The correspondence between the structure of the terrestrial mobility network and the spreading of COVID-19 in Brazil. Cad Saude Publica. 2020;36(9):e00184820 Authors: Freitas VLS, Konstantyner TCRO, Mendes JF, Sepetauskas CSDN, Santos LBL Abstract The inter-cities mobility network is of great importance in understanding outbreaks, especially in Brazil, a continental-dimension country. We adopt the data from the Brazilian Ministry of Health and the terrestrial flow of people between cities from the Brazilian Institute of Geography and Statistics database in two scales: cities from Brazil, without the North region, and from the São Paulo State. Grounded on the complex networks approach, and considering that the mobility network serves as a proxy for the SARS-CoV-2 spreading, the nodes and edges represent cities and flows, respectively. Network centrality measures such as strength and degree are ranked and compared to the list of cities, ordered according to the day that they confirmed the first case of COVID-19. The strength measure captures the cities with a higher vulnerability of receiving new cases. Besides, it follows the interiorization process of SARS-CoV-2 in the São Paulo State when the network flows are above specific thresholds. Some countryside cities such as Feira de Santana (Bahia State), Ribeirão Preto (São Paulo State), and Caruaru (Pernambuco State) have strength comparable to states' capitals. Our analysis offe...

CONCLUSIONS: Systems-level interventions may alleviate distress for most providers without the need for specialized mental health intervention. Psychotherapeutic support and referral to specialty care should be available to health workers with severe and intense adverse psychological outcomes during and beyond the COVID-19 pandemic. Evidence-based interventions are urgently needed to better serve health workers both during and following epidemics/pandemics. PMID: 33019857 [PubMed - as supplied by publisher]

CONCLUSIONS: COVID-19, SARS and MERS have significant detrimental effect on pregnancy. Rapid intervention, treatment, and intensive care support are essential for infected pregnant. Timely delivery is important in order to avoid intrauterine fetal death. PMID: 33015821 [PubMed - in process]

ConclusionsLack of availability of sound scientific knowledge inevitably lead unreliable news to spread over the population, preventing people to disentangle them form reliable information. Even if additional studies are needed to replicate and strengthen our results, these findings represent initial evidence to derive recommendations based on actual data for subjects with autoimmune diseases.

ConclusionsThere are differences in the regional and economic distribution of international and Chinese cooperation networks. International research is often related to timely issues mainly by focusing on emergency preparedness and monitoring of public health events, while China has focused on public health emergencies and their disposition. International research began on terrorism and bioterrorism, followed by disaster planning and emergency preparedness, epidemics, and infectious diseases. China considered severe acute respiratory syndrome as the starting research background and the legal system construction as the rese...

Conclusions: Our results illustrate how the integration of data coming from multiple sources could help trigger an early alarm in the context of an emerging disease. Good information data systems, able to produce earlier alerts, could have avoided a general lockdown in France.

Introduction: Coronavirus disease 2019 (COVID-19) has substantially impacted the healthcare delivery system in Tehran, Iran. The country ’s first confirmed positive test for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was on February 18, 2020. Since then, the number of cases has steadily increased in Iran and worldwide. Emergency medical services (EMS) quickly adapted its operations to accommodate a greater number of patients, and it worked to decrease the risk of COVID-19 spread among EMS personnel, given the disease’s high transmissibility.Methods: We evaluated the chief complaint as well as ...

AbstractPurpose of ReviewIn December 2019, outbreaks of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected pneumonia patients were discovered in Wuhan City, Hubei Province, China. With the spread of the epidemic, new cases have been found in other regions of China and abroad. This review summarizes the current coronavirus disease 2019 (COVID-19) transmission pathways, high-risk factors, diagnostic points, pathogenesis, and therapeutic drugs to provide the prevention and treatment theories for COVID-19.Recent FindingsCOVID-19 is highly contagious and is transmitted mainly through the respiratory tract. Mo...

In this study, we utilize a mathematical model motivated by aspects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) natural history to investigate how evolutionary changes in survival may influence several aspects of disease dynamics at the epidemiological scale. Across virulence–survival relationships (where these traits are either positively or negatively correlated), we found that small changes (5% above and below the nominal value) in survival can have a meaningful effect on certain outbreak features, including R0, and on the size of the infectious peak in the population. These results highlig...

In this report, we present updated 30-day projections, together with a visual validation of the original forecasts. We continue to model a baseline'status quo'scenario, assuming all control measures in place on 8 September 2020 will be continued until the end of the projection period (14 October 2020). In this version, we have included data on testing rates to simulate the increased ascertainment of milder cases. For almost all countries, testing data is correct until 23 August. We have also included the use of face masks (both mandatory and voluntary) as a means for reducing both transmission and susceptibility to infecti...
