Abstract

The novel coronavirus (COVID-19) pandemic has had a devastating impact on the global population, with over 100 million cases and 2 million deaths reported worldwide. This novel virus outbreak has challenged the economic, medical and public health infrastructure of China as well as other countries remarkably the neighbors. Time alone will tell how the virus will impact our lives here in Bangladesh. The pandemic of COVID-19 has challenged our existing knowledge, laws, and regulations and forced us to take measures as far as complete lockdown in various parts of the world. The high death toll of COVID- 19 has stressed the need for prompt research and dissemination of updated information. This review summarized the scopes and developments of COVID-19 diagnosis tools and therapeutic options and also discussed the prevention and controlling steps considering an apparently upcoming second wave of infection. While the world is in search for a cure, it is recommended that countries should make use of existing scientific tools to develop models to predict community-based outcomes prior to make decisions. Healthcare workers must be supported with modern and effective facilities and remain updated with the up-to-date knowledge and practical skills. This paper provides an overview of the current state of the pandemic, including the epidemiology, clinical features, diagnosis, treatment, and prevention of COVID-19. It also discusses the economic, social, and psychological effects of the pandemic, as well as the challenges posed by the virus to global health systems.
