In the state’s conservative northern reaches, health officials have battled against widespread distrust of the vaccines, skepticism about the virus and anger over mask mandates and lockdowns. The region’s dramatic spike in cases attributed to the highly contagious Delta variant mirrors what is happening across the country in states that supported President Trump, who acknowledged that he deliberately downplayed the danger of the coronavirus early last year. “We have spent too much time fighting each other and not fighting the virus,” McGuire said. “Unfortunately, politics has ruled the day. We need the public’s health to come first.” Perhaps nowhere in California is the disaster more acute than in Del Norte County in the remote northwest corner, where the redwood forest meets the sea. Cumulative coronavirus cases have more than doubled over the last three months, from 1,380 confirmed on May 10 to 2,805 on Friday. At least 70 cases were confirmed Thursday alone.
