Coronavirus in Nevada

Tracking vaccinations, cases through data


Updated July 27, 2021 - 5:26 am

The state’s COVID-19 cases are on the rise again this winter, as the highly contagious omicron variant accounts for more infections.

Indoor mask mandates remain in counties with high levels of disease transmission.

After a fall dominated by the delta variant, Nevada and the U.S. are seeing a growing number of cases attributed to the omicron variant.

The new variant is reportedly even more contagious than delta, which itself was described as “probably the second-most infectious disease we’ve seen in the past 100 years” by Dr. Cassius Lockett of the Southern Nevada Health District.

However, recent studies have also suggested that the omicron variant casues less severe disease than delta.

The Centers for Disease Control and Prevention is monitoring levels of COVID-19 transmission in counties across the U.S.

Nevada officials have said they will mandate indoor mask wearing in counties experiencing “substantial” or “high” transmission for two weeks in a row.

In counties that sustain lower levels of transmission, the mask requirement will only apply to unvaccinated individuals.

Nevada’s test positivity rate remains well above 5 percent – the optimal goal set by the World Health Organization.

The rate is calculated by dividing positive tests by the total number of tests administered. State officials measure the average rate of the past 14 days, with test results reflecting the date the testing specimen was collected.

Breakthrough cases of COVID-19 in fully vaccinated Nevadans are on the rise.

Health experts have said they expect breakthrough cases to rise as more of the population gets vaccinated, but they have stressed that hospitalizations and deaths from breakthrough cases remain rare.

Hospitalizations among people infected with COVID-19 have remained relatively steady since late October.

The vast majority of recent hospitalizations and deaths are reported to have been among the unvaccinated.

Nevada measures what portion of its staffed acute-care hospital beds are currently full. It also measures the number of licensed intensive care unit beds that are full.

However, certain hospitals in Southern Nevada have reported nearing or reaching their max capacity in recent weeks.

In addition to COVID-19 patients, the hospitals are also treating people who delayed seeking care or had surgeries postponed earlier in the pandemic.

The data below is updated weekly. It represents the previous week’s hospital capacity.

The Centers for Disease Control and Prevention reports that vaccines currently available in the U.S. “are expected to protect against severe illness, hospitalizations, and deaths due to infection with the omicron variant.”

Proof of vaccination or a recent negative COVID-19 test are now required at some large gatherings, including Raiders football games and the CES 2022 convention.

Gov. Steve Sisolak has declared large indoor conventions can go maskless if sponsors require all attendees to be vaccinated.

The state released an official definition of a COVID-19 death last year.

Most who died were age 60 or older with underlying health issues. In Clark County, a large majority had underlying health conditions, making them more susceptible to severe outcomes, according to data.
