Gastrointestinal symptoms were also prominent. 6 patients reported diarrhea, and 5 reportedvomiting during the course of their illness. Results of the study are shown in table 3.Control and prevention of Covid-19SARS-CoV affects more than 8000 people as well as 774 people dies because of SARS in 2002.To control SARS-CoV virus infection-control measures are taken but the problem is that it canalso reappear because of the reason that agent that causes it is also present in some animals(Bukreyev et al., 2004) (Hsu et al., 2003).There is epidemiological and clinical proof to propose various novel mixtures, just asprescriptions authorized for different conditions, that seem to have possible viability in contrastto SARS-CoV-2 (Prete et al., 2020). Still, without a safe as well as powerful antibody ormedication, diminishing transmission through virus is the main methodology accessible whereover-all training, and executing the proper counteraction and control is critical (Khafaie &Rahim, 2020). Precautionary measures can help smother the danger of contamination, for example, washing thehands as often as possible with cleanser and water or by a disinfectant gel based on alcohol,coughing into the elbow or a collapsed tissue, keeping a distance from close interaction with theindividuals who have manifestations, and self-disengaging, however clinical assistance must belooked if one experiences trouble in breathing (Khafaie & Rahim, 2020). We can prevent thespread of SARS-CoV-2 by lockdown in country in order to lessen the spread of confirmed casesof SARS-CoV-2 (Zhang et al., n.d.).10| Page
Phylogenetic analysis:SARS-CoV including SARS-CoV-2 belongs to a genus named as betacoronavirus genus andboth are phylogenetically associated with bat SARS-like coronavirus. Both share almost 79%genetic similarity. Furthermore, SARS-CoV-2is almost 96% comparable to total-genome of a batcoronavirus (Li et al., 2005). Pairwise protein sequence alignment of 7 non-structural proteinsconserved domains reveals that this virus has its place in the species of SARS-CoV. SARS-CoVincluding SARS-CoV-2 share alike infection pathophysiology in humans because both of thembind to the same human receptor, angiotensin-converting enzyme 2 (ACE2), for entry into hostcells (Zhou et al., 2020).A small area of RNA polymerase dependent on RNA that is represented as RdRp was found froma bat coronavirus that was recently recognized in Rhinolophus affinis from Yunnan regiondemonstrated extraordinary grouping character to SARS-CoV-2. Full-length sequencing wasdone on RNA test having the GISAID promotion number EPI_ISL_402131. Simplotexamination indicated that SARS-CoV-2 was profoundly comparative all through genome toRaTG13, having a general genome sequence identity of 96.2%. Utilizing the genomearrangements of SARS-CoV-2 that were aligned, RaTG13 was recently announced bat SARS-CoV, no proof for recombination occasions was identified in the genome of SARS-CoV-2 (Zhouet al., 2020).
