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.
