    Author's details edited by Fr archpriest Evgeny I. Legach, Konstantin S. Sharov
    Abstract This book is useful for administrators of different levels involved in counteracting COVID-19, surveillance professionals, clinicians, researchers specializing in epidemiology, microbiology, and infectious diseases, and politicians / legislators engaged in public health sector. We use an innovative approach of combining both epidemiological and sociological analyses, as the very problem is mainly an issue of correct governance. A team of authors from Europe, Russia and China summarizes their experience and knowledge useful for containing SARS-CoV-2 and overcoming social and managerial consequences of the pandemic. The editors are sure that sharing our different experience would help to elaborate necessary strategies, protocols, and principles that may be effectively applied in the future to avoid dramatic consequences of not only COVID-19 but also any possible epidemiological hazards for people and medicine.

    Abstract Background: The purpose of the work is to analyze population adaptation to SARS-CoV-2 in Europe in March-May 2020, predict herd immunity formation in the nearest several months on the basis of our SIR modified epidemiological model of the virus spread and elaborate recommendations to governments regarding a second wave of COVID-19 pandemic.
    Methods: Outer (1,006,512 RT-PCR tests results for SARS-CoV-2) and proprietary (34,660 respiratory samples) epidemiological data was used. Fifteen European countries were studied. Dates of research: March 2 - May 22, 2020.
    Results: As of April 21, 2020, the mean population infection rate (PIR) for the European countries considered, was 9.66%. It decreased to 6.85% by May 22, 2020. The model predicted 5.68% PIR, giving accuracy of 79.40%. SARS-CoV-2 basic reproduction number is limited by an extremum that may be observed for closed communities. A concept of effective reproduction number is introduced as a function of r
    Conclusion: In case of a second wave of COVID-19 disease in Europe, it will coincide with seasonal common cold surge, spanning from mid-September 2020 to mid-February 2021, with a median in November-December 2020. Strict epidemiological surveillance must be observed in Europe at that time.

    Abstract Objectives: The aim was to investigate if there is synergy in HIV infection and COVID-19 in their influence on human immunity, if there is an exacerbation of HIV patients' immune status caused by SARS-CoV-2; and if HIV infection without antiretroviral therapy (ART) leads to a more serious COVID-19 course than HIV infection with ART.
    Design: Anonymised blood samples and clinical data were collected in 47 hospitals, clinics and medical centres in six Russian cities/regions in the period from 20 March to 15 June 2020. Three hundred and seventy-six HIV/COVID-19 patients were studied (171 without ART and 205 with ART). The control group consisted of 382 SARS-CoV-2-positive patients without HIV infection. Lymphocyte and cytokine amounts were measured by flow cytometry and ELISA. This work is a retrospective study.
    Results: COVID-19 led to rapid augmentation of the process of T-cell exhaustion initially caused by HIV, and this T cell degradation was most pronounced in patients without ART. A rise in IL-10 and TGFβ serum concentrations was observed. Diminishing CD4
    Conclusions: HIV infection without ART may be a very serious comorbidity of COVID-19, whereas immunity of HIV/COVID-19 patients with proper ART is not generally affected by SARS-CoV-2. HIV-1 and SARS-CoV-2 are likely to exhibit a synergic effect, and exhausted T lymphocyte dynamics may be its effective marker.

    Abstract We propose a Susceptible-Infected-Recovered (SIR) modified model for Coronavirus disease - 2019 (COVID-19) spread to estimate the efficacy of lockdown measures introduced during the pandemic. As input data, we used COVID-19 epidemiological information collected in fifteen European countries either in private surveys or using official statistics. Thirteen countries implemented lockdown measures, two countries (Sweden, Iceland) not. As output parameters, we studied herd immunity level and time of formation. Comparison of these parameters was used as an indicator of effectiveness / ineffectiveness of lockdown measures. In the absence of a medical vaccine, herd immunity may be regarded as a factor of population adaptation to severe acute respiratory syndrome-related coronavirus-2, the viral pathogen causing COVID-19 disease (SARS-CoV-2), and hence COVID-19 spreading stop. We demonstrated that there is no significant difference between lockdown and no-lockdown modes of COVID-19 containment, in terms of both herd immunity level and the time of achieving its maximum. The rationale for personal and business lockdowns may be found in the avoidance of healthcare system overburdening. However, lockdowns do not prevent any virus with droplet transmission (including SARS-CoV-2) from spreading. Therefore, in case of a future viral pathogen emergence, lockdown measures efficiency should not be overestimated, as it was done almost universally in the world during COVID-19 pandemic.

    Abstract Background: We are communicating the results of investigating statistics on SARS-CoV-2-related pneumonias in Russia: percentage, mortality, cases with other viral agents, cases accompanied by secondary bacterial pneumonias, age breakdown, clinical course and outcome.
    Methods: We studied two sampling sets (Set 1 and Set 2). Set 1 consisted of results of testing 3382 assays of out-patients and hospital patients (5-88 years old) with community-acquired and hospital-acquired pneumonia of yet undetermined aetiology. Set 2 contained results of 1204 assays of hospital patients (12-94 years old) with pneumonia and COVID-19 already diagnosed by molecular biological techniques in test laboratories. The results were collected in twelve Russian cities/provinces in time range 2 March - 5 May 2020. Assays were analysed for 10 bacterial, 15 viral, 2 fungal and 2 parasitic aetiological agents.
    Results: In Set 1, 4.35% of total pneumonia cases were related to SARS-CoV-2, with substantially larger proportion (18.75%) of deaths of pneumonia with COVID-19 diagnosed. However, studying Set 2, we revealed that 52.82% patients in it were also positive for different typical and atypical aetiological agents usually causing pneumonia. 433 COVID-19 patients (35.96%) were tested positive for various bacterial aetiological agents, with
    Conclusions: SARS-CoV-2, a low-pathogenic virus itself, becomes exceptionally dangerous if secondary bacterial pneumonia attacks a COVID-19 patient as a complication. An essential part of the severest complications and mortality associated with COVID-19 in Russia in March-May 2020, may be attributed to secondary bacterial pneumonia and to a much less extent viral co-infections. The problem of hospital-acquired bacterial infection is exceptionally urgent in treating SARS-CoV-2 patients. The risk of secondary bacterial pneumonia and its further complications, should be given very serious attention in combating SARS-CoV-2.

    Abstract Background: Since the time of global SARS-CoV-2 spread across the earth in February 2020, most of countries faced the problem of massive stress of their healthcare systems. In many cases, the structural stress was a result of incorrect allocation of medical care resources. In turn, this misallocation resulted from fear and apprehensions that superseded thorough calculations. A key role in exacerbating the healthcare sector overburdening was played by misleading information on the virus and disease caused by it. In the current paper, we study the situation in Russian healthcare system and advance recommendations how to avoid further crises.
    Materials and methods: (a) Surveying the medical personnel (231 doctors, 317 nurses and 355 ambulance medical workers of lower levels) in five hospitals and six ambulance centres in Moscow. (b) Content analysis of 3164 accounts in Russian segment of social networks (VKontakte, Facebook, Instagram, Twitter, Odnoklassniki); official and unofficial media (TV, informational webpages).
    Results: We revealed positive-feedback loop that threatened the sustainability of Russian care sector. The main knot was occupied by incorrect/exaggerated media coverage of COVID-19. General public scared by misinformation in media and social networks, started to panic. This negative social background undermined the productivity of a significant part of medical workers who were afraid of COVID-19 patients.
    Conclusions: The most serious problems of Russian healthcare sector related to COVID-19 pandemic, were informational problems. The exaggerated information on COVID-19 had big negative influence upon Russian society and healthcare system, despite SARS-CoV-2 relatively low epidemiological hazard.
