Public health officials say they’ve identified a total of eight measles cases in Shasta County as contact tracing continues.

The cases are linked to one first identified Jan. 30, with Shasta County Health and Human Services officials saying all seven new cases involve close contacts of that person.

Officials noted that the new patients all isolated before they became possibly contagious.

“Our public health teams want to thank the individuals affected, those who were exposed, and our community as a whole for working closely with our staff and following public health guidance. Your quick action and support have helped us manage this outbreak and continue protecting our community,” said Shasta County Public Health Director Katie Cassidy in a statement.
