LAS VEGAS -- Another person in southern Nevada has contracted the West Nile virus, the Southern Nevada Health District reported Monday morning.

The only information released about the person is that he or she is more than 50 years old. The case is believed to be the more serious neuroinvasive form of the virus. Five people now have contracted the virus in southern Nevada this year, including one person who died.

The health district also reports that mosquitoes carrying the virus were found in the 89122 ZIP code in the east valley. The mosquitoes previously had been spotted in the 89014 area of Henderson.

People supporting immigration reform rallied in front of Republican Representative for Nevada's 3rd District Joe Heck's office Tuesday morning.

The Nevada State AFL-CIO, PLAN, Mi Familia Vota, Dream Big Vegas and others delivered petition cards signed by people living in Heck's constituency in support of the immigration reform bill already passed by the U.S. Senate.

"We're dropping off petition cards from constituents that say their personal story of why they support immigration reform. They urge him to act as a leader within his own party, especially when the GOP meets tomorrow to discuss immigration reform," state coordinator for Mi Familia Vota Marisol Montoya Herrera said.

The legislation is now set to go before the U.S. House. The bill would increase border security, track people overstaying their visas, and crack down on employers hiring undocumented workers.
