Covid-19 which is now spread in clusters cannot become widespread, as long as there are working health authorities. We will not allow the coronavirus infection curve to go up, the Director of the National Center for Infectious and Parasitic Disease and member of the National Coronavirus Headquarters Professor Todor Kantardzhiev said. The increased number of the Covid-19 cases registered last week is due to the celebration of religious feasts, Professor Todor Kantardzhiev contends. Due to non-compliance with the measures, the Covid-19 transmission index rose from 0.8% last week to 1.2% at present.
