Wastewater surveillance became an important tool for detecting COVID-19 outbreaks in communities throughout the pandemic, and it continues to be used in search for coronavirus SARS-CoV-2 as well as other pathogens.

But it’s unclear whether current levels of government funding to monitor wastewater for SARS-CoV-2 will continue beyond next year. Experts are calling on the federal government to create a standardized system for wastewater surveillance to bolster and replace the patchwork being used today.

The chances of becoming infected with COVID-19 while hospitalized increased as the pandemic progressed, according to recent Canadian research.

In fact, significantly more Canadians became infected with hospital-acquired COVID-19 during the fifth and sixth waves of the pandemic — the first two Omicron waves from late 2021 until the spring of 2022 — than during earlier waves, according to the study published in the journal JAMA Network Open. Researchers looked at cases of patients hospitalized with COVID-19 between March 2020 and May 2022.

It was thought at first that the pediatric population was relatively spared from the long-term effects of COVID-19 after infection. But this changed rapidly with increasing reports and studies of pediatric patients not fully recovering from acute COVID-19.

Dr. Jennifer Hulme thought her COVID-19 infection was just “average.” She recovered in a matter of days and went back to work.

Several weeks later she was incapacitated.

“I woke up completely disabled, profoundly ill (and) completely changed from my previous self,” the Toronto emergency room doctor said.

Scientists Are Just Beginning to Understand COVID-19’s Effect On the Brain

The list of neurocognitive issues that Meropol’s team and other researchers must track is extensive: cognitive decline, changes in brain size and structure, depression and suicidal thinking, tremors, seizures, memory loss, and new or worsened dementia have all been linked to previous SARS-CoV-2 infections. In some cases, these longer-term problems occur even in patients with relatively mild COVID-19.

Study: Sperm counts decline even after mild COVID infections

Men recently infected with COVID-19 have decreased sperm counts for more than 3 months following even mild infections, and the sperm they do produce is less able to swim, according to new findings presented today at the annual meeting of the European Society of Human Reproduction and Embryology (ESHRE) in Denmark.

The findings are intriguing because men produce new sperm every 2 or 3 months, and the findings are based on semen analyses taken after 100 days, suggesting COVID does long-term damage to the male reproductive tract.

A study of people who were intentionally infected with SARS-CoV-2 has provided a wealth of insights into viral transmission — showing, for example, that a select group of people are ‘supershedders’ who spew vastly more virus into the air than do others.

Some may think COVID-19 affects just the lungs. What was found is that this new MRI technique that we created is very good at identifying changes to the brain due to COVID-19. COVID-19 changes the white matter in the brain.

According to a new study, rapid antigen tests may provide false negatives — suggesting that a person is infection-free, even though other parts of their respiratory tract are teeming with the virus. The researchers found that most people showed a delay of several days between when the virus first appeared in the throat or saliva and when it appeared in the nose. Importantly, 15 of the 17 study participants had high levels of the virus for at least a day prior to getting a positive result.
