The epidemics of COVID-19 started in December 2019 in Wuhan, China, and the World Health Organization (WHO) officially declared a pandemic in March 2020. COVID-19 can also affect the eyes. Ophthalmic manifestations of the virus are not so frequent; the prevalence is about 3% up to now. Recognizing the possibility of ophthalmic transmission and manifestation of the virus is of significant importance for ophthalmologists and health workers. According to published studies, the most common ophthalmic manifestation is follicular conjunctivitis with all the symptoms and signs of viral conjunctivitis. It is usually bilateral, and patients present adenoviral-like symptoms, discomfort, foreign body sensation, redness, or they have no subjective symptoms. The symptoms are more pronounced in patients with a more severe clinical picture of the disease. One of the described non-specific manifestations of COVID-19 as an initial manifestation is keratoconjunctivitis. The effects of the virus on the retina and blood vessels have not been fully investigated, yet. It has been proven that COVID-19 can be isolated from tears and from ocular surface by PCR conjunctival swab. The most common mode of transmission is through direct contact and through aerosols. Through the nasolacrimal system, the eyes can be the entrance for respiratory infection and hematogenous spread of the virus can occur through the lacrimal gland. Early recognition of the ophthalmic symptoms by ophthalmologists as well as the other health workers during this pandemic is necessary because sometimes they can be the only manifestation of COVID-19, and on the other hand, it will lead to greater protection and prevention of the virus spreading. Prevention measures should be focused on the application of administrative protocols, personal protection and environmental control.

The first human cases of coronavirus disease (COVID-19), a disease caused by the new coronavirus, was reported on December 31, 2019 in China for the first time. Тhe virus was named temporarily as 2019 new coronavirus (2019 novel coronavirus-2019 -nCoV), or finally as SARS-CoV-2. The aim of this paper is to give an overview of the laboratory detection of SARS-CoV-2 virus with reverse transcriptase - polymerase chain reaction (RT-PCR) in real time, as well as detection of viral mutations in the Laboratory for virology at the Institute of Public Health. The samples used in the study were taken from all geographical regions in North Macedonia, including the 10 regional Centers for Public Health throughout the country, from hospital patients, from COVID19 hospitals across the country and from the COVID19 checkpoint at the Institute of Public Health. All samples were tested using RT-PCR in real time. Additional assays were applied for identification of the circulating variants. The continuous surveillance of the variants of concern (VOC), as well as the newly emerged variants can allow the public health officials to modify their approach to disease control and management and intervene more effectively as well as in a timely manner in order to prevent major morbidity and mortality from COVID-19.

COVID-19 is an infectious disease that can manifest quite differently. In this study we examined the relationship between the value of serum CRP(C-reactive protein) andneutrophil-lymphocyte ratio (NLR) as predictor factors for the development of a severe clinical manifestation in COVID19 patients. Materials and methods: We followed 95 COVID-19 positive patients who were hospitalized at the University Clinic for Eye Diseases - COVID Center. We analyzed the initial laboratory parameters of white blood cells and CRP on admission of the patients and the results of laboratory analyses performed before they left the Clinic, or the last parameters before the lethal outcome in those patients who died. Several models of logistic regression were tested to analyze the predictive value of these markers of inflammation for lethal outcome in patients hospitalized for COVID-19. Results: Bivariate analysis demonstrated that the length of hospital stay was significantly shorter in patients with lethal outcome (p=0.001). The NLR was significantly higher in patients with lethal outcome at both times (p=0.005; and p=0.017). Leukocyte’s count (p=0.046, and p<0.001) and CRP (p=0.013,and p=0.005) were also significantly higher in patients with lethal outcome at both times. The increase on the NLR scale both at hospitalization and at discharge (or the last analysis before death) leads to increase in the odds of lethal outcome (T1:40.4% increased odds; T2:36% increased odds). Conclusion: CRP and NLR are laboratory parameters that can predict the severity of the clinical manifestation in patients with COVID-19.

The current pandemic of corona virus disease 2019 (COVID-19) is an infectious disease caused by a newly discovered severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2). Global COVID-19 burden is characterized by a high variability in death rate across countries. Several possible explanations have been proposed, but it is not clear whether this variability is due to a single predominant factor or instead to multiple causes. The aim of this paper was to present and analyze the epidemiological situation and burden of the COVID-19 pandemic in Kosovo compared to other countries in Europe and the world. Material and methods: Public health approach and desk review were applied to present and analyze the trends over time of selected epidemiological indicators for COVID-19 based on multiple sources of data as well as WHO epidata and literature review. The assessment of the epidemiological situation in EU/EEA member states was done using the surveillance data routinely collected by ECDC. Official medical records from the National Institute of Public Health, other relevant health institutions; State Statistical Office and Ministry of Health in Kosovo were used. Results: According to ECDC as of 11 February 2021, 106,472,660 cases of COVID-19 (in accordance with the applied case definitions and testing strategies in the affected countries) have been reported, including 2,323,103 deaths. COVID-19 cases have been reported from: Africa: 3,673,181 cases, Asia: 20,438,608 cases, Europe: 34,681,426 cases, America: 47,620,931 cases; Oceania: 57,809 cases, Others: 705 cases. Deaths have been reported from: Africa 95,128 deaths, Asia 343,886, America 1,107,066, Europe 775,883, Oceania 1,210 and Other 6 deaths. In Kosovo from 13 March 2020 until 15th February 2021 there have been 64,298 cases of COVID- 19 with 1534 deaths. Absolute values of the indicators remain high in all countries in Europe, including those with stable or decreasing trends in these indicators, suggesting that transmission is still wide spread. The epidemic trajectory over the next months will be determined by the balance of four factors, with many different outcomes possible: the continued scale-up of vaccination, declining seasonality, the spread of new variants and increased behaviors that favor COVID-19 transmission. Conclusion: Findings from this paper can help to develop evidence-based policy interventions in Kosovo for risk assessment of COVID-19 and protection of general population and especially vulnerable groups with higher risk from COVID 19.

The aim of the paper was to evaluate clinical characteristics of COVID-19 in children and the success of the treatment. Material and methods: The study included 218 pediatric patients suspected for COVID-19 hospitalized at the Institute for Pulmonary Diseases in Children-Skopje, during the period from 16th of March to 19th of June 2020. All patients were tested for presence of SARS-CoV-2 virus in nasopharyngeal swab with real-time reverse transcription polymerase chain reaction (RT-PCR) in the Institute of Public Health of Republic of North Macedonia. Clinical symptoms, X-ray and laboratory findings were included in the study. Results: From 218 hospitalized patients, only 9 (4.13%) were positive for COVID-19 and 59% of them were males. Infants, with moderate pulmonary disease were 44.4% of the patients. Fever and gastrointestinal symptoms were present in 66.6% and 22.2% of the children, respectively. Macrolides were therapy of choice in 88% of the treated patients, 77% received intravenous therapy, 33% were on inhaled bronchodilator. Conclusions: A small number of children had COVID-19. All infected children were with mild to moderate pulmonary symptoms and reacted satisfactory to the treatment. However, the importance of transmitting the virus and influence over children’s health remains uncertain.

The COVID-19 pandemic is an unprecedented global crisis in public health. Professionals in dental institutions, dental associations and regulatory bodies face various challenges in providing dental care and prevention of oral health of the population, as well as protection of patients and practitioners from the health threat of SARS-CoV-2 virus. The aim of this paper is to present the current findings and views regarding the information on the epidemiological and clinical characteristics of the SARS-CoV-2 virus and the need to implement protocols to protect patients and dental practitioners from the health threat posed by the virus, in compliance with medically relevant regulations.Material and methods: References from WHO, FDI and published papers in international scientific journals in this relatively short period were consulted and they presented: updated epidemiological and seroepidemiological information, review of response measures implemented in EU countries / EEA, UK and countries around the world and response options to minimize the risk of recurrence of COVID-19. Results: Viral pneumonia that appeared on February 11, 2020, was named "Coronavirus (COVID 19)" by the WHO, while the International Committee on Taxonomy of Viruses (ICTV) proposed the name "SARS-CoV-2" for phylogenetic and taxonomic analysis of this corona virus. Dentists/doctors of dental medicine should be familiar with transmission of SARS-CoV-2, how to identify patients with SARS-CoV-2 infection and what measures should be taken for protection during the intervention in order to prevent its transmission. There are recommendations for infection control measures that should be followed by the dentists/doctors of dental medicine. The fact that aerosols and drops have been considered for major SARS-CoV-2 propagation routes has been emphasized. If these measures are not undertaken, then the dental office can potentially expose patients to cross-infection. Conclusion: The epidemiological situation around the world is changing dynamically, but patients should not be left without urgent medical help. Oral health team members are required to update their knowledge and skills regarding the prevention, diagnosis and management of communicable diseases that can be transmitted in a clinical setting and to stick to the standard precautions to protect patients from infections as well as protect themselves.
