Covid-19: I have experienced many real nightmares
Heather Elizabeth Brown is one of more than 90million covid-19 infected people in the United States. More than two years after the diagnosis of covid-19 infection, Brown's body and mind are still suffering from long-term effects. She said that recalling her experiences over the past two years, she seemed to have a real and painful nightmare.
Heather Elizabeth brown, a covid-19 patient: I want to live a normal life. I don't have to think about how I was infected with covid-19 from time to time, how I fought the virus, or the pain I suffered.
In April 2020, Brown was confirmed to be infected with novel coronavirus. Forty eight hours after the diagnosis, brown fell into a coma. For the next 31 days, she had to rely on a ventilator to maintain her life.
New coronavirus patient Heather Elizabeth Brown: novel coronavirus has taken away too many things from me. I have too many real nightmares. I wake up, but I can't talk or walk. The left side of my whole body is very weak, and I can't even press the button to call the nurse.
After leaving the hospital, Brown has not fully recovered. For more than two years, her body and mind are still suffering. Due to the weakness of Brown's muscles caused by lying in bed with a ventilator for a long time, she also needs long-term training to recover her physical function.
New coronavirus patient Heather Elizabeth Brown: I never thought I would face such a severe health challenge in my thirties and need to learn to walk again.
The United States faces more serious challenges as the epidemic worsens and the prevention and control is lax
Recently, new subtypes ba.5 and ba The spread has accelerated in the United States, setting off a new wave of infection peak. At present, the cumulative number of confirmed cases of covid-19 in the United States has exceeded 90million, and more than half of the population lives in the high-risk areas designated by the Centers for Disease Control and prevention.
U.S. experts and media have said that due to lax prevention and control measures, the United States is afraid to face more severe challenges in the coming months.
Recent data from the CDC showed that since mid May, ba.5 and ba The number of infection cases caused by these two new subtypes continues to rise. According to its data released on the 14th, at present, 55% of the population in the United States, that is, more than half of the population live in high-risk areas of the COVID-19. The previous week, the figure was 32%. In addition, 30% of Americans live in medium risk areas.
In addition, as of the week of the 17th, several regions, including Suffolk County, New York, San Diego County, California, and Dallas County, Texas, rose from medium-risk areas to high-risk areas.
Several U.S. health officials said that the actual number of confirmed cases across the United States may be greatly underestimated, given that many Americans currently test at home or do not test at all. Topol, a geneticist at the Scripps Institute in the United States, believes that the real number of confirmed cases in the United States may be as high as 1million, which is very worrying.
At the same time, the number of hospitalizations in covid-19 continues to rise. Wallensky, director of the Centers for Disease Control and prevention in the United States, said recently that since the beginning of May, the average daily increase in the number of hospitalizations for covid-19 in the United States has doubled. Other data showed that the number of hospitalizations of covid-19 in most parts of the United States was increasing, which was many times more serious than the same period last year, and the pressure on hospitals increased sharply.
Lax prevention and control measures face great challenges in epidemic prevention and control in the United States
The Washington Post previously reported that in ba At the time of the attack, many epidemic prevention and control measures in the United States had already been canceled, flight travel had basically returned to the pre epidemic level, and most of the public had given up wearing masks, maintaining social distance and other measures, which gave the virus an opportunity.
Ziad Ali, an associate professor at Washington University School of medicine in St. Louis, said there were no public health measures to prevent covid-19 infection at all. "The risk is there, obviously, but we have relaxed our vigilance."
