Gas emission by humans will change climate, warming by 1.4-5.8°C as predicted at the end of the current century. Climate oscillations between warm and cold phases (El Niño) add complexity in the field. The effects on health could be thermal stress, extreme weather events, and subsequently emerging infectious diseases. Consequences on food yields, social, demographic and economic imbalances, cou...

Infectious diseases, and especially viral diseases, can be prevented or controlled by several means. For many years, only hygienic measures based on animal culling were the methods of choice to control highly contagious diseases, like foot-and-mouth-disease (FMD) virus which can spread very quickly and very efficiently in a naïve population (Grubman & Baxt, 2004). Due to the development of new ...

This paper proposes a test for the existence and degree of contagious presenteeism and negative externalities in sickness insurance schemes. First, we theoretically decompose moral hazard into shirking and contagious presenteeism behavior and derive testable conditions. Then, we implement the test exploiting German sick pay reforms and administrative industry-level data on certified sick leave ...

respiratory disorders are major concern for dairy cattle industry. viruses and bacteria in combinationwith stress play a key role in triggering acute respiratory infections. the most important viral agents arebovine viral diarrhoea virus (bvdv), bovine herpes virus type 1 (bhv-1), bovine respiratory syncytial virus(brsv), parainfluenza virus type 3 (piv-3) and bovine adenovirus (bav). this cros...

Background: Nowadays, the COVID-19 pandemic has become a global problem that new methods must be used to prevent it. The virus is highly contagious and is mainly transmitted through the air. Ozone is a powerful oxidant that can be used to inactivate a wide range of viruses that may be resistant to other disinfectants. The purpose of this study was to review the use and effect of ozone in inacti...
