Development And Validation Of An Isothermal Amplification Assay For Eastern Equine Encephalitis Virus, Mikayla D. Maddison Jun 2021

Development And Validation Of An Isothermal Amplification Assay For Eastern Equine Encephalitis Virus, Mikayla D. Maddison

USF Tampa Graduate Theses and Dissertations

Eastern Equine Encephalitis virus (EEEV) is a neurotrophic alphavirus for which there is no effective treatment or vaccine for humans. Periodic outbreaks in the Eastern United States represent an ongoing public health problem; Florida serves as the reservoir for EEEV for the rest of the country. Reverse transcription-polymerase chain reaction (RT-PCR) is the current gold standard for molecular diagnostic testing of the presence of EEEV in vectors. However, RT-PCR is technically complex and can be difficult for mosquito control districts to utilize. In order to provide a simple, cost-effective alternative for mosquito surveillance and control, a novel one step reverse …


Spatial And Temporal Determinants Associated With Eastern Equine Encephalitis Virus Activity In Florida, Kristi M. Miley Nov 2020

Spatial And Temporal Determinants Associated With Eastern Equine Encephalitis Virus Activity In Florida, Kristi M. Miley

USF Tampa Graduate Theses and Dissertations

Eastern Equine Encephalitis virus (EEEV) is considered the most pathogenic mosquito-borne illness in the United States. Human mortality has been estimated to range between 35 to 75%, with horses experiencing mortality rates greater than 90%. A large number of EEEV cases occur in Florida. Though we have come a long way since the first human infection was identified in the 1930s, there is still much to learn regarding the virus’s ability to maintain transmission year-round in Florida. Phylogenic studies support that Florida may serve as the geographic reservoir for EEEV. This research investigated spatiotemporal and ecological variables associated with risk …


Overwintering And Early Season Amplification Of Eastern Equine Encephalitis Virus In The Southeastern United States, Andrea Bingham Mar 2014

Overwintering And Early Season Amplification Of Eastern Equine Encephalitis Virus In The Southeastern United States, Andrea Bingham

USF Tampa Graduate Theses and Dissertations

Eastern equine encephalitis virus (EEEV) is a highly pathogenic arbovirus that causes severe disease, with a mortality rate of approximately 30-35% in humans and 80-90% in horses. Studies dating back to the 1930's have identified many of the epidemiological and ecological aspects of the virus. However, there are several aspects of EEEV's transmission cycle that remain unclear. In the northeastern states, transmission is seasonal, peaking in the late summer months, while in Florida there is year-round transmission of EEEV. Recent phylogenetic studies have also suggested that Florida may serve as a reservoir for EEEV; the virus may periodically be introduced …
