Wild migratory birds likely spread a deadly strain of bird flu to dairy cows in Texas and Kansas, state and federal officials announced this week.

It is believed to be the first time the virus, a highly pathogenic avian influenza (HPAI), has been found in cows in the US. Last week, officials in Minnesota confirmed finding an HPAI case in a young goat, marking the first time the virus has been found in a domestic ruminant in the US.

According to the Associated Press, officials with the Texas Animal Health Commission confirmed the flu virus is the Type A H5N1 strain, which has been ravaging bird populations around the globe for several years. The explosive, ongoing spread of the virus has led to many spillover events into mammals, making epidemiologists anxious that the virus could adapt to spread widely in humans.

For now, the risk to the public is low. According to a release from the US Department of Agriculture (USDA), genetic testing by the National Veterinary Services Laboratories indicated that H5N1 strain that spread to the cows doesn’t appear to contain any mutations that would make it more transmissible to humans. Though the flu strain was found in some milk samples from the infected cows, the USDA emphasized that all the milk from affected animals is being diverted and destroyed. Dairy farms are required to send only milk from healthy animals to be processed for human consumption. Still, even if some flu-contaminated milk was processed for human consumption, the standard pasteurization process inactivates viruses, including influenza, as well as bacteria.

So far, officials believe the virus is primarily affecting older cows. The virus was detected in milk from sick cows on two farms in Kansas and one in Texas, as well as in a throat swab from a cow on a second Texas farm. The USDA noted that farmers have found dead birds on their properties, indicating exposure to infected birds. Sick cows have also been reported in New Mexico. Symptoms of the bird flu in cows appear to include decreased milk production and low appetite.

But so far, the USDA believes the spread of H5N1 will not significantly affect milk production or the herds. Milk loss has been limited; only about 10 percent of affected herds have shown signs of the infection, and there has been “little to no associated mortality.” The USDA suggested it will remain vigilant, calling the infections a “rapidly evolving situation.”

While federal and state officials continue to track the virus, Texas officials aim to assure consumers. “There is no threat to the public and there will be no supply shortages,” Texas Agriculture Commissioner Sid Miller said in a statement. “No contaminated milk is known to have entered the food chain; it has all been dumped. In the rare event that some affected milk enters the food chain, the pasteurization process will kill the virus.”

Fourteen states have banned abortions at any gestational age since the Supreme Court overruled Roe v. Wade in 2022. Since the enactment of those abortion bans, an estimated 64,565 people became pregnant as a result of rape in those states. But, while five of the 14 states have exceptions for rape, all of the states logged only 10 or fewer legal abortions per month since their respective bans were enacted.

The finding, published this week in JAMA Internal Medicine, is a stark look at the effects of such bans on reproductive health care. The study did not assess how many of the estimated 64,565 pregnancies resulted in births, but it makes clear that tens of thousands of pregnant rape survivors, including children, were forced to turn to illegal procedures, self-managed abortions, or burdensome travel to states where abortion is legal—cost-prohibitive to many—as an alternative to carrying a rape-related pregnancy to term.

It also showed that legal exceptions for rape don’t work. The states with those exceptions apply stringent time limits on the pregnancy and require victims to report their rapes to law enforcement, which likely disqualifies most. The US Department of Justice estimates that only 21 percent of victims report their rape to police, for myriad reasons.

In an editor’s note accompanying the study, a trio of JAMA Internal Medicine editors—who are also medical researchers at the University of California, San Francisco, Harvard, and NYC Health and Hospitals—note the findings “demonstrate the scope of the problem,” as the number of rape-related pregnancies is “exponentially larger” than the number of legal abortions in those states.

“As physicians, we do not see abortion as a political, religious, or legal issue. Rather we see access to safe abortions as a necessary part of reproductive health services to protect the physical and mental well-being of patients. The best solution to this problem is a national law protecting the right of all people to choose to terminate pregnancy,” they write.

Study design

The study, led by a researcher at Planned Parenthood of Montana, is only an estimate because hard, state-level numbers are impossible to come by. The researchers pulled rape data from the DOJ’s Bureau of Justice Statistics, the FBI, and the Centers for Disease Control and Prevention’s National Intimate Partner and Sexual Violence survey, a specially designed survey to ascertain reported and unreported rapes.

With national data from various sources, the researchers estimated the proportion of rape survivors that are female individuals ages 15 to 45, and they further adjusted for the number of rapes that are vaginal. To estimate state-level rapes, they proportioned the rapes by states based on the FBI’s 2022 crime data, which includes rapes. They then multiplied each state’s rapes by the fraction of rapes likely to result in pregnancy. And finally, adjusted for the months between July 1, 2022 and January 1, 2024 that an abortion ban was in effect in each of the 14 states. Among the 14 states, the number of months in which a ban was in effect ranged from four to 18 months.

In all, the researchers estimated 519,981 completed vaginal rapes in the 14 abortion ban states which resulted in a collective total of 64,565 pregnancies during the four to 18 months that bans were in effect. Of the rape-related pregnancies, an estimated 5,586 (9 percent) were in states with rape exceptions, and 58,979 (91 percent) were in states with no exception.

Texas, the abortion-ban state with the largest population, had an estimated 26,313 (41 percent) of all rape-related pregnancies under its ban, which was enacted for 16 months during the study time frame. The state’s large number drew outrage from Democratic state lawmakers, particularly in light Gov. Greg Abbott’s vow to “eliminate rape” in Texas after a 2021 six-week abortion ban took effect (the state enacted a total ban in August 2022).

“Women and girls across our state are enduring unwanted pregnancies, suffering from life-endangering complications in desired pregnancies and fleeing the state for medical care,” the 13 Democratic state senators said in a Thursday news release, as reported by the Houston Chronicle. “We cannot allow this to be the new norm.”
