Before finishing my "oceanographic" thread on pandemic waves 😂, a weekend post on the multifractal analysis of SARS-COV-2 🤗
2) Multifractal analysis is a mathematical approach used to study complex systems that exhibit self-similarity at multiple scales. In multifractal analysis, the focus is on characterizing the distribution of different scaling exponents across the system.
3) When we study a virus, these analyzes allow:
- to shed light on the evolutionary dynamics of viruses. This can help understand the mechanisms behind viral evolution, including the emergence of new strains and the development of drug resistance.
At the start of the pandemic, it was simple. We had a VoC which was generating a wave of cases and hospitalizations.

2) After the first Omicron, things started to become more complicated with, within a wave, 2-3 variants
3) At the end of 2022 and beginning of 2023, we had more and more variants within a wave.
