Clinical trends among U.S. adults hospitalized with COVID-19, March to December 2020: a cross-sectional study. Omicron is super infectious, and about 20% of people in the United States over the age of 5 as well as all children under 5 remain unvaccinated. The average death rate among Americans over age 65 who contract the flu has ranged between 1 in 75 and 1 in 160 in recent years, according to the C.D.C. These proportions are lower compared with 47.3% of White persons who received a primary series and 54.5% of eligible adults who received a booster dose. Relative to the Delta-predominant period, Black adults accounted for a larger proportion of unvaccinated adults during the Omicron-predominant period, and age-adjusted hospitalization rates for Black adults increased to the highest rate among all racial and ethnic groups for any week during the pandemic. The TND is designed to better control for bias related to health care-seeking behavior31,32. We, therefore, were unable to assess whether maternal infection provided some protection to their infants. We were not able to evaluate more detailed measures of relative clinical severity in hospitalised patients (such as intensive care unit admittance), but our finding that estimated severity reductions comparing omicron with delta are larger for more severe endpoints (death and hospital admission versus hospital attendance) agrees with observations that the proportion of hospitalised COVID-19 patients requiring intensive care or mechanical ventilation (or both) has been substantially lower during the omicron wave in England than the preceding delta wave. ***** An additional 172 (3.4%, 95% CI=2.7%4.2%) adults were partially vaccinated, 69 (0.9%, 95% CI=0.61.2) received a primary vaccination series <14 days before a positive for SARS-CoV-2 test result, and 186 (4.1%) had unknown vaccination status; these groups are not further described in this analysis. However, these Omicron impacts have been mostly observed in countries with high vaccination rates in the Region: the comparatively lower rate of hospitalizations and deaths so far is in large part thanks to vaccination, particularly of vulnerable groups. Andrews, N. et al. The state has administered 3.2 million vaccine doses since Dec. 1 alone, but lagging rates between full vaccination and first doses for adults especially (82.6% vs. 95%) are becoming a point of . Vaccinated patients during the Delta wave were 37% (over with two doses), while during the Omicron wave they were 57%. New federal data shows adults who received the updated shots cut their risk of being hospitalized with . Dis. China informed the WHO about the case, which involves a 53-year-old woman, on Feb 24. "The subpopulations with the highest risk should be considered a priority for COVID-19 therapeutics and further booster doses.". All authors reviewed the manuscript. Health and Human Services. T.R. Omicron data in UK is 'enormously worrying,' immunologist says "In the last two weeks, no fewer than 80% of admissions were below the age of 50 years. As a result, the number of total hospitalizations exceeds the sum of unvaccinated adults, adults who received a primary series without a booster or additional dose, and adults who received a primary series with a booster or additional dose. wrote the initial manuscript. The researchers used the QCovid risk model to estimate hazard ratios (HRs) for clinical risk factors. Vaccination status is based on state immunization information system data. There was no link between risk of COVID-19 death and race, except for Indian patients, who were at slightly higher risk than their White peers. *** An additional 172 (3.4%, 95% CI = 2.7%4.2%) adults were partially vaccinated, 69 (0.9%, 95% CI=0.61.2) received a primary vaccination series <14 days before receiving a positive SARS-CoV-2 test result, and 186 (4.1%) had unknown vaccination status; these groups are not further described in this analysis. What are the implications for public health practice? Percentages presented for demographic characteristics are weighted column percentages. These findings are consistent with estimates of booster effectiveness against symptomatic Omicron infection using healthcare ascertainment. Accessed March 10, 2022. PubMed Shimabukuro, T. T. et al. Adults with a positive result whose SARS-CoV-2 test date was 14 days after the first dose of a 2-dose series but <14 days after receipt of the second dose were considered partially vaccinated. With the emergence of the SARS-CoV-2 Omicron variant in late 2021, Canadian public health case/contact testing was scaled back due to high infection rates with milder symptoms in a highly vaccinated population. 383, 26032615 (2020). Most hospitalized children were unvaccinated, and nearly one in three were Black.

Ayoub, Laith J. Abu-Raddad, Nature Communications References to non-CDC sites on the Internet are In the present study, the mothers of only 32% of infants in the cohort received at least 2 doses during pregnancy. Still, even with a smaller percentage of people getting severely ill during the Omicron wave, a large number of cases over a short time can lead to a spike in people being hospitalized or admitted .

IMV status was missing in 1.4% (weighted) of hospitalizations; these hospitalizations are otherwise included elsewhere in the analysis. This conversion might result in character translation or format errors in the HTML version. N. Engl. Vaccinated patients were older (68 vs. 57 years), and 62% had at least one comorbidity Admission to the ICU was 20%, and the mortality rate at 30 days was 14%. Corresponding author: Christopher A. Taylor, iyq3@cdc.gov. To ensure stability and reliability of rates by vaccination status, data are presented beginning 14 days after at least 5% of the age group-specific population of the COVID-NET surveillance catchment area has received an additional or booster dose. Vaccination status is not available for Iowa and cases from Iowa are excluded from analyses that examined vaccination status. Risk factors for severe COVID-19 in children. Includes current treatment or recent diagnosis of an immunosuppressive condition or use of an immunosuppressive therapy during the preceding 12 months. The TND analyses avoid this bias by limiting the analysis to infants who were tested for SARS-CoV-2. Adults whose vaccination status had not yet been verified using the immunization information system data were considered to have unknown vaccination status and were included in total proportions but not stratified by vaccination status. Late last year, as Omicron was spreading fast in the US, hospitalization rates per 100,000 rose sharply among unvaccinated adults, while rates in those who were fully vaccinated remained low. and B.F. P.R. We conducted a descriptive analysis of the study population and calculated crude rates of SARS-CoV-2 infection and hospitalization by maternal vaccination status. Compared with the Delta-predominant period, the proportion of unvaccinated hospitalized Black adults increased during the Omicron-predominant period. As with previous variants, being vaccinated greatly protects you from severe disease with omicron. PubMed Central We observed a similar pattern in vaccine effectiveness by trimester during the Omicron dominant period, however, estimates of vaccine effectiveness by trimester were imprecise and much lower than during the Delta period (Table3). Analyses were conducted using SAS statistical software survey procedures (version 9.4; SAS Institute). Clinical information was abstracted for 5,681 adults with COVID-19associated hospitalization during July 1, 2021January 31, 2022 (Table). COVID-19 vaccines have demonstrated both high efficacy in clinical trials and high real-world effectiveness, especially against the original and Delta variant of the virus6,7,8,9,10. All analyses were conducted using SAS software, v9.4. Nature. N. Engl. E. & Klein, N. P. Effectiveness of vaccination during pregnancy to prevent infant pertussis. Members receive almost all their medical care at KPNC-owned facilities, including clinics, hospitals, pharmacies, and laboratories. However, we have no reason to expect a strong association between the absence of NHS number and SARS-CoV-2 variant.

COVID-NET conducts population-based surveillance for laboratory-confirmed COVID-19associated hospitalizations in 99 counties across 14 states. COVID-19associated hospitalizations are those occurring among residents of a predefined surveillance catchment area who have a positive real-time reverse transcriptionpolymerase chain reaction (RT-PCR) or rapid antigen detection test result for SARS-CoV-2 during hospitalization or the 14 days preceding admission. Includes current treatment or recent diagnosis within the previous 12 months of an immunosuppressive condition or use of an immunosuppressive therapy. Two recent papers claim there are no differences between surgical masks and respirators for preventing the spread of respiratory diseases like COVID-19 and flu, but the articles are deeply flawed. Article The funders played no direct role in the study. 1.04-1.49) after adjusting for age, sex, and vaccine characteristics. The outcomes were the infants first positive nasal/throat swab for SARS-CoV-2 by PCR, and the first COVID-19-related hospitalization, occurring during the first 6 months of life and recorded in the electronic health record. Selected counties in California, Colorado, Connecticut, Georgia, Iowa, Maryland, Michigan, Minnesota, New Mexico, New York, Ohio, Oregon, Tennessee, and Utah (https://www.cdc.gov/mmwr/volumes/69/wr/mm6915e3.htm). supervised chart reviews. Spontaneous abortion following COVID-19 vaccination during pregnancy. 384, 21872201 (2021). 9-14 As of October 2022, 68% of the US population has completed primary series vaccination. Vaccine 35, 72977301 (2017). Nature Communications thanks Annette Regan, Olof Stephansson and the other, anonymous, reviewer(s) for their contribution to the peer review of this work. The study did not adjust for maternal SARS-CoV-2 infections during pregnancy due to the inability of capturing home testing results. Our additional supplemental analysis suggests that pregnant persons who received at least one vaccine dose before pregnancy should complete their vaccination series during pregnancy to provide protection to their children during the first 6 months of life. Additional COVID-NET methods for determining vaccination status have been described previously. As of December 25, the rate among unvaccinated people was 78 per 100,000, compared to 4 per 100,000 among fully vaccinated people, the CDC reported. Safety and efficacy of single-dose Ad26.COV2.S vaccine against Covid-19. of Omicron-infected patients with a high rate of vaccination in China.

Pediatrics. However, protection estimates greater than 90% might be too high if individuals with a previous infection were more likely than those without one to come forward for a test for reasons other than suspicion of COVID-19.
