Some only lived minutes; others died within days or weeks.
The cause: congenital syphilis.
They are all born to mothers with syphilis. Many of the mothers arrive at the hospital to give birth never having had prenatal care, unaware they have the disease -- let alone that they could pass it along to their unborn babies. The infants who survive carry an elevated risk of long-term health problems.
"It's been an absolute explosion," said Khurana, who works at four hospitals in California's Central Valley. "It's just spreading very, very quickly. Kern County has a huge public health problem on its hands."
The Central Valley -- a vast agricultural and mostly low-income swath of California -- has seen an unprecedented spike in congenital syphilis
over the last few years. It's part of an overall rise in syphilis
and other sexually transmitted diseases across California and the nation.
Health professionals fear rates could rise even further if President Donald Trump and the Republican Congress repeal the Affordable Care Act and people lose access to reproductive health care.
"STD rates aren't going to just stop," said Natasha Felkins, a health educator for Planned Parenthood in Bakersfield, the main city in Kern County. "When health coverage goes away or when things are cut, we are going to see numbers increase and that's going to affect all of us."
Across the U.S., sexually transmitted diseases are at an all-time high, according to the Centers for Disease Control and Prevention
. The rate of syphilis among women increased 27 percent from 2014 to 2015, and congenital syphilis increased by 6 percent. Preliminary data show the trend continued into 2016, with syphilis among women rising another 21 percent and congenital syphilis 4 percent.
The rise is worrisome, especially given that syphilis had almost disappeared by about 2000, said Gail Bolan, director of the CDC's division of sexually transmitted disease prevention.
"There was great hope for syphilis elimination in the United States," Bolan said. "Unfortunately, our national data now show that syphilis is thriving."
Bolan said CDC officials are closely monitoring the epidemic of syphilis around the nation, urging states to explore the roles of poverty, limited health care access, drugs and incarceration and to address those factors. They are watching with particular concern the spike in cases among women, and encouraging more testing, treatment and education.
"Rises in women, especially women of reproductive age ... are a bellwether for when we are going to start seeing more congenital syphilis," Bolan said.
In California, about two-thirds of syphilis cases are still among men who sleep with men, but the number of cases among women between the ages of 15 and 44 quadrupled from 2011 to 2015, according to the state Department of Public Health. And cases of congenital syphilis increased threefold over that same time period.
In 2015, nearly half of them were in Fresno and Kern counties. Kern County had 28 cases of congenital syphilis in 2015, up from one in 2011. Nearby Fresno County had 40 in 2015, up from two four years earlier. The rates in both counties dwarf others around the state.
California's rate of syphilis among newborns is the second highest in the U.S. after Louisiana, and the state ranks third after Louisiana and Georgia for syphilis among women, according to the CDC.
Louisiana stepped up its response to the increase about four years ago, working with the CDC to expand testing sites, raise public awareness and increase education for OB-GYNs. Over the past year, the state also started nine regional STD task forces to address the problem. And the state passed legislation mandating syphilis testing twice during pregnancy.
Congenital syphilis cases now are starting to decline, said DeAnn Gruber, director of the infectious diseases bureau for the Louisiana Department of Health.
