Detection of Mpox Virus in Pierce County Wastewater

PIERCE COUNTY, Wash. — The Washington State Department of Health, along with the University of Washington, has identified clade I mpox, commonly known as monkeypox, in wastewater samples from Pierce County.

This finding, reported on September 24, has led the Tacoma-Pierce County Health Department to team up with the Centers for Disease Control and Prevention (CDC) and the state health department to enhance wastewater testing efforts.

As of now, there have been no reported cases of clade I mpox in Pierce County. The CDC notes that six cases of this variant have been confirmed in the United States, all linked to recent travel to areas experiencing outbreaks.

Notably, there has been no ongoing transmission of clade I mpox within the U.S.

Dr. James Miller, Health Officer for Tacoma-Pierce County, highlighted the necessity of public health monitoring. He remarked, “This is a rare occurrence, and it illustrates how public health stays alert to track disease spread and keep the community informed when necessary.”

Dr. Miller reassured everyone that the risk remains low, advising anyone with symptoms to reach out to their healthcare providers.

Healthcare professionals are urged to consider mpox in patients showing rashes that resemble the virus and to take their travel history into account. All suspected cases must be reported to the Health Department.

Alongside traditional clinical reporting, wastewater testing is being utilized to detect clade I mpox early.

The mpox virus spreads through close physical interactions, including both sexual contact and household settings. Prevention methods for clade I and clade II are largely the same. Symptoms range from rashes, which may appear as bumps or blisters, to flu-like signs that often come before the rash.

Most individuals tend to recover within two to four weeks; however, it can pose serious risks for children, pregnant people, or those with weakened immune systems.

Residents experiencing new rashes or related symptoms should avoid skin-to-skin contact and seek medical guidance. A vaccine is available for higher-risk individuals, and it’s advisable for them to consult their healthcare providers or check the health department’s website for further vaccination details.
