The following guidance is directed to administrators of schools from kindergarten to grade 12 (K-12) and local public health authorities (PHAs) in jurisdictions where these schools exist. The guidance is not prescriptive in nature, rather, it supports administrators and PHA's to consider potential risks and mitigation strategies associated with the resumption of in-school classes during the COVID-19 pandemic.

The 2020-2021 School Learning Modalities dataset provides weekly estimates of school learning modality (including in-person, remote, or hybrid learning) for U.S. K-12 public and independent charter school districts for the 2020-2021 school year, from August 2020 – June 2021.

These data were modeled using multiple sources of input data (see below) to infer the most likely learning modality of a school district for a given week. These data should be considered district-level estimates and may not always reflect true learning modality, particularly for districts in which data are unavailable. If a district reports multiple modality types within the same week, the modality offered for the majority of those days is reflected in the weekly estimate. All school district metadata are sourced from the https://nces.ed.gov/ccd/files.asp#Fiscal:2,LevelId:5,SchoolYearId:35,Page:1">National Center for Educational Statistics (NCES) for 2020-2021.

School learning modality types are defined as follows:

• In-Person: All schools within the district offer face-to-face instruction 5 days per week to all students at all available grade levels.
• Remote: Schools within the district do not offer face-to-face instruction; all learning is conducted online/remotely to all students at all available grade levels.
• Hybrid: Schools within the district offer a combination of in-person and remote learning; face-to-face instruction is offered less than 5 days per week, or only to a subset of students.

Data Information

• School learning modality data provided here are model estimates using combined input data and are not guaranteed to be 100% accurate. This learning modality dataset was generated by combining data from four different sources: Burbio [1], MCH Strategic Data [2], the AEI/Return to Learn Tracker [3], and state dashboards [4-20]. These data were combined using a Hidden Markov model which infers the sequence of learning modalities (In-Person, Hybrid, or Remote) for each district that is most likely to produce the modalities reported by these sources. This model was trained using data from the 2020-2021 school year. Metadata describing the location, number of schools and number of students in each district comes from NCES [21].

• The metrics listed for each school learning modality reflect totals by district and the number of enrolled students per district for which data are available. School districts represented here exclude private schools and include the following NCES subtypes:
  • Public school district that is NOT a component of a supervisory union
  • Public school district that is a component of a supervisory union
  • Independent charter district
• “BI” in the state column refers to school districts funded by the Bureau of Indian Education.

Technical Notes

• Data from September 1, 2020 to June 25, 2021 correspond to the 2020-2021 school year. During this timeframe, all four sources of data were available. Inferred modalities with a probability below 0.75 were deemed inconclusive and were omitted.
• Data for the month of July may show “In Person” status although most school districts are effectively closed during this time for summer break. Users may wish to exclude July data from use for this reason where applicable.

This guidance supports high quality investigations that will contribute to public health’s collective understanding of COVID-19 transmission in all types of school settings and the utility of mitigation measures implemented. A systematic approach to outbreak response, including an investigation that examines cases, contacts, their interactions and environment, will help to produce higher quality evidence and will support public health officials in making evidence informed policy decisions. The guidelines will provide information applicable to any type of outbreak investigation and will highlight specific considerations for outbreaks occurring within an educational setting including daycares and schools.

On March 2, 2022 DC Health announced the District’s new COVID-19 Community Level key metrics and reporting. COVID-19 cases are now reported on a weekly basis. District of Columbia Public Schools testing for the number of positive tests and quarantined. Due to rapidly changing nature of COVID-19, data for March 2020 is limited.General Guidelines for Interpreting Disease Surveillance DataDuring a disease outbreak, the health department will collect, process, and analyze large amounts of information to understand and respond to the health impacts of the disease and its transmission in the community. The sources of disease surveillance information include contact tracing, medical record review, and laboratory information, and are considered protected health information. When interpreting the results of these analyses, it is important to keep in mind that the disease surveillance system may not capture the full picture of the outbreak, and that previously reported data may change over time as it undergoes data quality review or as additional information is added. These analyses, especially within populations with small samples, may be subject to large amounts of variation from day to day. Despite these limitations, data from disease surveillance is a valuable source of information to understand how to stop the spread of COVID19.

The 2021-2022 School Learning Modalities dataset provides weekly estimates of school learning modality (including in-person, remote, or hybrid learning) for U.S. K-12 public and independent charter school districts for the 2021-2022 school year and the Fall 2022 semester, from August 2021 – December 2022.

We have developed a guidance for managing COVID-19. This guidance is for: health professionals who manage clinical care, and infection prevention and control within health care facilities, health professionals who develop public health advice, policies and programs, and a broad range of sectors, including: industry, youth and child care settings, community-based services (for example, services for homeless people), death services and faith community leaders.

During the COVID-19 induced lockdown in France during the year 2020, many schools had to shut down their physical activity, which left students disoriented in many ways. As some were in their last years of education, the source wanted to investigate ways in which French students had access to guidance, when orientating themselves towards higher studies or finding a job. Thus, many informed themselves directly on the school platform, whereas 70 percent looked at counselling and orientation websites. About half of the respondents used social networks.

N. Thakur, “A Large-Scale Dataset of Twitter Chatter about Online Learning during the Current COVID-19 Omicron Wave,” Journal of Data, vol. 7, no. 8, p. 109, Aug. 2022, doi: 10.3390/data7080109

Abstract

The COVID-19 Omicron variant, reported to be the most immune evasive variant of COVID-19, is resulting in a surge of COVID-19 cases globally. This has caused schools, colleges, and universities in different parts of the world to transition to online learning. As a result, social media platforms such as Twitter are seeing an increase in conversations, centered around information seeking and sharing, related to online learning. Mining such conversations, such as Tweets, to develop a dataset can serve as a data resource for interdisciplinary research related to the analysis of interest, views, opinions, perspectives, attitudes, and feedback towards online learning during the current surge of COVID-19 cases caused by the Omicron variant. Therefore this work presents a large-scale public Twitter dataset of conversations about online learning since the first detected case of the COVID-19 Omicron variant in November 2021. The dataset is compliant with the privacy policy, developer agreement, and guidelines for content redistribution of Twitter and the FAIR principles (Findability, Accessibility, Interoperability, and Reusability) principles for scientific data management.

Data Description

The dataset comprises a total of 52,984 Tweet IDs (that correspond to the same number of Tweets) about online learning that were posted on Twitter from 9th November 2021 to 13th July 2022. The earliest date was selected as 9th November 2021, as the Omicron variant was detected for the first time in a sample that was collected on this date. 13th July 2022 was the most recent date as per the time of data collection and publication of this dataset.

The dataset consists of 9 .txt files. An overview of these dataset files along with the number of Tweet IDs and the date range of the associated tweets is as follows. Table 1 shows the list of all the synonyms or terms that were used for the dataset development.

This dataset contains dates for the implementations of the following interventions in 50 US states plus Shelby County TN in response to COVID-19. Each intervention date has an associated comment containing sources for that date and a rationale when the decision was not strictly objective. Interventions are valid to 4/25/20 after which some states began to reverse some interventions.

• schools_universities
  • Primary/secondary school closing; partial closing is OK; State university closing if it precedes primary/secondary
• travel_restrictions
  • Out of state travel quarantine restrictions OR state-level guidance to avoid traveling out of state
• public_events
  • Banning of ALL public events of more than 100 participants
• sport
  • Banning/canceling of sporting events. Banning of public events of 1000 or more also qualifies.
• lockdown
  • Definitions vary, but include: banning of non-essential gatherings/business operations, ordering stay at home except for exercise and essential tasks; stay at home/safer at home orders
  • Lockdown encompasses all other intervensions by definition, so if a state skips multiple interventions and goes to lockdown, the lockdown date is used for those interventions as well.
• social_distancing_encouraged
  • State advice on distancing including: work from home, reduce public transport, avoid non-essential contact; any guidance for maintaining a physical distance from others will also qualify. Mere words "social distancing" do not count unless they are elaborated with what that means in practice. Messaging must be to public and not selected group (e.g. state employees).
• self_isolating_if_ill
  • Strong recommendations/laws about self-isolating if showing COVID like symptoms; Statewide testing implies this, so whichever comes first. Messaging must be to public and not selected group (e.g. state employees).

This study aimed to clarify the adaptation features of University students exposed to fully online education during the novel coronavirus disease 2019 (COVID-19) pandemic and to identify accompanying mental health problems and predictors of school adaptation. The pandemic has forced many universities to transition rapidly to delivering online education. However, little is known about the impact of this drastic change on students' school adaptation. This cross-sectional study used an online questionnaire, including assessments of impressions of online education, study engagement, mental health, and lifestyle habits. In total, 1,259 students were assessed. The characteristics of school adaptation were analyzed by a two-step cluster analysis. The proportion of mental health problems was compared among different groups based on a cluster analysis. A logistic regression analysis was used to identify predictors of cluster membership. P-values < 0.05 were considered statistically significant. The two-step cluster analysis determined three clusters: school adaptation group, school maladaptation group, and school over-adaptation group. The last group significantly exhibited the most mental health problems. Membership of this group was significantly associated with being female (OR = 1.42; 95% CI 1.06–1.91), being older (OR = 1.21; 95% CI 1.01–1.44), those who considered online education to be less beneficial (OR = 2.17; 95% CI 1.64–2.88), shorter sleep time on weekdays (OR = 0.826; 95% CI 0.683–.998), longer sleep time on holidays (OR = 1.21; 95% CI 1.03–1.43), and worse restorative sleep (OR = 2.27; 95% CI 1.81–2.86). The results suggest that academic staff should understand distinctive features of school adaptation owing to the rapid transition of the educational system and should develop support systems to improve students' mental health. They should consider ways to incorporate online classes with their lectures to improve students' perceived benefits of online education. Additionally, educational guidance on lifestyle, such as sleep hygiene, may be necessary.

This document provides guidance specific to the COVID-19 pandemic in outpatient and ambulatory care settings. Outpatient and ambulatory care settings are defined here as those providing health care on an outpatient basis and can include hospital-based and non-hospital based clinics, physician offices, community health centers and urgent care centers.

Provides public health guidance for how long students are required to stay home from school when they have different symptoms of COVID-19.

In order to develop technical guidance to support F/P/T public health authorities and front-line clinicians in health care settings responding to the novel coronavirus causing COVID-19, a number of assumptions were taken to develop interim guidance documents.
