Provision of safe water in the United States is vital to protecting public health (1). Public agencies U.S. states and territories* report information on waterborne disease outbreaks CDC through National Outbreak Reporting System (NORS) (https://www.cdc.gov/healthywater/surveillance/index.html). During 2013-2014, 42 drinking water-associated† were reported, accounting for at least 1,006 cases illness, 124 hospitalizations, 13 deaths. Legionella was associated with 57% these all Sixty-nine...
Although COVID-19 generally results in milder disease children and adolescents than adults, severe illness from can occur might require hospitalization intensive care unit (ICU) support (1-3). It is not known whether the B.1.617.2 (Delta) variant,* which has been predominant variant of SARS-CoV-2 (the virus that causes COVID-19) United States since late June 2021,† different clinical outcomes compared with variants circulated earlier. To assess trends among adolescents, CDC analyzed new...
Abstract Background The evidence base for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is nascent. We sought to characterize SARS-CoV-2 transmission within US households and estimate the household secondary infection rate (SIR) inform strategies reduce transmission. Methods recruited patients with laboratory-confirmed their contacts in Utah Wisconsin during 22 March 2020–25 April 2020. interviewed all obtain demographics medical histories. At initial visit, 14 days later,...
By May 2021, 69%, 45%, and 26% of adults aged ≥65, 50–64, 18–49 years were vaccinated. From November–December 2020 to April–May the rate ratios COVID-19 incidence, emergency department visits, hospital admissions, deaths among persons ≥65 declined 40%, 59%, 65%, 66%, respectively.
To better understand severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) shedding and infectivity, we estimated SARS-CoV-2 RNA duration, described participant characteristics associated with the first negative rRT-PCR test (resolution), determined if replication-competent viruses was recoverable ≥10 days after symptom onset.We collected serial nasopharyngeal specimens from 109 individuals rRT-PCR-confirmed COVID-19 in Utah Wisconsin. We calculated viral resolution probability using...
Abstract Background Detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has principally been performed through the use real-time reverse-transcription polymerase chain reaction testing. Results such tests can be reported as cycle threshold (Ct) values, which may provide semi-quantitative or indirect measurements viral load. Previous reports have examined temporal trends in Ct values over course a SARS-CoV-2 infection. Methods Using testing data collected...
Limited data exist on severe acute respiratory syndrome coronavirus 2 in children. We described infection rates and symptom profiles among pediatric household contacts of individuals with disease 2019.We enrolled 2019 their contacts, assessed daily symptoms prospectively for 14 days, obtained specimens real-time reverse transcription polymerase chain reaction serology testing. Among (<18 years), we transmission, the risk factors infection, calculated positive negative predictive values....
In the USA, COVID-19 vaccines became available in mid-December, 2020, with adults aged 65 years and older among first groups prioritised for vaccination. We estimated national-level impact of initial phases US vaccination programme on cases, emergency department visits, hospital admissions, deaths older.We analysed population-based data reported to federal agencies 50 during period Nov 1, April 10, 2021. calculated relative change incidence age compared a younger reference group...
Nursing home residents have experienced disproportionally high levels of COVID-19-associated morbidity and mortality were prioritized for early COVID-19 vaccination (1). Following reported declines in vaccine-induced immunity after primary series vaccination, defined as receipt 2 doses an mRNA vaccine (BNT162b2 [Pfizer-BioNTech] or mRNA-1273 [Moderna]) 1 dose Ad26.COV2 (Johnson & Johnson [Janssen]) (2), CDC recommended that all persons aged ≥12 years receive a booster dose.* Moderately to...
The Republic of Haiti is one only several countries in the Western Hemisphere which canine rabies still endemic. Estimation methods have predicted that 130 human deaths occur per year, yet existing surveillance mechanisms detected few these cases. Likewise, capacity has had limited capacity, detecting two rabid dogs on average. In 2013, initiated a community-based animal program comprised components: active community bite investigation and passive investigation. From January 2013 -December...
Improved understanding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spectrum disease is essential for clinical and public health interventions. There are limited data on mild or asymptomatic infections, but recognition these individuals key as they contribute to viral transmission. We describe the symptom profiles from with SARS-CoV-2 infection.From 22 March April 2020 in Wisconsin Utah, we enrolled prospectively observed 198 household contacts exposed SARS-CoV-2....
Health care personnel (HCP) are recommended to receive annual vaccination against influenza reduce influenza-related morbidity and mortality. Every year, acute hospitals report receipt of among HCP CDC's National Healthcare Safety Network (NHSN). This analysis used NHSN data describe changes in coverage before during the COVID-19 pandemic. Influenza increased prepandemic period from 88.6% 2017-18 90.7% 2019-20. During pandemic, percentage vaccinated decreased 85.9% 2020-21 81.1% 2022-23....
To protect both patients and staff, healthcare personnel (HCP) were among the first groups in United States recommended to receive COVID-19 vaccine. We analyzed data reported U.S. Department of Health Human Services (HHS) Unified Hospital Data Surveillance System on vaccination coverage hospital-based HCP. After vaccine introduction December 2020, rose steadily through April 2021, but rate uptake has since slowed; as September 15, 3,357,348 HCP 2,086 hospitals included this analysis, 70.0%...
Abstract Objective The incidence of infections from extended-spectrum β-lactamase (ESBL)–producing Enterobacterales (ESBL-E) is increasing in the United States. We describe epidemiology ESBL-E at 5 Emerging Infections Program (EIP) sites. Methods During October–December 2017, we piloted active laboratory- and population-based (New York, New Mexico, Tennessee) or sentinel (Colorado, Georgia) surveillance. An incident case was first isolation normally sterile body sites urine Escherichia coli...
Persons receiving maintenance dialysis are at increased risk for SARS-CoV-2 infection and its severe outcomes, including death. However, rates of COVID-19-related deaths in this population not well described. Since November 2020, CDC's National Healthcare Safety Network (NHSN) has collected weekly data monitoring incidence infections (defined as a positive test result) the death patient who had fully recovered from infection) among patients. This analysis used NHSN facility COVID-19 reported...
Nursing home residents have been disproportionately affected by the COVID-19 pandemic; their age, comorbidities, and exposure to a congregate setting has placed them at high risk for both infection severe COVID-19-associated outcomes, including death (1). Receipt of primary mRNA vaccination series (2) monovalent booster doses (3) demonstrated be effective in reducing COVID-19-related morbidity mortality this population. Beginning October 2022, National Healthcare Safety Network (NHSN)...
Abstract Background CDC recommends that residents and healthcare personnel (HCP) in nursing homes be up to date with COVID-19 vaccinations protect residents, who are at increased risk for severe COVID-19. vaccination coverage is often lower rural versus urban populations; it unclear if this applies HCPs homes. We assessed the association of urbanicity up-to-date HCP U.S. Methods conducted a cross-sectional study 14,304 reporting CDC’s National Healthcare Safety Network (NHSN) week ending...
We examined the association between influenza vaccination policies at acute care hospitals and coverage among healthcare personnel for 2021-22 season. Mandatory masking unvaccinated were associated with increased odds of vaccination. Hospital employees had higher than licensed independent practitioners.
The Advisory Committee on Immunization Practices recommends that health care personnel (HCP) receive an annual influenza vaccine and everyone aged ≥6 months stay up to date with recommended COVID-19 vaccination. Health facilities report vaccination of HCP against CDC's National Healthcare Safety Network (NHSN). During January-June 2023, NHSN defined up-to-date as receipt a bivalent mRNA dose or completion primary series within the preceding 2 months. This analysis describes coverage among...
Nursing home residents are at increased risk for developing severe COVID-19.Nursing homes report weekly facilitylevel data on SARS-CoV-2 infections, COVID-19-associated hospitalizations, and COVID-19 vaccination coverage among to CDC's National Healthcare Safety Network.This analysis describes rates of incident infection, hospitalization, during October 16, 2023-February 11, 2024.Weekly infection ranged from 61.4 133.8 per 10,000 nursing residents.The percentage facilities reporting one or...
Exposures to contaminated water can lead waterborne disease outbreaks associated with various sources, including many that are classified and reported separately as drinking or recreational water. Waterborne also involve a variety of other exposures (e.g., consuming directly from backcountry wilderness streams, inhaling aerosols cooling towers ornamental fountains). Additionally, might be epidemiologically linked multiple sources may not have specific source implicated.
Giardia duodenalis is the most common intestinal parasite of humans in USA, but risk factors for sporadic (non-outbreak) giardiasis are not well described. The Centers Disease Control and Prevention Colorado Minnesota public health departments conducted a case-control study to assess USA. Cases (N = 199) were patients with non-outbreak-associated laboratory-confirmed infection Minnesota, controls 381) matched by age site. Identified included international travel (aOR 13.9; 95% CI 4.9-39.8),...
