A novel fractal structure for the cosmological horizon, inspired by COVID-19 geometry, which results in a modified area entropy, is applied to cosmology in order to serve dark energy. The constraints based on a complete set of observational data are derived. There is a strong Bayesian evidence in favor of such a dark energy in comparison to a standard $\mathrm{\ensuremath{\Lambda}}\mathrm{CDM}$ model and that this energy cannot be reduced to a cosmological constant. Besides, there is a shift…
