Some of the primary symptoms to look for in a Covid 19 infected person are fever, dizziness, breathlessness, headache, dry cough ( eventually result in phlegm) and in a few cases loss in smell and taste. A few cases have also reported diarrhoea and fatigue.
A healthy oxygen saturation level ranges between 95% and 100% . If a person's levels drop below this range, they may experience symptoms associated with a lack of oxygen, such as trouble breathing and confusion.
