At the turn of the nineteenth century, yellow fever (YF) was considered the most dangerous infectious disease with high case fatality. Subsequent, mass vaccination campaigns coupled with widespread elimination of the YF mosquito vector significantly decreased YF cases and reduced outbreaks to the tropical and subtropical forested regions of Africa and South America. However, recent (2016) large outbreaks in Angola, Democratic Republic of Congo (DRC), and South-Eastern Brazil, where previously had been demarcated as low-risk regions, have highlighted the possibility of a rapidly changing epidemiology and the potential re-emergence of yellow fever virus (YFV). Furthermore, the first-ever importation of YFV into Asia has highlighted the potential fear of YFV emerging as a global threat. In this review, we describe the changing epidemiology of YF outbreaks, and highlight the use of public health policies, therapeutics, and vaccination as tools to help eliminate future YFV outbreaks.The spread of coronavirus disease, 2019, has affected several countries in the world including Asian countries. The occurrences of COVID infections are uneven across countries and the same is determined by socioeconomic situations prevailing in the countries besides the preparedness and management. The paper is an attempt to empirically examine the socioeconomic determinants of the occurrence of COVID in Asian countries considering the data as of June 18, 2020, for 42 Asian countries. A multiple regression analysis in a cross-sectional framework is specified and ordinary least square (OLS) technique with heteroscedasticity corrected robust standard error is employed to obtain regression coefficients. Explanatory variables that are highly collinear have been dropped from the analysis. The findings of the study show a positive significant association of per capita gross national income and net migration with the incidence of total COVID-19 cases and daily new cases. The size of net migration emerged to be a potegies. The countries having larger net migration and poverty ratio need to evolve comprehensive and inclusive strategies for testing, tracing, and massive awareness for sanitary practices, social distancing, and following government regulation for management of COVID-19, besides appropriate food security measures and free provision of sanitary kits for vulnerable section.The unpredictable dynamics of COVID-19 and policies surrounding its management has triggered severe debates and discussions among every section of society. There have been similarities as well as differences in opinions regarding spread of the disease, the lockdown, its implementations and impacts. This qualitative study attempts to identify and understand the emerging pattern within the opinions of 16 social scientists from eminent institutes with rich socioeconomic and demographic research experience. Several key themes emerged from this study. While it is opined that the lockdown initially slowed down the spread of virus among Indian population, it continues to surge exponentially. Economy faced extreme hardship because of this extensive and abrupt national lockdown. State-wise variation in the COVID-19 scenario is noticed and the reason is attributed to the strictness of implementation of the lockdown by the respective state governments. However, a lockdown in phases is suggested that could have averted the economic crisis. Small businesses were the hardest hit. Migrant workers were not given deserved attention and support in terms of their travel to their natives, health or financial sustenance during the lockdown. The bailout has not been timely and enough thereby creating a group of new poor. From the opinions it emerges that the policy measures intended to revive back the micro, small and medium scale enterprises may not bring short-term solution pertaining to the labor crisis. Relaxation of lockdown also calls for stringent awareness generation among general population about health and hygiene maintenance to avoid further spread of COVID-19.The research develops a theoretical model that highlights the determinants of adoption of online teaching at the time of the outbreak of COVID 19. Empirical data was gathered from 643 school teachers by means of an online survey. The proposed conceptual framework was investigated empirically by means of confirmatory factor analysis (CFA) and structural equation modelling (SEM). The findings of the study revealed performance expectancy, and facilitating conditions had a positive impact on behavioural intention as well as attitude. However, effort expectancy failed to drive teachers' adoption to online teaching. On the other hand, social influence had insignificant relationship with attitude but significant relationship with behavioural intention. Attitude had a significant impact on behavioural intention as well as actual use. This study contributes to the literature by presenting and validating a theory-driven framework that accentuates the factors influencing online teaching during outbreak of a pandemic.Coronavirus (COVID-19) pandemic has created an unprecedented loss and disruptions over all across the world. From developed to developing, no country has been spared from its brunt. In this paper, we have analyzed the implications of COVID-19 on the economy and society of India so far. Sodium butyrate An impact assessment on the basis of available lietrature is made on all the three sectors-primary, secondary and service sector along with the impact on migrants, health, poverty, job losses, informal sector, environment, and so forth. The all sectors of the economy has been disproportionately affected and even within a sector, there is a disproportionate loss. The societal impacts are dire too with job losses, mental illness, increased domestic violence, and so forth. Some positive effects can be seen in terms of improved air quality, water quality, wildlife but the sustainability of such impact is conditional upon post-COVID and people's habits and future policies related to the environment.Background Tumor mutation burden (TMB) is considered as a novel biomarker of response to immunotherapy and correlated with survival outcomes in various malignancies. Here, TMB-related genes (TRGs) expression signatures were constructed to investigate the association between TMB and prognosis in epithelial ovarian cancer (EOC), and the potential mechanism in immunoregulation was also explored. Methods Based on somatic mutation data of 436 EOC samples from The Cancer Genome Atlas database, we examined the relationship between TMB level and overall survival (OS), as well as disease-free survival (DFS). Next, the TRGs signatures were constructed and validated. Differential abundance of immune cell infiltration, expression levels of immunomodulators and functional enrichment in high- and low-risk groups were also analyzed. Results Higher TMB level revealed better OS and DFS, and correlated with earlier clinical stages in EOCs (P = 2.796e-04). The OS-related prognostic model constructed based on seven TRGs (B3GALT1, LIN7B, ANGPT2, D2HGDH, TAF13, PFDN4 and DNAJC19) significantly stratified EOC patients into high- and low-risk groups (P less then 0.
