State health officials report that while a key marker of COVID-19 infection rates has fallen to new lows in the Las Vegas area, the number of deaths and new cases reported statewide are up. A 14-day positivity rate that tracks the percentage of people who are found to be infected dropped in Clark County to 4%. Statewide, the figure remained at 4.2%. Both are below a World Health Organization goal of 5%. But Nevada tallied 268 new cases on Wednesday and 10 more deaths. Those numbers are up from recent 14-day averages of 200 new cases a day and three deaths.
