Hamilton County Adds COVID Restrictions After Rise to Red on Indiana Metrics Map NOBLESVILLE, Ind. (WISH) — Hamilton County turned red for the first time on the state’s coronavirus metrics map Wednesday. Red is the highest level of alert on the map. Some are calling it a wake-up call, and more COVID-19 restrictions will now be in place. Schools are faced with a challenge of what to do next. Christian Walker with the Hamilton County Health Department said travel during the holidays may be responsible for the high community spread of COVID-19 in Hamilton County. “Probably a lot of families who haven’t seen each other either since last Christmas or it’s been a while.”
