English term or phrase: R0 (reproductive rate)
Definition from Kaiser Family Foundation:
An epidemiologic metric used to describe the contagiousness or transmissibility of infectious agents, which is usually estimated with complex mathematical models developed using various sets of assumptions. It is an estimate of the average number of new cases of a disease that each case generates, at a given point in time. R0 estimates for the virus that causes COVID-19 are around 2 to 3, which is slightly higher than that for seasonal influenza (R0 ~1.2-1.3), but far lower than more contagious diseases such as measles (R0 ~12 - 18).

Example sentence(s):
  • The R0 is not an intrinsic feature of the virus. It can be lowered through containment, mitigation and ultimately “herd immunity,” as people who have recovered become less susceptible to infections or serious illnesses. For the epidemic to begin to end, the reproduction rate has to drop below 1. The Washington Post
  • This chart shows two curves with two very different virus reproduction rates. In the steepest curve, the virus reproduces quickly in a short period of time. In this scenario, emergency rooms, intensive care units and other parts of the health care system are overwhelmed. In an overwhelmed system, mortality rates can be high and those infected may not get the treatment they need. World Economic Forum
  • When the team modeled a scenario in which contacts were notified the instant a person tested positive, it was possible to push the reproductive rate of the virus below that threshold, the team reported in a preprint this week. Science

R0 (taux de reproduction de base)

Definition from AEEMA:
Nombre moyen de cas (ou de foyers) secondaires provoqués par un sujet (ou un élevage) atteint d’une maladie transmissible au sein d’une population entièrement réceptive.

Example sentence(s):
  • Le R0 est un nombre qui décrit l’une des caractéristiques d’une épidémie. C’est une mesure relativement intuitive qui permet de dire combien de personnes en moyenne seront infectées par une personne contaminée. Par exemple, si R0 = 3 au 1er cycle d’infection, cela signifie qu’une première personne infectée va transmettre le virus à trois autres personnes. Au 2e cycle d’infection, ce seront neuf personnes qui seront touchées. Au 12e cycle, nous aurons environ un demi-million de personnes atteintes. Si le R0 est moitié moins élevé, soit 1,5 au lieu de 3,0, au 12e cycle d’infection nous aurons environ 150 personnes qui seront infectées au lieu d’un demi-million. On voit toute l’importance du R0. - Udem Nouvelles  
  • Le taux de reproduction de base R0 Le taux de reproduction de base R0 constitue le nombre de cas secondaires produits par un individu infectieux moyen au cours de sa période d’infectiosité dans une population entièrement constituée de personnes sensibles (non immunisées). Le R0 est un seuil. - Quoi dans mon assiette  
  • Le taux de reproduction est le nombre moyen de cas secondaires générés par une personne durant la période où elle est infectieuse, symptomatique ou non. Lors de l’introduction d’une infection dans une population entièrement susceptible, on parle de taux de reproduction de base (Ro). - Institut de Veille Sanitaire
