Among disparate infectious diseases viral infection in particular challenges survival of mankind across the globe. By superseding those events, 2019 novel (CoVID-19) or SARS-CoV-2 has become a new human health crisis threatening the world. Corona viruses (CoV) are large family of viruses that affects birds and mammals. In humans, Corona virus can cause respiratory tract infection ranging from the common cold to more serious infection such as SARS (Severe acute respiratory syndrome), MERS (Middle East Respiratory Syndrome) and CoVID-19 (Corona Virus Disease 2019) which can also become lethal. The Novel corona virus (CoVID-19) originated in 2019, is a novel virus which has not been identified in humans since past. At present, the source of CoVID-19 is not known. Although the infection is presumed to be in origin, person to person transmission is evident. Many supportive and symptomatic therapies where being carried out by the Medical practitioners as per the instructions of World Health Organization (WHO) with a hypothesis and there is no evidence that it works against CoVID-19. best to lower the current crises of infection is prevention and many measures that boosts the immunity are following by the people as directed by the Ministry of AYUSH.

Corona Virus Disease-2019 commonly known as COVID-19 which has been defined by the Novel Corona Virus. It is a family of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) and was first detected during respiratory outbreak. It was first reported to the World Health Organization on December 31, 2019. On January 30, 2020, the World Health Organization declared the COVID-19 eruption a global health emergency. As of 27-May-2021 169,095,283 confirmed cases have been reported in the world and 2, 73, 67, 935 cases in India. It is required to identify the infection with high precision rate but there are lots of deficiency in the diagnosing system that may resulted false alarm rate. Initially it could be detected through throat saliva but now it can also be identified thought the impairment in lungs from computerized tomographical imaging technique. This paper reviewed various researches over COVID-19 diagnosis approach as well as the syndrome in respiratory organs. There are so many imaging techniques through which lungs impairments can be detected that may diagnose COVID-19 with high level of accuracy. CT scan image is the best alternative for diagnosing COVID-19.

The Impact

The World Health Organization (WHO) on March 11, 2020, has declared the novel Corona virus (COVID-19) outbreak a global pandemic. It is essential to understand how coronavirus transmits from one person to another and this knowledge will help protect the vulnerable and limit the spread of the Corona virus. The mode of respiratory transmission of Corona virus is not completely understood as of date. Using a computer simulation, this paper analyses the probability of spreading of Corona virus through air among the people who are standing in a queue. The parameters such as the diameter of the virus particle, room temperature, relative humidity, height of the person, distance between the people and the waiting time in the queue are considered in the computer model to determine the distribution of Corona virus and hence identify the risk factor of spreading the Covid-19. This paper describes the possibilities of getting infectious when a Covid-19 infected person present in a queue and the impact on the waiting time and the position in the queue on the transmission of Corona virus.

The coronavirus disease 2019 (COVID-19) pandemic is a general health crisis and has irreversible impacts on human societies. Globally, all people are at risk of being exposed to the novel coronavirus through transmission of airborne bioaerosols. Public health actions, such as wearing a mask, are highly recommended to reduce the transmission of infectious diseases. The appropriate use of masks is necessary for effectively preventing the transmission of airborne bioaerosols. The World Health Organization (WHO) suggests washing fabric masks or throwing away disposable masks after they are used. However, people often use masks more than once without washing or disposing them. The prolonged use of a single mask might—as a result of the user habitually touching the mask—promote the spread of pathogens from airborne bioaerosols that have accumulated on the mask. Therefore, it is necessary to evaluate how long the living components of bioaerosols can be viable on the masks. Here, we evaluated the viability of airborne Bacillus subtilis (B. subtilis) in bioaerosols filtered on woven and anti-droplet (non-woven) face masks. As a simulation of being simultaneously exposed to sand dust and bioaerosols, the viability rates of bioaerosols that had accumulated on masks were also tested against fine dust and airborne droplets containing bacteria. The bioaerosols survived on the masks immediately after the masks were used to filter the bioaerosols, and the bacteria significantly proliferated after one day of storage. Thereafter, the number of viable cells in the filtered bioaerosols gradually decreased over time, and the viability of B. subtilis in bioaerosols on the masks varied, depending on the mask material used (woven or non-woven). Despite the reduction in viability, bioaerosols containing living components were still found in both woven and anti-droplet masks even after six days of storage and it took nine days not to have found them on masks. The number of viable cells in bioaerosols on masks significantly decreased upon exposure of the masks to fine dust. The results of this study should provide useful information on how to appropriately use masks to increase their duration of effectiveness against bioaerosols.

(COVID2019). COVID-19 was officially recognized as a Pandemic by WHO on March 11, 2020. Plants have been used all over the world as traditional medicine for centuries to treat many chronic infections, including viral diseases. In recent years, scientists have been trying to verify the potential of functional compounds to protect human health and cure diseases with their research on functional and nutraceutical foods. Traditional medicinal plants have a long history supported by many researches such as maintaining a healthy life, toxins taken in daily life, fighting and preventing diseases, and longevity. Studies on the antiviral, antiinflammatory and antioxidant properties of ethnomedical plants and natural phytochemicals can be considered as a great potential drug source against various ailments as well as Covid-19 treatment. Based on this study, plant extracts increase immunity with the increase in the number of white blood cells and lymphocytes in viral infections such as Covid-19, which can lead to fatal consequences, regulating the production and release of proinflammatory cytokines, showing an anti-inflammatory effect with a decrease in the C-reactive protein and erythrocyte sedimentation rate, It appears to have a positive effect such as interfering with the development and potential antiviral agent activity. In this study, phytochemicals and effects associated with COVID-19 infection were reviewed.
