If you are at higher risk of developing rheumatic fever, you must check a sore throat early and get treatment for strep throat with antibiotics. Without treatment, strep throat can cause rheumatic fever, which can damage your heart.
If you are not at higher risk, rheumatic fever is extremely unlikely for you even if you have a sore throat, so you do not need a swab test.
If you feel very unwell, have a high fever, or just have questions, call:
