The new COVID-19 variant that scientists call JN.1 now makes up about 44.1% of COVID-19 cases across the country, the Centers for Disease Control and Prevention estimated Friday, marking another week of the fast-spreading variant’s steep rise in the U.S.
The increase is more than two times larger than the 21.3% that the CDC now estimates the strain made up of infections for the week ending Dec. 9, after Thanksgiving.
Comments closedThe severity of the infection doesn’t seem to make a difference. These complications can occur even in people who have very mild symptoms. The big surprise is how much this can affect younger people. Studies are showing that even young, active people can experience heightened risk of these complications.
High blood pressure, high cholesterol, diabetes, obesity: These are some of the well-known risk factors that can put people at heightened risk for heart attack and stroke.
Now some health experts say COVID-19 should be added to that list.
Comments closedOn December 23, a research team from Riken and other institutes announced the results of a study showing that after infection with the novel coronavirus, the heart may be persistently infected with the virus and the risk of heart failure may increase, even if the patient does not develop noticeable heart disease. The team points to the possibility of a sharp increase in the number of heart failure patients in the near future and calls for countermeasures to be taken.
Infection with the novel coronavirus occurs when a protruding “spike protein” on the surface of the virus binds to the ACE2 receptor on the surface of human cells. According to the team, the heart is more likely to express ACE2 compared to other organs. It has also been reported that some people infected with the novel coronavirus have reduced cardiac function, but the detailed mechanism is not known.
Comments closedNova Scotia has reached a solemn milestone, surpassing 1,000 COVID-19 deaths since the beginning of the pandemic.
“A thousand people in a province of a million people is a lot of humans and families that are missing people,” said Dr. Lisa Barrett, an infectious diseases doctor and researcher at Dalhousie University in Halifax.
Data released in the latest weekly respiratory watch report shows an additional nine deaths for the week of Dec. 10-16, bringing the total to 1,004 in the province.
Comments closedThe largest union in Nova Scotia says “extreme shortages” are expected in emergency departments during the holidays as many health-care workers are off work and there aren’t enough staff to cover absences.
Sandra Mullen, president of the Nova Scotia Government and General Employees Union, said the issue is especially pronounced at the Halifax Infirmary, one of the busiest hospitals in the province.
Comments closedWith COVID-19 cases and other respiratory illnesses rising across the region, some area hospitals have begun to bring back face mask requirements to halt the spread of infections.
Boston Medical Center said Thursday it would resume masking requirements in all patient-care areas beginning Friday. On Monday, the Dana-Farber Cancer Institute reinstated its mask requirements in all clinical and public spaces, and the Beth Israel Lahey Health system (BILH) updated its policies to require masking for all health care personnel upon entry to a patient room or bed space.
Comments closedStaffing shortages will close a Hamilton urgent care centre for two days at the same time city emergency departments are becoming increasingly congested with flu, COVID-19 and RSV patients.
With just 13 per cent of Hamiltonians getting a COVID shot in the past six months, local hospitals are bracing for the viral surge to continue climbing over the holidays.
Comments closedSnow might not be swirling in the UK but Covid is in the air this Christmas, data has revealed, with experts warning a new variant is on the rise around the world.
According to data from the Office for National Statistics (ONS) and the UK Health Security Agency (UKHSA), an estimated 4.2%, or one in 24 people, in England and Scotland had Covid on 13 December compared with 1.8% – or one in 55 – on 29 November.
Comments closedPeople are getting infected with COVID subvariant JN.1, but there are ways to protect yourself, your loved ones and the community over the holiday season.
Comments closedA rapid test importer landed an estimated $2 billion in federal contracts in 2021 and 2022, despite giving regulators incomplete data about its product’s accuracy, Global News has found.
A year-long investigation into federal procurement revealed that BTNX, a small rapid test supplier based outside Toronto, deleted dozens of specimens, or samples, from a study it submitted to Health Canada. That evaluation showed how well the company’s test detected COVID-19.
The deletions made BTNX’s test appear more reliable and sensitive than it really was, according to researchers Global News consulted.
Comments closedInfectious diseases expert Dr. Donald Vinh on the high number of viruses circulating in Quebec right now and how people can avoid them.
Comments closedWindsor Regional Hospital has declared a COVID-19 outbreak at its Ouellette Campus.
The outbreak was declared on its 8 West unit on Dec. 20, with a total of three patients affected.
Comments closedWith winter increasing the spread of three illnesses across the territory, Nunavut’s chief public health officer is urging people to take steps to protect themselves.
There are 75 confirmed cases of flu; 16 cases of RSV, or respiratory syncytial virus; and 12 cases of COVID-19 in Nunavut, Dr. Sean Wachtel said Tuesday.
But the actual number of people sickened is probably higher than that, he said.
Comments closedAccording to a small case-control study today in Scientific Reports, long COVID can affect heart rate variability (HRV) at rest and during deep breathing, adding to the evidence that persistent symptoms of the virus can be associated with cardiac and dysfunction of the autonomic nervous system (dysautonomia). This system regulates involuntary functions like heartbeat, blood pressure, and sweating.
The study, conducted by Brazilian researchers, included 21 patients with long COVID and 20 controls. Long COVID—defined by the authors as new or persistent symptoms experienced 12 or more weeks after infection—has been associated with heart palpitations, orthostatic intolerance (difficulty staying upright), dizziness, and syncope.
Comments closedWhen the coronavirus pandemic took hold in an unprepared U.S., many states like Ohio scrambled for masks and other protective gear. Supplies were so limited in 2020 that the state bought millions of medical gowns from a marketing and printing company and spent about $20 million to try to get personal protective equipment made in-state.
Three years later, as the grips of the pandemic have loosened, Ohio and other states are now trying to deal with an excess of protective gear, ditching their supplies in droves.
Comments closedAn analysis of 7 million contacts of COVID-19 patients in the United Kingdom estimates that most transmissions resulted from exposures lasting 1 hour to several days and that households accounted for 40% of spread from spring 2021 to early 2022.
Comments closedVaccinated children are less likely than unvaccinated children to develop long COVID, the myriad of symptoms that can last for months to years following a SARS-CoV-2 infection, according to a forthcoming US study1.
“This is really important data,” says Jessica Snowden, a paediatric infectious-disease specialist at the University of Arkansas for Medical Sciences in Little Rock. She says that in the United States, COVID-19 vaccines are recommended for children as young as 6 months old. But uptake has been low. “This will demonstrate to families how important it is that we protect our kids, not just from acute COVID, but from the longer-term impacts of COVID as well.”
