Several people who attended a high school swim party in Arkansas have contracted Covid-19, Gov. Asa Hutchinson told reporters on Saturday.

Earlier this month, at least 180 people were exposed to the novel coronavirus in California when a person who tested positive for Covid-19 attended a religious service on Mother’s Day.

On Saturday, Hutchinson said Arkansas is seeing an increase of Covid-19 cases in what the governor calls a second peak.

Unlike other states, Arkansas has not been under a stay-at-home order to limit the spread of the novel coronavirus.

He pointed to his actions in declaring a public emergency when Arkansas had its first confirmed case of coronavirus, closing the state’s schools and increasing testing.
