On March 11, 2020, the World Health Organization declared the coronavirus outbreak a pandemic. Since December 2019, the world has experienced an outbreak of coronavirus disease 2019 (COVID-19). Epidemiology, risk factors, and clinical characteristics of patients with COVID-19 have been reported but the factors affecting the immune system against COVID-19 have not been well described. In this article, we provide a novel hypothesis to describe how an increase in cellular adenosine triphosphate (c-ATP) can potentially improve the efficiency of innate and adaptive immune systems to either prevent and fight off COVID-19.

Novel Coronavirus are very harmful virus. This viruses have positive single stranded RNA genome and enveloped which is called nucleocapsid. The family of this virus is Coronaviridae. This virus originated from species of avian and mammalian. This virus effect on upper respiratory tract in humans. Many species of these novel coronaviruses (HCoVs) are named as HCoV-HKU1, HCoV-NL63. Predominant species of this virus is Middle East respiratory syndrome (MERS-CoV) across the world.  In both adults and childrens HCoV-HKU1 sp. is causes for chronic pulmonary disease and HCoV-NL63 species causes for upper and lower respiratory tract disease. Most recent species of this virus is MERS-CoV. This species caused for acute pneumonia and occasional renal failure. The new strain of novel Coronavirus is SARS-CoV-2. This strain causes for the Coronavirus Disease 2019 (COVID-19). This disease named by the World Health Organization. Now world fighting against COVID-19 and according to the recent statistics report of world about the COVID-19 cases approx 22.6M confirmed cases and 792K death cases appeared and recovered 14.5M. COVID-19 disease starts to spread from December 2019 from china. Covid-19 disease is emerged in Wuhan seafood market at Wuhan of South China and then rapidly spread throughout the world. The corona virus outbreak has been declared a public health emergency of International concern by World Health Organization (WHO). In this article we summarize the current clinical characteristics of coronavirus and diagnosis, treatments and prevention of COVID-19 disease. In this review article, we analyze data from various Research Reports like WHO guidelines and other articles. It is very important to the readers that new data of COVID-19 updating nearly every hour of day regarding clinical characteristics, diagnosis, treatment strategies, and outcomes COVID-19 disease. The degree of COVID-19 disease varying throughout the world. COVID-19 affected patient shows various symptoms like fever, cough, sore throat, breathlessness, fatigue, and malaise among others. The COVID-19 disease is being treated through general treatment like symptomatic treatment, by using antiviral drugs, oxygen therapy and by the immune system. There is no vaccine or therapeutic strategies for deal with this disease yet. In this critical situation preventive measures must be require.  A very important issue in preventing viral infection is hand hygiene. There are other entities that people can boosting the immune system and help in infection prevention.

Abstract The World Health Organization set a target of a 15% relative reduction in the prevalence of insufficient physical activity (IPA) by 2025 among adolescents and adults globally. In Bangladesh, there are no national estimates of the prevalence of IPA among adolescents. The aim of this study was to estimate the prevalence of and risk factors associated with IPA among adolescent girls and boys. Data for 4865 adolescent girls and 4907 adolescent boys, collected as a part of a National Nutrition Surveillance in 2018–19, were analysed for this study. A modified version of the Global Physical Activity Questionnaire (GPAQ) was used to collect physical activity data. The World Health Organization recommended cut-off points were used to estimate the prevalence of IPA. Bivariate and multivariable logistic regression was performed to identify factors associated with IPA. Prevalences of IPA among adolescent girls and boys were 50.3% and 29.0%, respectively, and the prevalence was significantly higher among early adolescents (10–14 years) than late adolescents (15–19 years) among both boys and girls. The IPA prevalence was highest among adolescents living in non-slum urban areas (girls: 77.7%; boys: 64.1%). For both boys and girls, younger age, non-slum urban residence, higher paternal education and increased television viewing time were significantly associated with IPA. Additionally, residing in slums was significantly associated with IPA only among the boys. Higher maternal education was associated with IPA only among the girls. This study identified several modifiable risk factors associated with IPA among adolescent boys and girls in Bangladesh. These factors should be addressed through comprehensive public health interventions to promote physical activity among adolescent girls and boys.

On March 11, 2020, the World Health Organization (WHO) released a statement characterizing COVID-19 as a pandemic that has, as of October 2020, caused almost 36 million confirmed global cases and over 1 million deaths. One of the long-term complications suggested by researchers is fibrosis. It has been hypothesized that the combination of ongoing pulmonary injury caused by COVID-19 and the inability to promptly repair damage results in interstitial matrix widening and eventual compression and destruction of alveoli and capillaries. Here we focus on pathogenesis, risk factors, different infectious causes of fibrosis along with COVID-19, and potential treatment options that might reduce its effects. Key words: COVID-19, pulmonary fibrosis, mechanism, treatment

The coronavirus disease 2019 (COVID-19) epidemic originated in Wuhan, China and spread rapidly worldwide, leading the World Health Organization to declare an official global COVID- 19 pandemic in March 2020. The upper aero-digestive tract is known to be the highest viral load reside. The infection spreads via droplets or direct contact with contaminated surfaces via aeorsol. The otolaryngologists deal with diseases of the upper-aerodigestive tract and routinely are engaged in respiratory droplet and aerosol-generating procedures (AGP). In particular, because airborne transmission occurs during examination and AGP, otolaryngologists are considered to be at a high risk of contracting COVID-19 during this pandemic. Therefore otolaryngologists need to do precautions to protect staff and patients and minimize transmission of the disease. We also need to wear adequate personal protective equipment according to the examination and procedure. This article discusses the disease transmission and clinical characteristics of COVID-19 as well as precaution guidelines in outpatient clinics of otorhinolaryngology.

In December 2019, the Chinese government alerted the world to a dangerous virus that spread rapidly in communities. In fact, another acute respiratory syndrome occurred in Wuhan, China, and then spread rapidly to other parts of the world. The World Health Organization (WHO) refers to this virus as nCoV-2019, where n stands for “new” and CoV stands for “coronavirus”. In general, the virus (COVID-19) is similar to acute respiratory syndrome (MERS-CoV), but they are by no means identical

Coronavirus disease 2019 (COVID-19) is a global pandemic caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection, affecting millions of people worldwide due to its ease of transmission. Despite limited information on effective therapeutic options, vitamin D has been regularly reported to exert beneficial immunomodulatory effects affecting both innate and adaptive immune systems. As it is synthesized in the skin under ultraviolet radiation, population living in equatorial countries are presumed to have adequate vitamin D, however several studies have shown otherwise. This article is aimed to give an insight on the different mechanisms by which vitamin D affects our immune system in COVID-19, as well as discussing correlation of having sunlight all year round by being near the equator towards vitamin D adequacy.

Cardiovascular Diseases represent the main cause of death in the world, and are associated with risk factors that cause serious complications in cases of infections, such as those of the respiratory tract. In March 2020 the World Health Organization declared a pandemic for SARS-CoV-2, a new coronavirus causing severe pneumonia, which emerged in December 2019 in Wuhan, China. The objective is to investigate the occurrence of cardiovascular complications associated with SARS-CoV-2 infection. It is a systematic review, quantitative, in the databases, PubMed and Science direct, including primary studies with hospitalized patients confirmed for COVID-19 and who presented cardiovascular complications, the form used tools for evaluation of quality and evidence, following the PRISMA recommendations. Results: 12 studies were included. The occurrence of cardiovascular complications was: 27.35% of the sample of 3,316 patients. Types: Acute cardiac injury 17.09%; Thromboembolism 4.73%; Heart failure 3.43%; Arrhythmias 1.77%; stroke 0.33%. Mean age 61 years. Conclusions: This study showed that there are several cardiovascular complications associated with SARS-CoV-2, that the main one is acute cardiac injury, which causes several instabilities in the cardiopulmonary system, and that it is associated with mortality.

Abstract Background: The outbreak of coronavirus disease 2019 (COVID-19) began in December 2019 and is spreading rapidly. Rapid and accurate identification of suspected cases is critical in suppressing viral spread. We aimed to highlight the discrepancies in the varying criteria used by international agencies and highly impacted individual countries worldwide.Methods: The criteria from two international agencies and ten countries across Asia, Europe, and North America were reviewed. Each included information on the clinical causes of illness and epidemiology risk factors. Non-English language guidelines were translated into English by one of the co-authors who was fluent in that language. Results: Although the majority of criteria are modified from the World Health Organization recommendations, the specific clinical features and epidemiological risks for triggering evaluation of COVID-19 in suspected patients differed widely among nations. The rationale for these differences may be linked to each individual country’s resources, politics, experience with previous outbreaks or pandemics, health insurance systems, severity of the COVID-19 situation, and other undetermined factors. Conclusion: There was no consensus on the single best criteria for identifying a suspected case of COVID-19.
