If you have a severe sore throat and want to prevent passing it on to your baby, there are a few things you can do. It's important to see a doctor if you have a high Centor score to get antibiotics to help with the sore throat and reduce the risk of transmission. Regardless of your score, practice good hygiene by washing your hands regularly, especially before touching your baby. Remember to cough into your elbow and clean any surfaces that come into contact with your baby frequently. These measures can help prevent passing on any illness to your newborn.
