New research reveals that intense COVID-19 viral exposure may diminish the shielding effects of vaccination and previous infection, resulting in “leaky” protection.
Antibodies to SARS-CoV-2, the virus that causes COVID-19, were present in the blood of 96.4% of Americans over the age of 16 by September 2022.
For their study, the investigators, who are also members of UF’s Emerging Pathogens Institute, evaluated population normalization factors, which are used to determine the relative human fecal contribution in a sample. With this information, scientists can control for fluctuations in the population contributing to a wastewater sample throughout time while quantifying the SARS-CoV-2 wastewater concentrations.
University of Florida researchers are refining wastewater surveillance techniques—a public health tool dating to the 1940s—to monitor cities, neighborhoods, and individual buildings for traces of COVID-19, fentanyl, and pesticides.
A UF mathematician collaborates with Yale School of Public Health researchers to evaluate the agreement of results between PCR testing and 18 commercially available rapid antigen tests for decision-making in remote work settings on when to end an individual's quarantine.
UF researchers find particles from virus that causes COVID are transported beyond quarantine spaces due to airborne nature.
UF researchers determined how long children remain infectious with the omicron viral variant after receiving a positive test result for SARS-CoV-2.
UF medical geographer Sadie Ryan makes the case that we need to better study human-to-wildlife viral transmission factors to better understand "spillback" events. How do we know when spillback will threaten species conservation — or fuel the next pandemic?
UF researchers updated their model projecting how an omicron-driven surge may unfold in Florida over the next few weeks and months. (This version supersedes the model information published Dec. 17, 2021.)
UF researchers created a model projecting how various omicron-driven surge scenarios may unfold in Florida over the next few months.
