Watch your fever pattern with a thermometer. Do not share the thermometer, if you have to wipe it with some disinfectant. Take daily 3 measurements. If there is no fever, don’t worry. Take steam inhalation, home remedies; turmeric with honey and watch. If fever pattern is showing a rising trend that keeps coming back within 2 -3 hours of taking a paracetamol, please contact a doctor. If you have any difficulty in saying PA TA KA repeatedly for a minute, see a doctor. Don’t take self medication; HCQ or others, consult a doctor.
