The outbreak of the 2019 novel coronavirus (COVID-19) has attracted global attention. During the Chinese New Year holiday, population outflow from Wuhan induced the spread of the epidemic to other cities in China. This study analyzed massive intercity movement data from Baidu and epidemic data to study how intercity population outflows affected the spatiotemporal spread of the epidemic. This study further investigated how urban factors influenced the spatiotemporal spread of COVID-19. The analysis indicates that intercity movement was an important factor in the spread of the epidemic in China, and the impact of intercity movement on the spread was heterogeneous across different classes of cities. The spread of the epidemic also varied among cities and was affected by urban factors including the total population, population density, and gross domestic product (GDP). The findings have implications for public health management. Mega-cities should consider tougher measures to contain the spread of the epidemic compared with other cities. It is of great significance for policymakers in any nation to assess the potential risk of epidemics and make cautious plans ahead of time.

AbstractTo ensure the safe operation of schools, workplaces, nursing homes, and other businesses during COVID-19 pandemic there is an urgent need to develop cost-effective public health strategies. Here we focus on the cruise industry which was hit early by the COVID-19 pandemic, with more than 40 cruise ships reporting COVID-19 infections. We apply mathematical modeling to assess the impact of testing strategies together with social distancing protocols on the spread of the novel coronavirus during ocean cruises using an individual-level stochastic model of the transmission dynamics of COVID-19. We model the contact network, the potential importation of cases arising during shore excursions, the temporal course of infectivity at the individual level, the effects of social distancing strategies, different testing scenarios characterized by the test’s sensitivity profile, and testing frequency. Our findings indicate that PCR testing at embarkation and daily testing of all individuals aboard, together with increased social distancing and other public health measures, should allow for rapid detection and isolation of COVID-19 infections and dramatically reducing the probability of onboard COVID-19 community spread. In contrast, relying only on PCR testing at embarkation would not be sufficient to avert outbreaks, even when implementing substantial levels of social distancing measures.

The Impact

On March 11, 2020, the World Health Organisation (WHO) declared a global health pandemic, due to the spread of a novel coronavirus, later named “Covid-19”. The spread of Covid-19 led to social isolation, distancing and a number of restrictive measures in Malta.  The aim of this paper is to analyse the impact of Covid-19 and the subsequent restrictive measures on persons with disability and their caregivers and families in Malta. Using thematic analysis, the study found that a variety of impacts ranging from a sense of isolation, lack of essential services being provided, additional difficulties encountered at the place of work and education and measures that were not sufficiently tailored for persons with disability issued by public health authorities. Underlying the additional difficulties brought about by Covid-19, structural difficulties to access essential services as well as ignorance from policy makers and politicians and the added “vulnerable-ization” of persons with disabilities were found to be highly impacting factors that pervade the experience of persons with disabilities and their caregivers.

The Impact

The novel coronavirus disease 2019 (COVID-19) outbreak, caused by the pathogenic severe acute respiratory syndrome-2 (SARS-CoV-2) virus, is exponentially spreading across the globe. As there is paucity of published literature, the influence of COVID-19 on community health remains unclear. Therefore, we aimed to conduct a systematic review of the literature on the impact of COVID-19 on community health. The current systematic review was performed utilizing electronic databases, i.e., PubMed, MEDLINE, and EMBASE. We searched for the keywords "COVID-19" AND "community health" between January 1, 2020, until May 10, 2020. Although, limited evidence is available regarding quarantine to prevent COVID‐19, most studies considered quarantine as an essential public health measure to minimize rate of infection and mortality. Under these circumstances, people should focus on maintaining personal hygiene, proper nutrition, and extreme social distancing to reduce the risk of COVID-19. Besides, that there is a need to provide professional psychological support to reduce mental ill-health. We have highlighted two different public health approaches in South Asian countries, namely Nepal and India.

As we begin 2020, Microbiology is dominating the news with the emergence and rapid dissemination of the novel coronavirus COVID-19. The impact of COVID-19 on public health, with significant financial, logistical and social repercussions, has quickly become apparent. As microbiologists we have an important role to play during this time because we can use our knowledge, expertise and experience to educate the community around us, and to reduce the panic that results from fear and misinformation. It is also critical that we ensure that racial groups are not stigmatised because of an infectious disease. A co-ordinated global effort is required to tackle this new infectious threat, and we are an important local part of this effort. It is also important to develop strategies that can be deployed when the next threat emerges, as it surely will.

Culture independent diagnostic tests (CIDT) for detection of pathogens in clinical specimens have become widely adopted in Australian pathology laboratories. Pathology laboratories are the primary source of notification of pathogens to state and territory surveillance systems. Monitoring and analysis of surveillance data is integral to guiding public health actions to reduce the incidence of disease and respond to outbreaks. As with any change in testing protocol, the advantages and disadvantages of the change from culture based testing to culture independent testing need to be weighed up and the impact on surveillance and outbreak detection assessed. This article discusses the effect of this change in testing on surveillance and public health management of pathogens in Australia, with specific focus on gastrointestinal pathogens.

Introdução: O novo coronavírus é responsável pela síndrome respiratória aguda grave, causando óbito, em 5 meses de pandemia, de 646 mil indivíduos mundialmente. As principais formas de transmissão identificadas são gotículas de saliva expelidas ao falar e tossir ou pelo contato em uma superfície com secreções salivares, com característica agressiva de contágio e potencial letalidade. Objetivo: Relatar as práticas do serviço radiológico em tempos de pandemia e evidenciar práticas seguras de biossegurança para o Cirurgião-Dentista. Métodos: Para elaboração deste trabalho foram selecionados 13 artigos utilizando a base de dados do Pubmed. Foram utilizados como descritores “Coronavirus Infections”, “Betacoronavirus”, “Dentistry”, “Radiology” e “Containment of Biohazards. Os critérios de inclusão foram artigos publicados em inglês, espanhol e português com os resumos disponíveis, do ano de 2020. Resultados: Os Cirurgiões-Dentistas estão entre os profissionais que mais sofrem risco de contaminação, uma vez que estão expostos a riscos biológicos e contato direto com a saliva, sendo necessário, neste cenário crítico de pandemia do coronavírus, adotar medidas mais eficazes de prevenção e controle de infecção a fim de evitar ou reduzir ao máximo a transmissão deste vírus. Na Radiologia Odontológica, a baixa incidência de aerossóis não exclui a possibilidade de contaminação pelo contato com fluido salivar nas tomadas radiográficas intrabucais, preconizando radiografias extrabucais. Conclusão: A presente revisão de literatura é baseada em relevantes diretrizes e pesquisas, introduzindo conhecimentos essenciais sobre o coronavírus, condutas a serem adotadas em ambiente odontológico e fornece protocolos de orientações recomendadas para dentistas e estudantes.Descritores: Infecções por Coronavirus; Betacoronavirus; Odontologia; Radiologia; Contenção de Riscos Biológicos.ReferênciasOrganização Mundial da Saúde (OMS).

The Impact

The COVID-19 global pandemic highlights pre-existing inequities as well as the challenge of ensuring the protection of children’s human rights in countries like Canada that have ratified the United Nations Convention on the Rights of the Child. SARS-CoV-2, referred to as the 2019 novel Coronavirus disease or COVID-19, presents a significant threat to public health. Although children are considered to be low risk of contracting, spreading, and serious complications of the disease, are considerably impacted by COVID-19 government-sanctioned distancing measures. COVID-19 is a persistent public health threat, thus, the long-term consequences are largely unknown. This qualitative research study, a content analysis of online Canadian media reports of COVID-19 and children, engaged transdisciplinary social justice methodology, social constructions of childhood at the intersection of race, socio-economic status, gender, and disability. The findings suggest COVID-19 reinforces the impact of social exclusion and economic disparity on equity-seeking young people and families in Canada.

The Impact

The ongoing COVID-19 pandemic has caused worldwide socioeconomic unrest, forcing governments to introduce extreme measures to reduce its spread. Being able to accurately forecast when the outbreak will hit its peak would significantly diminish the impact of the disease, as it would allow governments to alter their policy accordingly and plan ahead for the preventive steps needed such as public health messaging, raising awareness of citizens and increasing the capacity of the health system. This study investigated the accuracy of a variety of time series modeling approaches for coronavirus outbreak detection in ten different countries with the highest number of confirmed cases as of 4 May 2020. For each of these countries, six different time series approaches were developed and compared using two publicly available datasets regarding the progression of the virus in each country and the population of each country, respectively. The results demonstrate that, given data produced using actual testing for a small portion of the population, machine learning time series methods can learn and scale to accurately estimate the percentage of the total population that will become affected in the future.

UNSTRUCTURED After the global spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), research has highlighted several aspects of the pandemic, focusing on clinical features and risk factors associated with infection and disease severity. However, emerging results on the role of smoking in SARS-CoV-2 infection susceptibility or Novel Coronavirus Disease 2019 (COVID-19) outcomes are conflicting, and their robustness remains uncertain. In this context, this study aims at quantifying the proportion of SARS-CoV-S antibody seroprevalence, studying the changes in antibody levels over time, and analyzing the association between the biochemically verified smoking status and SARS-CoV-2 infection. The research design involves a 6-month prospective cohort study with serial sampling of the same individuals. Each participant will be surveyed about their demographics and COVID-19-related information, and blood sampling will be collected upon recruitment and at specified follow-up time points (namely, after 8 and 24 weeks). Blood samples will be screened for the presence of SARS-CoV-2 specific antibodies and serum cotinine, being the latter the principal metabolite of nicotine, which will be used to assess participants’ smoking status. Discussion: Overall, we expect to find a higher prevalence of antibodies in individuals at high-risk for viral exposure (i.e., healthcare personnel or other essential workers), according to previous literature, and to refine current estimates on the association between smoking status and SARS-CoV-2/COVID-19. The added value of this research is that the current smoking status of the population to be studied will be biochemically verified, in order to avoid the bias associated with self-reported smoking status. As such, the results from this survey may provide actionable metric to study the role of smoking in SARS-CoV-2 infection and COVID-19 outcomes, and therefore implement the most appropriate public health measures to control the pandemic. Results may also serve as a reference for future clinical research and the methodology could be exploited in public health sectors and policies.

Abstract Background World Health Organization (WHO) declared that the outbreak of novel coronavirus (2019-nCoV) constituted a Public Health Emergency of International Concern (PHEIC) on 30 January 2020 and characterized the novel coronavirus disease (COVID-19) as a pandemic on 11 March 2020. India enacted such measures early on for effective mitigation and suppression to reduce community transmission, including an onerous national lockdown. The impact of the health system governance is quite apparent among all stakeholders including the public in such emergency contexts. Methods We compiled the daily data on the number of COVID-19 cases, recoveries and deaths from January 30th until June 16th, 2020. Different stages were categorized from post PHEIC declaration (pre-lockdown) phase to lockdown phases and unlocking phase as implemented. The several measures adopted by the national government were structured in four broad categories as Governance and socioeconomic, travel restrictions, lockdown and public health measures. These measures were compared during each phase. Results It was revealed that while the cases are rising the phased restrictions has helped in delaying the peak and remarkably interrupted the rate of transmission. The national average doubling rate was 3 days at the beginning which improved to 22 days. The basic reproduction number remained close to 1 during the last week of lockdown. However, the initial interruption of needed aid and technical support had negative social and economic impacts on the affected population. Conclusions As the situation abates following the measures adopted by the government, an articulate strategy of unlocking through increased testing and prompt isolation needs to be developed for more effective reduction and protecting the livelihoods allowing to further relax the lockdown measures. Key messages There is need for the local government to consider a strategic easing of the lockdown for protecting the rights of the most affected population. As the transmission rates are low, the easing of lockdown can be benefited from improved testing and prompt isolation.
