The United States has taken another stepdark ape in their struggle against the Covid-19 pandemic : 1 in 500 Americans have died from coronavirus since the first reported infection in the country. As of Tuesday evening, 663,913 people in United States died from Covid-19, according to Data from Johns Hopkins University . According to the US Census Bureau , the US population in April 2020 was 331.4 million. It's a sobering toll as US hospitals struggle to keep up with the volume of patients and growing numbers of children. are struggling with the virus. In hopes of managing the spread and preventing more unnecessary deaths, authorities are puttingnt implement work place vaccination and school masking mandates. Covid-19 vaccines for young children could be licensed this fall, according to Fauci They are battling a strong upward trend in cases and deaths: the United States reports a more than 30% increase in the average number of daily cases and a near-tripling of average daily deaths over the course of last month, according to data from US Centers for Control and disease prevention. But with only 54% of the population fully vaccinated, the rate of people initiating vaccinations each day has declined over the past month. Health experts hailed vaccination as the best source of protection against the virus, noting that the majority of people hospitalized and killed by Covid-19 are unvaccinated . In Pennsylvania, January 1 to 7 September, 97% of Covid-19 deaths in the state were unvaccinated people, Pennsylvania's acting health secretary said on Tuesday Day Another strong layer of protection, experts say, is masking. The CDC recommends that people - even those fully vaccinated - wear masks indoors in areas with high or high community transmission. More than 99% of the population lives in a county with one. In Ohio, children's hospitals are inundated with Covid-19 and respiratory cases, Gov. Mike DeWine said, urging schools to issue mask warrants as the state legislature him. said she would cancel any warrant he issued. Reasonable people can disagree on a lot of things, but we canWe all agree that we need to keep our kids in class so they don't fall behind and their parents go to work and not take time off to watch their kids at home, said DeWine. The combination of masks and vaccinations is the way to keep kids in school, Dr Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, told CNN on Tuesday. children of vaccinated people and everyone wearing a mask, you can get a situation where the kids will be relatively safe in school, Fauci told CNN's Jake. Tapper. A memorial for those who died of Covid-19 is on view on the National Mall on September 22, 2020 in Washington, DC. Fighting over vaccine warrants In an effort to manage the spread of the virus, many officials and experts have promoted immunization warrants - but others oppose such measures. New York has issued a target order in August requiring all healthcare workers to be vaccinated against Covid-19 before September 27. But on Monday, 17 healthcare professionalsCatholics and Baptists have filed a federal lawsuit seeking to prevent the state from enforcing the warrant, claiming it opposes obtaining the vaccine on religious grounds. On Tuesday, a federal judge issued a restraining order order temporarily suspending New York State from the application of its immunization mandate if healthcare workers demand a religious exemption. It may take 'many, many ' additional vaccine mandates to end Covid-19 pandemic, according to Fauci Because the warrant does not require healthcare workers to receive their first dose of the vaccine by September 27, the judge's order says that the temporary restraining order, in practice, does not come into effect until that date. A hearing is scheduled for September 28. Following the ruling, New York Governor Kathy Hochul L Hazel Crampton-Hays' press secretary said in a cosaid the governor was considering all legal options. Governor Hochul is doing everything in her power to protect New Yorkers and combat the Delta variant by increasing vaccination rates across the state, Crampton-Hays. In Los Angeles, despite a warrant according to which all city employees must be vaccinated against the virus, nearly a quarter of law enforcement is asking for a waiver, according to the office of mayor Eric Garcetti. Those who are not vaccinated will be required to show evidence of weekly testing and a negative COVID result if they regularly report to work. By November 1, Nevada workers who serve vulnerable populations must show proof of vaccination under a new emergency rule passed Tuesday. New hires must have at least one dose before their start date and must follow the vaccination schedule required to remain in use.Workers are allowed to request a medical or religious exemption. Recall meeting will not be a slam dunk US Food and Drug Administration (FDA) Friday meet to discuss if most Americans need a booster of their Covid-19 vaccine. Unlik The other meetings to discuss the vaccine, this one, along with Pfizer's demands to allow a third dose for most people, will not be a slam dunk. It will be a lot more complicated than in December. said Dr William Schaffner, infectious disease specialist at Vanderbilt University. The FDA committee was quick to recommend the clearance of vaccines made by Pfizer and rival Moderna last December. When the FDA 's Advisory Committee on Vaccines and Related Biologics meets on Friday , he will be presente with dueling data, some suggesting there is a need for callbacks, but other data elements suggesting there is no such need. 3 states have fully vaccinated more than 2/3 of residents. Elsewhere, hospitals are inundated with patients Unvaccinated Covid-19 Three separate articles published last week in the CDC's Weekly Morbidity and Mortality Report suggest we don 't need boosters. On the other hand, a Israeli study found that over time, the power of vaccines to prevent people from contracting Covid-19 patients worsened. Looking at illnesses in the second half of July, this study found that those who had received their second dose of Pfizer vaccine in March were 70% more protected against serious illness than those who received the second dose in January. next week. Although she does not say directly if this date would be met, the diCDC rector Rochelle Walensky said on Tuesday she was optimistic about the timing for the administration of the doses. If the recall is approved, experts will still have to wait and see what protection is added by the third dose. Hopefully this will support us for an extended period of time, but I don't know that right now, Fauci said. We're just going to have to do the boost and then follow people long enough to determine how durable this protection is.
