The legend of COVID 19 goes bankrupt: What you should know about masks, indoor transmissions and conspiracy theories



CHICAGO – Medical Executive Director for Infection Prevention and Control at the University of Chicago, Dr. Emily Landon has taken the time to dismantle some of the most popular myths about COVID-19 and pandemic, as the schools coronavirus infection continues to increase nationwide.

Inconsistent recommendations or data are not proof of conspiracy

Since the onset of the pandemic, information about COVID-19, its effects, symptoms, modes of transmission and prevention, has changed continuously, leading some to question whether it is worthwhile. Trust it or not.

It can, Landon says, and should. No one metric works in every situation, and sometimes some doctors and public health professionals use different metrics in different contexts to make a decision.

Landon says new data comes every day as science continues to explore, which can lead to disagreement, but disagreement is a normal part of the scientific process.

“We changed our guidelines because we learned something new,”

; she explained. “Changing advice will make you feel good about our progress. Disagreement is a normal part of every process and there’s no right way to deal with a new pandemic. we are all on the same boat and we should try to pass in the same direction as much as possible. “

Don’t be skeptical of masks: they work

Landon admits some of the mask guidelines may have been confusing to the public because doctors and scientists simply don’t know how important they will be to curb transmission in March. .

“Every study shows that masks reduce risk,” Landon said. “It is common practice that the mask reduces the risk. Health-care workers will become infected with COVID when they take care of the patient if the mask does not prevent infection, and the clinician’s antibody studies show that they are only with COVID slightly more than in the normal population. very close contact with patients with COVID. “

No mask is perfect, but Landon says there is growing evidence that if you become infected with COVID-19 while wearing it, you probably won’t get sick. That means masking appears to be linked to lower mortality as the pandemic progresses, according to Landon.

She also emphasized the importance of the masking regulations, pointing to a Kansas study showing that counties with the masking regulations have generally lower COVID-19 rates and lower mortality rates. Counties do not have a mask regulation.

Wearing a mask can reduce the severity of COVID-19, and proper masking is important to prevent transmission, according to Landon.

She also emphasized that the mask was absolutely safe and pointed out that everyone – from medical staff, doctors to construction workers and artists – wore them for a long time without any problems. any complications and any negative effects.

Her main point of view: Masks are safe and you must wear them to control the spread of COVID-19.

Autumn and winter will making the COVID-19 infusion worse

Doctors and public health experts have warned that COVID-19 will flare up again in the fall and winter, for a number of reasons related to the season itself, including temperature and air.

The moisture in warm air keeps COVID-19 from spreading, Landon explains. The virus gets caught in droplets of moisture in the air, getting heavier and falling faster, preventing the virus from traveling as far as possible.

In contrast, cooler, dry air and poor HVAC systems in homes and businesses create or maintain humidity. Landon says we know this through things we usually do during the winter like using extra lotion to combat dry skin or buying a humidifier to help with indoor air conditioning.

The drier air allows the COVID-19 virus to last longer, fall later, and travel farther, Landon said. That means it can be transmitted more easily via airborne transmission.

Cold weather also makes us stay indoors, in energy-efficient homes, which are able to effectively retain heat and viruses, Landon said. We therefore risk most from what Landon calls the “Three C’s: Unmasked exposure in a crowded, enclosed space.”

Studies have found that indoor ventilation in most buildings is insufficient to prevent COVID-19 transmission without a mask, Landon said. That is one of the reasons bars and restaurants are more contagious; unable to eat or drink while masking.

Therefore, it is extremely important to limit gathering indoors, from lunch in guest rooms and bookshops to larger gatherings such as eating out or having big family holidays.

“I know you miss your family and friends, and some days you might not even care if you have a COVID,” Landon said. “But you care. We all care.”
