UCLA Fielding School of Public Health team leading COVID-19 epidemiology study among animal health care professionals

Newswise — LOS ANGELES – A team led by Anne Rimoin, UCLA Fielding School of Public Health professor of epidemiology and Director of the UCLA Center for Global and Immigrant Health, has just launched an epidemiologic study to understand occupational exposure to SARS-CoV-2 and other pathogens in high-risk populations, including veterinary medicine and animal care/welfare workers. 

“Zoonoses are infectious diseases that spread from animals to humans. They are very common, both in the United States and around the world,” said Rimoin, concurrently leading a similar study of health care workers and first responders in Los Angeles County. “It is estimated that six out of every 10 known infectious pathogens in humans are zoonotic in origin, and three out of four emerging infectious diseases come from animals.”

To date there are seven documented coronaviruses that infect humans that have zoonotic origins, including SARS-CoV-1 (identified in 2003), MERS (2012), and the most recently-emerging coronavirus, SARS-CoV-2 (2019). Other recently-emerging zoonotic pathogens include highly pathogenic avian influenza (HPAI), bovine spongiform encephalopathy (BSE), and Nipah virus.

“As we have already seen with SARS-CoV-1, MERS and now SARS-CoV-2, emerging zoonotic pathogens have the potential to cause serious impacts to human health around the world as well as to the strength of the global economy,” Rimoin said. “That’s why this research is so critical right now; we urgently need to better understand which activities put us at highest risk for infection with these pathogens and propagate transmission from animal species to humans.” 

The study consists of a baseline questionnaire and monthly follow-up surveys assessing demographic information, potential clinical exposures to SARS-CoV-2, occupational risk factors for COVID-19 and other zoonotic diseases, mental health, and pandemic preparedness among animal care workers.

“Along with SARS-CoV-2, we hope to eventually expand the study to understand exposure to other coronaviruses and zoonotic pathogens,” Rimoin said. “This is an element of what should be a very focused effort at pandemic prevention as part of the response to COVID-19; these emerging threats are not going to disappear – if anything, the risks are only going to increase because of other global threats, including climate change.”

Longest known SARS-CoV-2 infection of nearly 300 days successfully treated with new therapy
University of Bristol

An immunocompromised individual with the longest known PCR confirmed case of SARS-CoV-2 infection, lasting more than 290 days, has been successfully treated with two investigational monoclonal antibodies (laboratory engineered antibodies). Clinicians and researchers from the University of Bristol and North Bristol NHS Trust (NBT) worked closely to assess and treat the infection and want to highlight the urgent need for improved access to treatments for such people with persistent SARS-CoV-2 infection.

Tecnología de inteligencia artificial y ECG puede rápidamente descartar infección por COVID-19
Mayo Clinic

La inteligencia artificial puede ofrecer un manera de determinar con exactitud que una persona no está infectada con la COVID-19. Un estudio internacional y retrospectivo descubrió que la infección por SARS-CoV-2, el virus que causa la COVID-19, provoca sutiles cambios eléctricos en el corazón. Un electrocardiograma (ECG) mediado por inteligencia artificial detecta estos cambios y puede servir como una prueba rápida y confiable para descartar la infección por COVID-19.
