Information released by Prosser Memorial Health (PMH) Emergency Department on Tuesday, August 3 indicates some doctors believe Delta is the culprit (the new COVID Strain) for increasing case counts, and they are beginning to see what are called "breakthrough" cases. Dr. Robert Wegner is the Emergency Medical Department Director at PMH, and he says 80 percent of the COVID strains in the U.S. are the new Delta variant. He said in the last two weeks, PMH has seen a dramatic increase in "COVID positive patients." Dr. Wegner reported: "We are not directly testing our positive cases for Delta Variant but based on how the behavior of COVID has changed, I suspect that the Delta Variant is prevalent in our community."
