When the COVID- 19 pandemic occurred, all the main communication systems of medical research have undergone an epochal change. Many online journals and magazines have tried to publish inherent works of this specific problem as soon as possible, soliciting and preferring them to others, thus changing the system of free acceptance of scientific works once. Moreover, the way to communicate these works  has no longer occurred through standard Scientific Congresses but with other systems, websites/streaming and webinars or virtual conferences.   Now there is something systematic missing, which foresees that this may last in the future, in the post COVID-19 era (AC): the communication system of the medical sciences will be different from now on. There will be far fewer classical-style conferences like the ones so popular before COVID-19 outbreak (BC)  but there will be more webinars, in streaming  and virtual conferences.
