PHOENIX (AP) — Health officials in Arizona on Monday reported 608 more confirmed COVID-19 cases and no additional deaths for the second consecutive day. The new figures bring the state's pandemic totals to 844,910 cases and 16,990 deaths.

The number of patients hospitalized for confirmed or suspected COVID-19 cases fell to 516 on Sunday — the lowest level since September. In addition, the number of ICU beds used by COVID-19 patients dipped to 148.

The state’s coronavirus figures also showed the number of vaccine doses administered stood at more than 3.7 million, with over 2.3 million people, or roughly 33% of the state population, having received at least one dose and over 1.4 million people being fully vaccinated.

Arizona has started transitioning its state-run vaccination sites to inddor operations or to night-time hours until the move indoors can be made. Dr. Cara Christ, director of the state Department of Health Services, marked the opening Monday of a site at the Dexcom medical equipment distribution center in Mesa. This site replaces an outdoor facility at Chandler Gilbert Community College.

Christ announced the state will launch a new mass vaccination site in Scottsdale at WestWorld later this month. The vast exhibition center will initially offer as many as 4,000 appointments daily between 7 a.m. and 5 p.m. starting April 22. It will have the capacity to eventually serve up to 10,000 people a day, officials said. Health insurer Cigna will provide day-to-day clinical staffing.

The number of infections is thought to be far higher than reported because many people have not been tested, and studies suggest people can be infected with the virus without feeling sick.
