Symptoms of corona, or COVID-19, are signs of infection with the SARS-CoV-2 virus, ranging. Common symptoms include fever, cough, and fatigue, while serious cases may involve difficulty breathing or loss of speech.
COVID-19 symptoms typically appear 2-14 days after exposure. The virus attacks the respiratory system, causing inflammation and fluid buildup in the lungs. Early symptoms often resemble the flu, making diagnosis challenging without testing.
The Centers for Disease Control and Prevention (CDC) categorizes symptoms into three groups:
| Common Symptoms | Less Common Symptoms | Emergency Warning Signs |
|---|---|---|
| Fever, cough, fatigue, loss of taste or smell | Sore throat, congestion, nausea, diarrhea | Trouble breathing, persistent chest pain, confusion |
Loss of taste or smell (anosmia) is unique to COVID-19 and not typical in other respiratory illnesses like the flu or common cold.
Severity depends on factors like age, underlying health conditions, and virus variants. For example, the Delta variant caused more severe symptoms than earlier strains. Children often experience milder symptoms, while older adults are at higher risk for complications.
Seek emergency care if you or someone else shows signs of severe illness, such as trouble breathing or persistent chest pain. The CDC advises calling a healthcare provider if symptoms worsen or last longer than 10 days.
Understanding these differences helps ensure proper treatment and reduces unnecessary panic during respiratory illness outbreaks.
