Covid-19 has taken hold across the country. But not all upticks are the same.

NBC News is tracking which states are seeing prolonged or dramatic case increases as the country heads into summer.

The charts below show each state’s two-week average of new Covid-19 cases. Areas highlighted in red represent periods where the rate of new cases exceeds the two-week average. The longer the red line, the longer cases have been increasing and the more rapidly the virus is spreading.

The charts will update daily before 11 a.m. Eastern.
