Waldo County finds itself back in a position it hasn’t been in since April as it contends with a COVID-19 outbreak of at least 42 cases linked to a church in Brooks.Until last week, the county of fewer than 40,000 residents hadn’t seen a major outbreak since early in the pandemic, when the coronavirus swept through The Commons at Tall Pines nursing home, infecting 43 residents and employees and killing 13 residents there. On Tuesday, Waldo County had 49 known active cases of the virus, according to the Maine Center for Disease Control and Prevention.
