Cluster of legionnaires' disease cases found in downtown New Westminster, B.C. – CBC.ca

Published

The Fraser Health authority says it has detected a cluster of cases of legionnaires’ disease in central New Westminster. B.C.. 

Six cases have been discovered since June, with the most recent found last week. Two people are currently in hospital, but the health authority did not release their status.  

The source of the bacteria is still unknown, but Fraser Health says the exposure is around the downtown quay area. 

“It’s unusual to be seeing a number of cases concentrated like this, and that’s really the reason why we’re investigating and also wanted to notify the public,” said Dr. Aamir Bharmal, a Fraser Health medical health officer.

Bacteria found in the environment

Legionnaires’ disease is caused by a bacterium called Legionella pneumophila that is commonly found in freshwater, groundwater and soil. It can grow and spread in building water systems like cooling towers, hot tubs that aren’t drained, large plumbing systems and decorative fountains. 

People can get the disease when they breathe in small droplets of water in the air that contain the bacterium. 
 
Fraser Health says while most healthy people won’t get sick if exposed to Legionella, the elderly, smokers, people with chronic lung conditions and the immunocompromised are at high risk of becoming ill.

“We really are seeing people who are between the ages of 50 to 70, and many of them have underlying medical conditions,” said Bharmal.

Infected people may develop pneumonia and symptoms like fever, shortness of breath, severe fatigue, abdominal pain and diarrhea. 

The risk of death for people who develop legionnaires’ disease pneumonia ranges between 10 to 25 per cent, according to Fraser Health.

Symptoms develop in 1 to 19 days

Bharmal says the incubation period for the disease is 19 days, and while people typically start to develop symptoms within five days.

Anyone who has been in New Westminster within 19 days of developing symptoms and has a high-risk condition is urged to seek medical attention. 

Bharmal says the Fraser Health region normally sees between four to 15 cases of Legionnaires in a year.

“The fact that in just one city we’re seeing six cases in the last three months is the thing that is concerning, and we do need to figure out what the source is,” said Bharmal.

A team has been doing an environmental assessment trying to find out which buildings have cooling towers, air conditioning units and decorative water features.

Both residential and commercial buildings are being considered as possible sources of the bacteria.

Rapid 90-minute Covid-19 test shown to be highly accurate – Daijiworld.com

Published

on


London, Sep 18 (IANS): Researchers have created a 90-minute high speed Covid-19 test which does not require a laboratory and can be performed in cartridges smaller than a mobile phone with high accuracy.

The study, published in the journal The Lancet Microbe, revealed that the Lab-in-Cartridge rapid testing device, which can be performed at a patient’s bedside, was shown to have over 94 per cent sensitivity and 100 per cent specificity,

It means that it had a high level of accuracy and produced very few false negatives and no false positives.

To perform the test, a paediatric-sized nose swab from a patient is inserted into the device, which then looks for traces of genetic material belonging to the SARS-CoV-2 virus, which causes Covid-19.

A result is available within 90 minutes, compared to conventional Covid-19 testing which delivers a result in 24 hours.

“These results suggest the test, which can be performed at a patient’s bedside without the need to handle any sample material, has comparable accuracy to standard laboratory testing,” said study researcher Graham Cooke from the Kings College London in the UK.

According to the study, the device was used on 280 NHS staff members with suspected Covid-19, 15 patients in accident & emergency department with suspected Covid-19, and 91 hospital in-patients.

The samples from all individuals in the study were analysed on both the rapid-testing device, called the CovidNudge test, and standard hospital laboratory equipment – and then the results compared.

The research team assessed sensitivity and specificity.

Sensitivity is a measure of how well a test gives a positive result for people who have disease, and is an indication of how likely a test will produce false negative results.

Specificity, on the other hand, is a measure of a test’s ability to give a negative result for people who don’t have the disease, and is an indication of the likelihood of false positive results.

The percentage of those found to be positive for Covid-19 was 18 per cent.

The results showed 67 samples tested positive on the CovidNudge test, compared with 71 positive results against a range of standard laboratory machines, which represents the value of 94 per cent sensitivity.

4 people test positive for COVID-19 after attending night club last week – CBC.ca

Published

on


Public health officials in Toronto are warning of a potential COVID-19 exposure that originated at a local night club last week.

The city’s public health unit says four people who have tested positive for the virus attended Noir inside Rebel Entertainment Complex on Sept. 11.

They say anyone who was at the club between 10:30 p.m. that night and 2 a.m. the next morning may have been exposed.

Toronto Public Health says those who were at the club that night should monitor themselves for symptoms until Sept. 25, as well as wear masks in public and wash their hands regularly.

They say officials are working to trace anyone who had close contact with the four positive cases.

Toronto is one of three regions that’s been leading a major spike in the province’s COVID-19 case numbers in recent weeks, along with Ottawa and Peel Region.

Valley transmission rate among world's best | News | pentictonherald.ca – pentictonherald.ca

Published

on


A mid-month rise in COVID-19 cases can be traced back to British Columbians getting a little too close to one another over the Labour Day weekend, health officials say.

Another 139 cases, only three of which were in the region served by Interior Health, were announced province-wide between Thursday and Friday.

Since Sept. 15, the average number of new daily cases has been 153.

In the first two weeks of the month, the average daily number of new cases was 108.

“The cases we are seeing today are a direct result of how we spent our Labour Day long weekend. Let’s break the chain of transmission and turn this trend around,” Health Minister Adrian Dix and provincial health officer Dr. Bonnie Henry said in a joint Friday statement.

“No one intends to pass the virus onto friends or family, but it is very easy to do. It can take up to two weeks for symptoms of COVID-19 to develop and, in that time, we can inadvertently spread it to others.”

As of Friday, there were 1,803 active cases of COVID-19 in B.C. and another 3,075 who are under active public health monitoring because of their identified exposure to someone known to be infected.

Hospitalizations rose two, to 59, and 20 of them are in intensive care.

Across the province, 7,842 British Columbians have now been infected since the start of the pandemic, including 492 in the Interior Health region.

A total of 220 people have died in B.C. from COVID-19; two of those deaths occurred in the region served by Interior Health.

B.C. vs. Canada

A total of 330 people across the Okanagan have been infected by COVID-19 since the start of the pandemic, new figures from the government indicate.

That number represents 0.08 per cent of the region’s population of 377,000 people.

In the past two weeks, 13 people have been diagnosed with COVID-19 in the Okanagan.

The rate of transmission in the Valley is now among the province’s lowest, behind the West Kootenays and northwest B.C., and far below the rates being experienced in Vancouver and Surrey.

Every Thursday, the B.C. Centre for Disease Control produces a surveillance report covering a variety of COVID-19 data with infection statistics broken down by geography, patient age and likelihood of hospitalization.

The most recent report provides some context to the scope and effect of the pandemic beyond the daily case counts provided by Health Minister Adrian Dix and provincial health officer Dr. Bonnie Henry.

What often attracts the most media and public attention is the rising number of newly diagnosed COVID-19 cases.

Between Sept. 11 and Sept. 17, 833 new cases were confirmed provincewide, compared to 789 in the previous one-week period.

And the number of active COVID-19 cases across the province also rose in the past two weeks, from 1,412 to 1,705.

That number has been rising steadily since mid-July, and is now more than three times higher than active case counts in March, before the start of near-lockdown provisions ordered by the government.

But the surveillance reports also contain information that, while perhaps not reassuring exactly, give a fuller picture of how the pandemic is affecting British Columbians.

Here are some other highlights from this week’s COVID-19 surveillance report, with numbers accurate to Thursday:

— Cases have surged among people aged between 20 and 40, with that group now accounting for 44 per cent of all COVID-19 infections in B.C.

But only 10 per cent of British Columbians who’ve been hospitalized for the disease have been between 20 and 40, and no one in this age range has died of the disease.

Those numbers reflect the fact that reasonably healthy young people are simply much less likely to become seriously ill if they catch COVID-19.

— There are almost one million children and teenagers under 19 in B.C., but only 605 of them have caught COVID-19. That represents 0.06 per cent of the population group. Of the 605 children or teens who were infected, only five were hospitalized, none were treated in intensive care, and all have recovered.

— Of the 219 British Columbians who died of COVID-19 from the onset of the pandemic until this past Thursday, 28 per cent were over the age of 90, 69 per cent were over age 80, and 88 per cent were over age 70.
