Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020

We show the distribution of SARS-CoV-2 genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three available genomic nomenclature systems for SARS-CoV-2 to all sequence data from the WHO European Region available during the COVID-19 pandemic until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation. We provide a comparison of the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2.Peer reviewe

Burn-out Syndrome and Teacher Job Satisfaction

The concept of burnout is often used when trying to explain the state of chronic stress in people working in a field that involves contact with people, such as, in our case, education. Teachers spend a long time at work and are involved in multiple relationships: both with students, colleagues (other teachers, principals), and with other parents. All these various interactions require a mental and even physical effort. Also, teaching and assessment activities consume energy and require considerable effort. Thus, the resources needed by the teacher (time, financial), work and performance requirements can erode the teacher's energy and enthusiasm, which sometimes leads to the manifestation of burnout symptoms. Burnout is “a state of chronic fatigue, depression and frustration generated by the devotion of a cause, a way of life or a relationship that fails to produce the expected rewards and ultimately leads to diminished involvement and work” (Zlate, 2007 , pp. 598 in Richelson, 1980. &nbsp
