Yes.
Legal Immigrants are screened for health problems, and get all the vaccinations needed before they are allowed entry. Illegals just waltz in as if they own the place. No health screens, no vaccinations, and a hell of a lot of them are sick with stuff we had gotten rid of. stuff like Multiple drug-resistant tuberculosis is one of the most significant, and the chagas disease, dengue fever, polio, hepatitis A, B, C, MRSA, and it seems that Pertussis is on the list too.
