Extrapolated values of R(t) can be used in the model to make reliable forecasts, though under the assumption that measures for reducing infections are maintained. We have applied our model to more than 15 countries and the ongoing results are available on a web-based platform [1]. In this paper, we focus on the data for two exemplary countries, Italy and Germany, and show that the model is capable of reproducing the course of the epidemic in the past and forecasting its course for a period of four to five weeks with a reasonable numerical stability.We discussed anthroponotic cutaneous leishmania transmission in this article, due to its large effect on the community in the recent years. The mathematical model is developed for anthroponotic cutaneous leishmania transmission, and its qualitative behavior is taken under consideration. The threshold number R 0 of the model is derived using the next-generation method. In the disease-free case, local and global stability is carried out with the condition that R 0 will be less than one. The global stability at the disease-free equilibrium point has been derived by utilizing the Castillo-Chavez method. On the other hand, at the endemic equilibrium point, the local and global stability holds with some conditions, and R 0 is greater than unity. The global stability at the endemic equilibrium point is established with the help of a geometrical approach which is the generalization of Lyapunov theory, by using the third additive compound matrix. The sensitivity analysis of the threshold number with other parameters is also taken into account. Several graphs of important parameters are discussed in the last section.World Health Organization declared the novel coronavirus disease 2019 (COVID-19) outbreak to be a public health crisis of international concern. Further, it provided advice to the global community that countries should place strong measures to detect disease early, isolate and treat cases, trace contacts and promote "social distancing" measures commensurate with the risk. This study analyses the COVID-19 infection data from the top 15 affected countries in which we observed heterogeneous growth patterns of the virus. Hence, this paper applies multifractal formalism on COVID-19 data with the notion that country-specific infection rates follow a power law growth behaviour. According to the estimated generalized fractal dimension curves, the effects of drastic containment measures on the pandemic in India indicate that a significant reduction of the infection rate as its population is concern. Also, comparison results with other countries demonstrate that India has less death rate or more immunity against COVID-19.
  The discovery of SARS-CoV-2, the responsible virus for the Covid-19 epidemic, has sparked a global health concern with many countries affected.  https://www.selleckchem.com/products/piperaquine-phosphate.html  Developing models that can interpret the epidemic and give common trend parameters are useful for prediction purposes by other countries that are at an earlier phase of the epidemic; it is also useful for future planning against viral respiratory diseases. One model is developed to interpret the fast-growth phase of the epidemic and another model for an interpretation of the entire data set. Both models agree reasonably with the data. It is shown by the first model that during the fast phase, the number of new infected cases depends on the total number of cases by a power-law relation with a scaling exponent equal to 0.82. The second model gives a duplication time in the range 1-3days early in the start of the epidemic, and another parameter (
   = 0.1-0.5) that deviates the progress of the epidemic from an exponential growth. Our models may be used for data interpretation and for guiding predictions regarding this disease, e.g., the onset of the maximum in the number of new cases.
 
  According to a national representative survey, 19.9% of the German population describe various adverse effects on personal health upon exposure to fragranced consumer products. This study investigates whether these fragrance-sensitive persons have a higher risk awareness compared to the general public, whether they show a different safety behavior concerning fragrances and whether they reduce exposure and hence risk.
 
  The presence of fragrances can have a major impact on the participation in public activities. Half of the fragrance-sensitive persons have ever been prevented from going to some place to avoid exposure to fragrances. More than half of them prefer fragrance-free alternatives (products, laundry, hotels, airplanes, health care facilities, or workplaces), while there are also fragrance-sensitive individuals, who indicate to prefer fragranced products and spaces. Half of fragrance-sensitive persons use perfumes to feel themselves more attractive. Furthermore, there is a large number of persons whoonance, confirmation bias and the inadequacy of the deficit model in risk management. The issue of adverse health effects associated with fragrances has reached a dimension, which requires immediate action The results of this study are strong supporting arguments in favor of fragrance-free policies.
 The high prevalence of persons who correlate their health effects with exposure to fragrances shows that existing risk communication instruments are too weak, even for people who are aware of a risk, like fragrance-sensitive persons. The data substantiate how important it is to respect cognitive dissonance, confirmation bias and the inadequacy of the deficit model in risk management. The issue of adverse health effects associated with fragrances has reached a dimension, which requires immediate action The results of this study are strong supporting arguments in favor of fragrance-free policies.This editorial considers the persisting importance of rhetoric and equity in health policy analysis, implementation, and outcomes. It argues that employing social determinants of health, and intersectional and rhetorical frames, can improve life and health outcomes, as measured by morbidity and mortality. The pertinence of these frames with regard to the crises brought on by the COVID-19 pandemic is discussed, and the plan for a special issue on disparties and COVID-19 is announced.
