In Portugal, early childhood education and care services for children under-three were the first educational services to reopen after periods of lockdown. COVID-19 prevention and control measures had to be implemented nationwide, but no knowledge was yet produced on their impact in educational settings. This study aimed to map the implementation…

As the threat of COVID-19 recedes, China has entered a new phase of pandemic prevention and control and preschools have resumed offline education. This study examined 1,553 Chinese preschool teachers' work experiences, data for whom were collected since the new pandemic prevention and control measures were implemented in China. All preschool…

Current models of COVID-19 transmission predict infection from reported or assumed interactions. Here we leverage high-resolution observations of interaction to simulate infectious processes. Ultra- Wide Radio Frequency Identification (RFID) systems were employed to track the real-time physical movements and directional orientation of children and…

The outburst of the coronavirus pandemic in Poland has led to specific measures related to COVID, which affected unequally different age groups. Children were presented as "spreaders" of the disease, and a threat to the societies' safety. Such fears led to new disciplining practices, such as prohibiting children from leaving the house…

Background: The most effective approach to food allergy management is to avoid consuming the specific allergens that trigger an allergic reaction. It is crucial to make school environments prepared for the potential of food allergic reactions, including anaphylaxis, which is a rare but documented outcome. The high prevalence of anaphylactic…

Since the COVID-19 pandemic began, children have presented with increased psychiatric symptoms. Little research has been done regarding early childhood mental health, particularly those from vulnerable socioeconomic contexts who are exposed to adversity. We aimed to assess mental health and the impacts of the pandemic on this population. A survey…

This study highlights a survey on 5783 kindergarten teachers' occupational commitment and its influencing factors in the socioeconomic context of China during the COVID-19 pandemic. Data were collected through the WenJuanXing public online platform. Quantitative analysis results showed that kindergarten teachers' occupational commitment was…

Background: Top public health experts and organizations strongly recommend universal masking for children older than 2 years old during the COVID-19 pandemic, but speculate it may be difficult for young children. This study sought to assess the usage of cloth face masks in grades pre-K-2 and identify associated characteristics and adverse events.…

During the advancement of COVID-19, many safety protocols, including facial masks, were incorporated into public settings. The Centers for Disease Control and Prevention (CDC) (2021), due to safety regulations, recommended wearing face masks when in close contact with other people in public environments, such as in a classroom, where social…

Background: Universal masking, with additional layered prevention strategies, was an essential tool for limiting the transmission of SARS-CoV-2 and ensuring a safe return to in-person learning for kindergarten through 12th grade (K-12) students and staff. Few studies have examined mask adherence in this setting and none have described types of…

The COVID-19 pandemic hit the United States in early 2020. With it, came a range of concerns, panic, and scrambling for "quick fixes," as families learned to navigate rapid and sometimes confusing pandemic changes. Thirty million Americans were under- or uninsured at the start of the pandemic, so both preventive measures and access to…

Background: At the onset of the COVID-19 pandemic, schools closed across the United States. Given the impact of virtual learning and lost access to school resources, schools eventually reopened with COVID-19 mitigation protocols in place. This qualitative study sought to understand parental perceptions of school-based COVID-19 mitigation…

Background: Test-to-stay (TTS) is a strategy to limit school exclusion following an exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We evaluated the use of TTS within universally masked kindergarten through 12th grade (K-12) school settings following household SARS-CoV-2 exposure. Methods: Three hundred twenty-two…

This paper details the research design of a multidisciplinary, multi-method, collaborative research project investigating health communication from the experiences of the early childhood education (ECE) sector during the COVID-19 pandemic. With the rapidly evolving pandemic, the ECE sector was instantly tasked with expanding their required health…

In an effort to reduce viral transmission, many schools are planning to reduce class size if they have not reduced it already. Yet the effect of class size on transmission is unknown. To determine whether smaller classes reduce school absence, especially when community disease prevalence is high, we merge data from the Project STAR randomized…
