FIGURE 6-11 Reported Cases of Dengue Fever:
1980 -- 1999
In 1922, there were an estimated 500,000
cases of dengue fever in Texas. The mosquitoes that transmit this viral disease
remain abundant. The striking contrast in incidence in Texas over the last two
decades, and in three Mexican states that border Texas, illustrates the
importance of factors other than climate in the incidence of vector-borne
diseases.
