COVID-19, flu and RSV cases are rising in Maricopa County, and the numbers are higher than usual for this time of year, health officials said Friday.

“Respiratory viruses can cause severe disease, especially in infants, young children and older adults,” said Dr. Nick Staab, medical epidemiologist at the Maricopa County Department of Public Health.

“It is concerning to see so many cases before many holiday gatherings and travel have even happened. We are already seeing a strain on our healthcare systems.”

MCDPH is encouraging everyone ages 6 months and older to get vaccinated against COVID and flu to prevent additional cases as people gather this holiday season.

Influenza cases are now “widespread” in Maricopa County, which is the highest category of flu spread, according to a release.

The Centers for Disease Control reported Maricopa County is in the high category for COVID transmission. At this level of transmission, the CDC recommends wearing a mask indoors in public, which includes during travel and in other public settings.

Respiratory syncytial virus cases are more than two times higher than during the average peak, the county release stated.

There is no vaccine for RSV, but flu and COVID-19 vaccines are effective at preventing “many infections and reducing the severity of breakthrough infections,” county officials said.

People with symptoms should stay home and away from others unless they’re seeking healthcare, according to the release.

Symptoms of COVID-19, flu, and RSV can include:

• Runny or stuffy nose
• Coughing/sore throat
• Fever
• Muscle or body aches
• Fatigue
• Headaches

In children under age 1, symptoms of RSV can also include irritability, decreased appetite, decreased activity, and pauses while breathing (apnea).

“Staying up-to-date on flu and COVID-19 vaccines is a simple way to prevent infections, reduce the spread of respiratory illness and prevent severe disease,” Staab said.

“You can get them on the same day at many places, and there’s still time to get vaccinated before the holidays.”

It’s best to get vaccinated at least two weeks ahead of gatherings or travel so the body has time to build up protection, he said.
