(CNN) Los Angeles County -- the most populous county in the US -- is seeing "exponential growth" of Covid-19 cases as Delta takes over as the dominant strain, according to local health officials. "We do continue to see an uptick in cases and hospitalizations," Los Angeles County Public Health Director Barbara Ferrer said Thursday. And the difference in vaccination rates between Republicans and Democrats has grown over the last two months, a report released Thursday from the Kaiser Family Foundation shows. By July 2021, the average vaccination rate in Trump-leaning counties was 35%, and 46.7% in Biden-leaning counties. "A key component of any effort to boost vaccination rates among Republicans will be identifying the right messengers," the researchers wrote.
