After two consecutive todays of reporting over 2,000 new COVID-19 cases, Arizona health officials reported 1,846 cases Monday.
The state also reported only one new virus-related death.
The latest figures bring the pandemic death toll to 18,252 and the number of cases to 931,387.
The number of hospitalizations from the virus are also continuing on an alarming upward trajectory.
As of Sunday, 1,169 people were hospitalized statewide.
It hasn’t been that high since early March.
The Centers for Disease Control classifies every county in Arizona as having either substantial or high transmission of COVID-19.
While spread of the virus had been deemed moderate in Cochise County under the agency's measurements, the county had substantial transmission as of Monday.
Public health officials in the state and elsewhere attribute the worsening spread to the very contagious delta variant and low vaccination rates.
About 47% of Arizona's population and about 43% of Pima County's population is fully vaccinated.
Nationwide, nearly 50% of the population is fully vaccinated, according to the CDC.
