Biography

Gregory Glass focuses on understanding infectious disease systems: the agents, hosts and environmental sources. He especially is interested in detailing how changes in environmental conditions over space and time alter patterns of disease and discovering how those patterns can provide clues to what triggers disease emergence. Combining data from numerous sources, including remotely sensed imagery, with epidemiologic studies in statistical analyses, he aims to find ways to anticipate and intervene to prevent large-scale disease outbreaks.

Don’t blame the weather for fall COVID-19 spikes

Futurity  online

2020-11-23

Medical geographer Gregory Glass of the University of Florida contributed to the paper and compares what’s happening with COVID-19 cases in the US today to a wildfire. The first few waves of outbreaks spared many people who were susceptible to the disease, but enough susceptible individuals remained to fuel subsequent outbreaks.

As rats run rampant, experts warn of public health risk

FOX45 News  online

2020-09-22

"When you look for something in rats, you're almost certain to find it," Gregory Glass Ph.D. told FOX45 News. Dr. Glass, a professor at the University of Florida's Emerging Pathogens Institute, spent nearly 30 years studying rats in Baltimore while at Johns Hopkins University. He says rats pose a unique threat to the neighborhoods they infest.

Fact or fiction? Warmer weather slows down the coronavirus

Other forms of coronavirus, like the original severe acute respiratory syndrome known as SARS, and the Middle East respiratory syndrome, MERS, also appeared to thrive in colder temperatures and drier climates. “With MERS, it’s been pretty well-accepted that as temperatures go up and humidity goes up, the viruses remain viable in the environment for a shorter amount of time,” said Gregory Glass, a professor at the University of Florida and a member of the Emerging Pathogens Institute.

Validating Species Distribution Models With Standardized Surveys for Ixodid Ticks in Mainland Florida

Journal of Medical Entomology

Tick-borne pathogens are of growing concern. The U.S. Centers for Disease Control and Prevention (CDC) developed guidelines standardizing surveys of tick vectors to better monitor the changes in their occurrences. Unbiased surveillance data, from standardized surveys, are presumed critical to generate valid species distribution models (SDMs).

Modelling distributions of Aedes aegypti and Aedes albopictus using climate, host density and interspecies competition

PLoS Neglected Tropical Diseases

Florida faces the challenge of repeated introduction and autochthonous transmission of arboviruses transmitted by Aedes aegypti and Aedes albopictus. Empirically-based predictive models of the spatial distribution of these species would aid surveillance and vector control efforts. To predict the occurrence and abundance of these species, we fit a mixed-effects zero-inflated negative binomial regression to a mosquito surveillance dataset with records from more than 200,000 trap days, representative of 53% of the land area and ranging from 2004 to 2018 in Florida.

The interplay of movement and spatiotemporal variation in transmission degrades pandemic control

PNAS

Successful public health regimes for COVID-19 push below unity long-term regional Rt —the average number of secondary cases caused by an infectious individual. We use a susceptible-infectious-recovered (SIR) model for two coupled populations to make the conceptual point that asynchronous, variable local control, together with movement between populations, elevates long-term regional Rt, and cumulative cases, and may even prevent disease eradication that is otherwise possible.

Cocirculation of Two Orthohantavirus Species in Small Mammals of the Northwestern Ukraine

Journal of Wildlife Diseases

Rodent-borne hantaviruses have been reported in many of the countries surrounding Ukraine; however, to date we have no knowledge of the viral strains circulating in Ukraine within reservoirs such as the striped field mouse (Apodemus agrarius), the yellow-necked field mouse (Apodemus flavicollis), and the bank vole (Myodes glareolus). To determine the prevalence of hantaviruses in Ukraine, we captured 1,261 mammals, of which 1,109 were rodents, in 58 field sites within the province of Volyn in western Ukraine.

Seroprevalence of Old World Hantaviruses and Crimean Congo Hemorrhagic Fever Viruses in Human Populations in Northwestern Ukraine

Frontiers in Cellular and Infection Microbiology

In Ukraine, a retrospective review of clinical case reports by public health officials suggest that human cases of febrile illnesses associated with hemorrhage may be due to infections of Crimean-Congo hemorrhagic fever virus (CCHFV) and Old World hantaviruses. In a serosurvey of 966 healthy individuals in the Lviv Oblast, Ukraine, bordering Poland, we found that 1.6% showed cross-reactivity to hantaviral antigens by an immunofluorescence assay (IFA) and 1.7% of the study participants had antibodies cross-reactive to CCHFV by enzyme-linked immunosorbent assay (ELISA).
