We expect that around 4 counties will report at least one human case this week, down from 6 cases last week. The 2018 WNV season in SD is winding down. Not only is the temperature expected to decline, which will suppress mosquitoes and the virus in them, but we've actually had colder weather than usual for this point in the year, which may lower risk even faster than usual. Risk is still real, however, and school begins this week, possibly bringing students outdoors in evening events.
