Latest COVID strain doesn’t appear to pose a threat in Las Vegas Valley

Latest COVID strain doesn’t appear to pose a threat in Las Vegas Valley


Wastewater is an early warning system for COVID and other diseases, and a collaborative effort in Nevada appears to be the first in the nation to detect a new strain of the disease — known as FLiRT.

“We detected it as early as March 29,” said UNLV Professor Dr. Edwin Oh, director of the UNLV lab that monitors wastewater in southern and northern Nevada, adding that his check of various websites from labs across the country that do such wastewater monitoring, indicates UNLV was first in finding the new variant.

The goal of the wastewater surveillance and research is to determine if any new strain of the constantly evolving disease — that once killed 25,000 Americans a week at its height in 2020 — might pose a problem for humans.

“So far it does not look like it (FLiRT) poses any major threats,” Oh said of the the two variants — KP.1 and KP.2. — that are mutations of FLiRT.

“We nerd out a lot on the different pathogens and variants,” Oh said of his crew that includes UNLV undergrads and wastewater treatment plant operators. About 15 different sites are checked weekly in Clark County and three or four sites in Northern Nevada.

The effort is to warn and protect the community from COVID variants that could raise the risk of major sickness potential.

Genetic material from the virus that causes COVID-19 can be found in human waste even when individuals have no symptoms. Tracking the amount of viral genetic material (viral load) in wastewater is an emerging method of monitoring increasing and decreasing trends of the virus in communities.

Wastewater surveillance has been ongoing for years. The most recent variant that raised eyebrows was JN.1 around Christmas time, Oh said. “It had about 50 mutations and a lot of us were concerned that it might bring added risk to the immunocompromised (population) or the vaccine resistant (population).”

The wastewater monitoring project is a collaboration between Southern Nevada Health District, Southern Nevada Water Authority, Desert Research Institute and UNLV.

Earthquake swarm rattles central Nevada near Tonopah along newly identified fault

Earthquake swarm rattles central Nevada near Tonopah along newly identified fault


A swarm of earthquakes has been rattling a remote stretch of central Nevada near Tonopah, including a magnitude 4.0 quake that hit near Warm Springs Tuesday morning.

Seismologists said the activity is typical for Nevada, where clusters of earthquakes can flare up in a concentrated area. “This is a very Nevada-style earthquake sequence. We have these a lot where we just see an uptick in activity in a certain spot,” said Christie Rowe, director of the Nevada Seismological Lab.

The latest magnitude 4.0 quake struck east of Tonopah near Warm Springs. The largest earthquake in the swarm so far has measured a 4.2.

What has stood out to researchers is the fault involved. Rowe said the earthquakes are occurring along a fault stretching along the southern edge of the Monitor and Antelope ranges — and that it was previously unknown to scientists. “We didn’t know this fault was there. It’s a new fault to us — not to the Earth, obviously — but it was previously unknown,” Rowe said.

For now, the earthquakes have remained moderate. Rowe said the lab would not deploy additional temporary sensors unless activity increases to around a magnitude 5 or greater.

Seismologists said they are continuing to watch the swarm closely as Nevada works to bring the ShakeAlert early warning system to the state. The program, already active in neighboring states, can send cellphone alerts seconds before shaking arrives. “For me, it’s a really high priority. That distance to the faults gives us enough time to warn people — and that can make a big difference in reducing injuries and damage,” Rowe said.

Seismologists encouraged anyone who feels shaking to report it through the U.S. Geological Survey’s “Did You Feel It” system, saying even small quakes can help scientists better understand Nevada’s seismic activity.

Experts said the swarm is worth monitoring but is not cause for alarm. They noted that earthquakes like the 5.8 that hit near Yerington in December 2024 typically happen in Nevada about every eight to 10 years, and said they will continue monitoring the current activity closely.

Kalshi Enforcement Action Belongs in Nevada Court, Judge Says


Nevada state court is the proper venue for reviewing whether KalshiEX LLC is improperly accepting sports wagers without a license, a federal district court said.

The Nevada Gaming Control Board showed that the state statutes under which it seeks relief don’t require interpreting federal law, Judge Miranda M. Du of the US District Court for the District of Nevada said in a Monday order. The board’s action is now remanded to the First Judicial District Court in Carson City, Nev., the order said.

The board in 2025 urged Kalshi, a financial services company, to get a gaming license, but the …

EDITORIAL: Nevada still vulnerable as tourist downturn continues


Strip gaming executives can put their best spin on the numbers, but local tourism indicators remain a major concern. Casino operators seeking to draw more people through the door still have much work to do.

The Nevada Gaming Control Board released January gaming numbers Friday. The news was underwhelming. The state gaming win was down 6.6 percent from a year earlier. The Strip took the largest hit, an 11 percent drop. But the gloomy returns were spread throughout Clark County: Downtown Las Vegas was off 5.2 percent, Laughlin suffered a 3.3 percent decline and the Boulder Strip dipped by 7 percent.

For the current fiscal year, gaming tax collections are up a paltry
2.1 percent, below budget projections.

The red flags include more than gaming numbers. Recently released figures for 2025 reveal that visitation to Las Vegas fell nearly 8 percent from 2024, which represented the lowest total since the pandemic in 2021. Traffic at Reid International Airport fell more than 10 percent in December and was down 6 percent for the year. Strip occupancy rates fell 3 percent in 2025.

To be fair, this is not just a Las Vegas problem. International travel to the United States was down
4.8 percent in January, Forbes reported, the ninth straight month of decline. Travel from Europe fell 5.2 percent, and passenger counts from Asia fell 7.5 percent. Canadian tourism cratered by 22 percent.

No doubt that President Donald Trump’s blustery rhetoric has played a role in the decline, but there’s more at work. International tourism has been largely flat since Barack Obama’s last few years in office. But domestic travel has held relatively steady although it is “starting to cool,” according to the U.S. Travel Association. Las Vegas hasn’t been helped by high-profile complaints last year about exorbitant Strip prices for parking, bottled water and other staples. Casino operators responded by offering discounts, particularly for locals, and they’ll need to continue those policies into 2026.

The tourism downturn has ramifications for the state budget, which relies primarily on sales and gaming tax revenues to support spending plans. “Nevada’s employment and economic challenges reflect deep structural factors that extend beyond cyclical economic fluctuations,” noted a recent report by economic analyst John Restrepo. “The state’s extreme concentration in tourism and gaming creates unique vulnerabilities.”

The irony is that state and local politicians have been talking for the past half century about “diversifying” the state economy. In recent years, that effort has primarily consisted of handing out millions in tax breaks and other incentives to attract businesses to the state. A dispassionate observer might ask whether that approach has brought an adequate return on investment.
