Story summary

Wastewater testing can detect measles infections days to months before clinical confirmation, according to Centers for Disease Control and Prevention (CDC) studies.
In Colorado, wastewater testing identified measles a week before two cases were confirmed.
Oregon researchers found positive wastewater samples ten weeks before a 30-case outbreak.
The proposed budget would cut funding for the national wastewater surveillance system from $125 million to $25 million, risking reduced outbreak management.
