LACEY, Wash. 鈥 When her daughter was born at Providence St. Peter Hospital in January, the first thing Maria Rios checked was the baby鈥檚 head.
She鈥檇 seen the terrifying photos on the internet 鈥 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, U.S. doctors had told Rios 鈥 a 20-year-old, first-time mother 鈥 that she was infected with Zika, likely spread by a mosquito bite at her parents鈥 home in Colima, Mexico, last summer.
Rios desperately wanted them to be wrong.
鈥淚 saw that the babies had flat heads,鈥 she recalled. 鈥淎nd they had problems eating, seeing, talking, walking. They had seizures. I was just like, 鈥極h, God.鈥欌
But when Aryanna Guadalupe Sanchez-Rios arrived 鈥 5 pounds, 10 ounces, with a cap of straight, dark hair 鈥 it was clear that Rios’ fears had been realized. The baby鈥檚 head was far smaller than normal 鈥斅27 centimeters instead of the typical 35 centimeters 鈥斅燼 condition known as microcephaly. An early ultrasound of the baby’s brain showed extensive calcium deposits, more signs of Zika damage, doctors said.

Still, Rios refused to lose hope. To her, Aryanna鈥檚 head 鈥渨asn鈥檛 really flat,鈥 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鈥檚 wide, brown eyes already track light and motion.
鈥淚 just want her to be OK,鈥 Rios said.
Despite doctors鈥 warnings and medical facts, the young mother remains optimistic, relying on a deep Catholic faith to build a life for her daughter. As of May 23, Aryanna was born in U.S. states and Washington, D.C., with Zika-related birth defects.
Another eight pregnancy losses have been attributed to Zika infections, according to the Centers for Disease Control and Prevention, which updates counts regularly.
Aryanna, who was born in late January, 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.
鈥淎 lot of people ask for miracles,鈥 said Rios, who keeps a beaded bracelet with an amulet of the Blessed Virgin Mary on her daughter鈥檚 left wrist. 鈥淚 feel like you have to ask deep from your heart.鈥
To date, Rios is among nearly in U.S. states and the District of Columbia 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, 1 in 10 women in at least 44 states have had a baby with brain damage or other serious defects,

Rios was tested twice for Zika and told that she was free of infection. But days before Aryanna was born, a third test came back positive.
鈥淎 doctor told me, 鈥榊ou have Zika. That鈥檚 why your baby has microcephaly,鈥欌 Rios recalled. 鈥淪he could have said it a little bit nicer.鈥
After birth, Aryanna tested positive for the virus, too.
The news was devastating for Rios, a U.S. citizen who had been living with her husband and her parents in Colima, a city of more than 700,000 on the Pacific coast of Mexico. She had returned to the U.S. last fall to stay with family in Lacey, 90 minutes south of Seattle.
鈥淚 said, 鈥楬ow could that be possible?鈥 I didn鈥檛 have any symptoms,鈥 said Rios.
She found out only later that 4 of every 5 people infected with the Zika virus show no signs of the disease.
Even now, she finds it hard to believe that anything鈥檚 wrong. When Aryanna wakes from a nap, sleepy and warm, Rios swaddles her in a pink polka-dotted blanket and cradles her on the couch.
鈥淗i, Stinky! Hi, pretty girl!鈥 she croons, kissing Aryanna鈥檚 chubby cheek. 鈥淚 look at her like a normal baby.鈥
Rios and Aryanna are enrolled in the , 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鈥檛 found, 18 pregnant women have been identified with lab evidence of the virus since last year, said Hanna Oltean, an epidemiologist tracking Washington鈥檚 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.
鈥淭here鈥檚 been a definite learning curve in public health,鈥 Oltean said. 鈥淭his is the first mosquito-borne disease that has been anything like this.鈥

Dr. Hannah Tully, a pediatric neurologist at Seattle Children鈥檚 Hospital, 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.
鈥淶ika triggers this catastrophe of inflammation and cell death,鈥 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 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.
鈥淚t鈥檚 critically important that these babies be evaluated early,鈥 said Dr. Margaret Honein, chief of the CDC鈥檚 birth defects branch. 鈥淲e don鈥檛 yet know the full range of health problems these babies might have.鈥
It鈥檚 a crucial question, Honein added. Every week, another 30 to 40 cases are added to the pregnancy registry.
The full costs aren鈥檛 clear, either. In September, Congress allocated about to federal agencies for the Zika crisis. CDC has already 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 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.

The thought scares Rios, who shares a modest, two-bedroom apartment with her sister and brother-in-law. Aryanna鈥檚 condition means Rios can鈥檛 return to her former 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鈥 sister, Jessica Rios, 21, has been providing rides to medical appointments in Seattle. But her car broke down in May, forcing Maria Rios to scramble for last-minute transportation.
Rios gets formula from the federal , WIC, and Aryanna鈥檚 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 and the assistance hasn鈥檛 come through.
鈥淲here would I get $4 million?鈥欌 she said.
Rios was born in Auburn, Wash., and raised there until age 15, when she moved with her parents to Mexico to help take care of her ailing grandmother. She returned at 18 to finish high school. That鈥檚 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鈥檚 head lagged in development by two weeks, doctors weren鈥檛 concerned.
鈥淭hey said, 鈥極h, don鈥檛 worry,鈥欌 Rios recalled. 鈥淚n Colima, I didn鈥檛 see anybody alarmed about Zika.鈥
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 from 2015 through March 2.
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.

鈥淚 just hope he gets some sort of permission to be in the U.S.,鈥 Rios said. But, with a new president opposed to immigration in the White House, she said, she doubts that will happen soon.
Her husband met Aryanna in April, when Rios traveled with the baby back to Colima.
鈥淗e didn鈥檛 even know what Zika was,鈥 Rios recalled. 鈥淚 said, 鈥楲ook it up.鈥欌
Rios鈥 parents, both in their early 40s, couldn鈥檛 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鈥 father walked on his knees from the back to the altar, a gesture of faith aimed at keeping Aryanna safe from harm.
鈥淢y mom just keeps telling me, 鈥楨verything鈥檚 going to be fine,鈥欌 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鈥 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 鈥 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.
鈥淭here鈥檚 a chance her vision could be quite impaired,鈥 concluded Cabrera, who saw scarring on the baby鈥檚 retinas.
鈥淚 just want to know if she could wear glasses?鈥 Rios asked.
鈥淭his is a relatively new problem that we don鈥檛 understand well,鈥 Cabrera said, adding gently: 鈥淚 don鈥檛 think glasses are going to help.鈥
That news worried Rios. So did the results of the MRI, which confirmed Aryanna had brain damage from the effects of the Zika infection, 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.
鈥淚 try to be strong for her,鈥 Rios said, between sobs. 鈥淚鈥檓 really scared. It鈥檚 hard.鈥
The worst thing about Zika, she said, is that no one, not even the doctors, can tell her what鈥檚 next.
鈥淚 still have my hope,鈥 she said. 鈥淚鈥檓 trying everything for my girl to be OK.鈥
