Corona virus disease – a short review

Abstract

Coronaviruses are RNA viruses that are phenotypically and genotypically diverse. This virus will cause the antiviral T-cell response to be erratic, owing to the T-cell apoptosis activation, triggering the immune system to collapse. The transmission of virus mainly occurs through the respiratory droplets of the infected person as he sneezes. Most of the infected people experience mild to moderate respiratory symptoms and recover without any special treatment. However, some will become seriously ill and require medical attention. Older people and those with underlying medical conditions like cardiovascular disease, diabetes, chronic respiratory disease, or cancer are more likely to develop serious illness. Anyone can get infected with COVID-19 and become seriously ill or die at any age. Presentations of COVID-19 include fever, cough, shortness of breath, malaise and respiratory distress. The best way to prevent the disease and slow down its transmission is to be well informed about the disease and how the virus spreads..
