Following three deaths linked to the deadly hantavirus disease on a cruise ship this month, the scientific community is racing to answer the many unknown questions surrounding the outbreak.

Tom Whipple speaks to Dr Emma Hodcroft, an epidemiologist at the University of Basel and co-founder of Pathoplexus, an online database of pathogen genomes, to explore what the new hantavirus genomic sequences can tell us.

He also hears from Dr Nicole Luri, Executive Director of Emergency Preparedness and Response from the NGO The Coalition for Epidemic Preparedness (CEPI), to hear what steps would be taken if the hantavirus strain had the potential to become a pandemic, and how far their "100 days" mission has come.

With less than a month until the men’s football World Cup kicks off in the United States, Canada and Mexico, there are warnings from climate scientists that football’s global governing body FIFA needs to do more to combat the risks from the high temperatures both players and fans are expected to face. We speak to Dr Theodore Keeping from the World Weather Attribution team at Imperial College London to hear about the predicted conditions and the concerns they are raising.

Plus, mathematician Kit Yates from the University of Bath brings us his pick of the week’s science news you might have missed, including new hearing technology that might help you follow conversations in rowdy parties.
