There is a joke in New Mexico that the rest of the country does not know the state is part of the U.S. This summer, as cases of COVID-19 surged in many parts of the nation, New Mexico really did seem to stand apart. While Arizona and Texas, its neighbors to the west and east, loosened activity and business restrictions and then experienced alarming increases in COVID-19 numbers, New Mexico kept a tighter grip on the spread of the contagion. To date, Arizona has had more than twice as many cases and nearly twice as many deaths as New Mexico has per 100,000 people. The latter state also has far fewer cases and deaths per 100,000 than Texas.<\/p>\n
New Mexico\u2019s governor Michelle Lujan Grisham has taken an aggressive approach toward the pandemic. She declared a statewide emergency on March 11, the same day the state had its first positive case. She closed K\u201312 schools two days later, and quickly issued public health orders to limit public gatherings and shut down nonessential businesses. New Mexico began a widespread virus testing program for residents to curtail the spread (testing availability and delays are still problems in many other states). And on May 16 the state instituted a mask mandate. In June restaurants were allowed to open indoor dining at limited capacity, but in the middle of July permission was rescinded after an uptick in cases. As of September 7, the government has instructed all New Mexicans to \u201cstay home except for outings absolutely necessary for health, safety and welfare.\u201d These actions came with strong public health messages that explained how the moves curtailed disease spread.<\/p>\n
The reduction in disease can be seen in New Mexico\u2019s test results. The state has a goal of at least 5,000 assays per day and a 5 percent or less test positivity rate (a metric that reflects the amount of viral transmission). On September 11 the seven-day rolling averages of these two measurements were 4,896 tests daily and a 2.3 percent positivity rate. In comparison, Arizona and Texas had test positivity rates of 6.7 and 8 percent, respectively, at a similar time.<\/p>\n
These numbers, as well as the lower death rates, reflect what New Mexicans and their government had done to control infections in the previous months. \u201cWhatever they were doing in May and June looks like it worked a lot better than in Texas and some of these Sunbelt states,\u201d says Lauren Ancel Meyers, executive director of the University of Texas at Austin COVID-19 Modeling Consortium. David Scrase, secretary of New Mexico\u2019s Human Services Department and a physician at the University of New Mexico School of Medicine, agrees. \u201cWe have taken a more early and aggressive approach that\u2019s resulted in some real wins,\u201d he says.<\/p>\n
Testing has been a crucial part of New Mexico\u2019s strategy. Tests are available to all the state\u2019s residents, whether they are symptomatic or not, and are processed either at New Mexico\u2019s own laboratory or at TriCore Reference Laboratories, an independent organization based in Albuquerque. Both facilities were switched to 24\/7 work schedules very early on to maximize testing output. \u201cEighty percent of the testing is done right here in the state,\u201d Scrase says. \u201cWhen there was a huge backlog in national labs, that didn\u2019t affect us like it did other states,\u201d because New Mexico was not sending its assays elsewhere. Keeping the program local reduced the time required to transport tests for analysis.<\/p>\n
Another advantage for New Mexico is that it has a centralized public health agency, whereas Texas has a regionalized system. In the Lone Star State, that arrangement meant more variable policies and confusing public messaging. Having a centralized agency and a governor who is knowledgeable about disease prevention\u2014Lujan Grisham previously served as the state\u2019s secretary of health\u2014have made it easier for New Mexico to put together a consolidated effort to get things done, says David Morgan, media manager for the New Mexico Department of Health. Early in the spring, the state put together a team of 150 researchers and clinicians to advise its officials, and New Mexico has been \u201cvery proactive in implementing science-based decisions,\u201d says Sara Del Valle, a mathematical and computational epidemiologist at Los Alamos National Laboratory.<\/p>\n
Modeling the SARS-CoV-2 virus\u2019s transmission patterns is important for understanding ways of containing the outbreak. So in the spring New Mexico created its own modeling project in collaboration with researchers at Sandia National Laboratory and Los Alamos, as well as Presbyterian Healthcare Services, a nonprofit health care system in the state. The team produces several types of models. One is a forecasting model that intends to predict what will happen, given current trends, Del Valle says. The others assist with what-if scenarios to provide insights on how different possible decisions, such as limiting in-person school class size, might affect the virus\u2019s spread. \u201cWe\u2019ve been doing a lot of modeling on school reopening,\u201d Del Valle says. The researchers have also been assessing the impact of travelers in the state. Earlier this summer, New Mexico imposed a mandatory 14-day quarantine for most individuals coming in based on the models, and it is still required for people from areas with high numbers of cases.<\/p>\n
The state\u2019s models and its system for collecting and tracking data allow its policy makers to make forward-looking, evidence-based decisions, Scrase says. \u201cI have friends in other states working on this, and they feel like they\u2019re always reacting to the case counts, which are something that already happened. It\u2019s like driving this car 90 miles per hour\u2014only looking in the rearview mirror,\u201d he says.<\/p>\n
The scientists\u2019 work has not become politicized in the way such projects have in other states. In Arizona, the research team modeling the course of COVID-19 was instructed by Governor Doug Ducey\u2019s administration to halt its work in early May\u2014just as Ducey was directing widespread reopening around the state. The numbers that the team\u2019s models were providing \u201cdid not match the reopening approach,\u201d says University of Arizona infectious <\/strong>disease epidemiologist Saskia Popescu. She notes that Ducey\u2019s move was widely criticized as an attempt to suppress data that would contradict the reopening plans. The Arizona researchers were told to continue their work after widespread media coverage and public outcry.<\/p>\n In general, public pushback about activity restrictions in New Mexico has been more muted than in many other places. \u201cWe have our share of the political and cultural divide,\u201d says Jeff Dye, president of the New Mexico Hospital Association, but \u201cfor the most part, our state has been pretty supportive of our governor.\u201d According to a late July poll, Governor Lujan Grisham had a 53 percent approval rating for her handling of the COVID-19 pandemic.<\/p>\n There have been objections, however. In July the state notified the mayor of the small city of Grants that he was being fined $5,000 for refusing to adhere to its public health orders. The mayor, Martin Hicks, had held a Fourth of July parade in violation of state rules. Hicks is contesting the fine (a hearing is pending).<\/p>\n Despite all the precautions, one group that has been hit disproportionately hard by infections are Native Americans in the state. Although they represent only 11 percent of the state\u2019s population, they accounted <\/strong>for more than half of the state\u2019s initial cases, according to a report published in June. One likely reason is that multigenerational households are common among this group. Disease models from Del Valle\u2019s team indicate that larger households, packed into smaller spaces, make it easier for the virus to spread.<\/p>\n New Mexico\u2019s 22 Native American nations and tribes <\/strong>have met with Lujan Grisham and other agency leaders from the onset, says Brian Vallo, governor of the Pueblo of Acoma, which is one of them. Vallo issued a declaration of public health crisis on March 13 and closed the pueblo\u2019s borders. In May, the state responded to an outbreak in the Navajo Nation by closing all roads coming into the city of Gallup, which serves as a gateway to nearby Native American jurisdictions. The Navajo Nation itself instituted strict health mandates such as mask wearing, stay-at-home orders and weekend lockdowns to contain the virus. \u201cThese efforts have significantly contributed toward our management of the virus and its impact on the community,\u201d Vallo says. In early September the Navajo Nation reported its first period without a new case. And Michael Weahkee, director of the Indian Health Service, told the Navajo Times<\/em> that not only had the nation flattened the curve, but it was \u201con the downhill slope.\u201d<\/p>\n The state works with Native American groups to provide food and shelter to people who need to quarantine because of COVID-19 or who have lost income, Scrase says. The government set up housing in hotels, for example. Vallo says the Pueblo of Acoma has a \u201cvery strong relationship\u201d with Governor Lujan Grisham\u2019s office and her cabinet.<\/p>\n School openings have been a concern in the state, as they have all over in the U.S., and overall low case numbers have allowed New Mexico schools to begin reopening. Some did so with a remote-learning format in August, but the state has now given the go-ahead to school districts and charter schools in 25 counties to allow limited cohorts of students to rotate between remote and in-person learning. Small cohorts are used to reduce the number of students in a classroom at the same time and to maintain social distancing. In order to move to hybrid learning, schools must be located in counties with low rates of positive tests and new daily cases that follow below thresholds established by the New Mexico Department of Health. (As of September 9, most of the state qualified.) Schools must also have an approved plan to address instructional, social-emotional and family engagement. And they need to have comprehensive safety and cleaning protocols in place, as well as rapid response plans in the event of a positive case.<\/p>\n Ultimately, the focus on science may be the biggest factor in New Mexico\u2019s resilience. Del Valle says the state has been \u201cvery proactive at implementing science-based decisions.\u201d Scrase adds that \u201cit\u2019s really exciting to have a governor who values science and evidence.\u201d Reopening decisions did take economic interests into account, he notes, but ultimately, they were driven by data about health and safety. \u201cI\u2019m really proud of that,\u201d he says.<\/p>\n Read more about the coronavirus outbreak from Scientific American here.
