If you’ve been following the news lately, you’ve noticed a lot of attention on Zika virus, an emerging mosquito-borne disease that’s spreading across the Americas. As of today, no cases of Zika have been found in Arizona, but several other U.S. states are reporting cases of Zika virus in travelers returning from countries where the [...]
ADHS Office of Infectious Disease Services published a report last week in the CDC Morbidity and Mortality Weekly Report describing concurrent outbreaks of West Nile virus and St. Louis encephalitis virus disease in Arizona.

Our state has experienced some powerful storms over the past month with the most recent hitting the Greater Phoenix Area last night. After the storm passes, the threat to public health can continue. Fortunately, there are simple actions you can take to prevent the spread of these health risks, including mosquito-borne disease, flood water runoff [...]
Back in July, Arizona’s first case of West Nile virus was confirmed in Maricopa County. Unfortunately, the disease hasn’t stopped there.

There are 40 different species of mosquitoes in Arizona, but only 2 transmit West Nile virus (WNV) to humans effectively, Culex tarsalis and Culex quinquefasciatus [...]
Disease outbreaks can come from anywhere. In Arizona we’ve had illness from contaminated pomegranate seeds from the Middle East, measles from Switzerland, salmonellosis from African dwarf frogs and cholera from Peru. More recently a Canadian traveler died of H5N1 after she returned home from a long trip to China. An exotic disease from another country is only [...]
Monsoon rain and humidity is great (at least I think so)… but with it comes mosquitoes that carry the West Nile virus. Every year since West Nile virus was introduced to AZ in ‘04, we’ve had human cases of West Nile Virus (meaning it’s endemic now). The total number of cases bumps around every year from [...]
The West Nile virus is making its annual visit to Arizona. We’ve had several cases now in Arizona (and 1 death) - mostly from the East Valley in Maricopa and Pinal Counties.
