The novel coronavirus SARS-CoV-2 has paralyzed our societies, leading to self-isolation and quarantine for several days. As the 10th most populated country in the world, Mexico is on a major threat by COVID-19 due to the limitations of intensive care capacities, about 1.5 hospital beds for every 1,000 citizens. In this paper, we characterize the COVID-19 pandemic in Mexico and projected different scenarios to evaluate sharp or gradual quarantine lifting strategies. Mexican government relaxed strict social distancing regulations on June 1, 2020, deriving to pandemic data with large fluctuations and uncertainties of the tendency of the pandemic in Mexico. Our results suggest that lifting social confinement must be gradually sparse while maintaining a decentralized region strategy among the Mexican states. To substantially lower the number of infections, simulations highlight that a fraction of the population that represents the elderly should remain in social confinement (approximately 11.3% of the population); a fraction of the population that represents the confined working class (roughly 27% of the population) must gradually return in at least four parts in consecutive months; and to the last a fraction of the population that assumes the return of students to schools (about 21.7%). As the epidemic progresses, deconfinement strategies need to be continuously re-adjusting with the new pandemic data. All mathematical models, including ours, are only a possibility of many of the future, however, the different scenarios that were developed here highlight that a gradual decentralized region deconfinement with a significant increase in healthcare capacities is paramount to avoid a high death toll in Mexico.

ABSTRACTThe novel coronavirus SARS-CoV-2 has paralysed our societies, leading to self isolation and quarantine for several days. As the 10th most populated country in the world, Mexico is on a major threat by COVID-19 due to the limitations of intensive care capacities, and a total of about 1.5 hospital beds for every 1000 citizens. In this paper, we projected different scenarios to evaluate sharp or gradual quarantine lifting strategies, however, even in the hypothetical scenario that Mexico would continue with full confinement, hospitals would be reaching the maximum capacity of hospital bed occupancy. Mexican government is planning to relax the strict social distancing regulations on 1 June 2020, however, epidemic rebound risks are latent.Our results suggest that lifting social confinement needs to be gradually sparse while maintaining a decentralized region strategy among the Mexican states. To substantially lower the number of infections, predictions highlight that the elderly should remain in social confinement (approximately 11.3% of the population); the confined working class (roughly 27% of the population) must gradually return in at least four parts in consecutive months; and to the last the return of students to schools (about 21.7%). As the epidemic progresses, de-confinement strategies need to be continuously re-adjusting with the new pandemic data. Assuming the most optimistic scenario by our predictions, the smallest number of new COVID-19 cases, Mexico would require at least a 3 fold increase in hospital capacities dedicated for COVID-19. Furthermore, to observe the real dimension of the epidemic, Mexico would need to increase to at least 18 samples per 1000 people, currently is only 0.6 per 1000.All mathematical models, including ours, are only a possibility of many of the future, however, the different scenarios that were developed here highlight that a gradual decentralized region de-confinement with a significant increase in healthcare capacities is paramount to avoid a high death toll in Mexico.

In 2019, the world experienced a global public health concern when the novel coronavirus originated from China and affected around fifty-seven thousand people around the world by March 2020. The quick rise in the number of cases and the death toll overwhelmed the scientific and medical community. While all the focus was driven towards finding the epidemiology, the treatment and the management, the mental health aspect of the quarantine was being overlooked. The purpose of this review is to create awareness about the long-term consequences of quarantine, with the focus on the elderly community in Pakistan.

The sudden outbreak of 2019 novel coronavirus (2019-nCoV) caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) originated from Wuhan, China. SARS-CoV-2 causes severe respiratory illness and becomes a major threat for humanity. Recently the entire scientist, researchers and physicians all over the countries focused to find the treatment of this pandemic disease. Numerous drugs and or vaccines have been trialed for prevention and treatment against 2019-nCoV but no therapy has been shown effective to date. Currently, numerous vaccines are under clinical investigation and mRNA-1273 vaccine (LNP- encapsulated mRNA vaccine encoding S protein) from Moderna is ahead. Although chloroquine, hydroxychloroquine, remdesivir and many other drugs had recommended against SARS-CoV-2, but still they are not the guarantee treatment of COVID-19. Recently, India, America, Russia and China introduced vaccines against COVID-19 in the market, however assurance of their 100% effectiveness are doubtful. The speed of daily new cases threatens the world and urges the scientist to crack this pandemic condition. KEYWORDS: 2019-nCoV; Chloroquine; COVID-19; Moderna; Respiratory disease; Remdesivir.

Epidemiology is the technique used to detect the origins of health outcomes and diseases in inhabitants. In epidemiology, the patient, the individual, and community are viewed mutually. Epidemiology is not only the analysis of health in inhabitants; it also includes applying the information enlarged by the analysis of public-based practice. In case of medicine, the practice of epidemiology is both an art and science. Currently, COVID-19 has spread all around the world. It is basically a severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Through the binding of receptor in gene region of its spike protein, ACE2 is bounded by corona virus. In this chapter, the authors summarized the epidemiological characteristics, clinical features, diagnosis, and treatment prognosis of COVID-19. A complete consideration will help to control the disease.

Abstract Background: Since the outbreak of the novel coronavirus disease (COVID-19), the fever outpatient clinic has been open in Shanghai East Hospital (SEH). We analyzed the data for all 4,699 patients from SEH and the 27 confirmed COVID-19 cases among them to determine the clinical and epidemiological characteristics of confirmed COVID-19 cases identified in the SEH. Methods: Data were collected for patients who visited the fever outpatient clinic in the SEH between January 23 and April 30, 2020. We compared the characteristics of confirmed cases, including age, occupation, area, symptoms, laboratory results, and computed tomography (CT) scans, by month.Results: By April 30, 4,699 patients had visited the fever outpatient clinic of the SEH; of those, 27 (0.57%) were confirmed COVID-19 cases. Among the confirmed domestic cases identified between January and February, four of five were from Wuhan, Hubei. Following the spread of the epidemic to other parts of the world, all confirmed cases identified in March–April were cases of individuals who were returning from abroad, mainly Chinese students living abroad. Further, all cases were from outside Shanghai, and no local residents were diagnosed in the clinic. Symptoms, laboratory tests, and CT scans were consistent with previous literature reports of positive COVID-19 cases. Conclusions: Given the necessity to control the spread of this epidemic domestically and abroad, the focus of COVID-19 prevention and control has shifted. In Shanghai, measures taken to prevent COVID-19 spread were very successful. Early isolation and quarantine are necessary and effective measures.

Myths are widely dispersed but false ideologies or misconceptions. With the thousands of deaths recorded daily and the negative toll of the novel coronavirus disease (COVID-19) on public health, national economy, and human interaction, it remains surprising how people are still being swayed by conspiracy theories. Due to the novelty of the disease, the quest for an answer, what works, and what does not work gave room for the propagation of misinformation, especially on social media. Identifying and debunking myths is very important in managing disease outbreak, since myths can negatively influence the response of people to preventive and containment strategies. Major proponents of COVID-19 myths have promoted their falsehood on the guise that it is a biological weapon engineered to control the world population. Others have also falsely claimed the use of antibiotics or other antiviral drugs in the treatment of COVID-19 and that COVID-19 is no worse than the common flu or it is just the disease of the elderly. This has promoted refusal to take up the COVID-19 vaccine and increased non-adherence to the preventive guidelines. Myths have been a major stumbling block to curtailing the menace of COVID-19. All hands must be on deck to fight this.

According to the World Health Organisation, until 16 June, 2020, the number of confirmed and notified cases of COVID-19 has already exceeded 7.9 million with approximately 434 thousand deaths worldwide. This research aimed to find repurposing antagonists, that may inhibit the activity of the main protease (Mpro) of the SARS-CoV-2 virus, as well as partially modulate the ACE2 receptors largely found in lung cells, and reduce viral replication by inhibiting Nsp12 RNA polymerase. Docking molecular simulations were performed among a total of 60 structures, most of all, published in the literature against the novel coronavirus. The theoretical results indicated that, in comparative terms, paritaprevir, ivermectin, ledipasvir, and simeprevir, are among the most theoretical promising drugs in remission of symptoms from the disease. Furthermore, also corroborate indinavir to the high modulation in viral receptors. The second group of promising drugs includes remdesivir and azithromycin. The repurposing drugs HCQ and chloroquine were not effective in comparative terms to other drugs, as monotherapies, against SARS-CoV-2 infection.

Currently, the world is facing a health and socioeconomic crisis caused by the novel coronavirus disease COVID-19. On 11 March 2020, the World Health Organization (WHO) has declared this disease as a pandemic. The condition (COVID-19) is an infectious disorder triggered by a newly discovered severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2. Most of the COVID-19 infected patients will experience mild to moderate respiratory symptoms and recover without any unique therapy. Assessment of the clinical and epidemiological characteristics of SARS-CoV-2 cases suggests the infected patients will not be contagious until the onset of severe symptoms and affects the other organs. Well-differentiated cells of apical airway epithelia communicating with ACE2 were promptly infected to SARS-CoV-2 virus. But the expression of ACE 2 in poorly differentiated epithelia facilitated SARS spike (S) protein-pseudo typed virus entry and it is replicated in polarized epithelia and especially exited via the apical surface. Limiting the transmission of COVID-19 infection & its prevention can be regarded as a hierarchy of controls. In this article, we briefly discuss the most recent advances in respect to aetiology, pathogenesis and clinical progression of the disease COVID-19.

In December 2019, a unique coronavirus infection, SARS-CoV-2, was first identified in the province of Wuhan in China. Since then, it spread rapidly all over the world and has been responsible for a large number of morbidity and mortality among humans. According to a latest study, Diabetes mellitus, heart diseases, Hypertension etc. are being considered important risk factors for the development of this infection and is also associated with unfavorable outcomes in these patients. There is little evidence concerning the trail back of these patients possibly because of a small number of participants and people who experienced primary composite outcomes (such as admission in the ICU, usage of machine-driven ventilation or even fatality of these patients). Until now, there are no academic findings that have proven independent prognostic value of diabetes on death in the novel Coronavirus patients. However, there are several conjectures linking Diabetes with the impact as well as progression of COVID-19 in these patients. The aim of this review is to acknowledge about the association amongst Diabetes and the novel Coronavirus and the result of the infection in such patients.

: The novel coronavirus disease-19 (COVID-19), a global pandemic that emerged from Wuhan, China has today travelled all around the world, so far 216 countries or territories with 21,732,472 people infected and 770,866 deaths globally (as per WHO COVID-19 update dated August 18, 2020). Continuous efforts are being made to repurpose the existing drugs and develop vaccines for combating this infection. Despite, to date, no certified antiviral treatment or vaccine prevails. Although, few candidates have displayed their efficacy in in vitro studies and are being repurposed for COVID-19 treatment. This article summarizes synthetic and semi-synthetic compounds displaying potent activity in their clinical experiences or studies against COVID-19 and also focuses on mode of action of drugs being repositioned against COVID-19.
