Lancaster man dies due to West Nile Virus, 2 more human cases in AV

WNV AV BirdsLANCASTER – The Los Angeles County Department of Public Health has informed the Antelope Valley Mosquito & Vector Control District (AVMVCD) about the first human death attributed to West Nile Virus (WNV) infection in the Antelope Valley. The victim was a West Lancaster man in his 70s, AVMVCD officials said.

The elderly Lancaster man was hospitalized with encephalitis in late September and died shortly thereafter.

“While most people infected with West Nile Virus show no symptoms, some individuals may experience severe symptoms and even die. Older adults and those with weakened immune systems are at greater risk for complications than others,” District Manager Cei Kratz said. “It’s important to remember that WNV can affect anybody. We continue to urge people of all ages to take precautions, such as removing stagnant water around their homes and using an insect repellent when outdoors, especially around dawn or dusk.”

The AVMVCD has also received reports about two more human cases, one in Lancaster and one in Palmdale. In addition, four chickens from three coops in Quartz Hill and Palmdale have tested positive for WNV infection.

This brings the WNV total in the AV to 15 human infections, including two asymptomatic blood donors, 25 chickens, five mosquito samples, and four dead birds.

As of October 10, the CA Department of Public Health has reported 237 human cases and six fatalities, as well as 1,142 birds, 2,440 mosquito samples, 425 chickens, 11 horses, and eight tree squirrels from 41 Counties that have tested positive for WNV.

West Nile Virus is transmitted by the bite of an infected mosquito. Although most people that are infected do not show any symptoms, West Nile Virus is a potentially debilitating disease. Even ‘mild’ cases of West Nile Fever can cause patients enormous pain and discomfort for months.

To keep mosquitoes away and stay safe, follow these tips:

Follow the 3 D’s (Drain, Dusk/Dawn, Defend/DEET)

  • Check your property for any standing water from sprinklers or thunder showers
  • Turn on fans to keep mosquitoes away
  • Keep screen doors and windows in good repair and close them
  • Don’t use bug zappers near your patio – they attract more mosquitoes than they kill

Also remember to:

  • Get FREE mosquito-eating fish (Gambusia affinis) for fish ponds, pools, and horse troughs.
  • Vaccinate your horses properly.
  • Report stagnant pools and other backyard sources to the AVMVCD.
  • Report dead birds by calling 1-877-WNV-BIRD (877-968-2473) or online at

    So we are supposed to follow the 3 D’s to prevent problems – what about the City of Lancaster?
    The city came thru a while back & put in a grate across the street at Albeck Ave & W. Ave J (across from Valley Central) to help drain the water but it is so plugged up & stagnant there that the water won’t drain. It is just standing water above the grate & has been that way for so long that the stench is horrible! Wonder how many mosquitos are hatching out of that?

      Is it too difficult to report it to the Antelope Valley Mosquito & Vector Control District at 661-942-2917, as the article suggests? Meantime, you could walk across the street to the Dollar Store and bring back a gallon of bleach? And finally, walk upstream to find the source of the water flowing to it and complain.

        They can come out & spray (which they do in our neighborhood very often) but the thing is… why is this so plugged up? Why isn’t the city maintaining these & cleaning them out?

          We are aware of the standing water in the gutters and have technicians who spray them every week to kill the mosquitoes in it. I know that doesn’t help the stench or the clogged drain. We are working with both cities to mitigate these kinds of problems, but their resources are spread thin and unfortunately they can’t clean out the drains as often as we would like. In the meantime we treat the water to reduce mosquito breeding from those sources.
          Most of the water in the gutters, ditches and basins in the AV is a result of people over-watering their lawns, resulting in “urban drool”. If you notice that it’s caused by something else (e.g. broken water line), please let us know so we can follow up on that.
