The JITMM theme this year is "Tropical Medicine 4.0 Effective Collaboration for an Impact on Global Health". The ‘4.0’ refers to the term used by the Thai government to talk about its new economic model, which promotes a knowledge-based economy based on creative and innovative thinking, inclusion across all society, and sustainable growth and development. We chose this theme to highlight the need for researchers and practitioners to think and act innovatively to solve Global Health problems. Many of the sessions this year will focus on the benefits of collaboration and inclusion and the importance of turning research into sustainable solutions. Through this 4.0 lens we will cover topics, breakthroughs and updates that are relevant across the tropical world.
