The emergence and re-emergence of infectious diseases necessitates knowledgeable and skilled health professionals. Massive open online courses (MOOCs) can provide the necessary training and education to address this need. MOOCs offer a flexible and accessible way for health professionals to acquire new skills and knowledge, which can be applied in real-world settings. By leveraging MOOCs, health professionals can stay up-to-date with the latest developments in their field and improve patient care. Furthermore, MOOCs can help bridge the gap in healthcare workforce development, particularly in low-resource settings. Overall, MOOCs have the potential to revolutionize healthcare education and improve health outcomes globally.
