Zika-Linked Brain Damage In Infants May Be 'Tip Of The Iceberg'

$this->bbcode_second_pass_quote('', 'D')r. João Ricardo de Almeida says the infants born to mothers who were infected in the first trimester seem to suffer the most brain damage. And that kind of damage also appears to be different than what you would see with microcephaly caused by other types of infections.

"Regarding Zika there seems to be some particular abnormalities that we do not see in [microcephaly cases caused by] toxoplasmosis or cytomegalovirus or rubella."

A normal brain has ridges like coral. The brains of these babies look "like a smooth rock," he says.

He says the degree of brain damage he is seeing will probably mean that rehabilitation will be very difficult.

"They are not going to be functional," he says of the babies he has examined. "They'll need care for the rest of their lives."

Dr. Albert Ko from Yale University has been collaborating with the study in Bahia. He says that while the cases of microcephaly are getting all the attention, the Zika virus could be having a wider range of effects on the development of a fetus.

"We are seeing cases in the hospital of children who have normal size heads but are having neurological lesions and eye lesions," he says. "And we are extremely concerned ... this might suggest that [the microcephaly cases] are just the tip of the iceberg."

In other words, even children who appear normal may suffer from a range of developmental delays. So the deeper the investigation goes into this outbreak, the more worrying it becomes.

$this->bbcode_second_pass_quote('vox_mundi', '')$this->bbcode_second_pass_quote('Ulenspiegel', 'A')s I understood the high "infection rate" in Brasil is a result changed methodology. They now count everything that may be an actual infection. In most cases it is false alarm. The actual infection rate is probably more than one order of magnitude lower and not that much higher than in the last years IIRC.


Most cases implies a majority.

More than an order of magnitude lower implies greater than ten-fold reduction.

The question remains - how come

Microcephaly cases in all of 2014 = 140
Microcephaly cases in last 3 months = 4180

Did Brazil, global health agencies fumble Zika response?

The sketchy numbers behind Brazil’s Zika crisis


Is the medical body responsible for monitoring birth defects in Latin America trying to cover their ass?


Again, the methodology of counting changed. The 4180 cases are alerts, not more, the 140 cases are confirmed. And most of the 4180 cases were not the real thing.

I do not dispute that we will see a rising number of affected people, however, the number of confirmed cases is quite low, less than 10% of the 4180. Therefore, my statements were correct.

Brazil authorizes forced entry to private property to fight Zika

$this->bbcode_second_pass_quote('', 'R')IO DE JANEIRO (Reuters) - Brazilian President Dilma Rousseff authorized health officials to enter private properties by force if necessary in an effort to control the spread of the mosquito-borne virus Zika, which the government has dubbed an "imminent danger to public health."

Australian scientists may soon be at the forefront of the fight against the Zika virus in South America, using a biological control designed to combat dengue fever.
$this->bbcode_second_pass_quote('', '
')Professor Scott O'Neill, program director of Eliminate Dengue, a Melbourne-based, Australian-led international collaboration dedicated to wiping out dengue fever around the globe, said the organisation was in discussions with "governments in South America" about potentially adapting its work to combat the latest pandemic.

$this->bbcode_second_pass_quote('', '
')The biological control involves releasing populations of mosquitoes that have been infected with a commonly occurring species of bacteria, called Wolbachia.

The bacteria effectively inoculate the mosquitoes against the dengue virus. The treated populations then out-compete their dengue-carrying rivals, greatly reducing their numbers. Small-scale trials of the strategy started in 2011, and have so far been carried out in Queensland, Vietnam, Indonesia and Brazil.

The largest trial so far kicked off in 2014, with the release of Wolbachia-infected mosquitoes throughout Townsville.

$this->bbcode_second_pass_quote('', '
')The viruses that cause dengue and Zika are very closely related. Both are members of the Flavivirus family, which also includes the yellow fever and West Nile viruses. Both are transmitted by the same species of mosquito, known as Aedes aegypti.


$this->bbcode_second_pass_quote('', '
')
"It shows that Wolbachia blocks Zika in an almost identical way, so where we've put it out to block dengue the mosquito populations are also resistant to Zika."

Zika has been sexually transmitted in Texas, CDC confirms

http://www.cnn.com/2016/02/02/health/zi ... index.html

I think I read that the damage occurs in the 1st trimester mainly- so, in theory, a male could impregnate and transmit at the same time with the worst consequences.

This will speed transmission

'Nothing justifies an abortion': Brazilian Catholic archdiocese says women should not use any method of birth control to combat spread of Zika virus

$this->bbcode_second_pass_quote('', 'T')he only exception to this rule is 'natural family planning', which sees women only have sex at times in their menstrual cycle when they are less likely to succeed. It only has a 25 per cent success rate.

Catholics are awaiting guidance from the Church on what they should do, with some countries advising women to simply not have sex until the threat of Zika has died down. El Salvador has told people not to have sex until 2018

However, the Vatican declined to comment when contacted by the BBC.

Reverend Father Frank Pavone, national director of U.S.-based anti-abortion group Priests for Life, said Catholics should not use birth control regardless of the Zika virus.

'That prohibition doesn't change based on circumstances,' he told CNN.

'So couples have a responsibility to live according to the church's teachings in whatever circumstances they find themselves.'

Zika Outbreak Is a 'Temperature Driven Eruption,' Says Scientist

$this->bbcode_second_pass_quote('', 'W')hile it’s too early to say exactly why the Zika outbreak has been so vicious, our recent record-breaking global heat wave offers one possible explanation.

Warmer temperatures help Zika by increasing the habitat for its mosquito vector, while speeding up the biological processes that help the virus replicate. “With higher temperatures you have more mosquitoes feeding more frequently and having a greater chance of acquiring infection,” Bill Reisen, an entomologist at UC Davis, told the Associated Press. “And then the virus replicates faster because it’s hotter, therefore the mosquitoes can transmit earlier in their life.”

Hotter temperatures also make mosquitoes hungrier, entomologist say, causing them to partake in more blood feasts and upping the odds of their viruses passing to humans.


Florida Declares a State of Emergency in Five Counties

$this->bbcode_second_pass_quote('', 'F')lorida Gov. Rick Scott (R) expanded the state of emergency to a fifth county today where the Zika virus has been diagnosed. Although none of the residents were infected in the U.S., Scott said he wanted to be prepared for the upcoming mosquito season.

The five counties are Broward, Miami-Dade, Hillsborough, Lee and Santa Rosa.


Top airlines offer to re-assign crew from Zika-hit routes

$this->bbcode_second_pass_quote('', 'M')ajor U.S. airlines United (UAL.N), Delta (DAL.N) and American (AAL.O) and Europe's Lufthansa (LHAG.DE) and Air France (AIRF.PA) are offering to re-assign certain flight crew concerned about contracting the Zika virus from routes to affected countries.

The previously unreported policies by the U.S. airlines show how the mosquito-borne virus, linked to thousands of birth defects in Brazil, looms as an issue not just for airline passengers but for flight attendants and pilots as well.

In an internal memo on Jan. 28, seen by Reuters, United said expectant flight attendants as well as those seeking to become pregnant could switch routes to avoid Zika-affected regions without repercussions. The airline has similar options available for pilots.

Delta Air Lines Inc has also let flight attendants and pilots switch assignments since Jan. 17, and American Airlines Group Inc has encouraged crew to tell their managers of concerns in order to opt out of flights to Zika-hit areas, spokesmen for the companies said.

Major long-haul carriers Lufthansa and Air France also said they already offered crew members with any reservations about flying to a particular destination the chance to change a shift.


Zika virus's other looming threat

$this->bbcode_second_pass_quote('', 'W')hen the World Health Organization declared a global health emergency on Monday, it didn't cite the Zika virus itself as the reason. The emergency, it said, is the alarming rise in cases of microcephaly and Guillan Barre Syndrome (GBS).

While the WHO isn't ready to pass judgment on precisely what's to blame, (it specifies only "possible association with Zika virus") by citing Guillan Barre Syndrome, a debilitating neurological disorder, it has elevated our awareness of the threat posed by it.

GBS, an autoimmune disease, puts everyone, potentially, at risk - males and females, pregnant or not, and there's nothing we can do to make sure any particular case of Zika infection doesn't turn into GBS.

GBS hits all the criteria for a modern medical odyssey: It is mysterious in origin, requires some detective work, it carries the risk of death, it requires prolonged intensive care, it strains families, it can ruin finances, and in some cases it leads to lasting loss of function -- paralysis.


CDC Sees Major Challenges Ahead In The Fight Against Zika

New Link Between Zika and Microcephaly Is Found in Brazil

$this->bbcode_second_pass_quote('', 'R')esearchers in the state of Pernambuco, home to a third of Brazil’s suspected cases of infant microcephaly, said on Wednesday that they have identified some of the clearest evidence yet of a direct link between the debilitating birth defect and the Zika virus.

Researchers here tested the spinal fluid of 12 babies with microcephaly, all of whom were born to mothers who reported having symptoms of Zika early in their pregnancies. In all 12 cases, the researchers found evidence of Zika — results they described as stunning.

It occurs to me that microencephly only happens if women catch Zika during pregnancy and probably during the first trimester. It has also been shown that women who catch and recover from Zika before pregnancy have no adverse effects on development of the fertilized egg into a full term baby. Easy solution, take every non pregnant woman of child bearing age and inject her with Zika virus so she bets ill and has all her symptoms and recovers before she becomes pregnant. Figure out how long the immunity lasts and repeat as necessary.

That scenario would probably guarantee an additional 5-10,000 cases of Guillan Barre Syndrome in year 1, and would not protect the general population from GBS.

It would also create a huge carrier population that could distribute the disease globally, whether those other countries were ready for it or not.

There's a chance Venezuela's Zika outbreak is worse than Brazil's

$this->bbcode_second_pass_quote('', ' ')Julio Castro, a professor of tropical epidemiology at the Central University of Venezuela, says he believed between 250,000 and 400,000 people had been infected with Zika in Venezuela. He calculated those numbers by feeding the government’s limited official data and other reports of unexplained fever cases into epidemiological and mathematical models, he said.

Other Venezuelan experts, including some from the independent Network to Defend National Epidemiology, have come up with similar projections.

If those numbers are correct, that would mean Venezuela, with its 33 million people, could have a higher per-capita rate of Zika infection than Brazil, which has 205 million people, and where officials estimate there have been between 500,000 and 1.5 million infections.

Castro added that there are other reasons to believe that Zika is several times more prevalent in Venezuela than Brazil. They include the fact that Aedes aegypti, the mosquito that carries the disease, is present in 16to 20 percent of Venezuelan homes but just 4-5 percent of Brazilian homes, he said.

$this->bbcode_second_pass_quote('', 'H')uniades Urbina-Medina, president of the Venezuelan Pediatric Society, agreed, warning that he feared Venezuela could be on the brink of a more concentrated wave of microcephalic births than Brazil has witnessed.

“We can expect the first births from mothers potentially exposed to Zika in March and April and right now, we simply have no idea what is coming,” he said. “That lack of information and transparency [about the number of Zika infections] would be unthinkable in a serious country. Of course, I am extremely concerned.”

Urbina-Medina also cited the government’s dropping of its weekly public health report, which included current numbers of cases of infectious diseases. “Remarks from officials every now and then, on an ad hoc basis, are not enough for us to be able to address this problem,” the doctor said.

$this->bbcode_second_pass_quote('', ' ')Urbina-Medina says that, with the exception of a single government hospital in Caracas, Venezuela even lacks the supplies to test for Zika and give definitive diagnoses.

Just as worryingly, the doctor says a shortage of new machines and parts to repair old ones means many hospitals in Venezuela are unable to carry out ultrasound scans to determine the health of babies in the womb.

“Venezuela is not in a position to address public health crises,” Urbina-Medina said. “Right now, there is a national deficit of 70,000 intensive care beds. The future is very dark for our patients, and even for our doctors as they are especially exposed to Zika.”
