Switzerland is warning people not to storm pharmacies next Wednesday when free Covid-19 self-tests become available, saying a rush of pandemic-weary test seekers would overwhelm the system.

Swiss residents will be able to get five free home test kits monthly, saving them from having to go to a doctor for the procedure, according to Reuters. But Martine Ruggli, head of the pharmacy industry group PharmaSuisse, warned people not to come all at once.

“It's very important that not everybody storms into the pharmacies on the first day because then we couldn't manage the crush,” Ruggli told a news conference.
