We hear from three people in South Africa, Australia and the US who share the unexpected social consequences - both positive and negative - of wearing face masks when you have a facial disfigurement or difference.

And we hear from a journalist in the Brazilian city of Manaus in Amazonas state, where hospitals have reported severe oxygen shortages. We also discuss with our coronavirus expert of the day, Dr Marc Mendelson in Cape Town, the new virus variants detected in Brazil.
