A day after

, the state of Nebraska has imposed its first Directed Health Measure to combat the spread of COVID-19, imposing those same limitations on three additional counties.

Announced in a news release from Gov. Pete Ricketts on Thursday, the restrictions apply to Douglas, Cass, Sarpy, and Washington counties.

According to the measure, gatherings of more than 10 patrons, customers, or invitees — not including staff — are prohibited in schools, daycares, gyms, salons, fitness centers, auditoriums, stadiums, arenas, conference rooms, meeting halls, theaters, libraries, or other confined indoor or outdoor spaces. The restriction also applies to weddings, funerals, parades, fairs, festivals, concerts, and other indoor or outdoor events, the release states.

The measure remains in effect until April 30, according to the release.

Restaurants and bars in these areas are required to close their dining areas immediately, according to the release. Such establishments are allowed to continue takeout service, delivery, and curbside service until further notice.

The area applies to those counties in Educational Service Units No. 3 and No. 19, but school staff working in school buildings are exempt from the restriction, the release states.

According to the release, the restrictions do not apply to airports, bus and train stations, health care facilities, shopping malls, and other spaces where people are "in transit." They also do not apply to offices, factories, or retail and grocery stores, courts and other government offices, and polling places on an election day.
