Primary objectives and outcomes

The end of the COVID-19 pandemic remains out of sight. To overcome challenges in these times of uncertainty, Japan set the goal of leaving no one's health behind. JICA is taking a holistic approach to address issues related to the pandemic and health security in partner countries by focusing on prevention, precaution and treatment. Using this approach, it hopes to contribute to the protection of people's lives as the urgent target and build increasingly resilient societies.

In a situation where appropriate solutions are lacking,continuously sharing the latest research findings and the knowledge and experience gained through practice is imperative. Thus, this webinar invites distinguished researchers and clinicians in Japan to share the latest knowledge and experience in their respective fields and promote the efforts of each country in protecting people from COVID-19.
