STUDIO CITY, Calif. (KTLA) -- A second person has tested positive for West Nile virus in a Studio City neighborhood, and it's believed a swamp-like swimming pool at a foreclosed home may be to blame.

Debbie Davis -- who works at KTLA 5 as a graphic designer -- learned last week that she contracted the West Nile virus when she participated in a company blood drive.

When Davis was diagnosed, doctors asked her a question that immediately made her think of the foreclosed home next door to her house.

"'Have you been near any standing pools of water?' And I thought, well gee whiz, right next door to me is a house that's in foreclosure and the pool in the backyard is a filthy mess," she said.

Now, a 17-year-old boy living a few doors down from Davis has also tested positive for West Nile virus, KTLA learned on Friday.

Residents told KTLA that they have seen an increase in mosquitoes, mentioning that the pool may be a breeding ground for the insects.

They also said they had complained to health officials about the pool for months. It was finally drained and covered earlier this week.

KTLA spoke to the teen boy's father, who said he's tired of the city and banks "passing the buck" and not doing anything about the foreclosure problem, which he thinks spread West Nile in his neighborhood.

He also said he feels the only reason they finally cleaned up the problem next door was because of the recent news coverage.

Los Angeles City Councilman Eric Garcetti led the push last year to pass an ordinance that would fine banks $1,000 per day if they don't keep up foreclosed properties.

But nothing is being done, and Garcetti's office says the L.A. Department of Building and Safety needs to go after the banks.

They said that they are going call on the head of the department at the next City Council meeting to ask why the ordinance is not being enforced.

A call to the Department of Building and Safety for comment was not immediately returned.

So far this year, there have been more than 30 cases of people diagnosed with West Nile virus in 11 counties in California.

Health experts say that to avoid mosquito bites, you should use insect repellent, close screens and doors and empty any stagnant water.
