MMWR. Morbidity and Mortality Weekly Report; Rebmann T, Loux TM et. al.

Sep 10th, 2021 - Universities open for in-person instruction during the 2020-21 academic year implemented a range of prevention strategies to limit the transmission of SARS-CoV-2, the virus that causes COVID-19, including physical distancing, mask use, vaccination, contact tracing, case investigation, and quarantine protocols (1). However, in some academic programs, such as health-related programs, aviation, an...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8408313
International Journal of Public Health; Buja A, Zabeo F et. al.

Sep 7th, 2021 - Objectives: Benefits of school attendance have been debated against SARS-CoV-2 contagion risks. This study examined the trends of contagion before and after schools reopened across 26 countries in the European Union. Methods: We compared the average values of estimated R t before and after school reopening, identifying any significant increase with a one-sample t-test. A meta-analysis and meta-...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8404624
Journal of the American College of Cardiology; Clemente-Moragón A, Martínez-Milla J et. al.

Sep 4th, 2021 - Severe coronavirus disease-2019 (COVID-19) can progress to an acute respiratory distress syndrome (ARDS), which involves alveolar infiltration by activated neutrophils. The beta-blocker metoprolol has been shown to ameliorate exacerbated inflammation in the myocardial infarction setting. The purpose of this study was to evaluate the effects of metoprolol on alveolar inflammation and on respirat...

MMWR. Morbidity and Mortality Weekly Report; Matthias J, Patrick S et. al.

Sep 3rd, 2021 - On June 30, 2021, the Illinois Department of Public Health (IDPH) contacted CDC concerning COVID-19 outbreaks at two events sponsored by the same organization: a 5-day overnight church camp for persons aged 14-18 years and a 2-day men's conference. Neither COVID-19 vaccination nor COVID-19 testing was required before either event. As of August 13, a total of 180 confirmed and probable cases had...

MMWR. Morbidity and Mortality Weekly Report; Doyle K, Teran RA et. al.

Sep 3rd, 2021 - To prevent transmission of SARS-CoV-2, the virus that causes COVID-19, colleges and universities have implemented multiple strategies including testing, isolation, quarantine, contact tracing, masking, and vaccination. In April 2021, the Chicago Department of Public Health (CDPH) was notified of a large cluster of students with COVID-19 at an urban university after spring break. A total of 158 ...

Proceedings of the National Academy of Sciences of the Un... Wang J, Alipour M et. al.

Sep 2nd, 2021 - After the Spanish flu pandemic, it was apparent that airborne transmission was crucial to spreading virus contagion, and research responded by producing several fundamental works like the experiments of Duguid [J. P. Duguid, J. Hyg. 44, 6 (1946)] and the model of Wells [W. F. Wells, Am. J. Hyg. 20, 611-618 (1934)]. These seminal works have been pillars of past and current guidelines published b...

Sep 1st, 2021 - Data on transmission of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), among college athletes are limited. In August 2020, the Chicago Department of Public Health (CDPH) was notified of a cluster of COVID-19 cases among a university's men's and women's soccer teams. CDPH initiated an investigation, interviewed members of both teams, and collated laboratory data to unders...

A Case Report of Fetal Thrombotic Vasculopathy in a COVID Placenta.
https://www.ncbi.nlm.nih.gov/pubmed/34452898
Annals of Clinical and Laboratory Science; Mai B, Alrais M et. al.

Aug 29th, 2021 - COVID-19 has affected patients of all ages and demographics, not excluding pregnant women. The effects of COVID-19 on pregnant women are still largely unknown. Several adverse perinatal outcomes have been reported in COVID-19-positive pregnant women, including pre-eclampsia, miscarriage, pre-term labor, and stillbirth. Histopathological examination of COVID-19 placentas can contribute significa...

Factors Associated With Household Transmission of SARS-CoV-2: An Updated Systematic Rev...
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8397928
JAMA Network Open; Madewell ZJ, Yang Y et. al.

Aug 28th, 2021 - A previous systematic review and meta-analysis of household transmission of SARS-CoV-2 that summarized 54 published studies through October 19, 2020, found an overall secondary attack rate (SAR) of 16.6% (95% CI, 14.0%-19.3%). However, the understanding of household secondary attack rates for SARS-CoV-2 is still evolving, and updated analysis is needed. To use newly published data to further th...

PloS One; Domènech-Montoliu S, Pac-Sa MR et. al.

Aug 27th, 2021 - Mass gathering events (MGEs) are associated with the transmission of COVID-19. Between 6 and 10 March 2020, several MGEs related to the Falles festival took place in Borriana, a municipality in the province of Castellon (Spain). The aim of this study was to estimate the incidence of COVID-19 and its association with these MGEs, and to quantify the potential risk factors of its occurrence. Durin...

The spreading of SARS-CoV-2: Interage contacts and networks degree distribution.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8386875
PloS One; Sage L, Albertini M et. al.

Aug 26th, 2021 - Notable cross-country differences exist in the diffusion of the Covid-19 and in its lethality. Contact patterns in populations, and in particular intergenerational contacts, have been argued to be responsible for the most vulnerable, the elderly, getting infected more often and thus driving up mortality in some context, like in the southern European one. This paper asks a simple question: is it...

Plastic and Reconstructive Surgery; Hamilton KL, Rohrich RJ

Aug 26th, 2021 - The novel coronavirus, severe acute respiratory syndrome coronavirus 2, responsible for the coronavirus disease of 2019 (COVID-19) pandemic, has claimed over 2 million lives to date and brought the global economy to a halt, including elective surgery. As the authors emerge from lockdown, new protocols must be implemented to minimize risk by means of appropriate screening of their patients, surg...

Lessons Learned in Managing Patients with Colorectal Cancer During the COVID-19 Pandemic.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8381863
Current Treatment Options in Oncology; Mukherji R, Marshall JL

Aug 24th, 2021 - The COVID-19 pandemic forced us to rapidly and dramatically shift our medical priorities and decision making. With little literature or experience to rely on, the initial priority was to minimize patient exposure to the hospital and to others. It remains unclear whether cancer patients are at higher risk of infection or serious complications, or if it is our traditional therapies that place the...

Infectious Diseases of Poverty; Liu J, Chen X et. al.

Aug 23rd, 2021 - The coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) is pandemic. However, the origins and global transmission pattern of SARS-CoV-2 remain largely unknown. We aimed to characterize the origination and transmission of SARS-CoV-2 based on evolutionary dynamics. Using the full-length sequences of SARS-CoV-2 with intact geographic, ...

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8379567
Globalization and Health; Kelly D, Bambury N et. al.

Aug 23rd, 2021 - International air travel has been highlighted as a concern since the beginning of the COVID-19 pandemic with respect to importation of cases. We summarise the available evidence for in-flight transmission of wild type SARS-CoV-2 during 2020, and for imported COVID-19 clusters to cause outbreaks. This paper provides a data baseline prior to the emergence of new mutations causing SARS-CoV-2 varia...
