再次，目前许多针对本次疫情的研究仅来自于某一个时间点，因此并不能揭示疫

Again, many current researches on this epidemic only come from a certain point in time, so it cannot reveal the long-term impact of the epidemic on people's mental health. We have not yet fully understood the long-term psychological impact of the new crown epidemic. However, some past psychological research on natural disasters and disease outbreaks (such as SARS) can help us predict the psychological impact of the new crown epidemic. These studies show that after natural disasters and disease outbreaks, although nearly two-thirds of the people can always maintain mental health, about 10% of the population still have persistent psychological problems. A retrospective study of SARS found that 44% of SARS survivors still had a post-traumatic stress response after 4 years of recovery. But we must also be optimistic to see that most people can regulate negative emotions and stress even if they are infected with an epidemic.

Third, many of the current research on this outbreak comes only from a certain point in time, so it does not reveal the long-term impact of the outbreak on people's mental health, we are not yet fully accurate understanding of the long-term psychological impact caused by the new crown outbreak. However, past psychological studies on natural disasters and disease outbreaks, such as SARS, can help us anticipate the psychological impact of the new crown outbreak. These studies show that, although nearly two-thirds of people are able to maintain mental health after natural disasters and disease outbreaks, about 10 percent of the population still have persistent psychological problems. Retrospective studies of SARS found that 44% of SARS survivors still have post-traumatic stress four years after recovery. But we should also be optimistic that most people can regulate negative emotions and stress even if they are infected with an epidemic.

Thirdly, at present, many researches on this epidemic only come from a certain time point, so they can not reveal the long-term impact of the epidemic on people's mental health. We have not fully and accurately understood the long-term psychological impact caused by the new crown epidemic. However, some past psychological studies on natural disasters and disease outbreaks (such as SARS) can help us predict the psychological impact of the new crown epidemic. These studies show that after natural disasters and disease outbreaks, although nearly two-thirds of people can always maintain mental health, about 10% of the population will still have persistent mental problems. According to the retrospective study of SARS, 44% of SARS survivors still have post-traumatic stress response 4 years after recovery. But we also want to be optimistic that most people can adjust their negative emotions and stress even if they are infected with the epidemic.
