Symptoms of influenza and COVID-19 share a number of similarities
Region of Waterloo Public Health reported four new cases of the coronavirus on Wednesday morning.
Two are due to community transmission, while the other pair are tied to travel.
So far this week, there have been 12 new cases, and a total of 1,410 since March.
The number of active cases increased by three to 25, with two of those cases currently receiving treatment in hospital.
One more case has also been resolved, improving that total to 1,263.
A total of 119 local deaths have been linked to the virus, but there have been no additional deaths reported since July 17.
Meantime, an outbreak remains active at A.R. Goudie long-term care – a resident tested positive, but no more residents or staff have since it was first declared on August 3.
Here’s the provincial COVID-19 breakdown for Wednesday:
- 40,289 total cases (95 new)
- 49 people are being treated in hospital
- 36,590 resolved cases
- 2,787 deaths (one new)
Community case of COVID-19 linked to outbreak at Pembroke, Ont. high school – CTV Edmonton
A community contact connected to the COVID-19 outbreak at Fellowes High School in Pembroke has tested positive for novel coronavirus.
The Renfrew County and District Health Unit provided an update Saturday evening on the COVID-19 outbreak that closed the high school last Wednesday. Four staff members and a student at the school have tested positive for the virus.
The health unit says a community contact connected to the outbreak has tested positive for COVID-19.
“This is not a student or staff member at Fellowes High School, but has been identified through contact tracing,” said the health unit in a statement.
“They have been isolating since being identified as a high-risk contact.”
The Renfrew Country and District Health Unit says there have been no additional positive COVID-19 cases among students or staff at the school.
Acting Medical Officer of Health Dr. Robert Cushman told CTV News Ottawa on Friday that he will know more information on Monday about when the school may reopen.
Fellowes High School in Pembroke was the first school in Ontario forced to close due to COVID-19 cases.
COVID-19 roundup: Flu may be linked with coronavirus spread, RA drug could aid recovery | Daily Sabah – Daily Sabah
This week’s roundup of some of the latest scientific studies on the coronavirus and efforts to find treatments and vaccines for COVID-19 investigates the possible link between influenza outbreaks and the spread of the coronavirus, newly discovered proteins SARS-CoV-2 has that may be responsible for immune triggers and how other drugs can be utilized in the fight against this infectious disease.
Flu may be linked to coronavirus spread
Influenza outbreaks may be linked with the spread of COVID-19 infections, according to a European study.
The researchers created a mathematical model of transmission of the coronavirus in Belgium, Italy, Norway and Spain. It calculates that higher rates of influenza infections would be associated with increased coronavirus transmission in each of the countries, Matthieu Domenech de Celles of the Max Planck Institute for Infection Biology in Berlin told Reuters. He said the estimates, published Wednesday on the medical website medRxiv in advance of peer review, align with earlier research.
In Italy, he noted, higher rates of flu vaccination have been linked with lower rates of death from COVID-19. Also, he said, a U.S. study of nearly 11,700 people tested for COVID-19 found that those who had flu vaccines were less likely to have a positive test.
None of these studies proves that flu vaccines affect the spread of COVID-19 or an individual’s risk for it, and other factors might explain the associations. Still, de Celles said, in advance of “the upcoming ‘twindemic'” of seasonal flu and COVID-19 in the northern hemisphere, “our results suggest the need to increase vaccination against influenza,” which may not only reduce the burden of influenza but also limit COVID-19 cases.

Rheumatoid arthritis drug found to aid COVID-19 recovery
Hospitalized COVID-19 patients being treated with Gilead Sciences Inc.’s antiviral medication remdesivir recovered about a day sooner, on average, if they also received Eli Lilly and Co.’s rheumatoid arthritis drug baricitinib, clinical trial investigators found.
The trial, sponsored by the U.S. National Institute of Allergy and Infectious Diseases (NIAID), included more than 1,000 patients. The study also showed that compared to patients who did not receive the arthritis drug, those who did had better outcomes at 15 days after they enrolled in the trial. Based on the data, Lilly plans to discuss the potential for emergency-use authorization with the U.S. Food and Drug Administration (FDA). The company announced the results of the so-called ACTT-2 trial in a news release Monday. The results have not been formally published yet.
Experts tell when to test for COVID-19 antibodies
COVID-19 antibody tests – so-called serology tests – are widely available, but evidence of their usefulness is limited, the Infectious Diseases Society of America said as it unveiled new guidelines published earlier this month in the journal Clinical Infectious Diseases.
Antibodies to the coronavirus do not show up in the blood for quite a while after someone becomes infected, so serology tests are unreliable for diagnosing COVID-19 unless a patient has been sick for weeks, according to the guidelines.
The panel of authors, led by Dr. Kimberly Hanson of the University of Utah, listed three instances in which a test for antibodies to the coronavirus would be warranted. The first one is when doctors strongly suspect a patient has COVID-19 but gold-standard diagnostic PCR molecular tests that look for genetic components of the virus have been negative and at least two weeks have passed since the onset of symptoms.
The second is when a child has signs and symptoms of multisystem inflammatory syndrome, a life-threatening condition that has been linked with previous coronavirus infection. The third is when public health officials conduct so-called serosurveillance studies to track the proportion of the population that has been exposed to the virus.
Newly discovered coronavirus proteins may be immune triggers
Scientists have discovered 23 previously unknown proteins made by the coronavirus, including four that might be triggering patients’ immune system to act – or in some cases, to overreact – and cause severe illness.
For the most part, proteins in this new virus have been identified based on computational predictions and similarities with other coronaviruses. But these researchers took a different approach.
By tracking protein-producing “machines” in cells called ribosomes, they were able to map exactly which parts of the genetic code of the virus were being translated into proteins, study co-leader Yaara Finkel of the Weizmann Institute of Science in Israel told Reuters. Most of the newly discovered proteins probably have regulatory functions in the virus – that is, they help keep it active – except for the four “full-fledged proteins” that might be alerting the immune system to the presence of a foreign invader, Finkel and colleagues wrote in a study published in the journal Nature on Wednesday.
More work is required to determine the roles these proteins play in infection, Finkel said, but that knowledge could “lead to a better understanding of the progression of the infection, as well as better ways of either treating COVID-19 or preventing the dangerous immune over-response.”
Health unit prepares for possible ‘twindemic’ – The North Bay Nugget
When it comes to a possible “twindemic” – the arrival of flu season in the midst of the COVID-19 pandemic – “all you can do is expect the worst, plan for the worst, and hope for the best.”
Dr. Jim Chirico, medical officer of health with the North Bay Parry Sound District Health Unit, says there are “so many unknowns” about what this year’s flu season will look like.
The flu season in the southern hemisphere, which can provide indications of what will happen in the northern hemisphere, was very mild this year, but Canadians can’t take that as a true indicator of what will happen here.
“Was it mild because of the COVID-19 measures that were in place?” Chirico asks. “We don’t know. We don’t know how severe it might be.”
The flu normally starts to be felt in this region in the late fall, running until January. Canada has been weathering the COVID-19 pandemic since March, and there are no signs it will let up anytime soon. In fact, the number of cases across the country have been climbing over the past week.
Having two pandemics at the same time, Chirico says, can put more pressure on the health system as symptoms of influenza and COVID-19 share a number of similarities. That means the number of people seeking testing for COVID-19 could increase as the seasonal flu takes hold.
The flu, he says, affects children more, it appears, than COVID-19 does, but elderly residents are particularly susceptible to both.
Chirico advocates everyone possible get the flu vaccine when it arrives in the region. It helps reduce the possibility of contracting the flu and may reduce the severity of influenza, although it does not offer 100 per cent protection from contracting it.
“It protects not only you but those around you,” Chirico says. If we can reduce the number of flu cases, it will reduce the pressure on the health-care system.”
The health unit, he says, is working with primary health-care providers and pharmacies to make sure as many people who want the flu vaccine can get it. The health unit will be providing vaccination clinics, while the vaccine will also be available at doctors offices and at pharmacies.
Chirico notes that when the H1N1 flu was prevalent some years ago, the health unit was able to conduct “mass immunization clinics.
“So we have that experience” to fall back on and to prepare for the eventuality that it might be necessary again, he says.
“We do have plans in place to do that.”
He also believes that the measures put in place to protect against COVID-19 can help prevent a serious flu season.
“I really do believe those efforts will pay off. The same recommendations for COVID-19 will prevent the flu, as well.”
Those measures include wearing face masks, social distancing, regular washing or sanitizing of hands with soap and water or an alcohol-based rub, sneezing or coughing into your arm, not touching your eyes, nose or mouth, staying home if you feel unwell and, if you develop a fever, cough and difficulty breathing to seek medical attention.
‘Done very well’
“People have been very mindful” of following those measures, he says, and the North Bay-Parry Sound area has “done very, very well.
“I do believe all the efforts to reduce the impact of COVID will do as well with the flu because they are transmitted in the same way,” he says.
The region has reported a total of 39 positive COVID-19 cases since the middle of March. Thirty-seven of those cases have been resolved and one person is in self-isolation. One person has died of COVID-19 in the region.
Chirico also notes that there was “a very reduced number of cases” of influenza last year, compared to the previous four or five years.
The area has reported between 126 and 298 cases annually with “very little mortality” over those years, he says, although the number of total cases “is obviously likely more” because most people who get the flu don’t go for treatment.
According to JAMA, the Journal of the American Medical Association, both influenza and COVID-19 can present with fever, chills, headache, cough, fatigue and myalgias – muscle aches and pain, which can involve ligaments, tendons and fascia, the soft tissues that connect muscles, bones and organs.
Influenza differs in that it also generally features nasal congestion and sore throat, while COVID-19 can include shortness of breath and loss of the senses of taste and smell.
There are five COVID-19 assessment centres in the region. Appointments must be booked in advance.
The centres are located at:
• Hopital de Mattawa Hospital. Book an appointment by calling 705-744-5511 ext. 0
