15/21. Canada will experience a surge in its #COVID19 epidemic activity at medium levels, with increasing although low levels of mortality, for 7 more days.

1/8 - “There is overwhelming evidence that inhalation of severe acute respiratory syndrome coronavirus 2 (#SARSCoV2) represents a major transmission route for coronavirus disease 2019 (#COVID19) science.sciencemag.org/content/370/65…
2/8 - “We must clarify the terminology to distinguish between aerosols and droplets using a size threshold of 100 µm, not the historical 5 µm. This size more effectively separates their aerodynamic behavior, ability to be inhaled, and efficacy of interventions.”
3/8 - “Viruses in droplets (larger than 100 µm) typically fall to the ground in seconds within 2 m of the source and can be sprayed like tiny cannonballs onto nearby individuals. Because of their limited travel range, physical distancing reduces exposure to these droplets.”
1/6. The USA, Oct. 17 to 23 - Will be experiencing a rise in its #COVID19 epidemic activity at high levels, with high-medium mortality for 7 more days.
New risk map and 5 states detailed.

2/6. New York will be plateauing in its #COVID19 epidemic activity at medium levels, with low levels of mortality, for 7 more days. A situation apparently better controlled than currently in Western Europe.
3/6. Texas will be plateauing at high level of its #COVID19 epidemic activity, with decreasing although still high levels of mortality, for 7 more days.
1/5 - Un changement de stratégie de recherche des contacts s’impose en urgence. À Genève on ne trace les contacts jusqu’à maximum 48h avant les premiers symptômes (“forward tracing”recherche prospective des contacts). Mais ce n’est pas assez performant de faire ainsi...
2/5 - ...Il faut plutôt rechercher en priorité dans les 12-14 derniers jours quels ont pu être le ou les contact(s) contaminant(s) et s’arrêter d’abord sur celui (ou ceux) qui aurai(en)t pu être à l’origine d’une super-propagation (megaclusters). Et se focaliser sur ceux-là...
3/5 - Exercice pratique : Mme X, 30 ans, détectée positive. Elle vit seule, prend le bus 2 jours/sem pdt environ 25 min pour aller au travail, précautionneuse, masquée.
Les questions à poser : avez vous été à la cafétéria, restaurant, bar, théâtre,cinéma,culte,club de sport,...?

1/8 - Il y a deux modalités de traçage des contacts:
a) Traçage prospectif, classique, on recherche les contacts du cas;
b) Traçage rétrospectif,”à la japonaise”,on recherche qui a contaminé le cas.
La priorité des priorités c’est de privilégier b) et ne faire a) que si on peut.
2/8 - Le fondement théorique vient du paramètre k de dispersion, élevé pour la grippe (de dynamique homogène) et faible pour le #SARSCoV2 dont la dynamique est hétérogène, émerge en clusters et en événements super-propagateurs: 10 à 20% des contaminations drive toute la pandémie.
3/8 - Si 80-90% des cas contaminent 0 ou 1 cas, on n’a pas à se fatiguer à tracer leurs contacts. Ils ne nous inquiètent pas. En revanche, il faut tout mettre en œuvre pour stopper la propagation causée par les 10 ou 20% restants, à commencer par les identifier. Comment faire ?
