International Virtual Conference on Covid-19 and Its Effect is causing serious health, social and economic challenges, several of which are directly related to demographic factors. Given that older persons have a weaker immune system and are likely to have underlying chronic illness, they are particularly vulnerable to viruses like SARS-CoV-2. The severity of COVID19 thus does not depend only on a country’s health system and policy measures, but also on age structure, regional distribution and social behavior. COVID-19 is a premier event that brings together 250 academicians, public health specialists, health professionals, healthcare providers, researchers, scientists, policymakers, pharmaceutical developers, and health workers from countries around the world to present their latest research ideas, development, and applications in all areas of medical science.
