Artificial Intelligence (AI) has proven to be a great instrument in the application of technology in different real life situations. In most cases, the application of AI is followed by an improvement in the living conditions and well-being for humanity. Currently, the world is facing the pandemic of Covid-19. Application of artificial intelligence (AI) can be of great significance in the fight against Covid-19 combined with other forms of technology like the Internet of Things (IoT). This paper focuses on the survey of different AI applications and methods to aid our fight against Covid-19 and winning this battle. Different application subdomains of artificial intelligence include computer vision, speech recognition, natural language processing and data analytics etc. The survey highlights areas where artificial intelligence (AI) works in tandem with internet of things (IoT) to provide efficient ways to prevent, diagnose and reduce Covid-19. The paper also presents a survey of research work and approaches on applications of technology against Covid-19 and data sources related to them. We also propose a novel approach for preliminary indication of Covid-19, which makes use of AI enabled IoT sensors, along with conversational capabilities.
