This 9171 subtype “continues, unfortunately uninterrupted, across multiple jurisdictions,” David Sugerman, who leads the CDC measles response, said on the call.
According to the Times, local health officials are pessimistic that they’ll be able to stamp out the virus’s spread, saying that vaccination efforts have had “limited” impact. As Ars reported previously, vaccination rates are dangerously low in two measles hotspots: northwestern Mohave County, Arizona, and the southwest health district of Utah. Vaccination rates among kindergartners in the 2024–2025 school year were 78.4 percent and 80.7 percent, respectively. That’s well below the 95 percent target needed to keep the virus from spreading onward in the communities.
In addition, public health officials in Arizona and Utah have reported barriers to responding to the outbreak. Around a quarter of cases don’t know how they were exposed, suggesting cases and exposures are being missed. In late October, health officials in Salt Lake County, Utah, said that a person likely infected with measles refused to cooperate with their investigation, leaving them unable to confirm the probable case.
David Kimberlin, who sits on a panel of experts that analyzes measles data for the United States’ elimination status review, told the Times, “It would not surprise me in the least if there’s continued spread across these next several months.”
To date, the CDC has tallied 1,723 measles cases across 42 states. Most (87 percent) of those cases were linked to outbreaks, of which there have been 45 this year. For context, there were 16 outbreaks and a total of 285 measles cases in the US last year. This year’s measles cases mark a 33-year high.
A measles investigation amid a large, ongoing outbreak at the Arizona-Utah border has hit a roadblock as the first probable case identified in the Salt Lake City area refuses to work with health officials, the local health department reported this week.
There have been over 150 cases collectively across the two states, mostly in northwestern Mohave County, Arizona, and the southwest health district of Utah, in the past two months. Both areas have abysmally low vaccination rates: In Mohave County, only 78.4 percent of kindergartners in the 2024–2025 school year were vaccinated against measles, according to state records. In the southwest district of Utah, only 80.7 percent of kindergartners in the 2024–2025 school year had records of measles vaccination. Public health experts say vaccination coverage of 95 percent is necessary to keep the disease from spreading in a community.
While the outbreak has largely exploded along the border, cases are also creeping to the north, toward Salt Lake County, which encompasses the city. Utah County, which sits just south of Salt Lake County, has identified eight cases, including a new case reported today.
Uncooperative case
Salt Lake County likely has a new one, too—the first for the county this year—as well as possible exposures. But, they can’t confirm it.
County health officials said that a health care provider in the area contacted them late on Monday to tell them about a patient who very likely has measles. The officials then spent a day reaching out to the person, who refused to answer questions or cooperate in any way. That included refusing to share location information so that other people could be notified that they were potentially exposed to one of the most infectious viruses known.
“The patient has declined to be tested, or to fully participate in our disease investigation, so we will not be able to technically confirm the illness or properly do contact tracing to warn anyone with whom the patient may have had contact,” Dorothy Adams, executive director of Salt Lake County Health Department, said in a statement. “But based on the specific symptoms reported by the healthcare provider and the limited conversation our investigators have had with the patient, this is very likely a case of measles in someone living in Salt Lake County.”
Enlarge/ US President Joe Biden speaks during a “First Tool-In” ceremony at the Taiwan Semiconductor Manufacturing Co. facility under construction in Phoenix, Arizona, US, on Tuesday, Dec. 6, 2022. TSMC today announced plans to boost its investment in the state to $40 billion and construct a second production facility, following major customers urging the Taiwanese chipmaker to build more advanced semiconductors in the US.
President Joe Biden’s plan to expand America’s command of the global chips market hit another setback Thursday when Taiwan Semiconductor Manufacturing Company (TSMC) Chairman Mark Liu announced that he anticipates significant delays at the company’s second chips plant in Arizona.
This news follows previous delays announced last year at TSMC’s first chips plant, which Liu partly blamed on US workers lacking specialized skills. At Thursday’s news conference, Liu “reiterated” those complaints, Bloomberg reported, claiming that TSMC is still struggling to hire skilled workers in Arizona.
According to Liu, TSMC’s second Arizona plant—which is supposed to become the most advanced facility in the US—likely won’t start volume production of advanced chips until 2027 or 2028. That’s potentially two years longer than initial projections suggesting that production would start in 2026.
Such lengthy delays, Bloomberg noted, might be “time enough for semiconductor tech to advance by one generation.” If that’s the case, one of the country’s biggest foreign investments ever might result in the US still lagging behind foreign chips competitors.
Liu also suggested that the second plant, even with delays, might not start producing the 3-nanometer chip that TSMC had earlier stated would be possible in 2026. This 3-nm chip is “among the most advanced” chips manufactured today, The Wall Street Journal noted, but Liu said that until TSMC could calculate “customer demand and government incentives,” the chipmaker wouldn’t be able to determine “the specific chip type” that the second plant would begin producing as late as 2028.
TSMC’s delays could be due to a lack of Chips Act funding, Bloomberg suggested, pointing out that none of the leading chip manufacturers ramping up efforts in the US today have been approved for funding yet by the Department of Commerce.
Last month, Commerce Secretary Gina Raimondo confirmed that the US had not yet awarded grants to commercial semiconductor facilities like TSMC because selecting a defense contractor first “was meant to emphasize the administration’s focus on national security,” The New York Times reported. By funding BAE Systems, the Biden administration was likely moving quickly to decrease reliance on China-based chip supply chains for military purposes amid growing tensions between the two countries.
“When we talk about supply chain resilience, this investment is about shoring up that resilience and ensuring that the chips are delivered when our military needs them,” Jake Sullivan, President Biden’s national security adviser, said last month.
If the US announced funding for TSMC, that could ensure that the second Arizona chips plant would be operational by 2027 rather than 2028. According to Bloomberg, TSMC announced it was building a “more modest plant” in Japan that’s on track to launch operations this year after the Japanese government promptly provided funding.
In December, Raimondo promised that “much larger grants for major semiconductor manufacturing facilities run by companies like Intel, Samsung,” or TSMC would be announced “in the coming months.” She also confirmed that the “pace” of announcing awards would speed up in the first half of 2024.
Liu said that TSMC is in “consistent communication with the US government on incentive and tax credit support” in Arizona, the Journal reported.
