Fig 1.
Distribution of the recommended distances for each country.
(A) The y-axis indicates the total number of countries for each recommended minimal distance for physical distancing. The 3- and 6-feet distances were converted into 1- and 2-m distances, respectively. There are only two countries which recommended 1–1.5 m (Guinea-Bissau and Taiwan), one 1, 1.5 and 2 m (South Africa) and one 1.5–2 m (Honduras). (B) Worldwide map of the recommended minimal distances for each country.

Boxplot & Generalized linear model of the effective reproduction number Rt (model using Arroyo-Marioli et al. data).
Boxplot of the estimated effective reproduction rate in May 8th, 2020 (A) and in Aug 1st, 2020 (B) plotted against the recommended distance during COVID-19 pandemic. Gaussian generalized linear model of the estimated effective reproduction rate in May 8th, 2020 (C) and in Aug 1st, 2020 (D) according to the recommended minimal distance.

Effect of recommended distance on the dynamics of COVID-19 pandemic.
The estimated standard error of the mean (SE), χ2 statistics, degree of freedom (df), and corresponding p-values are given. Bold characters indicate significant (P<0.05) effects.
Table 2.
Effects of different variables on the probability of having a recommended distance of one versus more than one meter for two different models.
The estimate (β), standard error of the mean (SE), χ2 statistics (degree of freedom (df)), and corresponding p-values are given. For each qualitative variable, the modality included as the intercept is indicated in parentheses in the first column. Bold characters indicate significant (P < 0.05) effects.
