World AIDS Day is on Dec. 1.
Since 2004, global deaths have been in decline due to greater access to diagnostics, treatment & prevention.
This hard-won progress is now at risk due to major cuts to global public health.
We can't afford to go backward.

More data outlining how COVID vaccines reduce the risk of hospitalizations & death, especially among those aged 65 and older.
This aligns nicely with recommendations from Canada's National Advisory Committee on Immunization. 🇨🇦

Someone in Germany is shedding poliovirus - a crippling disease which should be eradicated.
This is another stark reminder of the risks we face when global vaccination coverage slips.

Exciting to see a new compound showing promise against malaria.
As drug resistance grows, mosquito ranges expand & public health resources remain limited, the need for new treatments has never been greater.

Canada has lost its measles elimination status...a sad milestone.
Now is the time to double down on lowering barriers to routine childhood immunizations and ensuring Canadians have access to credible, science-based information.

Influenza cases are climbing in Canada.
Flu shots are widely available, and can help lower the chance of infection and hospitalization.
Below are this year’s flu trends (arrow) vs. the past three years.

Antimicrobial resistance kills over a million people yearly.
I joined colleagues before the House of Commons Committee on Science & Research to discuss how Canada can help fight this threat.
Local action matters but global coordination is essential. 🇨🇦

@paulsaxmd.bsky.social knocks it out of the park with his analysis on 2 new COVID vaccine studies.
If you want data, nuance & common sense, have a read.
Key takeaway: COVID vaccine makes sense for those at greatest risk for severe infection (eg. elderly).

Attending the Global Conference on Biological Threat Reduction in Geneva with colleagues from around the world to strengthen strategies against infectious disease outbreaks, whether natural, accidental, or deliberate. Great to see Canada taking a leadership role in this sphere.🇨🇦

The southern hemisphere offers an imperfect but useful preview of our flu season, and they had a tough one: High case numbers & lower vaccine uptake among those most at risk.
Flu shots in Ontario for high risk folks are available now & to the general public starting next week.

A locally acquired case of Chikungunya virus in New York State? This is a first.
Chikungunya is a mosquito-transmitted infection that can cause impressive (and sometimes lasting) joint pain and inflammation.

New 🇨🇦 data in @cmaj.ca (from BC) showing relatively strong population-level measles immunity.
Outbreaks are likely to be more focal in under-vaccinated groups.
Some age cohorts are still <90% immune, so maintaining high vaccine coverage remains key.

Our team is developing portable digital microscopes that harness AI to automatically detect parasitic infections.
This shows great potential to help public health programs expand access to affordable disease screening in low-resource settings.

Although the genetic fingerprint has shifted a bit, there is absolutely nothing new from a clinical, diagnostic, therapeutic, or preventive perspective.
Are we really going to do this every time the virus mutates, which it will continue to do frequently & indefinitely?

RMSF has also been found in dogs in southern ON & in a person in QC who may have caught it in ON.

COVID cases are beginning to rise in Canada. While rates remain lower than at this time in recent years, they are still trending upward.
Health Canada has also just approved a new COVID vaccine for the fall rollout, targeting LP.8.1 (a sublineage of Omicron).
