Rise in COVID cases week over week: 24 percent Multiple states’ spikes are being tied to an annual motorcycle rally in Sturgis, South Dakota, which ran from Aug. 7 to Aug. 16 and drew in a crowd of over 100,000 people. The gathering made national headlines when attendees flouted social distancing guidelines, including a performance by popular ’90s band Smash Mouth to a mostly mask-less crowd. Since the rally ended, multiple people who were in attendance have tested positive for COVID and cases are believed to have spread to other states, including Wyoming. It was one of two nearby states that also saw cases climb last week. The least populous state in the nation had nearly 300 new COVID cases—for reference, Wyoming has had 3,600 total cases since the start of the pandemic.

While it’s the only state on this list whose spike is not tied to the Sturgis Motorcycle Rally, it also saw a considerable jump in newly reported cases, largely because of a single event. Local health officials cited an Aug. 7 wedding celebration as the source of at least 53 new infections, which have so far resulted in one death. More than half of the people who attended the 65-person event—which was in violation of the state’s 50-person limit on gatherings—tested positive for coronavirus.

The city of Sturgis is now conducting mass COVID testing for its roughly 7,000 residents, according to the Associated Press. And the situation is expected to worsen. State epidemiologist Joshua Clayton told The Rapid City Journal that cases will likely continue to appear until Aug. 30, which would be two weeks from the rally’s end date. “That would be when an individual could develop symptoms,” Clayton said. “If there’s a couple of days of delay in a person seeking care or getting those test results back, it may push into September. We’re not out of the woods yet in terms of potential public notices resulting from the Sturgis rally.” And for more signs you could have COVID, check out These Are the 51 Most Common COVID Symptoms You Could Have.
