CONOZCA LOS ZANCUDOS Y EL VIRUS DEL NILO
OCCIDENTAL Los zancudos son algo más que
molestos hoy existen numerosas enfermedades
causadas por sus picaduras. Una de ellas, el
virus de Nilo Occidental, es relativamente nueva
en los Estados Unidos. El virus del Nilo fue
identificado originalmente en 1937 en Uganda. Hoy
se ha extendido por toda África y Medio Oriente,
parte de Europa, Rusia, India, Indonesia y
Australia. En los Estados Unidos apareció por
primera vez en la ciudad de Nueva York en 1999.
Desde allí se propagó rápidamente a todo el país.
En la mayoría de los casos, el Virus del Nilo no
presenta síntomas, o bien, puede causar sólo una
leve afección con síntomas similares a los de la
gripe. Con menor frecuencia, el virus puede
causar encefalitis o meningitis que constituyen
una grave amenaza para la salud.
