CDC warns of earliest West Nile virus surge in over 20 years ahead of July 4 weekend
Federal health officials issued an urgent warning as West Nile virus spreads earlier and harder than any season in more than two decades. Through June, 48 cases were confirmed across 23 states, with 38 neuroinvasive cases and 4 deaths in Arizona.
As millions gather outdoors for the Fourth of July, the CDC warns that West Nile virus has arrived earlier and hit harder than any season in over 20 years. Through the end of June, 48 cases were confirmed across 23 states, the widest spread in a decade and nearly five times the historical average for this point in the year. 38 of the cases are the neuroinvasive form, which can reach the brain or spinal cord. Four people have died, all in Arizona, where Maricopa County alone accounts for 29 cases. There is no vaccine and no specific treatment, so covered skin, insect repellent, and draining standing water remain the practical defenses. Sources: CDC, CNN, KMVT.
