(Press-News.org) TORONTO, Jan. 18, 2024 – The 2022 FIFA World Cup ended with a tight win for Argentina over France on penalties, but it was also a triumph for SARS-CoV-2 with a significant jump in the number of cases, some of which York University researchers say could have been prevented.
New research published today and led by York used the 2022 FIFA World Cup as a case study to help determine the best ways to mitigate virus spread and hospitalizations at mass gatherings in the future. A technique was used to sample initial conditions stemming from possible matches held between visiting teams, which then formed the basis of independent simulations of each game.
The paper, Modelling disease mitigation at mass gatherings: A case study of COVID-19 at the 2022 FIFA World Cup, was published in the journal PLOS Computational Biology.
Lead author of the paper, York postdoctoral fellow Martin Grunnill, and an academic-industrial collaborative team, including Faculty of Science Distinguished Research Professor Jianhong Wu, found that pre-travel screenings did little to prevent infections and hospitalizations.
Pre-match screening of spectators and match staff, however, with either a rapid antigen test half a day before or with a reverse transcription polymerase chain reaction test one and a half days before a match, was more effective than pre-travel screening. The researchers found doing both pre-travel and pre-match testing had even better outcomes, but what worked best was ensuring all visitors had a COVID-19 vaccination, a second or booster dose, within a few months of departure to the tournament.
“That precaution reduced the rate of infection and particularly the rate of hospitalizations,” says Grunnill.
Prior to the FIFA World Cup, COVID-19 cases and hospitalizations were declining in Qatar but began to rise during the tournament peaking at the beginning of the quarter final.
“The ambitious goal of the partnership research includes developing modelling technologies that can be used to assist in the preparation of major mass gathering events, whether religious or sports related in nature or a major festival,” says Wu. “We hope these platforms can be used to provide input into how to help manage respiratory infection risk for the next FIFA World Cup, hosted by North America, and the Olympic Games in Paris this summer.”
Wu points out that even before COVID-19, large events attracting tens of thousands of people spurred the spread of communicable diseases, sometimes globally.
“In the case of international events like the FIFA World Cup where visitors come from all over the world and return home, there is a higher chance of infections spreading beyond the host country,” says Grunnill.
The work is part of an on-going York-Sanofi collaborative project, funded by the Natural Science and Engineering Research Council of Canada, that aims to developing a generic modelling framework tailored to specific events involving intensive social-economic activities to support preparing those events with minimal risk of disease outbreak and spreading.

Reston, VA—A novel imaging approach, 68Ga-pentixafor PET/CT, has been shown to accurately identify sub-types of primary aldosteronism (an adrenal gland disorder), outperforming traditional methods for diagnosis. Reported in the January issue of The Journal of Nuclear Medicine, this detailed imaging technique provides a clearer picture of the adrenal glands, helping doctors decide more confidently whether surgery is the right option for patients.
Primary aldosteronism is an endocrine disorder that occurs when the adrenal glands produce too much of the hormone aldosterone, frequently ...
An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study, recently published in the journal PNAS, reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics.
"The exceptionally slow pace of genomic evolution sets these plants apart," said Dr. Fay-Wei Li, a professor at the Boyce Thompson Institute and a senior author of the study. ...
Temperature, day length and humidity have been found to be linked to the increased spread of a diarrhoeal illness a new study from the University of Surrey reveals. The findings could help predict further outbreaks of the illness, potentially leading to better preparedness within health services.
During this unique study, researchers led by Dr Giovanni Lo Iacono, investigated the impact of weather on the transmission of campylobacteriosis, a bacterial infection which can cause diarrhoea and stomach pains. According to the World Health Organisation, Campylobacter infections are the most common causes of human bacterial gastroenteritis in the world. Infections are generally ...
Scientists have developed two agents, made of therapeutic nanoparticles and antibodies, that could be given to patients shortly before a blood draw to allow physicians to better detect tumor DNA in blood using a technology called liquid biopsy.
Liquid biopsies promise to transform how cancers are diagnosed, monitored, and treated by detecting DNA that tumors shed into the blood. But the body presents a significant challenge. Immune cells in the liver and DNA-degrading enzymes in blood remove circulating tumor DNA from the bloodstream within minutes, making this DNA difficult to capture and detect in a blood test.
To overcome this, a team from the Broad Institute of MIT and Harvard ...
A fungal pathogen, Rosellinia necatrix, that attacks plants, produces antimicrobials to combat the plant-hosted bacteria that would otherwise inhibit its infection success.

CAMBRIDGE, MA -- Tumors constantly shed DNA from dying cells, which briefly circulates in the patient’s bloodstream before it is quickly broken down. Many companies have created blood tests that can pick out this tumor DNA, potentially helping doctors diagnose or monitor cancer or choose a treatment.
The amount of tumor DNA circulating at any given time, however, is extremely small, so it has been challenging to develop tests sensitive enough to pick up that tiny signal. A team of researchers from MIT and the Broad Institute of MIT and Harvard has now come up with a way to significantly boost that signal, by temporarily slowing the clearance of tumor DNA circulating in the bloodstream.

The cost of climate change may be six months off the average human lifespan, according to a study published January 18, 2024, in the open-access journal PLOS Climate by Amit Roy from Shahjalal University of Science and Technology and The New School for Social Research, U.S.
Temperature and rainfall — two telltale signals of climate change — cause myriad public health concerns, from the acute and direct (e.g., natural disasters like flooding and heat waves) to the indirect yet equally devastating (e.g., respiratory and mental illnesses). While impacts like these are observable and well documented, existing research has not established a direct link between climate change and life ...
AMHERST, Mass. – Tuberculosis, caused by the bacterium Mycobacterium tuberculosis (Mtb) kills upwards of 1.6 million people a year, making it one of the leading causes of death by an infectious agent worldwide—and that number is only growing larger. How, exactly, Mtb evades the immune system isn’t yet known, but a collaborative team of researchers from the University of Massachusetts Amherst and Seattle Children’s Research Institute recently discovered something surprising: prior exposure to a genus of bacteria called Mycobacterium seems to remodel the first-line defenders in the body’s immune system. Furthermore, how ...
