Laziness with throat infection without fever is usually due to a mild viral illness and is less likely to be dengue or chikungunya at this stage. Take proper rest, drink warm fluids, do steam inhalation, eat light food, and stay hydrated to support recovery. Monitor for signs such as high fever, severe body aches, rash, or worsening weakness. If symptoms change or persist, or if you develop a fever, consult a doctor to be checked and rule out other infections.
