Objectives: The aim of the current study was to describe COVID-19’s epidemiological characteristics in Oman during the initial stages of the outbreak and compare findings with other countries’ reports. Methods: Data were drawn from a descriptive, records-based review of reported cases of COVID-19 collected through the national COVID-19 Surveillance System from February to April 2020. Results: A total of 2,443 confirmed cases were reported during the study period. The overall first-time testing rate for this period was 851.7 per 100,000, the positivity rate was 53.1 (confidence intervals [CI]: 51.0–55.2) and the death rate was 0.32 (CI: 0.20–0.54) per 100,000 population, respectively. The overall national positive ratio was 5.7% and ranged from 2.2–7.1% across various governorates. Muscat Governorate had the highest positive ratio (12.5%). People in the 51–60 year old age group (RR = 1.97), males (RR = 1.24), non-Omanis (RR = 2.33) and those living in Muscat (RR = 2.14) emerged as categories with significant demographic risk for COVID-19 cases when compared to the national average. The mean age was 35.6 ± 13.4. Asymptomatic cases accounted for nearly 16%. Conclusion: The overall rate of COVID-19 cases and deaths were low in Oman compared to the rest of the world during the study period. Keywords: Coronavirus; COVID-19; SARS-CoV2; Epidemiology; Pandemic; Oman.

Background: SARS-CoV-2 virus is the causative agent of COVID-19 disease. It is essential to understand the epidemiological characteristics of the first few cases in each country. This study aimed to describe the geographical distribution, and temporal appearance of the first few hundred cases in Colombia. Methods: This observational study was conducted to review the literature and key documentary information from public health institutions, websites and news reports were examined. Results: The first few 100 cases for COVID-19 were confirmed in Colombia. According to sex, men with 54% predominate, the most affected age group was 20 to 29 yr old (26%), 9% of the cases required hospitalization and no deaths were reported. Most of the confirmed subjects were from the departments of Cundinamarca. To date, most cases are imported (63%), especially from Spain. Conclusion: The COVID-19 pandemic puts in evidence the lack of understanding, prevention and contention power of the different countries around the world is not as good as it could be. Politics must not affect the different proposed measures.

Objective The aim of this study was to investigate the prevalence of caries in South Vietnamese children with a known oral cleft. Setting The children were screened at local dental hospitals in five different cities in southern Vietnam. Participants One hundred fifty-four children aged 4 to 6, 11 to 13, and 14 to 16 years old with a cleft lip, cleft palate, or both were included in the study. Outcome Measurements For every age group, clefts were divided in four types. The dmft/DMFT was specified according to criteria of the World Health Organization (1997). Results The mean number of teeth affected by caries was 9.95 for 4- to 6-year-old children, 2.97 for 11- to 13-year-old children, and 4.93 for 14- to 16-year-old children, respectively. Four- to 6-year-old children with a unilateral or bilateral cleft lip and palate had significantly more caries and a higher dmft (decayed, missing, and filled teeth index) than children of the same age with only a cleft lip or a cleft lip and alveolus. Conclusions Vietnamese children with an oral cleft have high numbers of teeth affected by dental caries, and special attention will be necessary for their oral health.

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.

Background: The coronavirus disease 2019 (COVID-19) pandemic has rapidly spread to most countries around the world. Disproportionate spread of COVID-19 among the Indian community in Kuwait prompted heightened surveillance in this community. Aims: To study the epidemiological characteristics of COVID-19 patients and their contacts among the Indian community in Kuwait. Methods: Data collection was done as a part of contact tracing efforts undertaken by the Kuwaiti Ministry of Health. Results: We analysed contact-tracing data for the initial 1348 laboratory-confirmed Indian patients and 6357 contacts (5681 close and 676 casual). The mean (standard deviation) age of the patients was 39.43 (10.5) years and 76.5% of the cases were asymptomatic or had only mild symptoms. Asymptomatic patients were significantly older [40.05 (10.42) years] than patients with severe symptoms [37.54 (10.54) years] (P = 0.024). About 70% of the patients were living in shared accommodation. Most of the close contacts were living in the same household, as compared with casual contacts, who were primarily workplace contacts (P < 0.001). Among the different occupations, healthcare workers had the highest proportion of cases (18.4%). Among the 216 pairs of cases with a clear relationship between the index and secondary cases, the mean serial interval was estimated to be 3.89 (3.69) days, with a median of 3 and interquartile range of 1–5 days. Conclusion: An early increase in the number of COVID-19 cases among the Indian community could be primarily attributed to crowded living conditions and the high proportion of healthcare workers in this community.

Today the world's attention is focused on China, on the epidemic caused by coronavirus infection. As of the end of February, more than 77 thousand people affected with the disease had been registered, fatal outcome had been observed in more than 2500 cases. The Chinese authorities announced the beginning of a new epidemic at the very end of 2019. Moreover, if fatal outcomes were observed a month after the onset of mass incidence only within the country, then, in February, they went beyond its borders and were registered in Japan, Taiwan, South Korea, Iran, the Philippines, France and Italy. It is noteworthy that China became a source of the spread of the epidemic process not for the first time. So, in 2002 it was in this country, in Guangdong, that an outbreak of SARS was recorded, and in 1997, avian influenza spread from Hong Kong around the world. To tell the truth, the death rate from these diseases did not exceed thousands of people in both cases, and in the case of bird flu (or avian influenza), development of the disease was observed only in people eating chicken meat. It should be noted that in the entire history of the development of mankind, more people died as a result of epidemics and pandemics, than in all wars combined. Let us recall the worst epidemics in the history of mankind, the victims of which were millions of people.

Objective: chronic kidney disease (CKD) is an increasing common problem in the world due to the exponential growth of diabetes mellitus, hypertension and other risk factors. The aim of this study is to investigate urinary abnormalities and risk factors for kidney disease in the general population. Methods: this study was performed from data collected during the annual World Kidney Day (WKD) campaigns, in Fortaleza, Ceará, Brazil, between 2009 and 2012. The population sought assistance spontaneously in stands placed in high people-traffic areas. Results: among 2,637 individuals interviewed, the mean age was 50.7±15.7 years and 53% were male. The main risk factors found were sedentarism (60.7%), obesity (22.7%) and smoking (19.8%). Blood pressure (BP) > 140x90 mmHg was found in 877 (33%). Increased BP was found for the first time in 527 cases (19.9%). Cardiovascular diseases were reported in 228 (8.6%). Diabetes was related by 343 (13%). Capillary blood glucose > 200 mg/dL was found in 127 (4.8%) and it was > 200 mg/dL for the first time in 30 (1.13%). Urinalysis was performed in 1,151 people and found proteinuria in 269 (23.3%). Proteinuria was most frequent in hypertension people (77.3% vs. 55.8%, p=0.0001), diabetes mellitus (22.7% vs. 15.2%, p=0.005) and elderly (42.1% vs. 30.7%, p=0.0007). Conclusion: risk factors for CKD are frequent in the general population. Many individuals had hypertension and diabetes and did not know this. It is important to regularly perform actions like WKD in order to early detect potential candidates for CKD.

During recent decades the vital statistics of the more developed countries of the world have exhibited two outstanding features: the first is a decline in the death‐rate, and the second a similar decline in the birth‐rate, the latter setting in some time after the former. It is generally realised that, for an adequate study of the changes involved, it is necessary, not merely to consider the crude death‐ and birth‐rates—that is, the number of deaths and births respectively per 1000 inhabitants—but also to take into account the age distribution of the population. In the case of death‐rates, for instance, it is important to know the specific death‐rates for each age-group—that is to say, for example, the annual number of deaths of persons aged twenty, per 1000 individuals of that particular age. In the same way the crude birth‐rate can only be properly interpreted when analysed in reference to the age of the mothers.

SummaryHospital Activity Analysis data and record linkage were used to investigate repetition of self-poisoning, and deaths, among 2,492 people, aged 12 to 20 years, who took overdoses between 1974 and 1978. Repetition occurred most frequently during the first few months after an initial admission; 9.5% of patients repeated within the study period (mean follow-up of 2.8 years). Ten of the 2,492 subjects died during the study period, and the average annual death rate in the cohort was approximately four times higher than the national average annual death rate in this age-group as a whole. Six of the deaths were probably suicides. Repetition and suicide rates were highest among males aged 16 to 20 years.

In 1921 was published the book of the famous Austrian-British philosopher and funder of the analytic philosophy Ludwig Johann Wittgenstein, in which he wrote, that the big part of our philosophical problems, which were subject of the thinking of the thousands philosophers, are created not by the difficulty of reality but by the complication of the language. When a philosopher analyzes a language he uses, he will find that the biggest part of the philosophical problems is illusory. Following Wittgenstein's advices, in this article we probe to analyze what means the concept "polytheism" and to answer the questions: did the phenomenon, what is with this word described, anytime exist, or it is only a phantasies' fabrication, and all attempts to think about it are wandering in the dark labyrinths without exit. The first problem we have in our way is absolutely darkness in this question. We could not find any research, in which the concept of polytheism is analyzed in this way we changed. So we must get through the forest of an unknown ourselves without opportunity to have support from the experience of the predecessors. We hope our mistakes might be useful for the following researches. The Greek word "doxa polytheos" was first time used by Philo of Alexandria and after them many Judaic and Christian authors repeated this word opposing own religion to the paganism. Jan Bodin 1n 16th Century used this word in the modern mean as a France word "polythéisme". The Greek word "doxa polytheos" and the France one "polythéisme", though they are constructed of the same Greek word "Θεός", based on the different concepts, because in 16 centuries the word "Θεός" changed its means. In Greek-speaking society this word was used to detonate any being who overstate the material world. When Thales of Millet wrote, that "the world is full of gods", he did not mean that there is an Absolut in every small part of the world. When he used the word "Θεός" in this mean, Thales thought about different objects, as we called "God" now. The mean of the term "polytheism" is unclear and is the cause of many researches problems in the religious studies. The Greek word "Θεός" detonated every sacral being, which was the object of the worship, but not the Absolut. When this word went in the term "polytheism", its mean was changed, and it was used for the calling Absolut in the Christian meaning. This transformation of the meaning created the wrong conception that in the world there were or are religions, the members of them believes in the existence of some or many Absolutes. The problem of using concept "polytheism" is not a real academic problem but an illusions problem, what is caused by the wrong and incorrect using of the term. The Greek word "Θεός", of them are created the terms "monotheism" and "polytheism", is used in both terms in different meanings. In the term "monotheism" the word "Θεός" means God-Absolut, and in the term "polytheism" – any beings, what are the objects of the religious worship. The monotheism and polytheism are not two different phase of the entvelopment of the religious consciousness. These ideas are created by the wrongness of Hegel's philosophy and must be uprooted from the lexicon of the religious studies.

The second wave of Covid -19 in India has made us witness as to how negligence from the part of everyone of us, be it people, Government or policy makers of healthcare system might bring the unwanted disaster in the form of Covid Tsunami. This has made us to see never ending queues of patients , relatives standing for hours for the want of hospital beds, oxygen, essential medicines and lastly but unfortunate for their turn for the cremations of loved ones . But now we can see the number of active cases are declining across the country. Amidst this positive observation in regard of second wave ,there is speculation erupting about the Covid third wave. We can appreciate a similarity in the way that the noble corona virus behave with the Spanish flu that had shaken the world in 1918. It had resulted in three waves with second wave was most deadly and long lasting than the other two waves. During the first wave where the infection was mostly of mild severity we had seen the disease affecting the elderly and immune-compromised patients more. In contrast to this, second wave resulting from mutant strains affected the younger population more and it was of larger severity with high mortality rate. Scientists and experts are now anticipating the third wave , taking the lesson from the Spanish flu and we must be better prepare for it. In order to prepare ourselves from a expected third wave of Covid-19, we shouldn’t repeat mistakes that we made during previos waves. We should refrain ourselves from dismantling our enhanced healthcare facilities, there should not be any sorts of shortage of oxygen , hospital beds, and drug that we have already witnessed. We must have an aggressive containment measure comprising of a really strong and pro-active surveillance system. This can be achieved by increasing the capacity of the existing surveillance system by identifying active cases early. We must ensure that we should follow “social vaccine” of proper masking, avoid indoor gatherings, and proper sanitization. Our vaccination programme needs a boost. We should vaccinate a large section of people before any third wave hits us. The more we vaccinate, the better prepared we are. As medical professionals, it must be ensured that proper scientific protocol must be implemented while handling Covid-19 cases. And last but not the least efforts must be made to fill up vacancies seen in our public health system, especially for frontline healthcare workers. As it is anticipated that the young children are more vulnerable to the forthcoming third wave, efforts are to be sought in order to start vaccination of the younger children in our country. Trials for which has already been started in India and across the world. Till the time vaccine is made available, the resources are to be mobilized to build up healthcare facilities catering the vulnerable age group in this third wave such as building up of more paediatric wards, paediatric ICU’s , training of healthcare personals in handling the emergencies for expected third wave .In addition to these efforts , more and more paediatric covid care centers must be set up at various parts of the country. Equally important is making arrangements for rehabilitation centers for the orphans. Countries like US, Singapore and UAE have already started vaccinating the children in age group between 12 to 15 years with Pfizer-BioNTech Covid vaccine. It’s a high time that the government in India must consider for allowing “expedited approval pathway” to the companies like Pfizer for their Covid-19 vaccine for children. All these combined efforts from everyone may ensure that the country and world may remain well equipped against these subsequent waves of this deadly virus and pave the path of the triumph in the near future.
