Climate change, my foot. A massive increase in immigration from the Third World has led to an increase in Dengue. Malaria is next.
Ding, Ding, Ding, we have a winner. Malaria is already in the US, or rather, it is still in the US, though it was nearly wiped out it is coming back. Also, Google
Chagas Disease which is growing strong now in the US thanks to uncontrolled illegal immigration from Central America, the kissing bug in the US is now heavily infected, the main carrier.
Chagas disease is caused by Trypanosoma cruzi, a parasite related to the African trypanosome that causes sleeping sickness. It is spread by reduvid bugs and is one of the major health problems in South America. Due to immigration, the disease also affects people in the United States.
A massive increase in immigration from the Third World has led to an increase in Dengue. Nope. Dengue fever is NOT contagious. Illegal third-world immmigration did not spread Dengue; lack of the use of mosquito-killing DDT has led to an increase in Dengue.
Whooping cough, yes, that would be increased by illegal third world immigration. Dengue, no, unless you're referring to a massive increase in immigration of third-world mosquitos!!!
