COVID-19 Symptoms;
COVID-19 manifests through a wide spectrum of symptoms, ranging from mild or moderate conditions to severe, rapidly worsening, and life-threatening presentations. The symptoms are generally non-specific, with cases varying from asymptomatic to severe pneumonia. Studies indicate that asymptomatic cases account for approximately 1.6% to 51.7%, wherein individuals do not exhibit noticeable clinical signs or symptoms, nor are there visible abnormalities in lung computed tomography scans.
The most frequently reported symptoms of COVID-19 include fever, dry cough, muscle pain (myalgia), and fatigue. Atypical symptoms may involve sputum production, headaches, vomiting, diarrhea, haemoptysis (coughing up blood), and sore throat. Some patients also report a runny nose (rhinorrhoea), confusion, or headaches as preliminary symptoms occurring prior to the onset of fever. These findings highlight fever as a significant symptom, though it may not always be the initial indicator of infection. Additionally, symptoms such as loss of smell (hyposmia) and taste (hypogeusia) are increasingly recognized as early warning signs, prompting recommendations for self-isolation.
