying..

If a mosquito can transmit malaria, why not HIV?

Both are transmitted thru blood.
Several reasons why a mosquito can't transmit HIV.

Mosquito do not have T cells. HIV needs T cells to bind with in order to replicate. So basically HIV is almost immediately destroyed in the mosquitoes stomach.

Mosquito have more than one tune system the one they use to peirce the skin only injects saliva

Maybe people were getting sick and didn't have the technology to know what was causing the illness. Everything isn't a conspiracy. There are over 600 million Africans without electricity, and you think people have the resources to identify diseases?

This is really about fucking mosquitoes. The most dangerous animal known to humans.
 
Unsure why posts from my Democratic Debate thread were merged in here...but oh Wells....

If there is no technology to know these things, how do people who do not even live in Africa
know those numbers. If there are 600 million Africans without electricitiy, that mean there
are 500 million Africans with electectricity, or roughly the same number as North or South Americans
with electricity. The reason why this story is bullshit is this: the migratory patterns between Africa
and Europe are 20 times more than the migratory patterns between Africans and Americans in
either the northern or southern continent. If Africans were carrying an infectious affliction, it
would be more manifest in the Europeans we consort with all the time, than in the Americans
of either continent we seldom have contact with.

The score is all for me and zero for you

The point about technology is that people obviously have other things to worry about. You're acting like just because you haven't heard of shit it couldn't have existed. That's just crazy. There's only one fucking place in all of Uganda(where the disease was found 70 years ago) where you can test for the virus and you're argument is :eek: "I haven't heard of it?" 75 percent of people in Uganda don't have electricity, but you wonder why you haven't heard of the disease. How many people out of 40 million or so would even know they got the shit? There aren't any deaths related to it, so you really think it's a priority?

And what are you talking about migratory patterns for? This is about mosquitoes transmitting the disease. Why do you keep worrying about whether or not the disease was first discovered in Africa?

But if takes electricity to know anything, or everything as some of you seem
to think, how did a foreigner from far away, find something, where the locals
did not see anything? If you knew a little bit about Africa, you would know
that prestigious Makerere University had up and running for 25 years by
1947. There were, and are, a lot of educated Africans in Uganda, holding advanced
degrees in sciences. As a matter of fact, one of those Ugandans, a professor,
was my biology teacher in my first college year. You taking one thing you think is
negative, and extrapolating from there to make wide, wild and unsubstantiated
statements about the whole continent of Africa. If the virus was a problem
in Africa, how come microcephaly did not manifest there, but instead is
ravaging Brazil and South America and the USA?????

They make HIV, they blame Africa; they make Ebola, they blame Africa;
now they have made this, they blame Africa....

And people like you regurgitate that nonsense as if you know what you are
talking about.

always on that bullshit. of ALL the shit that came out of europe...woops they have vaccines for those
Just wait and see.... but no, apparently, the English have come up with
wonderful idea of "genetically engineering mosquitos" which will mate
with and deplete the population of mosquitos which are conveying this
virus, and in so doing forestall its spread. Of course when "these mosquitos
get to Africa, do not be surprised if they start to multiply after all"

I didn't say it takes electricity to know anything. I was just illustrating that there are bigger problems for people to be concerned with than a non-lethal virus. Damn. You the one who made the statement that since you didn't hear of the virus there must be some fucking conspiracy. I showed you why you might not have heard of it.

Refute the fact that there is only one place to test for it in Uganda. I'll wait. You worried about 25 years before 1947, what is going on now? Why does there have to be so much medical help given to Africa if business is being handled at these great universities and research centers? Just cut the shit. A disease might exist right now that is affecting a rural area and you might not know shit about it. They going to send in some goofy ass cacs to see what is what. One of these days, these goofy cacs going to accidentally unleash some crazy shit on the world by trying to deal with local diseases affecting only a handful of people in remote areas.

Also, where is the fucking proof that 'they' made any of those diseases you are referring to?

The discussion should be how to stop fucking mosquitoes so they can have the Olympics in fucking peace and you got a tin foil hat on while sitting on a pile of bean pies and giving the cac far too much credit.
 
zik-world-map_12-22-2015_web.jpg

The last time I heard, there were at least 31 cases in the USA, in
11 states, how come they are not on this map. The US is quick
to depict others as some how in a worse situation than they are;
I see a band of countries spanning Angola, Zambia, Tanzania,
Kenya Ethiopia, Somalia and Ethopia that are being implicated.
They attribute this implication to a "sero-survey" meaning, they drew
blood but found nothing; and they are painted with crossed purple;
and yet some how, the US in which the have drawn blood and found
something is left clean and clear...

I was out living my life, so before you start doing little celebratory dances, know
that I just did not have the time to answer this drivel. You cannot disavow your
constant allusion to the so-called 'absence of electricity'. Whenever I presented
the objective facts, that was your only response, until I pointed out that by there
are more people in Africa with electricity than there are in North America or
Western Europe.....

Secondly, diseases are tested for in hopitals and clinics; and Uganda has
thousands of them. The science used in those facilities is exactly the same
science used in American and European facitilites.

Whether there is one, or there are many facilities in Uganda, equipped to test
for the Zika virus, it remains the fact that a foreigner arriving in Uganda, was
hampered by the presence of only one such testing facility, or aided by the
many, in his so-called discovery of this virus there; which behooves us to ask,
why if this virus was always there, the local scientists using that one, or the many
facilities, never discovered it...do not tell me it is because 600 million Africans
lack electricity

Let it also be added that just because a virus in seen in one place first, does not
mean it originally started there. The virus could have been a native of Brazil
and have been transported to Uganda. It could have been a developed in an
American lab and transported to whoever they hated the most and deposited
there.

It is not your place, or in your exclusive ability, to be able to divine where this
came from. But I can tell you very explicitly that microcephaly is not and has
not been an African problem. I am an African, and I stay informed about my
homeland. You on the other hand, evidently, know little to nothing about it.
