The research aims to determine the intensity and direction of the impact of the global health and economic crisis from 2020 on the export competitiveness of the agri-food sector of the Republic of Serbia. Empirical study shows that there was an increase in the importance of exports of agri-food products in the crisis year 2020 according to all analysed indicators (net exports index, index of contribution to trade balance, relative coverage of imports by exports, unit values of exports). This confirms the hypothesis that this sector has exceptional resilience to crisis events. Moreover, net exports of these products increased significantly in 2020 compared to 2019 as a pre-crisis year. Therefore, the agri-food sector of the Republic of Serbia plays an important role in periods of such a crisis caused by non-economic factors, because it can compensate for the decline in exports and gross value added of other sectors.

Due to the growing concern for the environment and the impact of new technologies on it, companies are asking how to make a profit while respecting the problems of the environment. In this sense, they develop eco-innovations that do not reduce economic performance, but ultimately affect the strengthening of sustainable intellectual capital, sustainable competitiveness of enterprises and greater business efficiency. The goal of this paper is to point out the importance of the development of sustainable intellectual capital in modern business conditions and the role of eco-innovation within this intangible asset of the company.

Q fever is a globally widespread zoonosis, which has a large number of animal reservoirs. In humans, Q fever is asymptomatic in 60% of cases but may appear in the form of acute or chronic disease. The disease is mostly asymptomatic in animals but may be a cause of abortions or stillbirths. The aim of this study was to present and analyze the epidemiological characteristics of Q fever in Srem district, in the Autonomous Province of Vojvodina, Republic of Serbia. We conducted a descriptive study using data from the registries of infectious diseases of the Institutes of Public Health of Vojvodina and Institute of Public Health Sremska Mitrovica in the period 2011-2020. A total of 76 human cases of Q fever were registered in Srem district over ten-year period. The majority of patients (89.47%; N = 68) were registered in municipalities of Sremska Mitrovica and Šid. One third of patients were hospitalized (32.89%; N = 25). Males were 3.2 times more affected than females (M : F = 3.22 : 1). Working age population (20–59 years) were most affected (82.89%; N = 63) with a significantly higher incidence compared to the age category 0-19 years (p < 0.05). The majority of cases were registered in February (60.53%; N = 46). Probable routes of transmission of Coxiella burnetii were: direct contact with animals and the airborne route of transmission (50.00% vs. 47.37%). The highest seroprevalence of Q fever recorded in goats (55.54%) and sheep (11.88%) in the municipality of Šid, which is connected to outbreak in Kukujevci 2017. The high seroprevalence in goats, recorded in Inđija (22.87%) was not accompanied by Q fever in humans. Q fever still represents a significant problem of both veterinary and human medicine and therefore continuous disease monitoring and more efficient cooperation of the veterinary and human health care sectors is necessary.
