Here is a brief explanation about how the virus manifests depending on the stage of the infection.
Statistics show that 80% of all cases of COVID-19 are mild cases. The basic symptoms of a mild coronavirus infection are fever, respiratory symptoms like dry cough and body aches. The fever might take a few days to show. A mild infection does not necessarily make you want to go to a hospital. Most of the cases can be cured at this stage. However, with elderly people and those who have underlying medical conditions, it may progress to show moderate symptoms which may be respiratory aids to stabilize.
Moderate cases of the coronavirus infection usually manifest with symptoms like coughing, fever about 100, chills and shortness of breath. Hospitalization, in this case is also unlikely unless the patient has difficulty breathing or is dehydrated. You can identify dehydration with a dry mouth, dry skin or dizziness. Sometimes, moderate stages of the infection also develop into a mild of pneumonia. In such cases, pneumonia leads to a stage when patients might need respiratory aid. They are also susceptible to secondary bacterial infections.
One in five patients get to the stage of experiencing severe symptoms. About 14% of patients require respiratory support and 6% go into septic shock. Septic shock is a state of a significant drop in blood pressure leading to strokes, heart and lung failure and can lead to death. The infection can worsen to these severe symptoms anywhere between a few hours to several days. In many cases, it manifests in the form of a severe form of pneumonia.
The elderly and people with underlying medical conditions are more susceptible to the infection. It is advisable to see a doctor the moment you begin to experience symptoms. It is important to follow the guidelines laid down by the WHO to contain the spread of the pandemic.
