CDC: Act Now Against Infectious COVIDB.1.1.7

The Centers for Disease Control and Prevention (CDC) requires the general public, elected officials, and healthcare professionals to take immediate action against the highly infectious coronavirus disease 2019 (COVID-19). I want to tell you. England. Without that response, B.1.1.7 will be the dominant stock of COVID-19 in the United States by March. At the time of this writing, there are 76 known cases of B.1.1.7 in the United States. The COVID-19 vaccine should be effective against B.1.1.7, but that is not important. More infections mean more hospitalizations and higher mortality, all of which put more strain on the already unmanageable healthcare system.

“The experience in the UK and the B.1.1.7 model presented in this report show the effect of more contagious mutations on the number of cases in the population,” a study published in the CDC said. .. Weekly morbidity and mortality reports.. “Increased infectivity of this variant requires the implementation of a tighter combination of vaccination and mitigation measures (eg distance, masking, hand hygiene) to control the spread of SARS-CoV-2. These measures will be more effective if started early rather than later to delay the initial spread of the B.1.1.7 variant. “

President-elect Joe Biden wants to distribute 100 million doses of COVID-19 vaccine in the first 100 days. Research says they will be needed. “Increased infectivity may also require higher than expected vaccination rates to achieve the same level of disease control to protect the public compared to less infectious mutants. It means, “says the study.

The CDC is leading a collaborative effort involving state, academia, industry, and local health authorities to enhance COVID-19 genome surveillance throughout the United States. “Multiple evidence shows that B.1.1.7 is more efficiently infected than other SARS-CoV-2 mutants prevalent in the United Kingdom,” the study said. I will. “In the UK region, where the proportion of B.1.1.7 sequences is high, epidemic growth was faster than in other regions, diagnosed as SGTF.[S-gene target failure] It increased faster than non-SGTF diagnoses in the same region, with a higher proportion of contacts infected with B.1.1.7-infected index patients than index patients infected with other variants. “

CDC investigators will look at multiple models of how B.1.1.7 spreads. One of the models assumes that one million COVID-19 vaccines will be distributed daily from January 1, 2021. The model also shows that 95% herd immunity was achieved 14 days after the second vaccination.Obviously, this is not happening (whether or not herd immunity to COVID-19 can be achieved is a question debate), But researchers wanted to see how threatening B.1.1.7 would pose if near-universal immunity to infection was assumed.

“In this model, the prevalence of B.1.1.7 is initially low, but because it is more infectious than current variants, it showed rapid growth in early 2021 and the dominant variant in March. “It will be,” the study said. “Whether the transmission of the current variant is increasing in January (initial Rt = 1.1) or slowly decreasing (initial Rt = 0.9), B.1.1.7 has a significant transmission trajectory. It drives a new phase of rapid change and exponential growth. Vaccination to prevent infection does not change the trajectory of the early epidemic and the B.1.1.7 epidemic still occurs.

However, in this model, the transmission of B.1.1.7 is significantly reduced after becoming the dominant strain.

“The effect of vaccination on short-term infection reduction was greatest in scenarios where infection was already reduced (initial Rt = 0.9),” the study said. “More to achieve higher population-level immunity through continuous vaccination, with early efforts to limit the spread of B.1.1.7 variants, such as universal and enhanced compliance with public health mitigation strategies. Time will be possible. “

CDC findings occur when COVID-19 goes out of control due to a runaway. The hospital is full. Infection prevention physicians and other healthcare professionals work 24 hours a day. They are exhausted. Dr. Rochelle Warrensky, MD, who heads the Biden administration’s CDC, warns that the death toll in the United States could reach 500,000 by mid-February. According to Johns Hopkins University, 1723 people died of COVID-19 in the United States yesterday, and 174,513 newly confirmed cases were seen in the United States.
