Data are updated weekly on Wednesdays. Most of the tables, charts, and maps in this report are interactive. Tables can be sorted by clicking on column headings. Maps and charts can be sorted, zoomed, selected, etc. using the mouse cursor. Data will appear when you hover or click the mouse cursor. Controls appear at the top right corner of charts when you put the mouse cursor on the chart. The data used to create the charts on this dashboard are also available for download. Case and laboratory data that can be queried are available on IBIS.

What’s new this week

Row

COVID-19

Row

COVID-19 activity is low in Utah, but is expected to increase as the winter months advance. The best time to get an updated COVID-19 vaccine is now to be better protected from COVID-19 infection.

Row

Influenza

Row

Flu activity is low in Utah. However, we expect flu activity to increase in Utah as the winter months advance. The best time to get a flu shot is now to be better protected throughout the flu season.

Row

Respiratory syncytial virus (RSV)

Row

RSV activity remains low. Ask your doctor about how to best prepare for the upcoming RSV season. You may be eligible for immunizations.

Row

Vaccination recommendations

Row

COVID-19

The updated COVID-19 vaccine is now available to help protect against serious illness and hospitalization. The protection gained through past vaccination or infection wanes over time, and this vaccine more closely targets the Omicron subvariants currently circulating in Utah and around the country.

Who should get it? CDC recommends everyone 6 months of age or older receive at least 1 dose of an updated COVID-19 vaccine-more than 1 dose is recommended for those who are immunocompromised or who have not been previously vaccinated. You can read more about that here.

When should I get it? You should get vaccinated as soon as possible to offer the best protection during winter months, when disease activity typically increases. If you have recently had COVID-19, you may consider delaying vaccination until 3 months after you have recovered.

Where can I get it? To find a COVID-19 vaccine, reach out to your health care provider, find a nearby provider here, or search your ZIP code at https://www.vaccines.gov/search/

Influenza

Flu vaccines help reduce the spread of flu and decrease the risk of severe illness due to flu.

Who should get it? Everyone older than 6 months of age should get a flu vaccine every year with rare exceptions. For people aged 65+, some vaccines are recommended over others. You can read more about that here, and your provider can help you find the best vaccine for you.

When should I get it? You should get a flu vaccine each year close to the beginning of the flu season (October). If you are not able to at this time, you can still get it in the coming months to receive protection.

Where can I get it? To find a flu vaccine, reach out to your health care provider or local health department, or search your ZIP code at https://www.vaccines.gov/search/

RSV

Respiratory syncytial virus (or RSV) is a respiratory virus that typically causes mild, cold-like symptoms. For certain groups, RSV infection can be more serious. Infants and older adults are more likely to experience worse symptoms and require hospitalization. Each year, an estimated 58,000 to 80,000 children younger than age 5 and 60,000 to 160,000 older adults are hospitalized due to RSV infection. Vaccines and monoclonal antibody treatments are available to provide additional protection against serious illness.

Who should get it? Adults 75 years of age and older should receive a single dose of RSV vaccine. Adults 60-74 years old at increased risk for severe RSV disease should also receive a single dose of RSV vaccine. You can read more about CDC’s recommendations here.

Infants younger than 8 months should receive 1 dose of nirsevimab, a monoclonal antibody treatment. Additionally, infants and children 8-19 months of age who are at increased risk for severe RSV disease should receive 1 dose of the antibody treatment. Children younger than 24 months of age with certain conditions that make them more susceptible to severe RSV disease may be eligible for palivizumab, a different antibody treatment. You can read the American Academy of Pediatricians’ recommendations here.

People who will be 32 to 36 weeks pregnant between September and January should get 1 dose of maternal RSV vaccine to protect their babies.

When should I get it? If you are in one of the groups above, you should get the RSV vaccine or antibody treatment as early in the season as possible.

Where can I get it? To find a RSV vaccine or antibody treatment, reach out to your healthcare provider or a pharmacist near you.

Syndromic surveillance: COVID-19, influenza, and RSV

The graphs below show data reported by Emergency Departments (EDs) which submit syndromic surveillance data to the National Syndromic Surveillance Program (NSSP) at the CDC. Currently, 49 of Utah’s EDs submit data. These data reflect the 7-day average of both the total number of visits and the percentage of visits that match CDC’s national syndromic definitions for COVID-19, Influenza, and RSV. These definitions only consider the diagnosis discharge codes for each condition, since January 1, 2019. These data are reported before someone is tested and are intended to provide indications of trends occurring throughout Utah. The numbers and percentages presented are based on the patient’s address of residence when visiting an ED. For example, if a Davis County resident visits a Salt Lake County ED, the count will be associated with the Davis County numbers.

Mortality surveillance: pneumonia, influenza, and COVID-19 (PIC)

Row

Each week, we collect the total number of death certificates received and the number of certificates for which pneumonia, influenza (flu), or COVID-19 was listed as an immediate, underlying, or contributing cause of death. The percentage of deaths due to pneumonia, influenza, and COVID-19 are compared with a seasonal baseline and predicted epidemic threshold, which are based on data from past flu seasons. These data are used to monitor the severity of pneumonia, influenza, and COVID-19 illness in the community.

Data background

Mortality percentage: The percentage of mortality attributed to COVID-19 includes only death certificates that list COVID-19 as a cause of death but not influenza. The percentage of mortality attributed to P&I includes only death certificates that list pneumonia and/or influenza as a cause of death but not COVID-19. Thus, death certificates that list both influenza and COVID-19 as causes of death are only included in the percentage of mortality attributed to pneumonia, influenza, and COVID-19 (PIC). There may be a lag in mortality reporting due to the time it takes to investigate and complete death certificates.

The methodology used for this report was adapted from the CDC FluView model for Mortality Surveillance.
