Symptoms:
The sign and symptoms of this infectious disease COVID-19 vary from mild to severe and at its peak severity where it mainly affects the lungs of affected person it may leads to death. The symptoms appear after the incubation period which is the time between exposure and the appearance of first symptom is about 5.2 days Fernandes and N (2020). The epoch as of the inception of the COVID-19 symptoms in the direction of death is from 6- 41 days by means of a norm about 14 days. The onset of symptoms of the disease and the death period is age dependent and immune status of the individual got infected. This period is shorter in the persons above 70 years of age then those under 70 years of age Klein, B et al (2020). It is significant to memorandum with the intention of the fact is that there must be some similarity in those of the symptoms flanked by the COVID-19 infection as well as former betacoronavirus like dry cough, dyspnea, fever, moreover as bilateral ground-glass opacities as in the CT scans of the chest Clay, J et al (2020). Conversely, COVID-19 appears to show various exceptional clinical experiences that embrace those of the affecting the lower airway as obvious by means of the symptoms of the upper respiratory tract like, sneezing, and rhinorrhoea along with the painful throat Fang, L et al (2020). Some most frequent symptoms which are at inception of the COVID-19 infirmity are those as fever, fatigue as well as cough Tian, S et al (2020), whereas supplementary symptoms consist of sputum production, haemoptysis, headache, diarrhea, as well as lymphopenia. Clinical experience exposed through the of the chest CT- scan offered as that the pneumonia, though, as there seems to be some unusual features like those of RNAaemia Shereen, M et al (2020) acute cardiac injury, acute respiratory syndrome in addition to occurrence of the grand-glass opacities which is a leading cause of death. In a number of infected patients, the various peripheral ground-glass opacities were also seen in those of the sub pleural areas of the lungs as that probable initiated both localized as well as systemic type of immune response so as to cause amplified the inflammation Shi, Y et al (2020). Unfortunately, in some cases the treatment by means of interferon inhalation appears to have no clinical consequences moreover it appears to exacerbate the circumstances by moving ahead to the pulmonary opacities Bernheim, A et al (2020).
The results from the radiograph of chest also had shown the infiltrate in the upper lobes of lungs which may results in the occurrence of the dyspnea as well as hypoxemia Ng, M et al (2020). The patients suffering from the infection of COVID-19 also developed the GI (gastrointestinal) symptoms as those of diarrhea and abdominal pain etc. but these GI symptoms were less likely to be associated with those MERS-COV or SARS-COV patients Tian, S et al (2020). Consequently, it is imperative to check fecal as well as urine samples in the direction of to eliminate an impending substitute means of spread, particularly from the health care workers as well as patients Lei, S et al (2020). Consequently, progress of methods to recognize the diverse ways of spread like those of fecal along with urine samples are immediately defensible for the development of the ways to inhibit or minimize the transmission and it will also helpful in the development of therapeutic strategies to control the disease Zhang, L et al (2020).
Some other symptoms as decrease in oxygen saturation and the coughing leads the patient to use oxygen or if in serious condition may be the use ventilator to stable the patient’s condition and the symptoms may get worse if not treated properly or the person is already suffering from some other chronic disease as co-morbidity may leads to the chronic conditions Hu, Z et al (2020).
