Vector-borne diseases pose a major public health threat. Combined, these diseases contribute significantly to illness and mortality worldwide and have an adverse impact on development and economic growth of nations. Public health stakeholders seeking to control and prevent these diseases are confronted with a myriad of challenges. Some of these difficulties are related to the nature of the data, the uncertainty of disease dynamics, and volatility of human-environment interactions. Visualization tools are capable of ameliorating some of these challenges. In this paper, the authors demonstrate how interactive visualizations can support stakeholders' decision-making tasks. In particular, they present a visualization tool they created that can support control efforts related to the recent Zika outbreak in Brazil.

The impact of vector-borne diseases on developing nations is significant. Currently, the uncertainty of disease dynamics, volatility of human-environment interactions, and competing objectives coupled with the nature of applicable data present obstacles to stakeholders charged with developing preventive, control, and treatment measures. As a result, notwithstanding numerous measures, vector-borne diseases persist and impede the growth of developing nations. Therefore, computational tools that can address these obstacles and serve as decision support tools to stakeholders are much needed. This chapter is meant to draw attention to interactive visualization tools that allow stakeholders to control the flow of information, manipulate visual representations, and perform analytical tasks. Through a discussion of the vector-borne disease situation and interactive visualization tools, the case for integrating these tools into public health practice in developing nations is made.

The search conducted on "The impact of global warming (GW) on the public health (PH) increasing the bacterial causing infectious diseases (IDs) performed by experiment: Vector-borne diseases (VBDs) insects, Taif, KSA", the experiment used ants (Taif Tapinoma sessile), prepared, arranged appropriate nests and adjusted the temperature at (20, 25, 30, 35, 40 and 45°C), for a week of each zone. It revealed the behaviour as (normal, semi-normal and ab-normal), the mean of mortality rates were between (0-53.3%). The bacterial contents measured by the turbidity indicated the presence of multiplication, were between (0.109-0.328). The bacterial growth degrees by sings were between (+ - +++++) and percent between (12-100%). Colony Forming Unit/ml (CFU/ml) confined between (1.8X102-15.0X102)/mL. Through this experiment it turned out the GW had a significant role on the PH, helped the proliferation of bacterial pathogens that caused IDS. The conclusion wiped from the experiment that the extent degrees of GW disadvantages on the PH. The PH workers must take the "Preventive Health Prophylaxis Measures" (PHPMs) to protect the individuals from IDs by eliminating the VBDs of various types, monitoring the immunological situation of individuals, provided the vaccinations of IDs and preparing for complete PHPMs against any changes in the PH.

Zika virus is a newly emergent mosquito-borne flavivirus. Once almost ignored epidemiologically, recent major outbreaks and links to neurological birth defects have focused attention on this neglected pathogen. We review the discovery, biology and symptomatology of Zika virus, what is known and not known about the mosquitoes that transmit the virus, conspiracy theories currently hampering control efforts, and potential avenues of Zika control. It is likely that Zika virus is here to stay in the Americas, so a thorough understanding of the complete epidemiological transmission cycle and potential effects on the human population will be critical for managing this new disease in the coming years.

Abstract Zika is a vector-borne viral disease transmitted to humans primarily by Aedes aegypti mosquitoes. The increased climate instability has contributed to the emergence of infections carried by mosquitoes like dengue, chikungunya and zika. While infection with the zika virus is not new, the recent epidemic of microcephaly in Brazil and other countries in South America resulting from the infection of pregnant women with the zika virus raise a number of serious public health concerns. These include the question of how climate change affects the range of zika vectors, what can we do to shorten the length of mosquito season, how and why the symptoms of zika infection have changed and what can be done to reduce the burden of human disease from this infection? Another important question that needs to be answered is what are the factors that caused the zika virus to leave the non-human primates and/or other mammals and invade the human population?

Oxidative Species

Abstract The control of pests and vector-borne diseases (VDBs) are considered public health issues Worldwide. Among the control techniques and pesticides used so far, photodynamic inactivation (PDI) has been shown as an eco-friendly, low cost, and efficient approach to eliminate pests and VDBs. PDI is characterized using a photosensitizing molecule, light and molecular oxygen (O2) resulting in production of reactive oxidative species which can promote the oxidation of biomolecules on pests and vectors. Herein, we review the past 51 years (1970–2021) regarding the use of photo pesticides, reporting the most important parameters for the protocol applied, the results obtained, and limitations. Moreover, we described the mechanism of action of the PDI, main classes of photopesticides used so far as well as the cell death mechanism resulting from the photodynamic action.

This book concerns the population biology of vector-borne diseases. Vector-borne diseases of people are a perennial challenge for public health. Although recent decades have enjoyed major declines in the incidence of diseases like malaria and onchocerciasis (river blindness), vector-borne diseases continue to claim the lives of more than 700,000 people per year and exact costs of tens of billions of dollars in expenses for control and through lost productivity (...

Change in environmental and socio-economic, emerging zoonotic diseases will be an increasing challenge for public health in Europe and in Macedonia also. The risks and consequences triggered by vector-borne diseases (VBD) for public health in Macedonia are just starting to emerge in public awareness. This is clearly shown by recent events such as spread of hemorrhagic fevers in Europe. The term “public health” in the scope of this chapter suggests re-conceptualization of public health by adapting the risk governance framework developed by the International Risk Governance Council (IRGC) for this purpose. The IRGC approach is distinguished from more classical risk governance approaches, inter alia, by an explicit inclusion of a systematic concern assessment. However, unfortunately, not all countries are adapted on this innovative public health model. This chapter shows results of a risk management study based on interview in depth with the officials regard public health risk, in frame of one health concept in the Republic of Macedonia.

Vector-borne diseases closely associated with the environment, such as leishmaniases, have been a usual argument about the deleterious impact of climate change on public health. From the biological point of view interaction of different variables has different and even conflicting effects on the survival of vectors and the probability transmission of pathogens. The results on ecoepidemiology of leishmaniasis in Argentina related to climate variables at different scales of space and time are presented. These studies showed that the changes in transmission due to change or increase in frequency and intensity of climatic instability were expressed through changes in the probability of vector-human reservoir effective contacts. These changes of contact in turn are modulated by both direct effects on the biology and ecology of the organisms involved, as by perceptions and changes in the behavior of the human communities at risk. Therefore, from the perspective of public health and state policy, and taking into account the current nonlinear increased velocity of climate change, we concluded that discussing the uncertainties of large-scale models will have lower impact than to develop-validate mitigation strategies to be operative at local level, and compatibles with sustainable development, conservation biodiversity, and respect for cultural diversity.
