The COVID 19 myth is shattered: knowledge about masks, indoor transmission and conspiracy theories



University of Chicago (WLS)-Dr. Emily Landon, Executive Medical Director of Infection Prevention and Control at the University of Chicago took some time to resolve some of the most common myths about COVID-19 and the pandemic, as the number of coronavirus cases in Illinois and other areas continues to increase country.

Inconsistent recommendations or data are not evidence of a conspiracy

Since the beginning of the pandemic, information about COVID-19, its effects, symptoms, modes of transmission and prevention has been changing, causing some people to question whether the information is trustworthy.

Langdon said, yes, and should. No one indicator can be effective in every situation. Sometimes doctors and public health experts use different indicators to make decisions in different contexts.

Langdon said that as science continues to learn, new data will appear every day, which may cause disagreements, but disagreements are normal in the scientific process.

She explained: “We changed the guidelines because we learned new things.”

; “The changing recommendations should make you happy with our progress. Disagreements are a normal part of every process, and there is no correct way to deal with new ones. Pandemic. Try to keep the same direction as possible.”

Don’t doubt masks: they work

Langdon fully admits that some guidelines on masks may confuse the public because doctors and scientists have no idea how important they are to contain the spread in March.

Langdon said: “Now, every study shows that masks can reduce the risk.” “Common sense says that masks reduce the risk. If masks can’t prevent infection, medical staff will get COVID when caring for patients, and medical staff have antibodies against them. Studies have shown that although the infection rate of masks is only slightly higher than that of the normal population, there is a very close connection with patients suffering from COVID.”

There is no perfect mask, but Langdon said that there is increasing evidence that if you develop COVID-19 while wearing a mask, you may not get sick. Landon said that this means that as the pandemic progresses, wearing masks also seems to be related to reducing mortality.

She also emphasized the importance of mask authorization, and pointed out that a study conducted in Kansas showed that compared with counties without mask authorization, counties with mask authorization had lower COVID-19 mortality and mortality rates.

According to Landon, wearing masks can reduce the severity of the COVID-19 disease, and consistent use of masks is essential to prevent spread.

She also emphasized that masks are absolutely safe, and pointed out that all kinds of people, from health care workers and doctors to construction workers and artists, wear masks for a long time without any complications or negative effects.

Her point is: masks are safe, and you must wear a mask to control the spread of COVID-19.

fall and winter will Worsen the spread of COVID-19

Doctors and public health experts have warned that COVID-19 will yell in autumn and winter for reasons related to the season itself, including temperature and air.

Landon explained that the moisture in the humid, warm air prevented the spread of COVID-19. The virus is enveloped by water droplets in the air, and the water droplets fall again and again faster, thus preventing the spread of the virus.

In contrast, cold air is a drier HVAC system in homes and businesses, and is not conducive to generating or maintaining humidity. Landon said, we know this, through things we usually do in winter, such as using more lotion to combat dry skin, or buying a humidifier to improve the air in the home.

The dry air keeps the COVID-19 virus hanging longer, falling later, and allowing travel, father Langdon said. This means it can be transmitted more easily via onboard transmission.

Langdon said that the cold weather also allowed us to stay in our energy-efficient and virus-proof homes. Therefore, Landon’s “three Cs: unshielded contact in a crowded enclosed space” puts us at the greatest risk.

Langdon said that the study found that most buildings have insufficient indoor ventilation to prevent the spread of COVID-19 without wearing a mask. This is one of the reasons for the higher risk of transmission in bars and restaurants; it is impossible to eat and drink with a face mask.

Therefore, limiting indoor gatherings is crucial, from lounge lunches and small book clubs to large gatherings such as dining out or large family holiday celebrations.

Langdon said, “I know you miss your family and friends, and sometimes you may not even care if you get COVID.” “But you do. We care.”
