Guillaume Rozier, founder of this site allowing the monitoring of pandemic figures, believes that a upheaval in screening methods no longer makes it possible to obtain reliable data on the variant.
“ Broken thermometer ”
However, to refine this monitoring, Santé Publique France explained that since December 20, 2021, the screening integrates the monitoring of mutations which are specific to the Omicron variant, “ such as the deletion 69/70 and the substitutions K417N, S371L-S373P and Q493R ”. A new code, D, must therefore be added to the three previous ones to allow medical biology laboratories to include in screening results the presence of mutations specific to Omicron. This measure had the effect of causing a drop in the screening results. Certain laboratories have in fact continued to transmit their results according to the old system – A, B, C – while others are now based on the new operation, which includes the code D. Public Health France for its part still publishes the results. data under the old system. The imbroglio is such that now, “ the thermometer is broken “, and this at the worst time since the Omicron variant continues to spread at full speed, deplores Guillaume Rozier. Read also
