This paper treats long-term changes in area of the ?lichen desert?, i.e., the region characterized (especially in the winter period) by average daily SO2 concentration exceeding 150?g/m3 of air, the maximum allowable concentration (MAC) for populated regions. Comparison of results obtained in 1980/81 and 1991 indicates that the ?lichen desert? expanded (from 12 to about 13 km2) as a consequence of deterioration of the air quality in the Belgrade area. Comparing the results obtained in 1991 with investigations carried out in 2007, we found that ?lichen desert? shrank substantially in the Belgrade area to a current size of about 11 km2. The new boundaries of the ?lichen desert? are presented, together with the main reasons for its shrinkage in the Belgrade area during the last 16 years and predictions of further alterations in the future.

There is a current pandemic of a new type of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The number of confirmed infected cases has been rapidly increasing. This paper analyzes the characteristics of SARS-CoV-2 in comparison with Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), Middle East Respiratory Syndrome Coronavirus (MERS-CoV) and influenza. COVID-19 is similar to the diseases caused by SARS-CoV and MERS-CoV virologically and etiologically, but closer to influenza in epidemiology and virulence. The comparison provides a new perspective for the future of the disease control, and offers some ideas in the prevention and control management strategy. The large number of infectious people from the origin, and the highly infectious and occult nature have been two major problems, making the virus difficult to eradicate. We thus need to contemplate the possibility of long-term co-existence with COVID-19.

Background: There is a current worldwide outbreak of a new type of coronavirus COVID-19. The number of confirmed infected cases is rapidly increasing. Method: This paper analyzes the characteristics of COVID-19 in comparison with Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV), Middle East Respiratory Syndrome Coronavirus (MERS-CoV) and influenza. Diagnostic data for foreign citizens evacuated from Wuhan were collected and compiled. Current prevention and control strategies have been analyzed. Results: COVID-19 is similar to SARS-CoV and MERS-CoV virologically and etiologically, but similar to influenza in epidemiology and virulence. The prevalence rate in Wuhan was inferred to be close to 1%. The comparison provides a new perspective for the future of the disease, and offers some advice in the prevention and control management strategy. Conclusion: The large number of patients and the strong occult nature are two big problems, making the virus difficult to eradicate. We need to contemplate the possibility of long-term co-existence with COVID-19.
