Claudia Hammond talks to Guardian health editor Sarah Boseley exactly one year after she and Claudia first talked on Health Check about a mysterious respiratory disease that had appeared in Wuhan in China – with 59 cases reported at that point. What have been the highs and lows of the world’s response to the coronavirus so far?

Alison van Diggelen reports from the USA on research which has found that on average the mental wellbeing of older people has held up better during the pandemic than that of younger generations, despite the mortality risk being much higher for the elderly. Researchers in California and Georgia have also looked at why.

Boston University’s global health epidemiologist Matthew Fox is Claudia’s guest of the week. They discuss the United States’ troubled Covid vaccine rollout, the long term health problems of conflict refugees, and how smartphones can improve a low-tech method of cervical cancer screening.
