This might help, which I picked up from Medscape:
Presentations of COVID-19 have ranged from no or mild symptoms to severe illness and mortality. Symptoms may develop 2 days to 2 weeks after exposure to the virus.
Although symptoms may occur in various orders and individuals do not necessarily have any or all symptoms, a study of more than 55,000 confirmed cases of COVID-19 reported that the most common order of symptoms was fever, cough, muscle pain, nausea/vomiting, and diarrhoea. This may help distinguish the presentation of COVID-19 from the presentation of influenza, which more commonly begins with cough and myalgia.
The following symptoms may indicate COVID-19:
- Fever or chills
- Cough
- Shortness of breath or difficulty breathing
- Fatigue
- Muscle or body aches
- Headache
- New loss of taste or smell
- Sore throat
- Congestion or runny nose
- Nausea or vomiting
- Diarrhoea
Other reported symptoms have included the following:
- Sputum production
- Malaise
- Respiratory distress
- Neurologic (eg, altered mentality)
Risk factors for severe COVID-19, regardless of age, include the following:
- Obesity (body mass index ≥ 30 kg/m2)
- Chronic kidney disease
- Chronic obstructive pulmonary disease (COPD)
- Immunocompromised state due to solid organ transplant
- Serious heart conditions (eg, heart failure, coronary artery disease, cardiomyopathies)
- Sickle cell disease
- Type 1 diabetes mellitus
- Type 2 diabetes mellitus
The following are underlying conditions that may represent an increased risk for severe COVID-19:
- Asthma (moderate to severe)
- Cerebrovascular disease
- Cystic fibrosis
- Immunocompromised state due to blood or bone marrow transplant, immunodeficiencies, HIV infection, corticosteroid use (or other medications that weaken the immune system)
- Neurologic conditions (eg, dementia)
- Liver disease
- Pregnancy
- Pulmonary fibrosis
- Smoking
- Thalassemia
