(CNN) The city of St. Louis and St. Louis County reinstated an indoor mask mandate on Monday to try to stop the spread of Covid-19, even as Missouri's attorney general followed through on a threat to sue over the requirement. Beginning Monday, St. Louis required those ages 5 and older to wear masks in indoor public spaces and on public transportation. Attorney General Eric Schmitt filed a lawsuit against the mandate on the day it went into effect. The mandate, intended to cut down on further spread of the virus, applies to vaccinated and unvaccinated people. At a press conference, Mayor Tishaura Jones said the city is still at a "dangerous point" with the virus, facing infection numbers not seen since December.
