130,000 lives may be saved if American people wear masks.
According to Science and Technology Daily news, epidemiological modeling study recently published in the British journal Nature Medicine pointed out that by February 28, 2021, the number of deaths from COVID-19 pneumonia in the United States may exceed 500,000.
The study At the same time, it is estimated that if all people wear masks, many states may avoid the worst effects of the epidemic rebound, and it is expected to save nearly 130,000 lives of these 500,000 people.
The “Nature Medicine” article stated that there is currently no approved vaccine for COVID-19 pneumonia in the United States, and there are few existing treatment options for COVID-19 pneumonia.
Therefore, non-pharmacological interventions such as wearing masks, maintaining social distancing, expanding testing, and isolating infected persons are the only means currently available to reduce the spread of the virus.
Christopher Murray, a researcher from the University of Washington in the United States, and his colleagues have conducted a state-level epidemiological analysis of the spread of new coronavirus infections in the United States and the role of non-pharmacological interventions-from the first confirmed case to September 2020 21st.
The research team used a framework of “susceptibility, exposure, infection, and recovery” and included predictions of multiple variables, including seasonal pneumonia, migration, detection rate, and use of masks per capita to evaluate the period from September 22, 2020 to September 22, 2020. During February 28, 2021, different scenarios of forced social isolation and mask use.
They found that in all scenarios, the United States is likely to continue to face the public health challenges caused by the COVID-19 pneumonia in the winter, especially densely populated states such as California, Texas, and Florida will face a large number of diagnoses, deaths and deaths. Run on medical resources.
But researchers also said that new outbreaks and a rebound of the epidemic are not inevitable. Many countries have maintained the trend of remission of COVID-19 pneumonia for a long time.
Wearing a mask is a relatively cheap and low-impact intervention to save lives in the United States.
They estimate that wearing masks for all people (assuming that 95% of people in each state insist on wearing masks in public places) may save an additional 129,574 lives by the end of February 2021, even in scenarios where the level of mask wearing is slightly lower. 95814 lives were saved.
