The prevention of disease transmission is an effective cost-strategy in controlling COVID-19. The scenario of the control of COVID-19 in Samarinda City consists of 3 phases, namely initial, advanced, and recovery. The outcome of the advanced phase is flattening the transmission curve of the COVID-19 pandemic, with an increased proportion of patients in recovery, and an increased culture of preventing disease transmission in society. This study aimed at knowing the influence of the understanding of COVID-19 infographics on the efforts to prevent COVID-19 transmission at the advanced phase. A survey was conducted via social media from April 21st to April 30th, 2020. The preventive actions for the disease transmission as the dependent variable in this study were social distancing, wearing a mask, washing hands, and efforts to enhance the body’s immunity, while the independent variable was the understanding of COVID-19 infographics updated daily. The results of the study showed that the proportion of the population who understood the infographics well was 79.5%, the community participation in practicing social distancing (81.6%), wearing a mask  (50.9%), washing hands as frequently as possible (74.3%), and the efforts to strengthen the body’s immune system (73.6%) with a consistency level of 55.12%. The lowest rate for the activity of social distancing was visiting elders or the people suffering from comorbidities with 54.71%. A good understanding of infographics could increase adherence to the recommendations of social distancing. The implementation of social distancing, wearing a mask, washing hands as frequently as possible, and the efforts to improve the body’s immune system need to be done consistently to prevent the COVID-19 transmission and as a result, the potential transmission could be minimized to optimize the recovery phase and anticipate the possible second wave of the COVID-19 pandemic.

ABSTRACTBackgroundAcross the U.S., various social distancing measures were implemented to control COVID-19 pandemic. However, there is uncertainty in the effectiveness of such measures for specific regions with varying population demographics and different levels of adherence to social distancing. The objective of this paper is to determine the impact of social distancing measures in unique regions.MethodsWe developed COVid-19 Agent-based simulation Model (COVAM), an agent-based simulation model (ABM) that represents the social network and interactions among the people in a region considering population demographics, limited testing availability, imported infections from outside of the region, asymptomatic disease transmission, and adherence to social distancing measures. We adopted COVAM to represent COVID-19-associated events in Dane County, Wisconsin, Milwaukee metropolitan area, and New York City (NYC). We used COVAM to evaluate the impact of three different aspects of social distancing: 1) Adherence to social distancing measures; 2) timing of implementing social distancing; and 3) timing of easing social distancing.ResultsWe found that the timing of social distancing and adherence level had a major effect on COVID-19 occurrence. For example, in NYC, implementing social distancing measures on March 5, 2020 instead of March 12, 2020 would have reduced the total number of confirmed cases from 191,984 to 43,968 as of May 30, whereas a 1-week delay in implementing such measures could have increased the number of confirmed cases to 1,299,420. Easing social distancing measures on June 1, 2020 instead of June 15, 2020 in NYC would increase the total number of confirmed cases from 275,587 to 379,858 as of July 31.ConclusionThe timing of implementing social distancing measures, adherence to the measures, and timing of their easing have major effects on the number of COVID-19 cases.Primary Funding SourceNational Institute of Allergy and Infectious Diseases Institute

AbstractIn 2020, the world experienced its very first pandemic of the globalized era. A novel coronavirus, SARS-CoV-2, is the causative agent of severe pneumonia and has rapidly spread through many nations, crashing health systems and leading a large number of people to death. In Brazil, the emergence of local epidemics in major metropolitan areas has always been a concern. In a vast and heterogeneous country, with regional disparities and climate diversity, several factors can modulate the dynamics of COVID-19. What should be the scenario for inner Brazil, and what can we do to control infection transmission in each of these locations? Here, a mathematical model is proposed to simulate disease transmission among individuals in several scenarios, differing by abiotic factors, social-economic factors, and effectiveness of mitigation strategies. The disease control relies on keeping all individuals’ social distancing and detecting, followed by isolating, infected ones. The model reinforces social distancing as the most efficient method to control disease transmission. Moreover, it also shows that improving the detection and isolation of infected individuals can loosen this mitigation strategy. Finally, the effectiveness of control may be different across the country, and understanding it can help set up public health strategies.

AbstractHow does social distancing affect the reach of an epidemic in social networks? We present Monte Carlo simulation results of a susceptible–infected–removed with social distancing model. The key feature of the model is that individuals are limited in the number of acquaintances that they can interact with, thereby constraining disease transmission to an infectious subnetwork of the original social network. While increased social distancing typically reduces the spread of an infectious disease, the magnitude varies greatly depending on the topology of the network, indicating the need for policies that are network dependent. Our results also reveal the importance of coordinating policies at the ‘global’ level. In particular, the public health benefits from social distancing to a group (e.g. a country) may be completely undone if that group maintains connections with outside groups that are not following suit.

Innate Lymphocytes

Bats are reservoirs of a large number of viruses of global public health significance, including the ancestral virus for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the causative agent of coronavirus disease 2019 (COVID-19). Although bats are natural carriers of multiple pathogenic viruses, they rarely display signs of disease. Recent insights suggest that bats have a more balanced host defense and tolerance system to viral infections that may be linked to the evolutionary adaptation to powered flight. Therefore, a deeper understanding of bat immune system may provide intervention strategies to prevent zoonotic disease transmission and to identify new therapeutic targets. Similar to other eutherian mammals, bats have both innate and adaptive immune systems that have evolved to detect and respond to invading pathogens. Bridging these two systems are innate lymphocytes, which are highly abundant within circulation and barrier tissues. These cells share the characteristics of both innate and adaptive immune cells and are poised to mount rapid effector responses. They are ideally suited as the first line of defense against early stages of viral infections. Here, we will focus on the current knowledge of innate lymphocytes in bats, their function, and their potential role in host–pathogen interactions. Moreover, given that studies into bat immune systems are often hindered by a lack of bat-specific research tools, we will discuss strategies that may aid future research in bat immunity, including the potential use of organoid models to delineate the interplay between innate lymphocytes, bat viruses, and host tolerance.

Corona virus Disease 2019 (COVID-19) is a severe acute respiratory infection caused by corona virus-2 (SARS-CoV-2). It originated from Wuhan city of China in December 2019 and spread like a wild fire to the entire globe and was declared as global pandemic by WHO on March 11, 2020. With no available cure and vaccine, this disease has taken a mammoth toll on the human life; therefore, SMS (‘Social Distancing’, use of ‘Mask’ and regular hand washing with ‘Soap’) has emerged as a sole tool to prevent its spread. The Indian government declared the first lockdown from March 25th 2020 with subsequent second, third and fourth lockdowns up to 31st March 2020 to decrease the disease transmission and flatten the disease transmission curve. Aligarh Muslim University is one of the prestigious central and residential universities in India. It is located in Aligarh district adjoining national capital region. The university has an attached tertiary care ‘Jawaharlal Nehru Medical College Hospital’. This narrative review discusses the various steps and procedures taken up by the university and hospital administration, other functionaries, faculty members and doctors in tackling the serious pandemic until 22nd June 2020. The proactive role of administration, dedication and hard work of health care professionals and innovation of some academicians has given a new vista of opportunities to tackle this global health pandemic. The recovery rate of coronavirus patients at AMU hospital is recorded as 71.9%, which is much higher than national average recovery rate (56%). Thus, AMU model gives some positive insights to fight the current global pandemic. Bangladesh Journal of Medical Science Vol.19(0) 2020 p. S 28-S 35

The Impact

The continued spread of COVID-19 suggests a significant possibility of reimposing the lockdowns and stricter social distancing similar to the early phase of pandemic control. We present a dynamic model to quantify the impact of isolation for the contagion curves. The model is calibrated to the COVID-19 outbreak in Spain to study the effects of the isolation enforcement following the declaration of the state of alarm (14 March 2020). The simulations indicate that both the timing and the intensity of the isolation enforcement are crucial for the COVID-19 spread. For example, a 4-day earlier intervention for social distancing would have reduced the number of COVID-19 infected people by 67%. The model also informs us that the isolation enforcement does not delay the peak day of the epidemic but slows down its end. When relaxing social distancing, a reduction of the contagion probability (with the generalization of preventive actions, such as face mask wearing and hands sanitizing) is needed to overcome the effect of a rise in the number of interpersonal encounters. We report a threshold level for the contagion pace to avoid a second COVID-19 outbreak in Spain.

In December 2019 an outbreak of COVID19 occurred which is a severe acute respiratory disorder. Many succumbed to this global pandemic and many are still fighting the after effect of it. The virus directly affects the immune system especially of lungs. Therefore, the people who already have compromised immunity are at the very risk. The first symptoms to appear in COVID19 patients are ageusia and anosmia while treating the COVID19 patient’s certain practices are followed which aid in rapid oral health deterioration like oxygen mask, ventilators, heavy dose of medicines. Certain medicines used in treatment also precipitate poor oral health like bleeding gums, oral ulceration and dry mouth are the most common oral health problems faced after COVID19 recovery. COVID directly affects the immune system thereby making way for opportunistic infections like mucormycosis. Mucormycosis offers a severe burden on oral and general health affecting the standard of living and cause death in severe cases. Sinusitis, Periodontitis, black staining across the bridge of nose and sinus, localized discomfort and unbearable diplopia and refractive errors along with embolism and necrosis are seen in mucormycosis patients. Treatment of mucormycosis consists of surgery and replacement of lost structures Patients with compromised immunity need to take proper precautions during and after COVID.

Coronavirus 2019 (COVID-19) has been spreading across the globe in 2020 with most countries being affected significantly in terms of the number of infected cases, morbidity and mortality, as well as health care and economic burden. Currently the most important individual and community measures for curtailing disease transmission are social distancing, hand sanitization and wearing of masks in public. It is important to advocate wearing masks in an effective and balanced manner and dispense supportive scientific evidence as well as practical guidelines and information in the community. Till the event of mass vaccination for COVID being available, improving the awareness, compliance and acceptance of the people towards proper wearing of a face mask when in public places, can be the most effective way for several countries to control transmission of COVID.
