It is the time of year when most people think that mosquitoes are a distant memory of summer past. West Nile Virus as well as other mosquito-borne illnesses and diseases don’t rear their ugly heads until the latter part of the mosquito season. The duration of the mosquito season varies from state to state, but typically mosquitoes are active from April until October. As 2011 draws closer to an end the CDC ( Centers for Disease Control and Prevention) released it’s findings for West Nile Virus for the present year-to-date on November 29th, 2011.
The findings show that for 2011, there have been a total number of 658 reported cases of West Nile Virus in the United States so far. This number reflects both neuroinvasive as well as non-neuroinvasive cases reported. Out of the 658 reported cases of West Nile Virus, 452 of those cases were diagnosed as neuroinvasive. Neuroinvasive West Nile Virus means that the disease affects the nervous system. This can include encephalitis which is inflammation of the brain and meningitis which is an inflammation of the membrane around the brain and the spinal cord. Meningitis can also lead to acute flaccid paralysis which is an inflammation of the spinal cord. Non-neuroinvasive cases reflect those patients that display less acute signs of West Nile Virus. In many instances the true number of those affected by non-neuroinvasive aspects of the disease can differ greatly from the actual number of reported non-neuroinvasive cases because a great deal of those infected do not seek medical attention when the disease is mild. In some of the mildest cases the patient many times does not even know they are infected. All of these numbers reflect both mild and severe cases confirmed as well as probable human disease cases occurring between January 1st, to November 29th, 2011.
Some of the states that show the highest level of reported cases include California with 151 confirmed West Nile cases and 8 deaths as a result of the disease. Next in line are Arizona with 58 confirmed cases, Mississippi with 51, New York with 43 and Illinois and Michigan tie with 33 confirmed cases. Nationwide the total number of deaths attributed to the disease totals 40. Only five states show non-human activity and those are Washington, Maine, Oklahoma, Oregon, and South Carolina. There is only one state which has reported no West Nile Virus activity either human or non-human for the year so far, and that is Maine.
This very important data reminds us of the importance of reporting any symptoms of the disease early. The CDC’s data also includes non-human infections and deaths reported by way of birds and other animals. If a high number of dead birds are reported in a specific geographical region it alerts the CDC and local health departments in that area to be on the alert for human cases that may present themselves.
In all our efforts to prevent and control mosquitoes and mosquito-borne illness, including nationwide, statewide and down to our own backyards we all hope each year that the impact of West Nile is less. These finding remind us that before we know long mosquitoes will begin breeding again and now is the time to plan for the upcoming season. The winter months give us a great opportunity to inspect our own surroundings and devise a mosquito control plan for the upcoming season to keep our families safe from mosquito-borne diseases like West Nile. Take time to inspect your property for areas that are prone to hold water such as lawn and patio furniture, children’s play areas, bird baths, planters left from spring blooms and even gutters to ensure they are free of debris. Check any screened areas or windows for damage or tears and have them repaired before spring arrives. Getting your property in tip-top shape before the arrival of the mosquito season will start a good habit and help keep you safe and bite free. Hiring a professional mosquito control company to ensure you are on schedule prior to the invasion of mosquitoes in April is also a great way to keep mosquitoes and the diseases they harbor out of your property and out of your life.
Mosquito Squad has a safe and effective way to keep mosquitoes and the risk of mosquito-borne illness out of your property. Our mosquito programs will begin at the dawn of the 2012 mosquito season.

As many of you already know West Nile Virus is a virus spread to humans and animals through the bite of a mosquito that has become infected with the virus through feeding off an infected bird. The question is how does the infected bird become infected with West Nile in the first place?
The cycle of West Nile begins with a mosquito which transmits the virus to a bird by way of the mosquito feeding from the bird, once the bird has become infected it serves as an amplifying host by developing levels of the virus that are sufficient enough to promote infection to other biting mosquitoes and thus pass it on to us and other birds and animals through the bite of the infected mosquito that fed from the bird, which was already initially infected by a mosquito to begin with. Although quite confusing, the cycle is also complex, naming the mosquito the guilty party where all aspects of infection from West Nile are concerned. This vicious cycle carries out over and over again and amplifies the disease in birds. The disease was first identified in Uganda in 1937 and since then has been commonly identified in the Middle eastern regions of the world, Africa and Western Asia. The virus had not been identified in the U.S. until an outbreak in New York in September, 1999. Since the New York outbreak more than 30,000 people have been reported with the virus and out of those 1,200 have perished from the virus. As of 2011 46 states have reported outbreaks of West Nile.
Many types of birds are likely to be infected with the West Nile Virus, but studies have shown that crows and blue jays are more likely to perish from the infection. In the 1999 New York area West Nile epidemic there was a huge die off of crows from the disease. Since this occurrence more than 200 species of birds found dead in the United States have tested positive for the virus. There is a detailed species list available through the CDC website that identifies the infected birds mortality rate from 1999 to present. You may visit here to view the list http://www.cdc.gov/ncidod/dvbid/westnile/birdspecies.htm The identification of these species were reported thanks to the help of the public reporting cases of dead birds to their state and local health departments whom is responsible for collection and testing of dead birds all across the US.
Birds serve as vectors, or intermediate carriers for the disease from the minute the infected mosquito bites them. In many cases sick birds won’t show any sign of the virus and in other cases birds can just fall out of the sky dead from the virus. When a human becomes infected with the virus it can take on three forms, one of which is an asymptomatic infection, the second is West Nile fever which is a mild febrile syndrome and the third is the most severe form of the virus which is called West Nile meningitis and West Nile encephalitis. Meningitis and encephalitis are neuroinvasive disorders which causes acute swelling of the membrane and lining of the brain and the brain itself.
Since there is no immunization for protecting us from West Nile the best way to lessen the chances of becoming infected with the virus is to minimize the risk of being bitten by an infected mosquito. Taking control of your property is key to controlling mosquito populations.
Here are some helpful hints to keep mosquitoes away…
- Keep your property mowed and free of debris and brush piles.
- Keep your bushes and plantings trimmed, tidy and avoid letting them get overgrown
- Make sure gutters and downspouts are free of debris that might cause moisture to collect
- Tip, toss out and turn over outdoor items that are not in use or those that may serve as reservoirs for moisture
- Check screened areas for rips or tears frequently and repair immediately to avoid mosquitoes from entering your home
- Frequently dump and refill bird baths or other areas where water can stand and serve as a place for mosquitoes to lay their eggs
- Have you property treated by a licensed professionall to kill and control mosquitoes
