Pour un ultime de 3500, le pic semble avoir été atteint le 23 mars avec 336 (non prévu) et il pourrait avoir déclin, mais HL est peu fiable

-Décès France

La fourchette des ultimes continue à varier avec 1600-3000 contre 1000-2300 hier

Un ultime à 1600 donne un pic le 23 mars et un ultime à 3000 donne un pic le 27 mars : soit seulement 4 jours d’écart en presque doublant

Grand Est Augmentation brutale (non prévu) et HL (12 jours) tend vers 400 décès avec 500 pour les 8 derniers jours contre 300-350 hier

Il est difficile de prévoir mais l’augmentation du 23 mars pourrait être anomalique ou non ?

Pas de données nouvelles pour Hauts de France, Auvergne et Bretagne

Italie Le nombre de décès a diminué depuis 2 jours et HL tend vers 14 000 (8 000-24 000 hier)

Conclusion La prévision des cas confirmés est difficile, mais on peut se consoler en sachant que de nombreux cas ne sont pas déceler car sans symptômes. La prévision des réanimations est intéressante car bien inférieure au potentiel des lits, alors que certains semblent craindre le pire. On peut espérer un pic des décès pour la France avant la fin du mois de Mars, ainsi que pour l’Italie et l’Espagne. Il faut être réaliste car nos prévisions passées ont souvent été démenties sur le nombre mais pas sur la date du pic. Nous savons que nous pouvons nous tromper en étant trop optimistes, mais beaucoup moins que les nombreux pessimistes qui prévoit un pic en Mai.
