If it was the case, we wouldn't have between 200 and 300 million cases of malaria every year, and we wouldn't have a million and a half deaths from malaria, and we wouldn't have a disease that was relatively unknown 50 years ago now suddenly turned into the largest mosquito-borne virus threat that we have, and that's called dengue fever.
Si fuera el caso, no tendríamos entre 200 y 300 millones de casos de malaria cada año, y no tendríamos un millón y medio de muertes por malaria, y no tendríamos una enfermedad relativamente desconocida hace 50 años y que ahora, de repente, se convierte en la mayor amenaza que tenemos de un virus transmitido por mosquito, la llamada fiebre del dengue.
