Two city workers get certified and are ready for insect control in Granbury.
The City Council and City Mayor Nin Hulett acknowledged Aaron Heathington, and Heather Walls during February 6 council meeting for their time and effort spent investing in professional education, and receiving a Pesticide Applicator License which helps to improve the services the City provides and will allow for spraying of mosquitoes.
Mosquitoes can cause sickness and death through the diseases they can carry but which ones threaten us here Granbury both currently and potentially. Apart from disease, mosquitoes also cause nuisance problems for rural home owners and ruin recreational activities such as hunting and outdoor sports. In extreme situations high levels of nuisance mosquitoes can pose a threat to livestock and wild animals as well. The economic impact of the problems that mosquitoes cause is staggering for such a tiny little insect. For even more information on mosquito borne diseases you can check out this article from AMCA.
Mosquito Borne Disease / Is it a problem?
Mosquito borne diseases in Granbury: what you need to know!
West Nile Virus
West Nile Virus first arrived in the United States in 1999 in the New York area, since then it has spread rapidly covering virtually every part of the country. WNV most often starts out as a bird disease, it is then maintained and passed around from bird to bird in the wild by mosquitoes. Humans are infected when a mosquito that has fed on an infected bird then turns around and feeds on a human. WNV is not transmitted from human to human but rather from bird to mosquito to man, with man being an accidental or dead-end host. People over the age of 75 are at the greatest risk for succumbing to the severe form of the disease known as neuroinvasive WNV.
Most healthy persons who contract the disease will experience the less severe form of the disease known as West Nile Fever and make a full recovery.
St. Louis Encephalitis
Saint Louis Encephalitis is another arborviral disease found commonly in the United States. Much like West Nile Virus SLE is maintained in the bird population by mosquitoes with man being an accidental or dead end host. As with WNV man is infected when a mosquito that has fed on an infected bird also feeds on a human host. SLE can affect persons of any age however the effects are usually far more severe in those above 60 years old.
The most severe SLE epidemic in recent times was the one that rolled through the Mississippi River Valley in 1975. A total of 1,941 human cases
were recorded 95 of which resulted in death. The most severe outbreak of SLE in Louisiana to date occurred in 2001. The outbreak which consisted of 70 cases happened in Ouachita parish and was centered in the city of Monroe. West Baton Rouge Parish recorded SLE positive mosquito pools both in 2006 and 2007 but no human cases.
Eastern Equine Encephalitis
Eastern Equine Encephalitis much like WNV and SLE
Eastern Equine Encephalitis is a viral infection maintained in the wild by a bird to mosquito to bird cycle. Horses are involved with man as dead end host meaning they cannot transmit the disease between themselves. Of the many mosquito borne diseases EEE is the deadliest mosquito borne disease to occur in the US with a 30% fatality rate for those infected. Half of those who survive the infection are stricken with various degrees of mental disability and paralysis. People younger than 15 and those older than 50 are the most prone to infection although EEE can affect persons of any age.
A major outbreak of EEE struck Louisiana in 1947 when the virus caused disease in over 15,000 horses and 15 human cases resulting in 7 people dead. Since that outbreak understanding of the transmission cycle in the wild and the creation of a vaccine for horses has resulted in much less infections for horses and humans. Although incidents of disease in humans has been low in recent times EEE still remains a deadly mosquito borne disease for both horses and man.
