Zika Virus – What You Need to Know

Sharing is caring!

Zika virus has started making headlines recently. The first I saw of it was an article titled “El Salvador urges against pregnancies until 2018 as Zika virus spreads“, which caught my attention, since no babies for two years is a pretty drastic step. Predictably, there are now those offering “Zika virus protection products”, as well as a Zika virus vaccine in the works (but likely not available for widespread use soon).

Zika virus has been implicated in potentially deadly birth defects. Learn where it came from, how it is transmitted, symptoms and treatment.

Since I had never heard of this virus before, I figure others might not have heard of it, either, so I figured I'd cover the basics of Zika virus and Zika disease so we have a working knowledge of the problem. If something is dangerous enough to have countries talking about banning babies, it deserves attention, and if there are other factors involved, they should be known, too.

What is Zika virus?

From the World Health Organization:

Zika, a flavivirus transmitted mainly by mosquitos in the genus Aedes, was discovered in 1947 in Uganda. From the 1960s to 1980s, human infections were found across Africa and Asia, typically accompanied by mild illness. The first large outbreak of disease caused by Zika infection was reported from the Island of Yap (Federated States of Micronesia) in 2007, as the virus moved from south-east Asia across the Pacific.

The fact sheet also mentions the similarities between zika virus and dengue fever:

Under-reporting may also be a reason for missing previous outbreaks of infection, due to the clinical similarities of (mild) illness associated with Zika, dengue, and chikungunya infections, and the frequent co-circulation of all three viruses.

How do you catch Zika virus?

Zika virus is almost always spread through Aedes aegypti mosquito bites. WHO also notes that some evidence suggests Zika virus can also be transmitted to humans through blood transfusion, perinatal transmission and sexual transmission; however, these modes are very rare.

What are the symptoms of Zika Virus?

From the WHO:

Zika virus infection is characterized by low grade fever (less than 38.5°C) frequently accompanied by a maculopapular rash. Other common symptoms include muscle pain, joint pain with possible swelling (notably of the small joints of the hands and feet), headache, pain behind the eyes and conjunctivitis. As symptoms are often mild, infection may go unrecognized or be misdiagnosed as dengue.

A high rate of asymptomatic infection with Zika virus is expected, similar to other flaviviruses, such as dengue virus and West Nile virus. Most people fully recover without severe complications, and hospitalization rates are low. To date, there have been no reported deaths associated with Zika virus.

It strikes me as odd that this virus has been known for decades in different parts of the world, and generally considered to be mild with limited side effects – until just recently. It got me wondering if their may be other factors involved, which I'll get to in a bit.

What is the treatment for Zika virus?

There is currently no vaccine for Zika virus, and it is treated symptomatically. Per the CDC:

  • Get plenty of rest
  • Drink fluids to prevent dehydration
  • Take medicine such as acetaminophen to relieve fever and pain
  • Do not take aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs), like ibuprofen and naproxen. Aspirin and NSAIDs should be avoided until dengue can be ruled out to reduce the risk of hemorrhage (bleeding). If you are taking medicine for another medical condition, talk to your healthcare provider before taking additional medication.

Can pets catch Zika virus?

At this time it is not known if pets can catch or transmit Zika virus.

Has Zika virus been found in the United States?

Those infected with the Zia virus in the United States appear to have contracted it while traveling abroad. You can view the CDC Zika travel advisories here.

Zika Virus and Birth Defects

In Brazil, authorities have linked Zika virus infection of expectant mothers with microcephaly in babies. Microcephaly is abnormal smallness of the head, a congenital condition associated with incomplete brain development.

Some sources are reporting over 400 cases of microcephaly in 2015 – which would be a massive increase from the 150 reported cases in 2014. However, it should be noted that, in the article “Brazil Revises Birth Defect Count in Zika Investigation“, “only 270 of 4,180 suspected cases have been confirmed as microcephaly, with the brain damage associated with the defect ruled out in 462 cases.” Also, only six of the 270 confirmed microcephaly cases (2.2%) were found to have the Zika virus.

Further:

The Health Ministry said Brazilian states were not required to report microcephaly cases before November. That could mean the 2014 list didn't fully account for all cases, though the ministry dismissed the idea there might have been a large number of unreported cases.

The U.S. CDC says about the rate of microcephaly in the U.S. is about 2 to 12 per 10,000 live births — a figure far higher than Brazil's estimates for earlier years.

While anything that endangers people's health is a cause for concern, I'm wondering if resources would be better spent improving the living conditions of the people so there are less spaces for the mosquitoes to breed, and working to make sure the mothers are well nourished during pregnancy, since maternal malnutrition has also been linked with microcephaly. Brazil is in the midst of a long term economic downturn, which has to be hard on families that are already struggling.

Zika Virus and Genetically Engineered Mosquitoes

A number of websites have posited that there is a link between the release of genetically engineered mosquitoes and the Zika virus birth defects. There are no studies or clear evidence to suggest this is the case.  Theories range from  wondering if the genetically modified mosquitoes were in fact designed to be disease carriers or are in some way more predisposed to be disease carriers more than indigenous mosquitoes.

As I've been reading more about epigenetics, they're finding that gene manipulation often has unintended and unexpected consequences. At one time it was though that all you had to do was swap out one gene for another to get the desired effect. What they're finding out now is that genes effectively have “switches” that turn the traits on and off – so one gene can carry many, many traits.

When they were isolating the genome to map it, they were stripping off the proteins to do so. Now they are finding that getting rid of those proteins was effectively throwing away half of the genetic information. So – is it possible that there's a link? Maybe – but it could be a case of correlation rather than causation.

What I can tell you from researching is that area where Zika and birth defect problems are exploding is a mosquito heaven. In 2015, Brazil had 1.6 million cases of dengue fever. While the country is busy spending money on soccer stadiums and Olympic venues, many of the people live in squalor, with open tanks, ditches and garage piles filled with stagnant pools of water – perfect mosquito breeding ground. The World Cup may have even introduced the virus to Brazil.

There is also likely to be a lot of money changing hands as more genetically modified mosquitoes are released and more pesticides are sprayed.

Another argument points to the recent requirement of all expectant mothers in Brazil to receive the Tdap vaccine. The Tdap vaccine is classified as a class C drug, which means “Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.” Could this be linked? Again, inconclusive at this time.

Brazil is the Largest Global Consumer of Pesticides

Many of you have probably heard of the Amazonian rain forest being cut down at an alarming rate. The massively diverse ecosystem of the rain forest is then replaced with huge swathes of often genetically engineered monocrops – like soybeans and cotton – that require huge amounts of chemicals to maintain.

From 2000 to 2012, Brazilian pesticide use increased 162%. In 2012, the Brazilian agriculture sector purchased over 823,000 TONS of pesticides.

Paulo Peterson, director of the Brazilian Agro-Ecology Association warns:

When genetically modified seeds were launched those in favor of using these seeds and crops argued that their use would lead to lower usage of pesticides because these plants would be more resistant to disease and pests.

Petersen argues that what has been seen in reality is the opposite. “Not only are we using more [pesticides] but we are using more powerful, stronger pesticides. We have been forced to import pesticides which were not even allowed in Brazil to combat pests which attacked GM soybean and cotton plants,” he is quoted as saying.

The executive adds that 22 of the fifty main active ingredients used in pesticides in Brazil today have been banned in most other countries. “We are facing a situation of total lack of control [of pesticide use]. The state does not monitor as it should and the legislation for the use of pesticides is not being obeyed.”

Previous studies have linked pesticide exposure to microcephaly and other birth defects.

More Studies Link Microcephaly and Pesticide Use, Not Zika Virus

The New England Journal of Medicine study “Zika Virus Disease in Colombia — Preliminary Report” concludes:

“Preliminary surveillance data in Colombia suggest that maternal infection with the Zika virus during the third trimester of pregnancy is not linked to structural abnormalities in the fetus.”

The New England Complex Systems Institute notes in “Is Zika the cause of Microcephaly? Status Report June 22, 2016“:

“…there is no direct link between Zika and microcephaly except for random co-occurrence. We note that the base rate of microcephaly in the absence of Zika is 140 per year in Colombia, which is consistent with the approximately 50 microcephaly cases in the first 4 months of 2016, only 4 of which have been connected to Zika. When interpreting Zika as the cause, background cases must be subtracted.

An alternative cause of microcephaly in Brazil could be the pesticide pyriproxyfen, which is cross-reactive with retinoic acid, which causes microcephaly, and is being used in drinking water.”

Maybe it's time to look at the whole situation surrounding the problem, instead of just treating the symptoms?

  1. Thank you for pulling all of this into one place, Laurie. I appreciate it 🙂 I saddened for the families who have already been affected and am quite concerned about the potential (probability) for this to inflict even further damage than it has already (in such a short period of time)! Scary times on many levels.

    1. Thank you for taking time to comment, as I know you have you hands full with the farm. There’s a lot of fear-mongering going on with this outbreak from many different directions, and fear is usually a bad perspective to take when working to solve a problem.

  2. There is always much more to the story than what is reported in our media. I had also wondered why all of a sudden Zika had become big news. Thanks for your in-depth research on this. The link with pesticides makes perfect sense.

    1. I have friends who live in tropical areas, and while they’ve mentioned dengue fever as a real problem, Zika never came up. It really got me wondering why suddenly this “mild” illness went rogue. Most of what I’ve read focused solely on just repeating the same info, instead of looking at the larger setting. Thank you for taking time to comment.

  3. Thanks for reporting on this current subject. It is odd that the Zika virus seems to have come out of nowhere. It is important to know how to keep our immune systems in good condition, because there is always some “new” virus out there!

  4. I suggest anyone interested in the truth about this engineered problem to check out Alex Jones website and his indepth interview with VERY knowledgable guest discussing this issue.

    1. I’m hesitant to link to Alex Jones site here because he can be very extreme, but there are times when he certainly gets to meat of the argument. In this case, one might hypothesize that if you had a bunch of countries with a booming population where abortion was illegal, and there were certain interests with a lot of cash who wanted to limit the population of the “unwashed masses”, those interests might create conditions that made the population at large reconsider their abortion choices or even having children at all. I’ve already seen plenty of news stories praising the push for legalized abortion in the affected areas. It’s also very strange that a normally mild virus could abruptly have such aggressive affects.

  5. Thank you for this post. The subject IS very confusing and quite a conundrum, isn’t it? Of course the press just loves to scare us all to death, too. I’d be willing, myself, to entertain the idea that it may well be that the birth defects are the result of all the chemicals used, rather than this virus. And something I’m scared of is whatever serum they develop to inoculate us all, because it will be something done in a hurry, and that’s dangerous.

    1. I’d love to see real effort devoted to cleaning up the mosquito breeding areas (like the garbage stacked with stagnant water), chemicals reduced, better prenatal nutrition, and no class C inoculations during pregnancy. If they do all that and there’s no improvement, and the babies actually test positive for the virus, then it would be pretty clear the virus was more suspect.

  6. Thank you for a more thorough write up than what I’ve seen so far. You helped me come up with a plan for this mosquito season and set my mind at ease a bit.

  7. Mosquito egg trap
    Build a mosquito egg trap which consists of a black container placed in the shade that fills with water automatically giving a place for mosquitoes to lay eggs. The water would drain every 12 hours to ensure the eggs dies on the ground. Make millions of these devices. A genetically engineering solution will never get rid of all the mosquitoes and will cost more as well as have potential unwanted consequences.
    Regards

  8. I think if everyone would just start being on the look-out in your own neighborhood for stagnant water and get others involved in your neighborhood to get rid of all those stagnant water areas, it would be one step on making sure Zika doesn’t stick around where you live.

  9. I am old enough to remember being intentionally exposed to rubella. Best thing to do is expose girls when they are young as it appears that one infrcyionlrads to immunity
