The loss of smell and taste is now considered one of the major symptoms of Covid-19 and it can have a huge impact on people鈥檚 lives - especially when these senses do not return after someone has recovered from the disease.

Host Nuala McGovern hears from people in Costa Rica, the US and the UK about how it has affected their lives - from coffee that has become too pungent to drink and steak that tastes metallic - to being unable to smell fresh paint or the natural scent of a child.

Two parents in France and England also discuss the frightening impact of "Long Covid" on their teenage children, and three doctors in Mexico reveal how they are coping on the frontline after recently revised figures indicated that the number of Covid-19 related deaths is much higher than originally reported.
