“…This would then reserve resources for increased sampling during periods of high transmission when the reduction in infections per test is high. A similar strategy appeared to provide favorable results at Furman University (13). This conclusion is similar to Paltiel et al (39) effective, and to Hambridge, Kahn, and Onnela (34), who found that increasing the frequency of surveillance testing has smaller effects on the infection rate when R 0 is low than when it is high.…”

On a local level, university students regularly mix with surrounding communities through student employment, peers in off-campus housing, interactions with friends and family outside of the university, and participation in community events.…”

Emerging infection diseases (EIDs) are an increasing threat to global public health, especially when the disease is newly emerging. Institutions of higher education (IHEs) are particularly vulnerable to EIDs because student populations frequently share high-density residences and strongly mix with local and distant populations. In fall 2020, IHEs responded to a novel EID, COVID-19. Here, we describe Quinnipiac University’s response to SARS-CoV-2 and evaluate its effectiveness through empirical data and model results. Using an agent-based model to approximate disease dynamics in the student body, the University established a policy of dedensification, universal masking, surveillance testing via a targeted sampling design, and app-based symptom monitoring. After an extended period of low incidence, the infection rate grew through October, likely due to growing incidence rates in the surrounding community. A super-spreader event at the end of October caused a spike in cases in November. Student violations of the University’s policies contributed to this event, but lax adherence to state health laws in the community may have also contributed. The model results further suggest that the infection rate was sensitive to the rate of imported infections and was disproportionately impacted by non-residential students, a result supported by the observed data. Collectively, this suggests that campus-community interactions play a major role in campus disease dynamics. Further model results suggest that app-based symptom monitoring may have been an important regulator of the University’s incidence, likely because it quarantined infectious students without necessitating test results. Targeted sampling had no substantial advantages over simple random sampling when the model incorporated contact tracing and app-based symptom monitoring but reduced the upper boundary on 90% prediction intervals for cumulative infections when either was removed. Thus, targeted sampling designs for surveillance testing may mitigate worst-case outcomes when other interventions are less effective. The results’ implications for future EIDs are discussed.

“…As of June 2021, there have been 173 million COVID-19 cases worldwide, with new cases rapidly increasing at an alarming rate and showing no signs of abating [1]. If COVID-19 infection is not detected early enough, it can induce a flu-like sickness that can proceed to acute respiratory distress syndrome (ARDS), which can be deadly [2][3][4][5][6][7][8]. Due to limited resources and the amount of data accessible to the scientific community, early diagnosis of COVID-19 remains a tough challenge despite recent worldwide research efforts in healthcare [9].…”

In the recent pandemic, accurate and rapid testing of patients remained a critical task in the diagnosis and control of COVID-19 disease spread in the healthcare industry. Because of the sudden increase in cases, most countries have faced scarcity and a low rate of testing. Chest X-rays have been shown in the literature to be a potential source of testing for COVID-19 patients, but manually checking X-ray reports is time-consuming and error-prone. Considering these limitations and the advancements in data science, we proposed a Vision Transformer-based deep learning pipeline for COVID-19 detection from chest X-ray-based imaging. Due to the lack of large data sets, we collected data from three open-source data sets of chest X-ray images and aggregated them to form a 30 K image data set, which is the largest publicly available collection of chest X-ray images in this domain to our knowledge. Our proposed transformer model effectively differentiates COVID-19 from normal chest X-rays with an accuracy of 98% along with an AUC score of 99% in the binary classification task. It distinguishes COVID-19, normal, and pneumonia patient’s X-rays with an accuracy of 92% and AUC score of 98% in the Multi-class classification task. For evaluation on our data set, we fine-tuned some of the widely used models in literature, namely, EfficientNetB0, InceptionV3, Resnet50, MobileNetV3, Xception, and DenseNet-121, as baselines. Our proposed transformer model outperformed them in terms of all metrics. In addition, a Grad-CAM based visualization is created which makes our approach interpretable by radiologists and can be used to monitor the progression of the disease in the affected lungs, assisting healthcare.

Objective: This study assessed the seroprevalence of SARS-CoV-2 antibodies at two timepoints to evaluate the effectiveness of COVID-19 precautions in two colleges. Participants: The study enrolled students, faculty, and staff from Covenant and Geneva Colleges. Methods: During the fall of 2020 the Mayo Clinic Vaccine Research Group partnered with Vibrant America to hand out self-administered finger stick antibody tests at the start of the fall semester and again two months later. Results: The study enrolled 305 participants from Covenant and 671 from Geneva College at timepoint 1 and 198 participants from Covenant and 554 from Geneva College at timepoint 2. Seroprevalence rates were 2.3% and 1.6% at timepoint 1, and 0.5% and 3.97% at timepoint 2 at Covenant and Geneva Colleges, respectively. Conclusion: The results of this study suggest that implementation of strict preventive measures may have kept the spread of COVID-19 low at these colleges during the study period.
