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 (reproduktsiooni alusarv)

Definition from Matemaatika ja statistika instituut:
Reproduktsiooni alusarv, R0, on ühe nakkusliku isendi poolt keskmiselt nakatatud teiste isendite arv täiesti vastuvõtlikus populatsioonis (kogu selle aja jooksul, mil isend on nakkuslik).

Example sentence(s):

Eksperdid on viimastel päevadel välja arvutanud iga puhangu jaoks tähtsa arvu: reproduktsiooni alusarvu R0. See näitab, mitu inimest on üks inimene keskmiselt nakatanud. - Postimees
R0 täpse väärtuse põhjal ei saa teha samas üheseid järeldusi. Näiteks võivad hinnangut kiiva ajada haiguse ülilevitajad. - ERR
Tema sõnul on hooajalise gripi R0 1,3, samas kui 2002.–2003. aastal peamiselt Mandri-Hiinas 8000 inimest nakatanud ja 774 tapnud SARS-i R0 oli 2–5. Leetrite R0 on 12–18. - Võrumaa Teataja
