Have 30 seconds? Here’s what you need to know about the Zika virus.

Friday, June 30


A programming note

This will be the final weekly edition of Zika in 30 Seconds. Thank you for reading as, over the last 17 months, we’ve tracked the developing science, the progress toward a vaccine, and the many questions still unanswered about Zika virus.

Still, our coverage of Zika will continue. Going forward we’ll use this space to alert you to important news about Zika as it arises — so stay tuned.

And for more regular updates about Zika, follow STAT’s senior writer for global health Helen Branswell on Twitter.


On people’s lips

“The fight against Zika virus is not a 100-m race, but rather a marathon in which science and public health need to work hand in hand for the benefit of our peoples.” — Carissa F. Etienne, director of Pan American Health Organization

What lies ahead

The dramatic global rise of Zika in 2016 was followed by an equally dramatic decline by the end of that year — the reasons for which epidemiologists are still sorting out. But, global health expert Dr. Peter Hotez writes, “While countries such as Brazil no longer seem to be sustaining new transmission, there are new foci popping up in additional Latin American countries, including Ecuador and Peru on the Pacific Coast of South America, as well as in Argentina and Bolivia.”

In the U.S., he says, Florida seems less at risk this year than it was last year, when the state saw more than 200 cases of local Zika transmission.

But, Hotez writes, spread of the virus in Mexico may mean that local cases in Texas crop up later this year.

The bottom line, he says? We’re in a “new normal” for Zika and other similar viruses, both in the U.S. and globally.

What’s new this week

  • A group of Florida lawmakers is urging the U.S. Army to hold a hearing on its plan to give Sanofi an exclusive license to develop a Zika virus vaccine, a move that has raised concerns the product may be priced too high for many Americans, even though it was developed with taxpayer funds. (STAT)

Learning the hard way

  • When Zika struck last year, officials in Miami-Dade County immediately began fogging with permethrin, the active ingredient in home bug-killers such as Raid. Permethrin was sprayed at least seven times, but by the end of August, the county realized the poison had little effect and stopped using it. Officials didn’t get around to testing which pesticides kill Aedes aegypti until October — midway through Zika season. (Miami New Times)

Inside STAT: Fading from view

The public’s sense of alarm over the Zika outbreak has subsided — posing a challenge to health officials who want to keep it on the radar of the people who need to pay attention. Puerto Rico declared its outbreak over this week; Brazil said its emergency was over in May. In the United States, summer approaches with little discussion of the virus outside public health circles. But the risk to pregnant women traveling abroad is still real, and not going to change anytime soon. Read more.

India’s Zika silence

In the wake of India’s disclosure last month to the WHO that it had detected three cases of Zika, a number of questions have been raised about why the cases weren’t announced months ago. The Washington Post reports that health ministers said they knew about the country’s first case of Zika back in November of 2016, but they didn’t alert the public because they didn’t want “people to start panicking.” Meanwhile, The Wire points out, the country’s disease surveillance index still says zero cases of Zika have been found in the country, and the WHO has moved India up from the safest category 4 to category 2 in its ranking of Zika risk.

How microcephaly happens

A new paper sheds further light on why the Zika virus takes its most dramatic toll on the developing brain: Because a protein found in those cells helps the virus reproduce. The protein, called Musashi-1, is found in high levels in precursors to neurons — but if Zika virus is present it acts like a sponge, depriving the neurons of the protein. In fact, one family with a congenital mutation in the Musashi-1 gene has two children with microcephaly, the researchers point out, adding further evidence that this protein is key to normal brain development. That discovery may hopefully help scientists devise a way to stop the damage from occurring.

Response, in retrospect

The GAO this week released a report on the US government’s response to the Zika epidemic, concluding that the CDC and many states were underprepared to battle the outbreak. The report finds that the federal government could do better specifically on distributing and regulating diagnostic tests and on communicating geographic risk of the virus. The steps that the report concludes that the HHS should take are:

  • Establish a transparent process to provide CDC diagnostic tests, upon request, to manufacturers that are in the final stages of diagnostic test authorization.
  • Include information on CDC-developed tests distributed to or shared with public health laboratories on CDC’s website, including laboratory developed tests.
  • Provide details such as collection records, dates, and data limitations on posted and disseminated mosquito distribution maps to better inform mosquito control experts and the general public.
  • Consolidate information from individual diagnostic test labels and make this information available in a form that enables users to more readily compare information across tests.
  • Require manufacturers to list the identity of comparator assays on their diagnostic test labels.

A startling case study

A recently published case study describes an American adolescent who contracted Zika on a trip to the Caribbean. Symptoms of sore throat, headache, rash, and joint pain resolved soon after the individual returned to the US, but a range of worrying psychiatric symptoms — including “excessive energy, decreased sleep, rapid and tangential speech, grandiose thinking, impulsivity, and decreased inhibition” — stuck around for weeks afterward and even necessitated a period of hospitalization. Fifteen weeks after symptom onset, doctors reported, the patient’s symptoms were better but not gone. All told, they write, the case “raise[s] the possibility that Zika virus infection may trigger neuropsychiatric and cognitive symptoms.”

Fighting cancer with Zika?

Studying Zika’s tragic effects on fetuses has revealed two key qualities of the virus: It can cross the blood-brain barrier, and it specifically targets the developing brain. Now scientists are wondering whether those qualities might make the virus a cancer-killer. A newly funded research project in the UK will examine, in cells and in mice, whether Zika virus can selectively attack and kill brain cancer cells.

A key challenge of delivering drugs to the brain is the blood-brain barrier, which prohibits many molecules from passing into the brain — but Zika appears to be able to pass. What’s more, glioblastoma cells — a highly lethal form of brain cancer — resemble fetal brain cells in a number of ways. Combining those two lines of reasoning, scientists are now embarking on a project to see how Zika interacts with the cancer.

Testing advice changes for pregnant women

The CDC is now suggesting that women thinking of getting pregnant, and who may be exposed to the Zika virus, should consider having their blood tested for Zika antibodies before they get pregnant. That’s because IgM, a type of antibody triggered by Zika infection, can stick around in the blood for months, and doctors can’t always tell if the infection happened before pregnancy — which poses no risk to the fetus — or during pregnancy, when it’s a high risk. To distinguish those two scenarios, women at risk of exposure should ideally be tested before pregnancy and again each trimester.

Rift between Puerto Rico and CDC

Of all the states and territories, US health officials last year were especially worried about Zika’s potential impacts in Puerto Rico — which was part of their motivation to create the Zika Active Pregnancy Surveillance System to track pregnant women and identify infants and fetuses with Zika-related birth defects. The CDC awarded Puerto Rico’s Department of Health $9.5 million for the project. But since then the agencies have had a protracted feud, a document obtained by STAT shows, with the CDC claiming that health officials disregarded the established case definition for identifying affected infants — creating the illusion of far fewer affected infants than there may in fact be.

Since the beginning of the Zika epidemic in 2015, doctors have realized that Zika congenital syndrome can manifest itself in profound ways — brain tissue missing — or subtler deficits, such as hearing loss and vision problems. STAT recently revisited two affected babies — Duda, age 18 months, and Sophia, 1 year — whose divergent stories show the varied effects of the virus, and its profound impacts upon families.

The case of the missing cases

As Zika surged across the continent last year, US health authorities warned that Puerto Rico was facing a perfect storm. And more than 3,300 pregnant women there are known to have contracted the virus. But the number of babies born in Puerto Rico with microcephaly and other birth defects caused by Zika is unexpectedly low — just 16 cases — which is leading experts to question whether the island territory is downplaying its Zika spread, possibly to protect its tourism industry.

Brazil’s Zika mystery

After so many Brazilian babies were born with microcephaly in 2015, the country braced itself for a similar tsunami in 2016. But it didn’t materialize — and researchers have been trying to figure out why. A new paper offers a theory: The authors suggest the region’s first wave of Zika may have been its only wave of Zika to date. Illnesses in 2016, by that reckoning, were caused by a different virus producing lookalike symptoms to Zika — likely the chikungunya virus — but not causing microcephaly. In some ways, that’s good news; it might suggest Zika outbreaks are swift. But it doesn’t mean the virus is done. More likely, said senior author Christopher Dye, is that Zika will return after births create pools of people who have no immunity to the virus, hitting perhaps when people aren’t expecting it.

Budget concerns

President Trump’s budget released last week contained a provision that would eliminate one-eighth of the CDC’s budget. But in addition to that, there’s a more specific provision that would threaten Zika funding directly, points out Ed Yong at the Atlantic: A halving of the budget for the Epidemiology and Laboratory Capacity (ELC) program. That program helps state public health laboratories train their staff and buy equipment; these labs are in many cases the ones running blood tests for Zika. When, for instance, Congress failed for months to fund a Zika response last year, Minnesota’s public health laboratory used ELC funds to begin its public testing. With half as much funding, researchers say, being prepared for the next public health threat will be much harder.

Intimate portraits of Zika families

A deeply reported feature in the New York Times takes a look at some of Brazil’s Zika babies, now a year old but many of them with developmental levels of just a few months. “The children are still small enough to be held, fed and carried,” Pam Belluck writes. “But ultimately, many may be unable to walk, attend regular schools, or live on their own as adults.” That paints a dire future for families who are already barely keeping afloat. Read the full story here, and read a reporter’s notebook from the scene here.

Prevention is the best medicine

Miami this week detailed its preparation for spring and the arrival of mosquito season — which, it says, never really flagged. That includes spreading pesticide and larvicide, doing on-the-ground inspections, and keeping up with their “mosquito surveillance network” of more than 130 bug traps across the county. So far this year no US residents have contracted Zika from a local mosquito.

D.C. lab latest

More details have emerged about how a public health laboratory in Washington, D.C., bungled hundreds of Zika tests. The Washington Post reports:

There were two types of solution the District could have purchased to conduct a phase of the test. One bottle came marked with a “D,” for diluted, and the other with a “U”, for undiluted. D.C. lab workers had purchased the diluted version, Tran said, and then mistakenly watered it down as if it was the more concentrated one, weakening the ability to detect for Zika.

That mistake, missed for more than six months, is a worrisome failing — enough so that officials from the Centers for Medicare and Medicaid Services have now audited the lab, the Post reports, to determine how the mistakes were made and whether they’ve been fully rectified.

Screening scandals

Politics isn’t the only realm that’s seen some shocking headlines this week — Zika has as well.

In one case, a pregnant Las Vegas-area woman has tested positive for Zika, the county’s first non-travel related case. Health officials say she caught the virus via sex; her partner previously tested positive. But, according to local television station KLAS, he was never informed of his test results, in what’s being blamed on a “computer glitch.” It’s not yet clear whether the woman’s fetus has been infected with the virus.

And on the other side of the country, scientists at Washington, D.C.’s public health lab botched Zika tests for more than 400 people from July to December 2016. The “mathematical error” meant that people were getting negative test results when they could have actually been infected. So far officials have identified two pregnant women who were incorrectly told they did not have the virus when in fact they did, reports the Washington Post.

What Trump’s abortion policy will mean for Zika

The reinstation of the “Mexico City Policy” by President Trump this week could have ripple effects in the fight against Zika virus. That policy prevents foreign nonprofit groups that receive federal funds from administering abortions or providing abortion counseling or referrals. That could mean a hit to the budget of some nonprofits dealing with Zika, if they continue counseling patients about abortions. What’s more, research has shown that the policy in the past has hampered distribution of contraceptives in affected countries. Family planning and contraception are a key strategy in reducing pregnancies affected by Zika, according to the CDC.

  • which are the key genetic and molecular determinants of pathogenesis;
  • how long the virus persists in human blood and tissues and its transmissibility;
  • and how the innate and adaptive immune responses can counteract the virus and protect from reinfection.

  • After WHO declared the Zika virus no longer an “emergency,” tropical hotels saw an immediate and strong resurgence of bookings (New York Times)

Mixed messages

How often Zika virus infection causes birth defects is an open question — and two new reports this week not only failed to arrive at a consensus, they may have sown more confusion. One, in pregnant Brazilian women with Zika, found a 42 percent likelihood of birth defects; the other, in pregnant American women with Zika, found that birth defects affected just 6 percent. STAT consulted a number of experts and there appears to be no single answer that explains the huge gap — but differences in geography, disease status, and how birth defects are defined could be contributing to the disconnect. More studies, in the works now, should shed further light on the true risk. (STAT)

Vaccine vagaries

Three experimental Zika vaccines are being tested in people; another four or five should start human trials between now and next fall. But the question looming over the research is how much demand there will be for a Zika vaccine by the time any of them make it through three rounds of human testing and approval from the FDA. Drug makers are having to consider a range of possibilities — a Zika vaccine being added to a schedule of vaccines given in childhood, simply being marketed to travelers, or perhaps just being stockpiled to protect against a future epidemic — all of which portend different profits.

Legislative limbo

At the ballot box on Tuesday, residents of the Florida Keys expressed mixed feelings about field trials of a genetically modified mosquito made by Oxitec — the county voted yes, but the town of Key Haven, which had been the planned release site, said no thanks. Though the referendum was nonbinding, most members of the Florida Keys Mosquito Control District said they would honor it. Now, Wired reports, the board will try to work with the FDA to find a different release site. “We’ll be looking at where mosquitoes are, and come up with some other sites of where to release them based on where people voted yes,” said chairman Phil Goodman.

Mixed mosquito findings

Brazilian researchers at Fiocruz institute have found that the common Culex mosquito is not transmitting Zika in Rio de Janeiro. That’s good news, since those mosquitoes outnumber Aedes aegypti 20 times over. But it also leaves scientists scratching their heads, since their previous work indicated Culex mosquitoes in Recife could harbor the virus. One possibility, that might also help explain why Recife was so much harder hit: Culex mosquitoes in Recife may be genetically different from those in Rio, the institute said. (Washington Post)

Congress returns to work

Congress came back from summer recess yesterday and, as expected, a Senate vote last night failed to advance $1.1 billion in funding for a Zika response. A poll commissioned by the March of Dimes finds that 75 percent of Americans support increasing funding to fight Zika. But apathy about the severity of Zika continues to pervade Congress, even as nearly 3,000 cases of Zika have been diagnosed in the continental US.

Brazil’s Zika babies grow up

The immense cost of raising Brazil’s babies with congenital Zika syndrome is straining poor families and the government that supports them. The epidemic is overwhelming hospitals and clinics, which struggle to find enough doctors, therapists — and even basic supplies, such as infant feeding tubes — to meet the need.

STAT’s Melissa Bailey went to Recife, the epicenter of the crisis, to meet the family of one of the country’s first diagnosed infants with the syndrome, baby Duda, who is now 8 months old. Read the full story here.

For this senator, it’s personal

US Senator Bob Menendez (D-N.J.) has called for Congress to end its vacation early to pass Zika funding. And he has a personal investment in this case: His daughter, who lives in Miami, is five months pregnant with her first child and his first grandchild, he said at a recent press conference. “It seems to me that we are not doing enough to protect women like my daughter, before they get pregnant, during, and after.” (YouTube)

A drought, water politics, and Brazil’s Zika crisis

A prolonged drought and long-standing issues with its water infrastructure underlie Recife, Brazil’s Zika problem and why the area became a hotbed for the virus. In some neighborhoods, for example, the state utility agency runs water only a few times a week, and residents are left to store water in whatever containers they have, providing breeding grounds for mosquitoes. (Frontline)

Range at risk

Scientists have created a new model of where local Zika transmission might occur, taking into account both climate and socioeconomic factors. Blue areas are those considered most at risk in both dimensions.

The latest from Florida

Florida health officials are investigating an additional case of non-travel-related Zika infection in Miami-Dade County, which may suggest the outbreak is spreading beyond the Wynwood area.

Miami plans to begin aerial mosquito spraying in Wynwood, but that was delayed due to inclement weather today.

But the city is testing whether mosquitoes there have become resistant to common insecticides.

And outdoor activities in the Wynwood neighborhood, including the unfortunately named class “The Naked Bite,” are being moved or cancelled entirely.

After a mysterious case of Zika was found in Utah that may have been transmitted from a father to a son, health officials went door to door to solicit blood tests from nearly 100 neighbors, according to the Deseret News. All results have been negative so far, though, and CDC staffers that were deployed to help have now left Utah. Officials say their findings should be announced by early September.
