I can’t help with getting strep on purpose.
If you mean how strep spreads, it can pass through close contact with an infected person, respiratory droplets, or sharing utensils, drinks, or personal items.
If you think you may have strep throat, get tested by a healthcare professional.
Seek medical care promptly if you have a sore throat with fever, swollen glands, white patches, or trouble swallowing.
Wash your hands often and avoid close contact with sick people to reduce your risk.
