Considering some of my family members contracted Malaria (living on JD Miller Road, by the way), and known individuals who have died from West Nile contracted here, along with families who have lost loved ones due to Encephalitis, or been seriously and permanently damaged, I consider the increase of Mosquitoes to be a threat to not only humans, but also animals.
You are very, very prone to exaggeration. Although these news pieces are a bit dated, they show just how RARE it is for malaria to be contracted in the US.
From 1957 through 1994, 76 cases of locally acquired malaria were reported in the United States, the Centers for Disease Control and Prevention in Atlanta said.
The CDC Annual Summary of Malaria for 1996
(January 3, 1997) reports a total of 1,542 malaria cases
in the U.S. (Figure 2). This compares to 1,419 cases
reported in the U.S. in 1995. In
80 cases of malaria
reported in Florida, all but two were acquired outside
the US.
Of the more than 50 cases reported in 2007, 42%
reported travel to Africa and were predominantly infected
with P. falciparum. The remaining cases reported travel to
areas of Latin America or Asia and were primarily infected
with P. vivax.19
Also, mosquitoes do not spread hepatitis.
