One of the big health issues to emerge in 2016 is
the Brazilian epidemic of babies tragically born with 'microcephaly'
(undeveloped brain) and other deformities.
Between October 2015 and January 2016, some 4,000 cases of malformation
were reported, with 49 deaths. Health
officials were quick to blame Zika virus which had been first identified in
Brazil in April/May 2015.
Zika reproduces in many mammalian hosts,
especially monkeys, and is transmitted between hosts by a number of mosquito
species although direct exchange of body fluids is also a likely route. However, only two years ago, scientists from
Brazil and Senegal noted that "humans are occasional hosts" for
Zika with "only 14 human cases reported before April 2007".
Historically, most Zika infections in
humans have no symptoms, and at worst, cause a minor illness with no
distinctive characteristics. However,
since its discovery in 1947 and unusually for this type of virus, Zika seems to
have undergone a number of genetic changes.
This, plus an outbreak of Zika fever on an island in Micronesia in 2007,
demonstrated that Zika had the potential to be an emerging disease. Indeed, the current outbreak of the virus in
humans has quickly spread across South and Central America, Mexico and the
Caribbean.
The coincidence of geographical
distribution plus timing of the Zika infection and the emergence of microcephaly
which led to suspicions of a link has since been backed up by laboratory tests:
the virus has been found in amniotic fluid, brains, or spinal fluid of
afflicted babies; nearly a third of foetuses carried by women who had Zika
virus in their blood or urine had abnormalities; laboratory tests of cultured
cells established that Zika interferes with early brain-cell development.
Besides brain malformation, Zika is now
being linked with foetal death, foetal growth restriction, placental
insufficiency, and central nervous system lesions. In adults, there's a suspicion Zika can cause
autoimmune reactions in the nervous system.
So far so good. But then the sceptics began to ask questions.
Blaming a virus for a health problem is a
cop-out: it's God's fault.
In countries other than Brazil, Zika
epidemics infecting 75% of the populations did not cause birth defects.
There's something very different about the Zika in Brazil now and the
Zika previously prevalent. Old Zika had
the potential, it seems, to attack brain cells (as shown in the cell culture
experiment), but New Zika can do it much better and does a lot more besides.
Because mosquitoes transmit other, serious,
diseases, such as Dengue fever and malaria, the Brazilian government has had
major programmes in place to reduce their numbers for some years. These have included decades of insecticidal
chemical treatments, the most recent being the World Health Organisation
recommended larvicide, 'pyriproxyfen', added to drinking water since
mid-2014. This was boosted during 2012
by weekly releases of 540,000 Oxytech male GM mosquitoes whose GM offspring are
programmed to die [1], after which the company claimed a 90% reduction in the
mosquito population. All these would be
expected have already reduced the Zika problem at the level of its vector.
Nevertheless, by 2015, the World Health
Organisation reported Zika in Brazil, and only a few months had passed before
the rise in microcephaly there was apparent. Mosquitoes can't fly more than 400
meters, and the virus is shed from the body within 3-14 days. Yet, the Brazilian Minister of Health
suspects anything from 330,000-3,000,000 cases might have occurred during that
year*. The new disease-causing Zika
seems to have exploded out of nowhere.
* Because
the immune-system reactions used in lab tests for Zika are so similar to those
of Dengue virus which is endemic in the same areas, identification of a Zika
infection after the event is very uncertain.
Indeed, the suddenness of the emergence of
the malformations seems to indicate a precisely-timed man-made cause, rather
than a natural biological spread of a new viral variant.
Although industry safety studies of
pyriproxyfen haven't picked up reproductive, developmental or neurotoxic
effects, Argentinean doctors have raised their concerns that the mass exposure
of the population to pyriproxyfen in drinking water (where it could have become
concentrated) is a much more likely culprit.
On the other hand, glyphosate-based
herbicides used extensively on GM soya crops in Brazil have also been linked to
birth defects and microcephaly.
Others have pointed out that the centre of
origin of microcephaly is also the location of the mass-release of GM
mosquitoes. These novel mosquitoes were
transformed using mobile DNA elements which can jump into (and out of) genomes.
Transgenic offspring are supposed to
self-destruct, and the GM males released will quickly die out: but the
technique is leaky and opportunities for Zika to be destabilised by mobile
elements in its vector may be present.
A Zika-based conspiracy to promote
population control through a 'voluntary' no-child policy throughout the South
American countries has also been proposed.
Or, perhaps more likely, a Zika/mosquito
cover story whipped out to conceal the government-backed damage inflicted
through the use of a whole raft of toxic chemicals supplied by some of the most
powerful corporations on the planet.
What is certain is that the pharmaceutical
industry will make a packet producing anti-Zika vaccines, and that the chemical
industry will make a packet producing insecticides to kill off the mosquitoes.
Oxitech, which has not so far found much enthusiasm for its GM weapons of
mass-insect-destruction, will find its products in hot demand (at a price)
because even the World Health Organisation has now ordered more GM mosquito
trials. And gene-drives [2] to wipe out all
mosquitoes are certainly on the menu.
OUR COMMENT
As reported by GM-free Scotland before, the
effect of reducing the mosquito population to control Dengue fever seems to
have made the problem worse [1], and seems curiously to be linked to the
'explosion' of Zika too.
From a biological point of view, the abrupt
decline in the virus's vector population, plus the unnatural changes in
physiology of the GM mosquitoes mating with the females which transmit the
virus, plus physiological changes in mosquito vectors after sublethal exposure
to pyriproxyfen, present an ideal scenario for a pathogen to 'save itself' by
becoming more virulent.
Clinicians already know that reactions to a
second infection by Dengue are worse than the first. Since Zika is very similar to Dengue, these
two pathogens together could be acting synergistically on their common host.
And, of course, exposure to a cocktail of
glyphosate, pyriproxyfen, Dengue and New Zika might realistically account for
the wide variety of malformations and problems observed.
It's been pointed out that measures such as
stimulating biodiversity to encourage mosquito predators, covering stagnant
water to prevent mosquitoes from breeding, and putting fish into the water to
eat mosquito larvae will all keep mozzie numbers down, keep viral transmission
minimal and promote natural immunity in the human population without resorting
to chemicals, vaccines, or GMOs.
