The ongoing COVID-19 pandemic around the world and in Russia remains a major event of 2020. All over the world, research is being conducted to comprehensively study the patterns and manifestations of the epidemic  process. The main quantitative characteristics of SARS-CoV-2 transmission dynamics among the population, based on the data of official monitoring over the current situation, play an important role in the development of  the epidemiological surveillance system.The aim of this study is to explore the peculiarities of age-gender distribution of COVID-19 patients in Moscow.Material and methods. The data related to the epidemiological characteristics of age-gender structure of COVID-19 patients in Moscow between March 19, 2020 and April 15, 2020, at different stages of the  epidemic were retrospectively analyzed.Results and discussion. The mean age of COVID-19 patients in Moscow was 46,41±20,58 years. The gender ratio (male/female) among the patients was 52.7/47.3 %, wherein the indicators varied depending upon the  age. Male/female ratio in the age group “under 39” stood at 53.7/46.3 %, and “over 40 years of age” – at  39.3/60.7 %. The predominant age range among male cases was 19 to 39 years old – 35.4 %, while among female patients – 40–59 years (36.5 %). The age distribution of patients in Moscow is indicative of the fact that COVID-19 is a disease that primarily affects older age groups. The age structure of all COVID-19 cases during the observation period is characterized by predominance of adult patients over 19 years of age – 92,7 % (92,6–92,8 %), the share of patients aged 40–59 years is 35,7% (35,5–35,9 %). The differences in the age distribution in males and females are as follows: in the male cohort, the age groups 19–39 years old and 40–59 years old prevail – 35.4 % (35.1–35.7 %) and 34.9 % (34.6–35.2 %), respectively. The age group 40–59 years old – 36.5 % (36.3–36.8%) dominates in the female cohort.

The paper presents the literature data analysis and statistical reports on the population morbidity of larval helminthiases in Russian Federation over the past 20 years. Epidemiological aspects of larval helminthiases in areas with different climatic, geographic and socio-economic conditions were determined.

Here we provide the assessment of COVID-19 epidemic in Italy, which scale has led to serious challenges both for society and national health care system. Despite timely information regarding the pandemic spread of the novel coronavirus infection, the country’s health care was not prepared to dramatically increased rate of patients with viral pneumonia at the first stage of the epidemic, infection control measures were not fully implemented that also led to spread of infection among health care workers. Socially vulnerable population groups did not seek timely medical care due to the lack of hospital facilities as well as well-trained medical personnel. At the second stage of developing epidemic, were also delayed and executed at varying timepoints in neighbor regions, with sustained insufficient management after implementing them that was reflected as ongoing rise of epidemic curve over long time. Delayed execution of anti-epidemic restrictive measures aimed at fighting against ongoing epidemic resulted in substantially increased morbidity and mortality among vulnerable population groups and retarded rate of decreasing COVID-19 epidemic curve. Analyzing response measures taken in Italy against COVID-19 epidemic should be appreciated by other countries while dealing with the current pandemic and preparing to react to novel biological threats in the future.
