This is the rate of increase graph for Covid-19 cases for Dallas County. As you can see, the rate of increase has plateaued in the last 4 days at around 250 new cases a day.
I expect this rate to jump at the end of this week or the beginning of next week as the effect of the loosening of lockdown and stay-at-home works its way through into infection rates. The only way that we will not have a steep increase will be if a significant percentage of the population is already infected with Covid-19. This is possible, but since testing is confined to people suspected of having the virus, and no generalized testing of the population is being conducted, no information exists to determine the current general level of infection.
