The outbreak of the COVID-19 global pandemic has strongly affected different issues of everyday life. The pandemic has changed consumer attitudes and behavior. Consequently, during COVID-19, businesses had to decide how to organize the advertising campaigns and what content should be addressed to consumers. Considering the limited number of articles concerning these issues, it seems important to evaluate the impact of the global health crisis on advertising messages in different countries. The main objective of this paper is to assess TV commercial campaigns implemented during the COVID-19 pandemic, including the specific epidemic situation in the selected countries. The research methodology was based on the observation, a qualitative method of collecting data obtained through monitoring the content of TV commercials aired during the afternoon, before or after the main news service. The research was conducted in May 2020 and in May 2021 in five selected European countries affected to varying degrees by the coronavirus pandemic. The research results allowed evaluation of the advertising messages in terms of their content and values exposed. The findings indicate that the number of COVID-related TV commercials is not correlated with the number of patients and deaths from COVID-19. The themes appearing the most often in the TV commercials in the studied period were the #StayAtHome idea, family and friends, the aspect of safety during the crisis, and brands' special offers. The tone of the advertisements was usually uplifting and hopeful, trying to cheer the stressed societies. From a theoretical perspective, the research results show the advertising strategy issues in specific conditions in different European countries. These findings concerning TV commercial strategy during a pandemic crisis could provide references for other countries, especially in Europe. The research results could be useful for marketing managers in developing strategies concerning the successful planning of TV commercials in crisis periods in European countries.

The COVID-19 vaccination campaigns were met with a varying level of vaccine hesitancy in Europe. We analyzed the potential relationships between COVID-19 vaccine coverage in different countries of the European Economic Area and rates of infection, hospitalizations, admissions to intensive care units (ICU), and deaths during the autumn 2021 SARS-CoV-2 wave (September−December). Significant negative correlations between infection rates and the percentage of fully vaccinated individuals were found during September, October, and November, but not December. The loss of this protective effect in December is likely due to the emergence of the omicron (B.1.1.529) variant, better adapted to evade vaccine-induced humoral immunity. For every considered month, the negative linear associations between the vaccine coverage and mean number of hospitalizations (r= −0.61 to −0.88), the mean number of ICU admissions (r= −0.62 to −0.81), and death rate (r= −0.64 to −0.84) were observed. The results highlight that vaccines provided significant benefits during autumn 2021. The vaccination of unvaccinated individuals should remain the primary strategy to decrease the hospital overloads, severe consequences of COVID-19, and deaths. [ABSTRACT FROM AUTHOR]

The WHO has announced the novel coronavirus disease (COVID-19) outbreak to be a global pandemic. The distribution of community outbreaks shows seasonal patterns along certain latitude, temperature and humidity, that is, similar to the behaviour of seasonal viral respiratory tract infections. COVID-19 displays significant spread in northern mid-latitude countries with an average temperature of 5–11°C and low humidity. Vitamin D deficiency has also been described as pandemic, especially in Europe. Regardless of age, ethnicity and latitude, recent data showed that 40 % of Europeans are vitamin D deficient (25-hydroxyvitamin D (25(OH)D) levels <50 nmol/l), and 13 % are severely deficient (25(OH)D < 30 nmol/l). A quadratic relationship was found between the prevalences of vitamin D deficiency in most commonly affected countries by COVID-19 and the latitudes. Vitamin D deficiency is more common in the subtropical and mid-latitude countries than the tropical and high-latitude countries. The most commonly affected countries with severe vitamin D deficiency are from the subtropical (Saudi Arabia 46 %; Qatar 46 %; Iran 33·4 %; Chile 26·4 %) and mid-latitude (France 27·3 %; Portugal 21·2 %; Austria 19·3 %) regions. Severe vitamin D deficiency was found to be nearly 0 % in some high-latitude countries (e.g. Norway, Finland, Sweden, Denmark and Netherlands). Accordingly, we would like to call attention to the possible association between severe vitamin D deficiency and mortality pertaining to COVID-19. Given its rare side effects and relatively wide safety, prophylactic vitamin D supplementation and/or food fortification might reasonably serve as a very convenient adjuvant therapy for these two worldwide public health problems alike.

Background: The clinical presentation of European patients with mild-to-moderate COVID-19 infection is still unknown.Objective: To study the clinical presentation of COVID-19 in Europe.Methods: Patients with positive diagnosis of COVID-19 were recruited from 18 European hospitals. Epidemiological and clinical data were obtained through a standardized questionnaire. Bayesian analysis was used for analysing the relationship between outcomes.Results: A total of 1,420 patients completed the study (962 females, 30.7% of healthcare workers). The mean age of patients was 39.17 ± 12.09 years. The most common symptoms were headache (70.3%), loss of smell (70.2%), nasal obstruction (67.8%), cough (63.2%), asthenia (63.3%), myalgia (62.5%), rhinorrhea (60.1%), gustatory dysfunction (54.2%) and sore throat (52.9%). Fever was reported by 45.4%. The mean duration of COVID-19 symptoms of mild-to-moderate cured patients was 11.5 ± 5.7 days. The prevalence of symptoms significantly varied according to age and sex. Young patients more frequently had ear, nose and throat complaints, whereas elderly individuals often presented fever, fatigue and loss of appetite. Loss of smell, headache, nasal obstruction and fatigue were more prevalent in female patients. The loss of smell was a key symptom of mild-to-moderate COVID-19 patients and was not associated with nasal obstruction and rhinorrhea. Loss of smell persisted at least 7 days after the disease in 37.5% of cured patients.Conclusion: The clinical presentation of mild-to-moderate COVID-19 substantially varies according to the age and the sex characteristics of patients. Olfactory dysfunction seems to be an important underestimated symptom of mild-to-moderate COVID-19 that needs to be recognized as such by the WHO. [ABSTRACT FROM AUTHOR]
