#FireAdrianDix WORKED!

They would have more seats if Eby fired Dix and Dr. #Disinformation on masks,covid aerosol spread, minimizer of Covid & LongCovid, Bonnie Henry years ago

Josie Osborne is minister of health.

Call/phone your MLAs to get her to put #N95MaskMandates in health care

BC's #MaskMandate now includes Home Care too!

Good. 20 min+ of HCW in close contact with patient & most now are #FreedomToInfect Maskless = infect patients w/ CV/Flu/Measles

BUT should be #N95MaskMandates Far better than surgical

Mask mandate returns in health authority-operated facilities JANUARY 9, 2025 NEWS On January 6, 2025, the BC Ministry of Health announced the return of mandatory medical masks in facilities operated or contracted by provincial health authorities. These facilities include hospitals, long-term care and assisted living facilities, outpatient clinics, and ambulatory care settings. Due to an increase in respiratory illnesses such as influenza and RSV throughout the province, health care workers, visitors, contractors, and volunteers in these settings must wear medical masks. This will curb the spread of these illnesses and protect against preventable illness, keeping health care workers, patients, and facility residents safe. Masks will be required in patient care areas, which are any area in a health facility where patients, clients, or residents are actively receiving care. These include: Waiting rooms including emergency rooms Home and community care locations (including a client’s home) Any location where emergency health services are being provided (e.g. - ambulances, air ambulances) To learn more about the requirements, including exemptions, please visit the BC government website(link is external). Masking is currently not required in community clinic settings. The mandate is expected to remain until Spring 2025. If you have questions regarding the mandate, please connect with your local health authority .

Not content with refusing to protect HCW & patients with #N95MaskMandates in healthcare for #Covid19, BC's Do More Harm PHO Dr. Bonnie Henry continues here #FreedomToInfect spree.

Not just covid, Measles too.

Gets rid of Measles vaccine requirement for schools

healthline Health Conditions v Discover v Plan v Connect v In contrast, diseases that are transmitted through bodily fluids, such as Ebola or HIV, aren't as easy to contract or transmit. This is because you need to come into contact with infected blood, saliva, or other bodily fluids to contract them. https://www.healthline.com/health/r-naught-reproduction-number Airborne illnesses tend to have a higher Ro value than those spread through direct contact. What conditions are measured by RO? Ro can be used to measure any contagious disease that may spread Battling infectious diseases in the 20th century the impact of vaccines The number of measles infected people, measured over 70-some years and across all 50 states and the District of Columbia, generally declined after vaccines were introduced. The heat maps below show number of cases per 100,000 people. Battling Infectious Diseases in the 20th "In a susceptible population, 90% of people exposed to someone with measles will come down with it. You can be across a gymnasium, and if you are not immune to measles, and there's someone in that gymnasium with measles. Hospitalization. About 1 in 5 unvaccinated people in the U.S. who get measles is hospitalized. Death. Nearly 1 to 3 of every 1,000 children who become infected with measles will die from respiratory and neurologic complications.”

Wearing N95 Masks. 0.11



 Wearing Surgical Masks. 1.51 These results, suggest that the risk of airborne transmission can be significantly reduced by wearing N95 masks inside the ward. However, it is impossible for all patients to wear N95 masks in the hospital. Therefore, maintaining good ventilation as much as possible is the feasible alternative measure to prevent airborne transmission in the ward.
