Coronavirus ogun launches mobile app to aid information sharing among health workers

I think there may be a mistake here. Ogun is a state in Nigeria, not a medical organization or a person who can launch a mobile app. Additionally, the coronavirus is a global pandemic that has affected many countries, not just Ogun state.

However, I assume you meant to say that the Ogun State Government or a healthcare organization in Ogun state has launched a mobile app to aid information sharing among health workers.

If that's the case, here's a rewritten version:

The Ogun State Government or a healthcare organization in Ogun state has launched a mobile app to aid information sharing among health workers in the state. The app aims to facilitate the exchange of information, updates, and best practices among healthcare professionals, enabling them to better respond to the COVID-19 pandemic and other health challenges in the state.
