So far, 72 affected babies have been born in the U.S. One young Puget-Sound-area mother, infected with the Zika virus while she was in Mexico last year, and her infant daughter face a complicated future.
LACEY — When her daughter was born at Providence St. Peter Hospital in January, the first thing Maria Rios checked was the baby’s head.
She’d seen the terrifying photos on the internet — infants in Brazil and in Puerto Rico whose skulls were misshapen, even collapsed, ravaged by the Zika virus that has engulfed Latin America.
Days earlier, doctors had told Rios — a 20-year-old, first-time mother — that she was infected with Zika, likely spread by a mosquito bite when she and her husband were living last summer at her parents’ home in Colima, Mexico.
• Zika is spread mostly by the bite of an infected Aedes species mosquito.
• Zika can be passed from a pregnant woman to her fetus. Infection during pregnancy can cause certain birth defects. Pregnant women should not travel to areas with risk of Zika,
• Zika can be passed through sex from a person with Zika to his or her partners.
• There is no vaccine or medicine for Zika.

“I saw that the babies had flat heads,” she recalled. “And they had problems eating, seeing, talking, walking. They had seizures. I was just like, ‘Oh, God.’”

When Aryanna Guadalupe Sanchez-Rios arrived — 5 pounds, 10 ounces, with a cap of straight, dark hair — it was clear Rios’ fears had been realized. The baby’s head was small — 27 centimeters instead of the typical 35 — a condition known as microcephaly. An ultrasound showed extensive calcium deposits on the brain, more Zika evidence.
The news was devastating for Rios, who was born and raised in Auburn and returned to the U.S. last fall to stay with family in Lacey.
As of May 23, Aryanna was one of 72 babies born in the U.S. with Zika-related birth defects. Another eight pregnancy losses have been attributed to Zika infections, according to the Centers for Disease Control and Prevention (CDC), which updates counts regularly.
Rios refuses to lose hope about her baby. Despite doctors’ warnings and medical facts, the young mother remains optimistic, relying on a deep Catholic faith to build a life for her daughter.
To her, Aryanna’s head “wasn’t really flat,” just small, she said. Eye exams showed scarring in the center of the retinas, a likely sign of vision loss caused by the virus. But Rios is certain her baby’s wide, brown eyes already track light and motion.
“I just want her to be OK,” Rios said.
Aryanna and the other infants are now at the center of efforts by U.S. officials to monitor the lasting effects of the devastating outbreak, even as another dangerous mosquito season begins.
“A lot of people ask for miracles,” said Rios, who keeps a beaded bracelet with an amulet of the Blessed Virgin Mary on her daughter’s left wrist. “I feel like you have to ask deep from your heart.”
To date, Rios is among nearly 1,900 pregnant women in the U.S. with laboratory evidence of possible Zika virus infections, according to the CDC. Nearly 1,600 have completed their pregnancies.
Of those with confirmed Zika infections in the U.S. last year, 1 in 10 women had a fetus or baby with brain damage or other serious defects, a recent CDC analysis showed.
Rios was tested twice for Zika and told she was free of infection. But days before Aryanna was born, a third test came back positive.
“A doctor told me, ‘You have Zika. That’s why your baby has microcephaly,’” Rios recalled. “She could have said it a little bit nicer.”
After birth, Aryanna tested positive for the virus, too.
“I said, ‘How could that be possible?’ I didn’t have any symptoms,” said Rios.
She found out only later that four of every five people infected with the Zika virus show no signs of the disease.
Even now, she finds it hard to believe that anything’s wrong. When Aryanna wakes from a nap, sleepy and warm, Rios swaddles her in a pink polka-dot blanket and cradles her on the couch.
“Hi, Stinky! Hi, pretty girl!” she croons, kissing Aryanna’s chubby cheek. “I look at her like a normal baby.”
Rios and Aryanna are enrolled in the U.S. Zika Pregnancy Registry, where state and local health departments are tracking women and infants with laboratory evidence of infection.
Even in Washington, a low-risk state where the Aedes aegypti and Aedes albopictus mosquitoes that spread Zika aren’t found, 18 pregnant women have been identified with lab evidence of the virus since last year, said Hanna Oltean, an epidemiologist tracking Washington’s cases. All appear to have acquired the virus through travel, though Zika can be transmitted through sex as well.
Of those local women, three have delivered babies with microcephaly, including Rios.
“There’s been a definite learning curve in public health,” Oltean said. “This is the first mosquito-borne disease that has been anything like this.”
Dr. Hannah Tully, a pediatric neurologist at Seattle Children’s, examined Aryanna five weeks after birth and again this month. An expert in microcephaly, Tully has seen many children with the disorder, but Zika is different, she said. The damage appears to be greater than that typically found when microcephaly is caused by other conditions, including infections and premature birth.
“Zika triggers this catastrophe of inflammation and cell death,” Tully said.
Scientists now know that Zika, a once-obscure virus, targets and attacks neural stem cells in the developing fetal brain. Babies born with congenital Zika syndrome often have severe microcephaly, diminished brain tissue and eye damage, as well as restricted joint movement and rigid muscle tone. Recent research suggests they also might suffer hearing problems and seizure disorders, such as epilepsy.
“It’s critically important that these babies be evaluated early,” said Dr. Margaret Honein, chief of the CDC’s birth defects branch. “We don’t yet know the full range of health problems these babies might have.”
It’s a crucial question, Honein added. Every week, another 30 to 40 cases are added to the pregnancy registry.
‘Where would I get $4 million?’
The full costs aren’t clear, either. In September, Congress allocated about $1.1 billion in emergency funding to federal agencies for the Zika crisis. CDC already has spent about $300 million in redirected funds and has designated about $394 million more, according to an agency spokeswoman.
The White House budget released in May proposes establishing an emergency fund to pay for responses to emerging outbreaks like Zika. But it also would cut $1.3 billion from the CDC and $838 million from the National Institute of Allergy and Infectious Diseases, where scientists are working on a vaccine to prevent Zika infection.
And none of that funding covers what it may take to raise children like Aryanna.
One new estimate led by researchers at Yale University and the Johns Hopkins Bloomberg School of Public Health pegs the medical and other expenses for a Zika-affected child at $4.1 million over a lifetime. Previous CDC estimates have been as high as $10 million.
The thought scares Rios, who shares a modest, two-bedroom apartment with her sister and brother-in-law. Aryanna’s condition means Rios can’t return to her job as a receptionist for a packaging firm, so she relies on family for rent, food, diapers, clothes and transportation.
That assistance is precarious, too. Rios’ sister, Jessica Rios, 21, has been providing rides to medical appointments in Seattle. But her car broke down in May, forcing Maria to scramble for last-minute transportation.
Rios gets formula from the federal Women, Infants and Children’s program, WIC, and Aryanna’s medical care is covered by Medicaid, the state and federal program for poor and disabled people. Rios has applied for Social Security disability benefits, but the process is long.
“Where would I get $4 million?’” she said.
When Rios was 15, she moved with her parents to Mexico to help take care of her ailing grandmother. She returned at 18 to finish high school. That’s when she met her husband, Julio Sanchez, 26, who was working in the U.S. as a landscaper on a temporary visa.
The pair dated, fell in love and married in September 2015. They moved to Colima three months later, in December, after his visa expired, just after the first three cases of Zika infection were reported in Mexico.
Rios discovered she was pregnant in April 2016; doctors initially thought she had a cyst on an ovary. Sudden bleeding put Rios on bed rest for five months, and she spent that time worried more about miscarriage than any mosquito-borne virus.
Even when an ultrasound at six months showed that the baby’s head lagged in development by two weeks, doctors weren’t concerned.
“They said, ‘Oh, don’t worry,’” Rios recalled. “In Colima, I didn’t see anybody alarmed about Zika.”
In February, Mexican health officials reported that Colima is now one of four states in the country with the highest incidence of Zika infections, with 189 cases confirmed in pregnant women from 2015 through March 2 of this year.
‘I’m really scared’
Rios wanted to give birth in the U.S. to ensure that her daughter would be a citizen and to receive proper care, even though it meant leaving her husband behind. She texts him constantly, sending photos of Aryanna in a flower-print onesie and Minnie Mouse pajamas.
“I just hope he gets some sort of permission to be in the U.S.,” Rios said. But with the new president, she said, she doubts that will happen soon.
Her husband met Aryanna in April, when Rios traveled with the baby back to Colima.
“He didn’t even know what Zika was,” Rios recalled. “I said, ‘Look it up.’”
Rios’ parents, both in their early 40s, couldn’t hide their concern for their daughter and their first grandchild.
The family drove straight from the airport with the baby to a church in Talpa de Allende, where Rios’ father walked on his knees from the back to the altar, a gesture of faith aimed at keeping Aryanna safe from harm.
“My mom just keeps telling me, ‘Everything’s going to be fine,’” Rios said.
Sometimes, Rios is not so sure. Her days revolve around Aryanna, who receives weekly visits from a public health nurse and a physical therapist and has doctors’ appointments lined up six months in advance.
The baby endured a nine-hour round of medical tests on a recent Friday, including neurological and eye exams and an MRI. Aryanna was patient while a technician measured her head — 33.2 centimeters. At 3 months, it was still smaller than a typical newborn measurement of 35 centimeters.
But the child screamed in outrage as Dr. Michelle Trager Cabrera, a pediatric ophthalmologist, shined a bright light and peered deeply into her dark eyes.
“There’s a chance her vision could be quite impaired,” concluded Cabrera, who saw scarring on the baby’s retinas.
“I just want to know if she could wear glasses?” Rios asked.
“This is a relatively new problem that we don’t understand well,” Cabrera said, adding gently: “I don’t think glasses are going to help.”
That news worried Rios. So did the results of the MRI, which confirmed Aryanna had brain damage, Rios said.
At the hospital, Rios asked her sister to watch the baby for a minute and stepped outdoors into a hospital atrium.
She sat down at a table, placed her head in her hands and started to cry.
“I try to be strong for her,” Rios said, between sobs. “I’m really scared. It’s hard.”
The worst thing about Zika, she said, is that no one, not even the doctors, can tell her what’s next.
“I still have my hope,” she said. “I’m trying everything for my girl to be OK.”
