North Carolina health authorities have issued an alert after detecting mpox virus particles in the state's wastewater system. The North Carolina Department of Health and Human Services (NCDHHS) reported that mpox, primarily spread through prolonged skin-to-skin contact, was found in sewage samples. This suggests the possibility of undiagnosed or unreported cases of clade I mpox, a type not previously documented in the state.
So far this year, two mpox cases have been recorded in North Carolina, but the North Carolina Department of Health and Human Services is focusing on the newly detected clade I type. This type has been reported in only four cases across the United States. Wastewater testing conducted in Greenville, NC, on March 25, March 28, and April 8, revealed potential undiagnosed infections in the area. The detection indicates the virus may be present in the state, even though no confirmed cases have been reported.
Mpox symptoms can include a rash that starts as pimples or blisters, followed by scabs, and may be accompanied by flu-like symptoms. North Carolina Department of Health and Human Services encourages healthcare providers to consider mpox in patients with compatible symptoms and to inquire about recent international travel. Providers should report any suspected cases to the local health department. The public is also urged to get vaccinated for protection against both clade types of the virus.
The North Carolina Department of Health and Human Services, along with the University of North Carolina at Chapel Hill and local health departments, has been using wastewater testing to track viruses in communities. However, proposed federal funding cuts may impact this surveillance program. The results are regularly updated on the NCDHHS wastewater monitoring dashboard.
Individuals who suspect they may have mpox or have been in close contact with someone diagnosed with the virus should visit a healthcare provider or contact their local health department. Vaccination is recommended for both prevention and to reduce the severity of illness.
