BCCDC data dashboards help navigate respiratory illness season

The COVID-19 pandemic catalyzed surveillance efforts and enhanced our ability to monitor respiratory illness in near real-time.

​​​​​​​​Fall and winter are the time of year when we expect to see more respiratory illnesses circulating in British Columbia. We should all be familiar with the steps we can take to protect ourselves and others, prevent spreading sickness, and manage symptoms when we’re at home. 

The BC Centre for Disease Control (BCCDC) works with health system partners, including the Provincial Health Services Authority and regional health authorities, to collect and analyze information from different sources to give us a picture of respiratory virus activity throughout the province. SARS-CoV-2 (the virus that causes COVID-19) activity has been stable since October, but influenza A and respiratory syncytial virus (RSV) infections are currently rising.Three lab technicians wearing gowns and surgical masks look at a screen in a lab

“What we’re seeing this year is an increase in influenza and RSV activity, returning to levels we used to see before the COVID-19 pandemic,” says Dr. Aamir Bharmal, a Public Health Physician and Medical Director of the Public Health Response Division at BCCDC.​

“Some of the key things we look at are how many people are getting sick and having severe illness, how many people are going into their doctors for respiratory symptoms and what we’re getting from the lab data − what types of viruses are coming up.” 
 

The BCCDC recently updated its data tool for respiratory viruses​, making it easier to see which viruses are circulating in different communities and whether there are increases in infection or serious illness. Dr. Hind Sbihi is the Director of Data Science and Innovation in BCCDC’s Data and Analytics Services area, a team that helped establish the surveillance platform and contributes to the weekly reports.

“We’re able to use the dashboard to communicate on the subtypes of viruses that are circulating,” says Dr. Agatha Jassem, Program Head of the Virology Lab at the PHL. “This is important information, as it can affect patient management and inform vaccine strain match.”

Regular updates allow people and communities who could be significantly affected by these viruses to stay informed of their risk. The dashboard is also a tool for public health, provincial government and regional health authorities to monitor trends, identify outbreaks and be ready to act to help keep people safe.

“The dashboards have both key messages and data-rich visuals,” says Dr. Natalie Prystajecky, the Program Head for Environmental Microbiology at the PHL. “This makes it easy for those who want the “Coles Notes,” and offers in-depth analysis for those who want more detailed information.”​

Wastewater data on flu and RSV available to the public

The project started during the pandemic and previously covered the Lower Mainland, but the lab now receives samples​ from water treatment plants throughout the province. The wastewater project team has rolled out a new testing protocol to detect levels of the two mains strains of flu and RSV, in addition to ongoing monitoring of the virus that causes COVID-19.

“It’s really all about the accessibility of health data,” says Dr. Prystajecky, explaining that a blend of key messages, sophisticated analytics and user-friendly visualizations make it easy for anyone living in B.C. to consult the data tool and see what’s happening in their area.

“Mycoplasma pneumoniae, for example, is a hot topic this ye​ar,” says Dr. Hoang, explaining that the public health lab watches for unusual trends in B.C. and the possibility of antimicrobial resistance in the pathogens they’re monitoring.​

Tips to stay healthy this respiratory illness season

Dr. Bharmal says this year’s influenza vaccines appear to closely match the strains of influenza that are currently circulating in B.C. and emphasizes the importance of getting vaccinated. He says everyone six months and older should get a flu shot and additional doses of a COVID-19 vaccine, but it’s especially beneficial for children, as many younger children weren’t previously exposed to different strains of influenza during the pandemic. Vaccines are also strongly recommended for older people with health complications, people who are immunocompromised, and anyone in regular contact with those at higher risk.

Here are a few things you can do to help limit the spread of respiratory illness over the holidays and in the coming months:

  • Get immunized​ – this is the best way to prevent serious illness
    • Everyone registered with the Get Vaccinated system will receive an invitation to book an appointment for the updated COVID-19 and influenza vaccines.
  • Stay at home if you’re feeling sick 
  • If you have any symptoms of respiratory illness and must leave your home, practice respiratory etiquette: 
    • Wear a mask in indoor public spaces 
    • Cough and sneeze into your elbow 
  • Clean your hands regularly 
  • Avoid touching your face, especially your eyes, mouth and nose 
  • If you’re sick, stay away from people at higher risk of serious illness
