District Health Department #10 announced Monday that the Delta (B.1.617.2) variant of COVID-19 was recently identified in Crawford County in an individual with a history of international travel.
The Delta variant was first identified in India and resulted from mutations to the SARS-CoV-2 virus, the virus that causes COVID-19. According to CDC, early findings show that the Delta variant may be associated with an increased risk of death, but more research needs to be done. Research also shows that the Delta variant may be significantly more transmissible than other variants. At this time, there is some evidence that vaccines remain effective against the Delta variant.
The first Michigan case of the Delta variant was identified in Ottawa County in June. Several other cases have been identified in Michigan since the first case was announced. Only a small percentage of COVID-19 tests are sequenced to identify the variant strain. In addition, it takes additional time to perform the genetic sequencing. Therefore, it is likely that there are additional unidentified cases of the Delta variant in the DHD#10 ten-county jurisdiction at this time.
DHD#10 continues to distribute the COVID-19 vaccine to eligible individuals. To schedule a COVID-19 vaccination appointment, go to .
