I've heard that a lot of people get strep throat when the weather changes. Is that true?

Yes, it is true. Strep throat can be caused by viruses and bacteria. The most common cause of strep throat is Group A streptococcus (GAS). GAS is found in the throats of about 25% of adults and 10% of children. It's spread through close contact with an infected person or through droplets in the air. People who have frequent contacts with other people are at greater risk for getting strep throat.
