Abstract Background Coronavirus disease 19 is a viral infection caused by a novel coronavirus, SARS-CoV-2. It was first notified in Wuhan, China, is now spread into numerous part of the world. Thus, the world needs urgent support and encouragement to develop a vaccine or antiviral treatments to combat the atrocious outbreak. Main body of the abstract The origin of this virus is yet unknown; however, rapid transmission from human-to-human “Anthroponosis” has widely confirmed. The world is witnessing a continuous hike in SARS-CoV-2 infection. In light of the outbreak of coronavirus disease 19, we have aimed to highlight the basic and vital information about the novel coronavirus. We provide an overview of SARS-CoV-2 transmission, timeline and its pathophysiological properties which would be an aid for the development of therapeutic molecules and antiviral drugs. Immune system plays a crucial role in virus infection in order to control but may have dark side when becomes uncontrollable. The host and SARS-CoV-2 interaction describe how the virus exploits host machinery and how overactive host immune response can cause disease severity also addressed in this review. Short conclusion Safe and effective vaccines may be the game-changing tools, but in the near future wearing mask, washing hands at regular intervals, avoiding crowed, maintaining physical distancing and hygienic surrounding, must be good practices to reduce and break the transmission chain. Still, research is ongoing not only on how vaccines protect against disease, but also against infection and transmission.

Background: It is known that Vitamin D can increase the body’s immunity against some viral infections. Many people around the world have vitamin D deficiency and, therefore, this has become a public concern whether vitamin D is an important factor protecting against COVID-19 infection. In this paper, the data about the roles of vitamin D on immunity and recovery from viral infections, especially novel Coronavirus disease (COVID-19) is reviewed. Methods: The electronic databases of Pubmed, Google Scholar, Research Gate, Excerpta Media Database (EMBASE) and Medical and Health Education (Medrix) were searched. Results: Vitamin D is considered an important factor in immune homeostasis. Various effects have been considered for this nutrient on the immune system, particularly because of vitamin D receptor (VDR) and Cytochrome P450 Family 27 Subfamily B Member 1 (CYP27B1) expression in most of the immune cells. Vitamin D can raise cellular immunity, reduce cytokine storm and enhance antioxidants production. It also has modulatory effects on Angiotensin-converting enzyme 2 (ACE2) receptors and might have protective functions against acute lung injuries, including COVID-19 infection. However, there are some articles against this positive effect. Conclusion: Vitamin D supplementation is reported to be effective in the enhancement of the immune system and might be effective in the treatment and prevention of COVID-19 infection, especially in those with its deficiency. However, it should be considered that vitamin D deficiency shows the overall health status of the patients and cannot be considered specific for COVID-19 infection.

Viral infections have afflicted human health and despite great advancements in scientific knowledge and technologies, continue to affect our society today. The current coronavirus (COVID-19) pandemic has put a spotlight on the need to review the evidence on the impact of nutritional strategies to maintain a healthy immune system, particularly in instances where there are limited therapeutic treatments. Selenium, an essential trace element in humans, has a long history of lowering the occurrence and severity of viral infections. Much of the benefits derived from selenium are due to its incorporation into selenocysteine, an important component of proteins known as selenoproteins. Viral infections are associated with an increase in reactive oxygen species and may result in oxidative stress. Studies suggest that selenium deficiency alters immune response and viral infection by increasing oxidative stress and the rate of mutations in the viral genome, leading to an increase in pathogenicity and damage to the host. This review examines viral infections, including the novel SARS-CoV-2, in the context of selenium, in order to inform potential nutritional strategies to maintain a healthy immune system.

The risk of viral transmission in the built environment is a matter of concern in the era of the novel coronavirus pandemic, for most of society, given that humans spent the majority of their time indoors. For pharmaceuticals and healthcare, there is an additional concern about working in cleanrooms and the degree to which protective measures are appropriate. With cleanrooms, an important concern is with the efficacy of HEPA filters. This article looks at the risks stemming from SARS-CoV-2 and applies these to the cleanroom context. The article concludes that the cleanroom environment does not contribute to the risk of viral transmission, and certain design aspects can, in fact, reduce the risk compared with other built environments. Characteristics of the novel coronavirus Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and SARS-CoV). Coronaviruses are zoonotic, meaning they can be transmitted between animals and people ¹. Coronaviruses are classified as RNA ‘enveloped’ viruses, whereas viruses such as rotavirus, or poliovirus are termed non-enveloped. Enveloped viruses have an envelope or outer coating which is needed by the virus to help it attach to the host cell. If this outer coating is destroyed, for example by a disinfectant, the virus cannot survive. The mode of transmission for enveloped viruses is characterized by the specific virus; however, the most common routes are via indirect or direct contact of infectious virus particles, contact with or inhalation of respiratory droplets ². The specific coronavirus of concern is SARS-CoV-2, with SARS standing for ‘severe acute respiratory syndrome’ and CoV representing ‘coronavirus’. The associated respiratory disease is termed COVID-19 (to represent ‘coronavirus disease 2019). This particular virus can cause severe respiratory disease because cells in the lung are damaged and no longer able to transport oxygen into the bloodstream. Some symptoms of disease such as fever and fatigue result from the activities of the immune system trying to eliminate the infection from the body. Heat (fever) inactivates viruses and fatigue results from the high energy demands of the immune system fighting the virus ³.

This review aimed to focus on using foods to boost immunity against COVID-19 in all age groups. In human, coronavirus causes the common cold, severe acute respiratory syndrome (SARS), and a major threat to public health. The novel coronavirus was declared a pandemic by the World Health Organization due to its rapid infectivity. COVID-19 infection is most probably reported in people with low immunity response. The nutrients, which show beneficial effects on the immune system, are called immune nutrients and diet is called immune diet. A healthy diet can reduce the risk of infection of COVID-19 and can prevent disease. Nutritional food intake is also necessary for people with chronic illness, obese persons, diabetes, cardiovascular disease, cognitive dysfunction like anxiety and depression. All nutrients are essential for maintaining immunity and providing appropriate amounts of protein, fat, carbohydrate, vitamins, and minerals for the surveillance mode of keeping us from getting sick. The use of plenty of water, minerals such as micronutrients, zinc, copper, selenium, iron, magnesium, food rich in vitamins, and a good lifestyle can promote health and overwhelm this coronavirus infection.

UNSTRUCTURED The novel coronavirus 2019-nCoV/SARS-CoV-2 that has caused the outbreak of the coronavirus disease, COVID-19, has created an alarming situation around the world, including India. Vitamin D is a hormone precursor that plays an important role in adaptive immunity, cellular differentiation, maturation, and proliferation of immune cells. The optimum level of vitamin D could be a potential lead to fight against SARS-CoV-2 infection. In the Indian subcontinent, Vitamin D deficiency prevails in wide-ranging proportions, with a prevalence of 70%–100%. Vitamin D produced in the skin by sunlight/ultraviolet B (UV-B) radiation (290–320nm) may last in the blood twice compared with supplementary vitamin D, wherein consuming vitamin D through supplementary source may lead to toxicity. Balancing vitamin D levels between normal ranges will be effective and cheap to control and/or to prevent respiratory tract infections (RTIs). Although, if we talk about India, it is challenging to provide vitamin D through the supplementary source to every individual, and also it will not be affordable for people of below poverty line (BPL). Therefore, the optimum level of vitamin D could be a potential lead to fight against SARS-CoV-2 infection, which could be achieved by proper exposure to sunlight (preferably in the morning) for 10-20 min daily.

COVID-19 is the current pandemic caused by the novel coronavirus, SARS-CoV-2, that emerged from China at the end of December 2019. The scientific community is making extraordinary efforts to understand the virus structure and the pathophysiology and immunological processes activated in the host, in order to identify biomarkers, diagnostic tools, treatments, and vaccines to decrease COVID-19 incidence and mortality. Various abnormalities have been noted during SARS-CoV-2 infection both in lymphoid and myeloid cells. Such abnormalities may disturb the immune system function and cause a massive inflammatory response that impairs tissue function. This review discusses the close relationship between the immune system abnormalities and the broad spectrum of clinical manifestations, including fibrosis, in the context of COVID-19 disease. Moreover, we described the current strategies for COVID-19 diagnosis, and we provide a summary of the most useful clinical laboratory parameters to identify severe COVID-19 patients.
