You seem up to date on this rdcbn - can you tell me if the immunizations have quit working? Is that what's being said here?
Immunizations do not necessarily provide enough resistance to prevent you from getting a disease, it provides the population enough resistance to avoid wide spread epidemics.
However, in the case of whooping cough, the disease has been essentially eradicated in the US and the strains from South America seem to have mutated into more virulent forms to the point where the vaccinations are not as effective.
Since whooping cough has been largely eradicated here at home, people forget how bad it is and have elected not to vaccinate themselves and their families so we are losing our collective resistance to the disease which allows it to get a foot hold and reach cortical mass in the population at large.
Same with other nasty afflictions such as mumps, measles, diphtheria , polio and others that were finally eradicated after decades of hard fought effort on the part of CDC.
Lots of other horrible Third World diseases such as TB are also becoming both drug resistant and more sever and aggressive .
The resurgence of bed bugs and other largely eradicated parasites coming up from Central America compound the problem because many are disease vectors for the above disease and their eradication was a major reason why we were able to eradicate the diseases several decades ago.
The illegals are also bringing up pests that can destroy agricultural crops as well.
Their lack of basic concepts of sanitary conditions also help spread disease
Americans have forgotten the devastating epidemics, plagues and infestations which made life miserable for our grand parents and no longer understand that we are trying to stop more than illegal aliens at our borders.
