Health Risks of the Asian Tiger Mosquito

The Asian tiger mosquito is an aggressive biter, and feeds mainly during the day. It has a wide host range, including humans, domestic and wild animals and birds. This is a particularly aggressive insect during its feeding period and if it lands on you, the bug is so fast that you will have no opportunity to swat it.
In some southern cities, the tiger mosquito has become a major nuisance mosquito, the main one. Recapping, Asian tiger mosquitoes invaded the United States in 1985, and the species is widespread in over 20 states since then. Tiger mosquito is a vector of major diseases in Asia. In the United States, it was found to have LaCrosse encephalitis virus and West Nile virus, which can cause encephalitis (brain inflammation). However, it is presently unclear whether the tiger mosquito is a major vector of disease in the United States. West Nile virus was detected in that kind of U.S. Eastern Tiger Mosquito.
It is also important in veterinary medicine. For example, tiger mosquitoes are transmitters of Dirofilaria immitis, a parasitic worm that causes heartworm disease in dogs and cats year round. It is the potential vector of encephalitis, dengue (all four serotypes), yellow fever, filariasis and dog. This mosquito is a vector of LaCrosse encephalitis and Eastern equine encephalitis viruses.
The asian tiger mosquito is also a competent vector of encephalitis viruses regularly inspected two to California, St. Louis encephalitis (SLE) virus and western equine encephalomyelitis. However, recent studies suggest that levels of naturally infected avian hosts are generally insufficient to infect mosquitoes. Therefore, it might not be as big a threat for transmission of SLE in California, especially compared to the Culex mosquito. SLE is a viral disease that is often very severe in young children and the elderly by attacking the central nervous system, sometimes causing death. Yellow fever is a potentially deadly disease that has not been established in the United States or in areas adjacent to it. Although the tiger mosquito has been researched as a vector of pathogenic viruses from several relevant laboratories, there is no evidence to date that this mosquito has caused human illness in the United States
The tiger mosquito was responsible for the epidemic of Chikungunya in Reunion Island from the French in 2005-2006. In September 2006, there were 266,000 people infected and 248 died on the island. It was the transmitter of the virus in the first outbreak of the only Chikungunya fever in the European continent. This outbreak occurred in the Italian province of Ravenna, in the summer of 2007 and infected more than 200 people. It was concluded that the mutated strains of Chikungunya virus was directly transmitted by the Aedes albopictus, and the further spread of the disease in areas where the tiger mosquito lives is now feared.
