**5. Conclusions**

In conclusion, COVID-19 infection is, particularly in the seniors' population, a dangerous and life-threatening disease, which leads to a significant change of behavior. Since the elderly population usually suffers from many medical conditions requiring a continuous treatment process, it is essential to provide proper medical care also during the pandemic. We believe that the development of modern telemedical solutions would improve treatment outcomes, reduce comorbidities-related complications and unnecessary hospitalizations. Moreover, considering that physical and social activity is essential to maintain good physical and psychical health in an older population, we think finding a balance between caution and activity is crucial, particularly in seniors. We believe that the equilibrium could be reached with the support of telemedicine, education, and COVID-19 vaccination.
