Do lots of people get tonsillitis, or is it unusual?

More in younger. We see it more often in younger people, but we can also see it in mature people. It depends on your immune strength as an adult. There are more attacks in children, but lot of adults get it. The causes are clasically streptococcus but also viruses and other bacteria. Usually antibiotics but sometime surgery - tonsilectomy. A dangerous situation with an abscess can occur - surgery then.
