Covid-19 trajectories: Monitoring pandemic in the worldwide context	2020-06-05		.txt	text/plain	7923	425	50	Different models, mostly assuming a series of diseases states such as the 'Susceptible-Infected-Removed' (SIR) types (see below) have been used to describe 'epi-curves' of selected countries and regions under consideration of i) spatial heterogeneous outbreak and transmission scenarios, and ii) the effect of NPIs [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] . The obtained trajectories then enable to visually estimate the dynamic state of epidemic in terms of simple shape characteristics such as slope, parallel shifts or turning points with direct relations to transmission and removal rates of the disease. They enable monitoring the state in terms of differences and similarities between the countries and geographic regions revealing specifics and commons of epidemic spread: (i) A unique linear slope of most of the trajectories in the intermediate abscissa range is indicative for exponential growth in early phases of the outbreak of the pandemic (low level of immunity in the population).	./cache/cord-252244-y5w9hjy8.txt	./txt/cord-252244-y5w9hjy8.txt
