3. Almost Closed Cases

3.1. Spain

Figure 5. Covid-19 case curves and rms for the data from Spain.

The case data from Spain seems to have three harmonics (or waves). The last wave $Z_{c}$ (blue line) seems to be reaching its flattening. The root mean square (rms) deviations in the inlet were calculated by the fitted curve \(Z_{71}\) using the whole case data.
