My daughter's school sent a letter home yesterday saying that a child had pertussis at her school. any worries?

Yes.: Undervaccinated children can get a more severe form with complications, but even immunized children can get the mild form, manifesting as 3 months of constant cough.

Heads up normal: Schools will routinely notify parents when a significant contageous illness is reported in a student. Pertussis is one such illness that is worrisome to anyone who might get it but deadly to infants.General guidelines include recommending students in a classroom with more than one case receive medication to prevent further spread in the community.
