Conventional preventive measures during pandemic include social distancing and lockdown. Such measures in the time of social media brought about a new set of challenges -- vulnerability to the toxic impact of online misinformation is high. A case in point is the COVID-19. As the virus propagate, so does the associated misinformation and fake news about it leading to infodemic. Since the outbreak, there has been a surge of studies investigating various aspects of the pandemic. Of interest to this chapter include studies centring on datasets from online social media platforms where the bulk of the public discourse happen. The main goal is to support the fight against negative infodemic by (1) contributing a diverse set of curated relevant datasets (2) offering relevant areas to study using the datasets (3) demonstrating how relevant datasets, strategies and state-of-the-art IT tools can be leveraged in managing the pandemic.
