It’s estimated that by 2040, there will be three seniors for every two young people in Atlantic Canada, and as the population ages, more people will be in long-term care facilities. That means there is increasing need to improve infection control measures in these facilities.
A new research project at Dalhousie University is examining if UV-C lights can help to reduce respiratory viral infections, particularly in seniors.
“UV-C light is part of the sunlight spectrum. It has been used as an airborne disinfectant for over a century,” said Dr. Kenneth Rockwood, lead researcher and Professor of Geriatric Medicine at Dalhousie University.
But for the longest time, Rockwood said, it was used as a mercury vapour lamp, and that light is toxic, resulting in — more or less — sunburn of the skin and eyes.
Now researchers have found wavelengths that can still kill viruses without having negative impacts on people.
Lights have been installed in common areas of four units at Northwood and two units at Windsor Elms. Each of the facility’s two units will be equipped with UV-C lights and two units will have placebo lights that look like UV-C lights.

“We’re very keen to have started a controlled trial of UV-C light to see if it is another thing we can do to reduce the chance of COVID infection or respiratory viral infections generally,” Rockwood said.
Registered Nurses Ann Mann will be among those taking part in the study.
“I think it’s a real positive sign for Northwood that we’re participating in this ground-breaking research,” Mann said.
Mann will be monitoring residents on all four units everyday for symptoms of COVID or any other viral infection.
“As part of the research, I don’t know which units are placebo and true UV-C Lights so all units are being treated equally.”
The goal of the project is to determine if, and how much, UV-C lights can reduce the risk of infection. Staff will be carefully monitoring when or how frequently new cases of respiratory viral infections occur.
“We’re working with public health, with the labs at the QEII, and are hoping to deliver a highly scientific trial,” said Rockwood.
“It’s innovative. iIt’s being tested in a very responsible way, and is an example of how in this part of the world we’re really doing everything we can to make sure we’re very vigilant and compassionate in terms of what we’re offering.”
The lights were installed at the beginning of November. The study will run until the end of flu season.
WHO advises against using blood plasma of recovered patients as COVID-19 treatment – CBC.ca
The World Health Organization on Monday advised against using the blood plasma of patients who have recovered from COVID-19 to treat those who are ill, saying current evidence shows it neither improves survival nor reduces the need for ventilators.
The hypothesis for using plasma is that the antibodies it contains could neutralize the novel coronavirus, stopping it from replicating and halting tissue damage.
Several studies testing convalescent blood plasma have shown no apparent benefit for treating COVID-19 patients who are severely ill. A U.S.-based trial was halted in March after it was found that plasma was unlikely to help mild-to-moderate COVID-19 patients.
The method is also costly and time-consuming to administer, the WHO said in a statement Monday.
A panel of international experts made a strong recommendation against the use of convalescent plasma in patients with non-severe illness, the WHO said. They also advised against its use in patients with severe and critical illness, except in the context of a randomized controlled trial.
The recommendation, published in the British Medical Journal (BMJ), is based on evidence from 16 trials involving 16,236 patients with non-severe, severe and critical COVID-19 infection.
COVID vaccine clinics available this week – The North Bay Nugget
A number of appointments for COVID-19 vaccine clinics – including some for children five to 11 years of age – are available across the region this week.
Only individuals five to 11 years of age will be able to secure an appointment at a child and youth Clinic, although older siblings or parents will be able to receive an adult dose of the COVID-19 vaccine at these clinics if they are accompanying a child to their appointment.
The pediatric COVID-19 vaccine approved for use in five to 11-year-olds is not yet available at regular clinics. However, it is available at participating pharmacies throughout the district. Parents and guardians are encouraged to book an appointment at one of the participating pharmacies if they would like their child immunized this week and cannot secure an appointment at a clinic hosted by the North Bay Parry Sound District Health Unit.
Individuals are encouraged to bring a health card or another form of identification, if possible, as well as any required documentation for those with underlying health conditions eligible for a third dose. Eligible individuals who received their last dose before June 21 will be able to book and receive their booster dose this week.
Flu shots will also be available for those with COVID-19 appointments at the adult clinics this week.
Appointments are still available at the following clinics this week:
Parry Sound, Wednesday, child and youth clinic at Parry Sound High School (111 Isabella St., Parry Sound) from 4 to 8 p.m.

More than 12500 Waterloo Region kids aged 5-11 have had 1st dose of COVID-19 vaccine – cjoy.com
More than 12,500 Waterloo Region children aged five to 11 have had their first jab of a COVID-19 vaccine since they were first handed out 11 days ago.
Waterloo Public Health says 26.62 per cent of area residents of that age group’s estimated 48,000 have had their initial dose of a COVID-19 vaccine.
This number increased by 8.5 per cent from Friday, with Waterloo Public Health no longer updating its totals over the weekend.
The agency says there have now been 941,742 vaccinations done in the area, which is 7,303 more than it reported on Friday.
However, the number of those getting their second dose continues to climb at a slow pace as that total now stands at 455,372, 569 more than was announced 72 hours prior.
This means that 75.24 per cent of all residents in the region have now had two doses of a COVID-19 vaccine.
The youth vaccinations could not come at a more prudent time as there were a host of COVID-19 outbreaks announced at schools across Waterloo Region over the past few days.
There were five new outbreaks announced over the weekend with four of those coming at schools including Mary Johnston Public School in Waterloo, Sir Adam Beck Public School in Baden, Saint John Paul II School in Kitchener and Forest Glen Public School in New Hamburg. The fifth new outbreak was at an unnamed auto sales location.
In addition, Waterloo Public Health reported another 125 positive tests for the coronavirus on Monday, lifting the total number of COVID-19 cases in the area to 21,145.
This lifts the rolling seven-day average number of new daily cases up to 34.6. A week ago, that number was 24.7.
Another 70 people were also cleared of the virus, lifting the total number of resolved cases in the area to 20,549.
There have been no new deaths reported in the area in five days, leaving the death toll at 308, including one victim in December.
The region now has 282 active COVID-19 cases, the highest number that has been reported since July 12.
There are also 12 people in area hospitals, including two patients in need of intensive care.
Elsewhere, Ontario reported 887 new cases of COVID-19 on Monday, bringing the total case count in the province to 624,384.
Of the 887 new cases recorded, the data showed 373 were unvaccinated people, 24 were partially vaccinated people, 426 were fully vaccinated people and for 64 people the vaccination status was unknown.
According to Monday’s report, 139 cases were recorded in Toronto, 73 in Simcoe Muskoka, 60 in York Region, 60 in Peel Region and 55 in Ottawa. All other local public health units reported fewer than 50 new cases in the provincial report.
The death toll in the province now stands at 10,027 as three more deaths were reported.
