Cases of the West Nile virus are increasing in some parts of the country.
Officials in Los Angeles County have confirmed the first human cases there, while cases have also popped up in Maryland and Massachusetts.
In Arizona, there were a dozen cases of West Nile before heavy rains this summer. Now the state is reporting twice that, as rains coast-to-coast threaten to make outbreaks worse.
"If we keep experiencing more storms, more water, more accumulation of water and that water remains stagnant for around three to five days, that would be conducive to mosquito breeding, especially as we get warm temperatures," said Johnny Dilone, Maricopa County Arizona Environmental Services community relations manager.
While the chances of a person actually getting the virus are low, it's not a chance one should take.
Barbara Puls is still watching her brother-in-law recover from a case last year.
"Their prognosis for walking again is not very good because like his feet have sort of atrophied," Puls said of her brother-in-law.
Mosquitoes get the virus from feeding on infected birds. Then they pass the virus on to people through bites.
Across the U.S., preventing breeding in part relies on keeping the bugs away, and spraying for them is booming.
