5 worrying virus families that could cause the next pandemic

The Commonwealth Scientific and Industrial Research Organisation has delivered a comprehensive report on how we should prepare for future pandemics.
The report identifies six key science and technology areas, such as faster development of vaccines and onshore vaccine manufacturing to ensure supply, new antivirals and ways of using the medicines we already have, better ways of diagnosing cases early, genome analysis and data sharing.
It also recommends we learn more about viruses and their hosts across the five most concerning virus families; these causes of disease could fuel the next pandemic.
We asked leading experts about the diseases they can cause and why authorities should prepare well.
