National Influenza Activity and Surveillance

FluView, a weekly influenza surveillance report, and FluView Interactive, an online application which allows for more in-depth exploration of influenza surveillance data, are updated each week.

Utah Department of Health Seasonal Influenza

Influenza is a contagious infection of the nose, throat, and lungs. There are two main types: A and B. Each type includes different strains that change from year to year.

Utah Pandemic Influenza

An influenza pandemic can occur when a non-human (novel) influenza virus changes in such a way that it is able to infect humans easily and spread easily from person to person. Examples of recent novel viruses include avian influenza A (H5N1) and avian influenza H7N9. These are non-human viruses that circulate in birds in parts of the world so there is little to no immunity against these viruses among people.
