Hello, this is Health Check from the BBC.
I'm Claudia Hammond here for the next half an hour with the latest news from the world of health and medicine.
In a moment,
do some people have a label on their medical notes saying they're allergic to the antibiotic penicillin when they might not be?
And what impact could this have on antimicrobial resistance worldwide?
And to help me today, I have Dr. Graham Easton,
who's Professor of Clinical Communication Skills at Queen Mary University of London.
How are you?
Very well, thank you.
Well, you've got some good news for this week, which is something we always like.
What's that?
Yes,
really positive news from Burundi and Senegal in the fight to eliminate the world's leading infectious cause of blindness,
trachoma.
And there's a new study I want to ask you about too later on, Graham.
If you're expecting a baby,
you'll probably know there's roughly a 50-50 chance of having a boy or a girl, right?
Wrong.
New research has found if you already have three boys or three girls and you have a fourth child,
they're more likely to be the same sex as the first three.
