You can take paracetamol to manage fever and use calamine lotion or antihistamines to soothe itchy skin while your body naturally fights the virus. To protect others, stay at home and avoid contact with others, especially pregnant women or people with weakened immune systems, until all your blisters have fully scabbed over.

You can give your son paracetamol to reduce his fever and relieve discomfort, following the dosage instructions on the package for his age. Keep him well hydrated, ensure plenty of rest, and monitor for any worsening symptoms. If the fever lasts more than three days, or he has difficulty breathing, persistent vomiting, or seems very drowsy, please consult a paediatrician immediately.
