Rhythmic components of COVID-19 daily cases in various countries	2020-07-24		.txt	text/plain	2319	141	58	The scope of this study consisted in assessment of COVID-19 daily case increment dynamics in various countries in order to identify rhythmic components. . https://doi.org/10.1101/2020.07.23.20161240 doi: medRxiv preprint Figure 1 shows the global dynamics of COVID-19 daily case increment and the results of the time series analysis using three approaches: periodogram ( fig. Since the beginning of the review interval falls on 1 March (Sunday) and the source data reflect incidence increment reported for the previous 24 hours, the first two points on the X-line correspond to weekend days in figure 3 distribution As follows from figure 2, phasal dips and peaks occur on different days of the weekly period depending on the country. . https://doi.org/10.1101/2020.07.23.20161240 doi: medRxiv preprint As follows from figure 3, the pandemic spread phases almost coincide in these two countries. 4. In the incidence dynamics of some countries consistent and statistically significant periods other than weekly have been recorded, i.e. 6, 8 or 10 days.	./cache/cord-326861-qooax2xc.txt	./txt/cord-326861-qooax2xc.txt
