<human>: I've heard that a lot of people get strep throat when the weather changes. Is that true?
<bot>: Yes, it is true. Strep throat is caused by bacteria that live in your mouth and throat. When you have a cold or other illnesses, these bacteria can spread to your tonsils and cause strep throat. The symptoms of strep throat include sore throat, fever, swollen lymph nodes, red and swollen tonsils, and white patches on the back of the throat.
