At this moment, public health authorities, physicians and scientists around the world are struggling to cope with a severe and rapidly spreading new disease in humans called severe acute respiratory syndrome, or SARS. According to World Health Organisation (WHO) this appears to be the first severe and easily transmissible new disease to emerge in the 21st century. Though much about the disease remains poorly understood, including the details of the causative virus, we do know that it has features that allow it to spread rapidly along international air travel routes. As of 10 May 2003, a cumulative 7296 probable SARS cases with 526 deaths have been reported from 30 countries on three continents (WHO, ProMED). In the past week, more than 1000 new probable cases and 96 deaths were reported globally. This represents an increase of 119 new cases and 8 new deaths compared with 9 May 2003 (China (85), Taiwan (23), and Hong Kong (7) represented the overwhelming majority, with one additional case each reported from France, Malaysia, Singapore, and the United States). Only in China, as of 10 May 2003 (WHO) total of 4884 with 235 deaths have been reported. Some outbreaks have reassuring features.

SARS or severe acute respiratory syndrome is a term used to describe a serious respiratory illness, which has recently been reported in parts of the world and has spread widely over the past G months. At this moment, public health authorities, physicians and scientists around the world are struggling to cope with this rapidly spreading multicountry outbreak of an unexplained new disease in humans. This appears to be the first severe and easily transmissible disease to emerge in the 21st century. Though much about the syndrome remains poorly understood, including the exact identity of the causative virus, the indications are that the outbreak is otherwise being contained.

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.

Salt is the oldest preservative used for food. But the excessive consume of salt is at the origin of blood hypertension, a problem responsible for a huge number of human diseases and deaths. As a consequence, the level of salt added in processed food has to diminish progressively. At the end of 2009, the Public Health Authorities from 29 Romanian counties reported results from the salt analysis of 1321 samples of different foods. The highest levels of salt were found in “telemea” cheese and the significant salt content in other widely consumed food underlined the necessity for a joined effort in order to bring down salt and to comply with the World Health Organization target

Background: In January 2020 the world health organisation (WHO) declared the outbreak of a new coronavirus disease, COVID-19, to be a public health emergency of international concern. WHO stated that there is a high risk of COVID-19 spreading to other countries around the world. In March 2020, WHO made the assessment that COVID-19 can be characterized as a pandemic. WHO and public health authorities around the world are acting to contain the COVID-19 outbreak. To assess the level of COVID-19 pandemic stress before and after vaccination and to find out the association of COVID-19 pandemic stress scores with selected demographic variables of B. Sc nursing students. Methods: A pre-experimental study was done on 150 Nursing students in selected various nursing colleges at Meerut. The convenience sampling technique was used. Nursing Students stress were assessed by using standardized Sheldon Cohen modified stress scale. Results: The result showed that mean score before and after vaccination of stress with SD for was (0.237) nursing students was 13.20±2.202, 6.20±1.202 and correlation of patient with COVID-19 suggesting a negative significant correlation between the stress ‘r’ value was less than table value (0.273) with df 149. At (0.05) level of significance. Conclusions: there was no significant association between level of stress and demographic variables among Nursing students. It is inferred that there is moderate to severe level of stress before and moderate to mild level of stress after vaccination.

Severe acute respiratory syndrome, caused by SARS-CoV-2 disease (COVID-19), was first reported in China, and has laid the entire globe at a standstill, with an uncertain future, and a possible economic disaster. The World Health Organization (WHO), on March 11th 2020, avowed COVID-19 a pandemic considering its global pervasiveness. The multi-dimensional challenges include the combat with present available treatment options while simultaneously hastening scientific research for the development of definitive therapeutics and vaccine for this pandemic. The research advancement related to earlier epidemics of severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS) by the same coronavirus family provides the understanding of basic and clinical virology, pathogenesis and therapeutics of SARS-CoV-2. The dearth of definitive therapeutics and vaccine renders COVID-19 pandemic a public health challenge globally. This comprehensive review of virology, pathogenesis, and management will abet quarters of public health authorities and medical fraternity to better understand COVID-19.

This study aims to describe Facebook users’ beliefs toward physical distancing measures implemented during the Coronavirus disease (COVID-19) pandemic using the key constructs of the health belief model. A combination of rule-based filtering and manual classification methods was used to classify user comments on COVID-19 Facebook posts of three public health authorities: Centers for Disease Control and Prevention of the United States, Public Health England, and Ministry of Health, Singapore. A total of 104,304 comments were analyzed for posts published between 1 January, 2020, and 31 March, 2020, along with COVID-19 cases and deaths count data from the three countries. Findings indicate that the perceived benefits of physical distancing measures ( n = 3,463; 3.3%) was three times higher than perceived barriers ( n = 1,062; 1.0%). Perceived susceptibility to COVID-19 ( n = 2,934; 2.8%) was higher compared with perceived severity ( n = 2,081; 2.0%). Although susceptibility aspects of physical distancing were discussed more often at the start of the year, mentions on the benefits of intervention emerged stronger toward the end of the analysis period, highlighting the shift in beliefs. The health belief model is useful for understanding Facebook users’ beliefs at a basic level, and it provides a scope for further improvement.

BACKGROUND Misinformation about COVID-19 has presented challenges to public health authorities during pandemics. Understanding the prevalence and type of misinformation across contexts offers a way to understand the discourse around COVID-19 while informing potential countermeasures. OBJECTIVE The aim of the study was to study COVID-19 content on two prominent microblogging platform, Twitter, based in the United States, and Sina Weibo, based in China, and compare the content and relative prevalence of misinformation to better understand public discourse of public health issues across social media and cultural contexts. METHODS A total of 3,579,575 posts were scraped from both Weibo and Twitter, focusing on content from January 30th, 2020, when the World Health Organization (WHO) declared COVID-19 a “Public Health Emergency of International Concern” and February 6th, 2020. A 1% random sample of tweets that contained both the English keywords “coronavirus” and “covid-19” and the equivalent Chinese characters was extracted and analyzed based on changes in the frequencies of keywords and hashtags. Misinformation on each platform was compared by manually coding and comparing posts using the World Health Organization fact-check page to adjudicate accuracy of content. RESULTS Both platforms posted about the outbreak and transmission but posts on Sina Weibo were less likely to reference controversial topics such as the World Health Organization and death and more likely to cite themes of resisting, fighting, and cheering against the coronavirus. Misinformation constituted 1.1% of Twitter content and 0.3% of Weibo content. CONCLUSIONS Quantitative and qualitative analysis of content on both platforms points to cross-platform differences in public discourse surrounding the pandemic and informs potential countermeasures for online misinformation.

ABSTRACTCOVID-19 epidemic is declared as the public health emergency of international concern by the World Health Organisation in the second week of March 2020. This disease originated from China in December 2019 has already caused havoc around the world, including India. The first case in India was reported on 30th January 2020, with the cases crossing 6000 on the day paper was written. Complete lockdown of the nation for 21 days and immediate isolation of infected cases are the proactive steps taken by the authorities. For a better understanding of the evolution of COVID-19 in the country, Susceptible-Infectious-Quarantined-Recovered (SIQR) model is used in this paper. It is predicted that actual infectious population is ten times the reported positive case (quarantined) in the country. Also, a single case can infect 1.55 more individuals of the population. Epidemic doubling time is estimated to be around 4.1 days. All indicators are compared with Brazil and Italy as well. SIQR model has also predicted that India will see the peak with 22,000 active cases during the last week of April followed by reduction in active cases. It may take complete July for India to get over with COVID-19.

This research article critically interrogates the implications and unintended consequences of the World Health Organization’s purported elimination of leprosy as a public health problem. I explore how leprosy has been portrayed (for nearly a century) as something from the past, recalcitrantly lingering on into the present, but surely about to be gone—a temporal framing I call the ‘grammar of leprosy’. I recount the experiences of Daniel, my interlocutor in Tanzania, whose existence became a problem for his doctors. This problem they ultimately resolved by fabricating negative test results in order to record what they already knew: leprosy had been eliminated. I also analyse how researchers working for Novartis (the supplier of leprosy’s cure) continue to push for an always imminent ‘elimination’, while field researchers repeatedly caution about the potential problems of this approach. Finally, I reveal how the grammar of leprosy operates through a complex set of temporal politics, pulling into its orbit and being enabled by multiple interwoven temporalities. I conclude that—due to this grammar, the impossible subjects it produces, and the temporal politics through which it operates—leprosy elimination campaigns may have dire consequences for the lives of people with leprosy today, impeding rather than enabling treatment.

To the EditorNovel Coronavirus disease (COVID-19) was first notified in December 2019 from Wuhan, China. Now, it has spread rapidly and has been declared a pandemic affecting over 200 countries with widespread morbidity and mortality. It has been postulated that the most vulnerable population are the elderly, people living in crowded areas, children and immune-compromised individuals, such as people living with human immunodeficiency virus (HIV). The correlation of tuberculosis (TB), HIV and malnutrition are well documented and hence, people with tuberculosis should be considered as special population in this pandemic. TB is an ancient disease among humans recorded as far back as seventy thousand years which was declared a global public health emergency in 1993 by the World Health Organisation (WHO). India has the highest TB burden in the world.
