The Chester County Health Department receives all test results for mpox. For all positive test results, the Health Department will conduct an investigation and contact tracing. Any individual suspected of being a close contact of someone who tested positive for mpox will be contacted directly by the Chester County Health Department and given post-exposure recommendations. Individuals who have been told they are a close contact of a someone who does not live in Chester County but has tested positive for mpox should contact the Chester County Health Department to discuss post-exposure recommendations at 610-344-6225.
In cases of discordant and inconclusive results, the Pennsylvania Department of Health and CDC recommend retesting the patient. Until new test results are processed, the patient should continue to isolate.
