Approaches To Reduce Future Viral Infections

Part 3 of 3:

Approaches To Reduce Future Viral Infections 

Will the eradication of mosquitoes eliminate viral illnesses?

Has it been proven the eradication of mosquitoes will decrease the diseases Dengue, Yellow Fever or Zika Virus?

Has it even been proven that using GM mosquitoes will reduce viruses transmitted by Aedes mosquitoes?   

What is the viral transmission rate of GM mosquitoes to human hosts? 

Answers to such questions would allay much public concern and fear about GM mosquitoes and pave a path for our future direction.

Instead, we are given reassurances from agencies that often wear the same hats as those they regulate.

Part 2 of this series raised the issue that our targets are misguided. Instead, we should target viruses (that are not considered living) rather than living insects. Mosquitos  are vital to our ecosystem.

In addition, why had an outbreak occurred in areas where GMM were released? Why didn’t GMM mosquitoes prevent the Zika outbreak? 

These are questions weighing on the public that need to be answered for GMM, to gain widespread public approval. Why have they not been answered?

Yet the WHO and the FDA have deemed it safe to use in light of the Zika epidemic. A spread caused not by mosquitoes but by a virus.  Zika virus clearly mutated in Brazil, being now linked to microcephaly  with sporadic cases  transmitted sexually.  Another feature unique to this mosquito-borne infection is it changed target to human offsprings and expanded its mode of transmission. 

If recent patterns foretell the future then Zika will be one in a long line of such viruses.

Genetic mutation vs genetic modification?

Does Climate Change enhance genetic mutation?

Did the changes in the climate accelerate reproductive cycles of the mosquitoes as well as the virus?

And how do viruses adapt to genetically-modified mosquitoes? Male mosquitoes don’t bite, but what is the survival rate of GMM offsprings in different locations?

Instead of the eradication of mosquitoes, let us consider trying new approaches where short, medium and long term benefits are all possible.

I suggest a rapid mobilization of the training and certification of more labs to perform Zika testing. Rapid testing facilitates rapid diagnosis and thus prevents spread. 

 

Improved infrastructure that raises the standard for all.  Universal healthcare is necessary as well as updated, repaired and replaced sewage, sanitation and pipes. These are goals that should now start. It will not only provide short term benefit but also long term benefits, as marked reduction in infections are noted as well as some cancers and autoimmune diseases.

Our research focus should include the public concern. Research must not solely be based on the researchers’ interests, but those of the community involved should have equal weight.

Researchers are experts in their fields but the community is an expert in what it sees. Many researchers lack first- or even second-hand knowledge. Engaging the public in initiating research may change the direction and lead to meaningful and lasting solutions to problems.  We live in connected environments.

Our focus should go beyond vaccines and develop ways humans can become unsavory to man’s greatest enemy, the virus itself.

Could Mutated Zika Cause Microcephaly?

Part 1 of 3:

Could Mutated Zika Cause Microcephaly?

Could the transmission of GMM (genetically-modified) mosquitoes cause mutations in the Zika Virus, resulting in microcephaly?

Despite assurance from agencies (like the WHO and the FDA) that GMM is completely safe and without harmful effects, the evidence is not strong enough to substantiate safe distribution of GMMs.

That kind of assurance was said of the Monsanto herbicide Round-up. Which is now reportedly linked to cancer! It was also said of GMO foods that are now linked to numerous cases of autoimmune disease.

Yet GMO labels are still not mandatory on food products and there is legislation to ensure it stays that way.  Without labels we will be unaware of GMOs in our foods and not know why we are afflicted with certain common cancers.

The hidden or non-use of GMO labels will certainly delay any future links of GMOs with illnesses, prevent parties from taking responsibility and impede on the public’s’ right to safe dietary consumption. This kind of carelessness or disregard leaves the public ignorant and open to hazards.

Has Zika been genetically modified?

Zika, which was first discovered in Uganda in 1947, has suddenly and without reason went from an asymptomatic infection to a global public health emergency. How did that happen?

In Brazil a Zika outbreak was associated with an outbreak of microcephaly. Strong evidence suggests the Zika Virus caused microcephaly and other birth defects in human offsprings. Based on news reports, it appears the link between Zika and microcephaly is isolated to Brazil. In the past, French Polynesia had a similar link.

While the Zika outbreak continues to wreak havoc in Latin America and the Caribbean, microcephaly appears only in Brazil. The areas where GMM were released are the ones where this link is strongest. This is a fact that is currently buried in the hysteria caused by Zika being linked to microcephaly. Panic that seems bent on leaving certain stones unturned and untouched.

Instead, mosquitoes are now viewed as dangerous to the survival of humans and slated for eradication, using the most expensive and high-tech approaches afforded the military and Big Pharma. But isn’t it the virus that caused the disease, not the mosquitoes?

Outbreaks in Brazil started in areas where GMM were released. Could there be now a new mutation, a new viral strain?

Will the war on mosquitoes prevent certain viral infections? Or will the viruses mutate and find new hosts?

Can we eradicate mosquitoes without adversely impacting on our ecosystem?

Basic questions yet again unanswered and unexplored, the smokescreen, red flags paving the path for further investigation.

Oxitec GM Mosquitos Linked To Zika Outbreak 

Back in September 2010, a scientific report voiced concerns about the 3-4 % that would survive. The scientists wanted to do further investigations before releasing GM mosquitoes.

The report warned that transgenes (transferred genes) can lead to changes that are unintended, unpredictable and unrelated to the nature of the gene inserted.

In July 2012, praised British company Oxitec introduced its genetically-modified mosquito farm. Reportedly, the goal was to decrease the incidence of dengue fever.

In July 2015, shortly after releasing the 18 million GM mosquitoes into the wild in Brazil, Oxitec announced their success in controlling the Aedes aegypti mosquitoes without much data on the impact to the ecosystem.  Please note this is the same area of the recent outbreak of Zika infection.

Oxitec GM insects (designated OX513A),  were genetically altered male Aedes aegypti that mated with non-modified female Aedes mosquitoes in the wild.

 

Oxitec GM Mosquitos At The Epicenter Zika Outbreak.

Brazil started deploying GM mosquitoes to reduce the natural Aedes mosquito population that transmit dengue fever.

The production of offsprings triggered transcription in the modified part to kill the larvae before breeding age, provided no tetracycline (antibiotics) exposure during development.

Brazil is third in the World for using tetracycline with farmed animals. This is not well absorbed and over 75% is excreted into the soil. GM mosquitos looking for food can ingest this tetracycline as part of their blood meal. Even small amounts will suppress the modified development, allowing the altered mosquitoes to survive.

Tetracycline represses the GM-designed development. Small amounts of tetracycline can result in a survival rate as high as 15%.

It turned out that cat food was used to feed the larvae in at least one lab. This cat food contained factory-farmed chicken which also contains tetracycline. This was discovered when a disparity was noted in survival rate testing results, with one lab testing at 15% survival rate (the one with cat food fed larvae) and another testing in at just 3%.

Scientist Dr Ricarda Steinbrecher voiced concern regarding the release of GM mosquitoes without field cage studies.  She raised many questions, that required answers, to reduce the risk to mankind and other animals.

Earlier this year, scientists at the Max Planck Institute for Evolutionary Biology in Germany examined information regarding the release of modified insects into the environment in Malaysia and Grand Cayman, which were carried out by Oxitec. The scientists’ findings suggest that there are “deficits in the scientific quality of regulatory documents and a general absence of accurate experimental descriptions available before releases start”. (3)

The Zika outbreak in Brazil followed Oxitec’s release of GM mosquitos.  The release location is the epicenter of the outbreak where a surge in babies with microcephaly was noted.

Recall GM mosquitoes act to produce abnormal offsprings in the natural Aedes mosquitoes, so they die before breeding.  Interesting  the Zika virus in pregnant women causes abnormal human offspring with reduced life expectancy.

Questions For Oxitec  Before Release Of More GM Mosquitos

Here are questions that should be considered and answered before Oxitec is allowed to release more GM mosquitoes into the wild.  Most of the following questions were asked by Dr Steinbrecher in a letter to the National Biosafety Board (NBB.  World Health Organization scheduled an emergency meeting about Zika on Monday, February 1, 2016.

Let’s make sure Oxitec does not release more GM mosquitos before responding to the following questions and other questions that link GM mosquitos to the recent Zika  virus outbreak in Brazil.

When released into the wild:

  • Will the bite of the female LMO mosquito change?
  • How is the life cycle of the male mosquitos changed after genetic modification?
  • Will the reaction of humans or animals to the mosquito bite change?
  • Are there different immune reactions due to compositional changes in the saliva of the mosquito?
  • Will the pathogen vector interaction change in female mosquitoes?
  • Did the level of dengue virus present in the saliva change?
  • Did the affinity to dengue virus change?
  • Are there new interactions with other viruses?
  • Do different environments result in different altered phenotypic and behavioral characteristics?
  • Do different condition, biotic and abiotic stresses result in different survival rates?
  • What is the emergency response should GM mosquitos  harm humans or other animals?

Zika Virus May Have Crossed Over to Common Mosquitos 

The Zika Virus may have already crossed over to the common mosquito. Scientists in Brazil are about a month away of confirming whether the Zeka Virus is also carried and transmitted by the more common Culex Mosquito.

Culex mosquitoes are 20 times the population of Aedes aegypti, and more widespread in most of America, parts of Africa and Asia.

Little is known of the Zika Virus that is linked to over 3,000 babies born with microcephaly. Zika was first isolated in African monkeys in 1947. It is a flavivirus (a genus of viruses), in the same family as dengue and chikungunya.

The Zika Virus is linked to the startling outbreak in Brazil, with 3-4 million people infected in fewer than 12 months. Plus a 20 to 30 fold surge in the birth of children with microcephaly.

In many of these cases, the RNA (acid) from the virus was isolated both in mother and child. Currently, there are no cures, antivirals or vaccines available. The CDC (Centers for Disease Control) recommend serial ultrasounds of high risk pregnant women.

The risk of microcephaly in women infected during pregnancy is up to 1%. The pregnancy is usually normal and newborns may appear like uninfected babies. However, in the first year, the baby will develop the features of microcephaly. Also part of the clinical picture are hearing and visual impairments, mental retardation and diminished life expectancy.

To-date 22 countries are currently affected and that number is increasing. The virus crossing over to the Common Mosquito will see an explosion in those infected, once the warmer weather gets here.

What is Microcephaly?



Simply stated, microcephaly is a small head. The head circumference is abnormally low (in the bottom 3% for age and sex). A small head means a small brain! Children with microcephaly have cognitive dysfunction and are at risk of seizures. In addition to the very unpleasant symptoms mentioned already.

According to the CDC, normally 2 to 12 out of 10,000 live births develop microcephaly. It is an extremely rare disease.

The possibility of this virus crossing over to other, more widespread mosquitoes, presents a global public health emergency.

With regards to North America, the colder weather in Canada makes the virus less likely to spread that far north. However climate change may change all that.

Why now?

In 2014 Brazil, Tdap (Tetenus-Diphtheria-Pertussis) was recommended for all pregnant women in Brazil. Further details are scant.

Of note for the conspiracy theorists, Tdap was used in pregnant women throughout the world for a number of years withOUT a surge in children born with microcephaly.

Brazil started deploying GMO mosquitos to reduce the natural mosquitoe population. Scientists in Brazil have focused on the Zika virus as being linked to microcephaly.  If so, then the cross over to the common mosquito puts the rest of the World at risk.

Until we know more, exercise caution.
