The CDC has gone to its highest alert level due to concerns about the Zika virus.
From US News & World Report, February 8, 2016:
The Centers for Disease Control and Prevention said Monday that the agency’s command center is going to its highest level of alert, a measure reflecting growing concern about the prospect of Zika virus gaining a foothold in the mainland U.S
This represents the fourth time that CDC’s command center has declared a Level 1 alert. The other emergencies were Hurricane Katrina, the H1N1 flu threat in 2009 and the Ebola epidemic in West Africa.
So far, 50 cases been identified in the U.S., with several in Texas, Illinois, California and Washington, D.C. Five days ago, Florida Gov. Rick Scott declared a state of emergency in four counties, where health officials have diagnosed nine cases of Zika virus in travelers returning from Zika-affected areas.
“Once Zika got a foothold in Brazil, it spread like wildfire through Latin America, the Caribbean and Central America. Now it’s on our doorstep,” Vasilakis says. “There’s a lot of traffic between the U.S. and many countries in Latin America. If an infected individual ends up on our shores, it’s quite possible they could infect local mosquitoes and start a transmission cycle in the U.S., especially the southern U.S.”
“We already had three dozen infected individuals in the U.S. Starting in late March and April, when the weather becomes hotter and more rainy, the mosquito population will greatly increase in the Gulf states, increasing the risk,” he says.
Since it was first identified in Brazil last May, the virus has spread to more than 25 countries and territories in the Americas and Caribbean. It has been linked with a neurological ailment, called Guillain-Barre syndrome, which can cause paralysis, and at least 4,000 cases of a devastating birth defect, microcephaly. Babies born with microcephaly have malformed craniums and smaller brains, which often leads to lifelong cognitive impairment and disability.
