Monday 9 August<\/strong><\/span>
\n09:00 Welcome:\u00a0<\/strong> Zoom room opens at 08h30 for participants. At 09h00 we will have a conference opening address by the Pro-Vice Chancellor (Research) of the University of KwaZulu-Natal, South Africa. Prof Abdool-Karrim (FRS) is a world leader in epidemiological research and is at the forefront of the fight against the pandemic in South Africa and at the WHO. He has a string of international awards and most recently was awarded the John Maddox Prize for 2020 jointly with Dr Anthony Fauci of the USA. In addition to his role at UKZN, Salim holds a joint appointment at Columbia University in New York. In his opening remarks he will make general remarks on Science and specific remarks on\u00a0 the global pandemic.<\/p>\n

CONTRIBUTED TALKS<\/span><\/h1>\n

Note that contributed talks will be 15 minutes duration with a further 5 minutes allocated for introduction and questions. Speakers are requested to keep strictly to the time limit.\u00a0 Flash Talks are 8 minutes duration and a further 2 minutes are allocated for introduction and questions. If speakers in a session do not arrive at the designated time, the Chair will call on the next speaker. If the original speaker arrives late, the talk may be accommodated after the last talk of the session on the discretion of the session Chair and provided that suitable time remains. In the event of connection problems, the Chair will bear with the speaker for a few attempts but if it is felt that more time is needed for the speaker to correct the connection issue, the Chair may suspend the talk temporarily and invite the next speaker. The original speaker may speak at the end if time remains and the connection issue is solved.<\/p>\n
