COVID-19 Current Wastewater Viral Activity Map

US Centers for Disease Control

This page shows CDC data on COVID-19 in wastewater with a five- to 12-day delay. For example, when the map is updated on April 14, it shows the data for the week ending April 9.

Scroll down to see a map showing the COVID-19 level in wastewater in each state.

Note: When a surge happens, virus levels in wastewater go up first - before case counts or hospitalizations.

FluView

US Centers for Disease Control

The map on this page is based on how many people see their health care providers because they have a fever plus a cough and/or a sore throat. That group of symptoms is called "influenza-like illness," or ILI.

The colors on the map tell you how much influenza-like illness has been reported in each state with a one- to two-week delay. For example, when the map is updated on April 14, it shows the data for April 1 - 7.

Note: The levels shown on the map are based on symptoms only, not on test results.
