The World Health Organization says it could still take some time to get a full picture of the threat posed by omicron, a new variant of the coronavirus, as scientists worldwide scramble to assess its multiple mutations. Fond du Lac County Public Health Officer Kim Mueller says she’s confident scientists will learn more in the weeks ahead. Mueller says at this point there are a lot of unknowns. Mueller says the concern is how effective the current vaccine will be against the latest variant. Health officials say there are no cases of the variant identified in the U.S. But the nation’s top infectious disease expert, Dr. Anthony Fauci, says it was inevitable that it would make its way into the country.
