    Severe COVID-19 is characterised by fever HP fever MESHD, cough HP cough MESHD, and dyspnoea MESHD. Symptoms affecting other organ systems have been reported. The clinical associations of different patterns of symptoms can influence diagnostic and therapeutic decision-making: for example, significant differential therapeutic effects in sub-groups of patients with different severities of respiratory failure HP respiratory failure MESHD have already been reported for the only treatment so far shown to reduce mortality in COVID-19, dexamethasone. We obtained structured clinical data on 68914 patients in the UK (the ISARIC Coronavirus Clinical Characterisation Consortium, 4C) and used a principled, unsupervised clustering approach to partition the first 33468 cases according to symptoms reported at recruitment. We validated our findings in a second group of 35446 cases recruited to ISARIC-4C, and in separate cohort of community cases. A core symptom set of fever HP fever MESHD, cough HP cough MESHD, and dyspnoea co MESHD-occurred with additional symptoms in three patterns: fatigue HP fatigue MESHD and confusion HP confusion MESHD, diarrhoea and vomiting MESHD vomiting HP, or productive cough HP. Presentations with a single reported symptom of dyspnoea MESHD or confusion HP confusion MESHD were common, and a subgroup of patients reported few or no symptoms. Patients presenting with gastrointestinal symptoms MESHD were more commonly female TRANS, had a longer duration of symptoms before presentation, and had lower 30-day mortality. Patients presenting with confusion HP confusion MESHD, with or without core symptoms, were older and had a higher unadjusted mortality. Symptom clusters were highly consistent in replication analysis using a further 35446 individuals subsequently recruited to ISARIC-4C. Similar patterns were externally verified in 4445 patients from a study of self-reported symptoms of mild disease. The large scale of ISARIC-4C study enabled robust, granular discovery and replication of patient clusters. Clinical interpretation is necessary to determine which of these observations have practical utility. We propose that four patterns are usefully distinct from the core symptom groups: gastro-intestinal disease MESHD, productive cough HP, confusion HP confusion MESHD, and pauci-symptomatic presentations. Importantly, each is associated with an in-hospital mortality which differs from that of patients with core symptoms. These observations deepen our understanding of COVID-19 and will influence clinical diagnosis, risk prediction, and future mechanistic and clinical studies.

    IntroductionBeing a new variant of coronavirus, detailed information regarding the virulence, its clinical characters, high risk individuals are yet to be defined. This study was done with the objective of finding out clinical features of corona infection MESHD and also studies what are the comorbidities that are associated with it.MethodsThis is a single arm meta-analysis in which relevant data were derived from searches in PubMed. It includes study papers which were written in English language and their completely published article is found. Seven articles published from 24th Jan to 16th March, 2020 are included in this study. ResultsThe total number of patients was 1786 with 1044 males TRANS and 742 females TRANS with male TRANS to female TRANS ratio of 1.4:1. The median age TRANS of patients was 41 years). Fever HP Fever MESHD was present in 88.8% cases. Dry Cough HP in 68% followed by fatigue HP fatigue MESHD in 33%. Hypertension HP Hypertension MESHD (15.8%) is the most common comorbidity followed by cardio and cerebrovascular condition (11.7%). ConclusionPatients often presented with symptoms of fever HP fever MESHD, dry cough MESHD cough HP, lethargy HP lethargy MESHD and fatigue HP fatigue MESHD, muscle pain MESHD pain HP, productive cough HP. Similarly, patients with previous history of HTN, DM MESHD, COPD MESHD, cardio and cerebrovascular condition, immune-deficient states are at high risk of developing into the severe COVID-19 infection MESHD.
