The G20 countries have made several efforts in strengthening the global health architecture. Here are some key factors contributing to their initiatives:

1. Collaborative Partnerships: G20 countries have actively sought to establish partnerships with international organizations, such as the World Health Organization (WHO) and the World Bank, to coordinate and strengthen global health responses.
2. Investment in Research and Development: G20 countries have increased investments in research and development to address global health challenges. This includes funding for developing new treatments, vaccines, and diagnostics for diseases.
3. Health Infrastructure: G20 countries have recognized the importance of strong health infrastructure to respond effectively to health emergencies. They have invested in improving healthcare systems, including building hospitals, training healthcare workers, and improving access to essential medicines.
4. Disease Surveillance and Early Warning Systems: G20 countries have prioritized the development and implementation of robust disease surveillance and early warning systems. This includes sharing information, data, and technical support to detect and respond to outbreaks quickly.
5. Health Security and Preparedness: G20 countries have made efforts to enhance health security and preparedness by strengthening national capacities for emergency response, developing contingency plans, and conducting exercises to test readiness in case of outbreaks.

These efforts by G20 countries contribute to the strengthening of the global health architecture, ensuring better global health outcomes and responses to health challenges.
