How can one best describe the symptoms of Covid-19?

The symptoms of Covid-19 are best described as similar to respiratory illnesses because the virus primarily affects the respiratory system. Common symptoms associated with Covid-19 include cough, shortness of breath, difficulty breathing, and other upper respiratory symptoms like sore throat and congestion. Additionally, Covid-19 may lead to pneumonia, a condition that also primarily impacts the lungs and can manifest similarly to other respiratory conditions.

Understanding this context is key. While nausea and vomiting can occur with Covid-19, they are not the hallmark symptoms; instead, they are less common and cannot be deemed characteristic of the disease. Skin infections are also not associated with Covid-19, as it does not typically present with skin-related symptoms unless it is a secondary complication. The assertion that symptoms are "only present in severe cases" overlooks the fact that many individuals may display mild or even asymptomatic cases, which can still contribute to the spread of the virus. Therefore, the description of Covid-19 symptoms aligns closely with respiratory illnesses, highlighting the respiratory nature of the disease.
