The returning diseases are;
3. Whooping Cough
5. Scarlet Fever
6. Bubonic Plague
The near eradication of these diseases in the United States during the twentieth century was a remarkable accomplishment of American civilization. Until recently, most Americans believed these diseases were gone from our shores for good.
But a politicized public health system, and a rise in the subsidized migration into the United States, however, have combined to reverse a century of progress.
The number of foreign-born residents of the country has increased by 31 million in three decades, from 11 million in 1986 to 42 million in 2015. Immigration to the United States during this period has come from Middle Eastern, African, Asian, South American and Central American countries where all these diseases are prevalent. The extra 31 million have arrived in a number of ways: approximately 3 million are refugees, 11 million are illegal immigrants, and the remainder are legal immigrants, asylees, and parolees.

These six “comeback” diseases are not the only ones of concern to America’s public health.
A number of other diseases, some of which are prevalent among foreign born residents of the United States and foreign visitors, also present a current problem, to varying degrees, including zika, flesh eating parasites—cutaneous leishmaniasis, ebola, leprosy, intestinal parasites, HIV, scabies, and diptheria.
