More than four years after the start of the Covid pandemic, the virus is showing no signs of fading away. This week, the World Health Organisation warned, in fact, that coronavirus is making a comeback, with 84 countries reporting an increase in positive test rates.

For an in-depth look at how the world is coping with the disease, Claudia Hammond speaks to immunologist Professor Danny Altmann from Imperial College London to ask what the future might hold.

Claudia is also joined by global health journalist Andrew Green to discuss whether Covid conspiracy theories are leading to a rise in AIDS denialism.

We hear the latest developments on the spread of the mosquito and midge-borne Oropouche virus, as cases of the disease are confirmed to have been found in Europe for the first time.

And as many of Europe’s major football leagues prepare to get underway again this week, we hear about the tobacco product snus that’s proving to be particularly popular with footballers, and whether it could give them an edge or pose a health risk.
