Current clinical findings, effectiveness of control measures including vector control strategies, as well as interactions between SARS-CoV-2 and dengue viruses will be examined. Our webinar will focus on Thailand and Brazil, two very popular travel destinations that are highly endemic for dengue, as these countries currently fight the spread of COVID-19. 

This webinar is Series 1 of 2 of Dengue and COVID-19 focused webinars. You can find Series 2 on the webinar page of the LMS.
