The fight against the Zika virus stalled in Congress on Tuesday when Senate Democrats blocked a Republican bill they said was stuffed with unpalatable measures, including a provision that barred Planned Parenthood from the emergency funding. With the $1.1 billion funding bill now dead in the water, lawmakers could fail to reach (http://www.politico.com/story/2016/06/zika-politics-congress-224857) a compromise before they leave for a seven-week recess next month.
It has already been more than four months since President Barack Obama first submitted a request for $1.9 billion in emergency funds to combat the mosquito-borne virus, which has been linked to devastating birth defects.
Congress' failure to respond to the crisis drew criticism Tuesday from the American Public Health Association. "We know Zika could cause hundreds of US infants to be born with preventable birth defects—if we don’t intervene," the organization's executive director, Georges Benjamin, said in a press release. He added that the latest bill was "both late and inadequate." Obama criticized (http://www.nytimes.com/2016/05/24/us/politics/obama-chides-congress-over-zika-funding.html) Congress for its lack of progress last month, saying, "They should not be going off on recess before this is done."
The GOP bill passed the House last Thursday under unusual circumstances: The vote took place over the shouts (http://www.vox.com/2016/6/23/12014360/zika-sit-in-democrats-gop-house) of Democrats holding an all-night sit-in (http://www.motherjones.com/politics/2016/06/here-are-five-most-memorable-moments-house-sit-guns-so-far) in an attempt to force a vote on gun control. Democrats sharply criticized the Zika bill for preventing emergency funding from going to the women's health organization Planned Parenthood, a favorite target of conservatives, even though the Zika crisis affects pregnant women. They also objected to a provision weakening regulations on pesticides.
Senate Minority Leader Harry Reid (D-Nev.) on Monday described the bill (http://www.nytimes.com/2016/06/29/us/politics/congress-zika-funding.html) as "nothing more than a goodie bag for the fringes of the Republican Party." Republicans, meanwhile, blamed Democrats for the holdup. "It's really puzzling to hear Democrats claim to be advocates for women's health measures when they are the ones trying to block the Zika legislation,” said (http://www.wsj.com/articles/senate-democrats-block-zika-spending-bill-over-exclusion-of-planned-parenthood-1467133283) Senate Majority Leader Mitch McConnell (R-Ky.). Tuesday's vote was 52 to 48, short of the 60 votes needed to break a filibuster.
As the partisan squabble stretches on, the Zika crisis is only growing. The disease has spread quickly in Puerto Rico, where the director of the Centers for Disease Control and Prevention warned this month (https://www.washingtonpost.com/news/to-your-health/wp/2016/06/17/cdc-director-puerto-rico-could-see-hundreds-of-zika-infected-babies-with-microcephaly/) it could result in "dozens to hundreds of infants born with microcephaly in the coming year." Nearly 2,000 cases (http://www.cdc.gov/zika/geo/united-states.html) have been reported in US territories, the vast majority of them contracted locally, according to the CDC. A total of 820 cases have been reported in US states. One of those was contracted in a lab; all the rest resulted from travel.

New doubts on Zika as cause of microcephaly
Date: June 24, 2016

Summary:
Brazil's microcephaly epidemic continues to pose a mystery -- if Zika is the culprit, why are there no similar epidemics in other countries also hit hard by the virus? In Brazil, the microcephaly rate soared with more than 1,500 confirmed cases. But in Colombia, a recent study of nearly 12,000 pregnant women infected with Zika found zero microcephaly cases. If Zika is to blame for microcephaly, where are the missing cases?

FULL STORY
Brazil's microcephaly epidemic continues to pose a mystery -- if Zika is the culprit, why are there no similar epidemics in other countries also hit hard by the virus? In Brazil, the microcephaly rate soared with more than 1,500 confirmed cases. But in Colombia, a recent study of nearly 12,000 pregnant women infected with Zika found zero microcephaly cases. If Zika is to blame for microcephaly, where are the missing cases? Perhaps there is another reason for the epidemic in Brazil. According to a new report by the New England Complex Systems Institute (NECSI), the number of missing cases in Colombia and elsewhere raises serious questions about the assumed connection between Zika and microcephaly.

Recently, the New England Journal of Medicine published the preliminary results of a large study of pregnant Colombian women infected with Zika. Of the nearly 12,000 pregnant women with clinical symptoms of Zika infections until March 28, no cases of microcephaly were reported as of May 2. At the same time, four cases of Zika and microcephaly were reported for women who were symptomless for Zika infections and therefore not included in the study itself.

Is it possible that more time is needed for births to give rise to the high numbers seen in Brazil? The numbers don't add up according to the NECSI report. The Zika and microcephaly cases that are not part of the study show that there are many more pregnancies affected by Zika without symptoms. Because there are four cases of microcephaly with Zika, and none in the study, there should be about four times as many cases of Zika that are unreported. This means there are at least 60,000 Zika-infected pregnancies in Colombia.

The NECSI report analyzes the data and shows that the four cases of Zika and microcephaly that have been observed till April 28 are just what would be expected due to the background rate -- of the 60,000 pregnancies about 20,000 births would already be expected. The expected microcephaly rate for countries with no reported infections of 2-in-10,000 births gives exactly four cases. The study also notes that until April 28 there has been a total of about 50 microcephaly cases in Colombia, of which only four have been connected with Zika. The four cases are expected for the coincidence of Zika and microcephaly in the same pregnancies even if Zika is not the cause.

In light of this evidence, NECSI says the cause of microcephaly in Brazil should be reconsidered. One possibility that has been raised is the pesticide pyriproxyfen, which is applied to drinking water in some parts of Brazil to kill the larvae of the mosquitos that transmit Zika. Pyriproxyfen is an analogue for insect juvenile hormone which is cross reactive with retinoic acid, which is known to cause microcephaly. A physicians group in Brazil and Argentina, the Swedish Toxicology Sciences Research Center, and NECSI have called for further studies of the potential link between pyriproxyfen and microcephaly.

I had read early on that insecticide might be implicated but the story disappeared. I have been suspect of the whole Zika thing ever since, there is a whiff of PR in the air. Might serve to cover the ass of some Big Chem outfit, it also kicks that uppity BRIC in the head with it's Olympics threatening to be a shambles.
