Although the governments of the United States consider that the mandates of the lifting mask and the relaxing preventive measures, since the vaccination numbers are crawled, a new investigation of an UCLA LED team has found that such basic techniques reduce Significantly the risk of obtaining Covid-19 in research, research.
Research found that U.S. counties with greater exposures to poor air quality, historically, they saw the mortality rates of Covid-19 at higher level by 2020, with an increase of 7.6% at the Risk Covid- 19 with an increase of a 2.5 micrometers unit (μm), or PM2.5. The use of preventive measures, as well as home orders and masking, reduced the risk of Covid-19 by 15% and 8%, respectively, but did not reduce incidence increase in counties with poor air quality .
Dr. Jody Heyman, Distinguished Professor of Public Health, Public Policy and UCLA Medicine, said that the importance of improving air quality and protective measures should be included in the “lessons” that policy makers and the public have learned from the pandemic. “In the United States and globally, the burden of environmental risks is very uneven,” said Heymann, a doctor and public policy expert who serves as the director of the World Policy Analysis Center in the School of Public Health at UCLA.
There is an urgent need to reduce long-term exposure to particulate matter that are most severely exposed in the United States, and to create a healthy environment in all places where adults live and work, and all places where children they study and play.
“Health problems, in turn, seem to be connected with greater susceptibility to Covid-19 through chronic respiratory inflammation, which predisposes people to disease, greater vulnerabilities to any viral infection, including Covid;” Dr. Jianyu Rao, professor FSPH of Epidemiology and Pathology. “Air pollution could lead to overexpression of angiotensin conversion enzyme 2 (ACE2), which is the SARS-COV-2 receptor joins, which increases susceptibility to infection”.
“This is the first study to find how the association between long-term exposure to fine particulate matter and COVID-19 incidence can be affected by state prevention policies, including facemask mandates and stay home policies,” said Dr. Yifang Zhu. Study suggests a very real mitigation effect of stay home and face mask policies; facemask mandates, in fact, showed stronger protective effects toward the later course of the pandemic – exactly where we are today.”
The study is subject to some restrictions, the authors said, including that both exposure and COVID-19 incidence are measured at county/state level, not at individual level. Overall, however, these findings show that long-term exposure to fine particulate matter is a risk factor, and that the levels of exposure to in the U.S. are sufficiently high to increase the risk of COVID-19.
“Although 43% of the US population has been vaccinated and many of the states are opening, those who are not yet vaccinated will be at a high risk of infection by emerging COVID-19 variants,” said Dr. Lina Mu. “We should still practice face covering and social distancing to protect themselves from infection before they are fully vaccinated.”
