ACROSS AMERICA — The Centers for Disease Control and Prevention is now warning against wearing one form of mask, suggesting that wearing ones with exhalation valves or vents would actually speed up the spread the coronavirus rather than prevent it.

"Masks with exhalation valves or vents should NOT be worn to help prevent the person wearing the mask from spreading COVID-19 to others (source control)," the CDC has added to its guidance on masks.

The organization continues to urge wearing other forms of masks when in public, however. The CBD "recommends that people wear masks in public settings and when around people who don’t live in your household, especially when other social distancing measures are difficult to maintain."

Kentucky on Wednesday reported 1,163 new cases. Florida reported 276 new deaths Tuesday, and Georgia reported 125 the same day.

Florida is second when it comes to highest positivity rates with 17.17 percent, falling behind only Texas at 24.23 percent, according to Johns Hopkins University data. Maine and Connecticut have the lowest positivity rates, at 0.45 percent and 0.77 percent, respectively.

In all, 38 states remain above the positive testing rate recommended by the World Health Organization to safely reopen. To safely reopen, WHO recommends states remain at 5 percent or lower for at least 14 days.

The virus continues to take its toll on sports. Three major collegiate conferences have now postponed their fall sports seasons. The Big East decision to put off all fall sports until possibly the spring on Wednesday came a day after the Big Ten and Pac-12 opted to do the same.
